Transclusion is a powerful feature in MediaWiki that allows content from one page to be included (or "transcluded") into another page. It's a core mechanism for creating reusable templates, managing consistent information across multiple pages, and building dynamic content. This guide will provide a comprehensive overview of transclusion, aimed at beginners, covering its principles, syntax, use cases, limitations, and best practices. Understanding transclusion is crucial for anyone wanting to contribute effectively to a wiki, especially when dealing with complex page structures and maintaining consistency.
At its heart, transclusion is *not* copying and pasting content. Instead, it's a reference to the original content. When a page is transcluded, the *current* version of the original page is displayed wherever the transclusion code is placed. This means that if the original page is edited, all pages that transclude it will automatically reflect those changes. Think of it like a shortcut or a live link to content, rather than a static copy.
This differs fundamentally from copy-pasting. Copy-pasting creates multiple independent copies of the content. Changes to one copy do *not* affect the others. Transclusion creates a single source of truth, ensuring consistency and reducing maintenance effort.
The fundamental syntax for transclusion is using double curly braces: `
Template:Page Name
Template:Page Name is a fundamental and incredibly useful MediaWiki template that allows you to dynamically display the name of the current page within a wiki. While seemingly simple, it has a wide range of applications, from creating navigational aids to generating dynamic content based on the page title. This article will provide a comprehensive guide to understanding and utilizing the `Page Name` template, geared towards beginners. We'll cover its basic usage, variations, common use cases, troubleshooting, and advanced techniques. This will be particularly useful for those building complex templates or wiki structures.
What does Template:Page Name do?
At its core, `Template:Page Name` resolves to the title of the page on which it is placed. It's a parser function, meaning it's processed by the MediaWiki software during page rendering. The result is a string containing the page title, which can then be used in various ways within the wiki content. Crucially, it doesn't display the full namespace; by default, it shows only the page *name* within its namespace. This distinction is important and will be elaborated upon later. Understanding how this works is the first step towards mastering more complex template functionality, such as Template:Full Page Name.
Basic Usage
The most basic way to use the template is simply to transclude it:
If you place this code on the page "Help:Contents", it will display:
`Help:Contents`
Notice that it displays the entire page title, including the "Help:" namespace. This is the default behavior. However, as mentioned, you often want just the page name *without* the namespace.
Removing the Namespace
The `Page Name` template has a parameter that allows you to strip the namespace. You use the `|` (pipe) character to pass this parameter:
Using the same example on the "Help:Contents" page, this will now display:
`Contents`
This is often the desired behavior when you want to refer to the page's content without explicitly mentioning its namespace. This is crucial for building consistent and user-friendly interfaces. Consider using this when creating dynamic table of contents or navigation sections. It’s also essential when working with Template:Current Month or other templates needing just the core page identifier.
Variations and Parameters
While `no namespace` is the primary parameter, there are other techniques to achieve similar results or customize the output further. These often involve combining `Page Name` with other parser functions.
**Using `subst:`:** The `subst:` magic word can be used to *substitute* the template's output directly into the page content. This means the template code is replaced with its rendered value, making it static. This is useful if you want to permanently store the page name at a specific point in time. However, it will not update if the page title changes.
**Combining with `string-format`:** The `string-format` parser function allows you to manipulate the output of `Page Name`. For example, you can convert the page name to uppercase or lowercase.
This would display the page name in all uppercase letters. This is particularly useful for creating titles or headings with a consistent style. You can also use `string-format` to add prefixes or suffixes to the page name. Understanding Template:String Format is vital for advanced customization.
**Combining with `#if`:** You can use the `#if` parser function to conditionally display the page name based on certain criteria.
This will display "This is the page: [Page Name]" if the page name exists; otherwise, it will display "Page name is empty." This can be useful for handling special cases, such as empty pages or redirect pages.
Common Use Cases
`Template:Page Name` has numerous applications within a MediaWiki environment. Here are some common examples:
**Creating Dynamic Table of Contents:** You can use `Page Name` to generate a table of contents that automatically reflects the current page's structure. This is often used in conjunction with heading levels and other parser functions.
**Building Navigational Aids:** You can create links to related pages based on the current page name. For example, you could create a template that displays links to the current page's talk page, history page, or edit page. This enhances user experience and simplifies navigation.
**Generating Dynamic Titles:** You can use `Page Name` to create dynamic titles for sections or pages. This can be useful for creating templates that are used across multiple pages with different titles. Consider its use with Template:Title for more complex title generation.
**Creating Consistent Headers and Footers:** You can use `Page Name` to display the current page name in a header or footer, providing a consistent visual cue for users.
**Automated Categorization:** Although categories are often added manually, `Page Name` can be used in conjunction with other templates to automate the categorization process based on the page title.
**Error Handling and Reporting:** You can use `Page Name` to include the current page name in error messages or reports, making it easier to identify the source of the problem.
**Creating Dynamic Infoboxes:** Infoboxes can be made more dynamic by incorporating the page name into their content. This helps to ensure that the infobox is relevant to the current page.
**Log Files and Tracking:** `Page Name` can be used in templates that generate log files or track page views, providing valuable data for wiki administrators. This is often used with extensions like Extension:PageView.
**Template Documentation:** Using `Page Name` within template documentation examples helps illustrate how the template works in different contexts.
**Automated Indexing:** Creating automated indexes or lists of pages based on their names.
Troubleshooting
While `Page Name` is a relatively simple template, you may encounter issues when using it. Here are some common problems and their solutions:
**Incorrect Namespace:** If you're getting the full page title instead of just the page name, make sure you're using the `|no namespace` parameter correctly. Double-check the syntax and ensure there are no typos.
**Template Not Rendering:** If the template isn't rendering at all, check the following:
* Make sure the template page exists and is not protected.
* Check for syntax errors in the template code.
* Ensure that the template is being transcluded correctly (using `Template loop detected: Template:Page Name`).
* Check for conflicting templates or parser functions.
**Unexpected Output:** If you're getting unexpected output, carefully review your template code and the surrounding content. Make sure you're not accidentally passing incorrect parameters or using conflicting functions. Use the MediaWiki debugger to step through the code and identify the source of the problem. Template:Debugger can be helpful.
**Caching Issues:** Sometimes, changes to templates may not be reflected immediately due to caching. Try purging the page cache by editing the page and saving it, or by using the `?action=purge` parameter in the URL.
**Circular References:** Avoid creating templates that recursively call themselves, as this can lead to infinite loops and errors.
**Compatibility Issues:** Some extensions or custom code may interfere with the `Page Name` template. If you suspect this is the case, try disabling the extension or custom code to see if it resolves the issue.
Advanced Techniques
Once you're comfortable with the basics of `Page Name`, you can explore more advanced techniques:
**Using `#titleparts`:** The `#titleparts` parser function allows you to extract specific parts of the page title. This can be useful for creating more complex templates that need to manipulate the page name in a granular way.
**Combining with Regular Expressions:** You can use regular expressions to match and extract specific patterns from the page name. This can be useful for creating templates that need to process page names with a specific format.
**Creating Custom Templates:** You can create your own custom templates that encapsulate the `Page Name` functionality and add additional features. This can help to simplify your wiki code and improve maintainability.
**Utilizing Lua Modules:** For more complex logic and performance optimization, you can use Lua modules to implement the `Page Name` functionality. Lua provides a more powerful and flexible programming environment than the built-in parser functions. Extension:Lua is required for this.
**Conditional Logic with `#switch`:** The `#switch` parser function can be used to perform different actions based on the value of the page name. This allows you to create templates that behave differently depending on the page they are used on.
**Data Retrieval with API Integration:** You can combine `Page Name` with the MediaWiki API to retrieve data about the current page, such as its revision history or associated categories. This allows you to create dynamic templates that are linked to external data sources.
Best Practices
**Keep it Simple:** Avoid unnecessary complexity when using `Page Name`. The simpler the template, the easier it will be to understand and maintain.
**Document Your Code:** Clearly document your template code, explaining its purpose, parameters, and usage. This will help other wiki editors understand and modify your code in the future.
**Test Thoroughly:** Thoroughly test your template on different pages to ensure it works as expected. Pay attention to edge cases and potential errors.
**Use Comments:** Use comments to explain complex sections of your code. This will make it easier to understand and maintain.
**Follow Wiki Style Guidelines:** Follow the wiki's style guidelines when creating templates. This will help to ensure consistency and readability.
**Consider Performance:** Be mindful of the performance impact of your templates. Avoid using excessively complex code or making unnecessary API calls.
**Use Namespaces Wisely:** Understand the implications of using namespaces and how they affect the output of `Page Name`.
By following these guidelines, you can create robust and maintainable templates that enhance your MediaWiki wiki. Remember that consistent application of these principles will lead to a more organized and scalable wiki environment. You should also explore Template:Variables and Template:Parameters for further understanding of template construction.

The "Page Name" is case-sensitive. "Page Name" is different from "page name".
If the page doesn't exist, the transclusion will typically display a red error message indicating that the page is missing. This is a useful indicator of broken links or typos.
For example, if you have a page called "Standard Disclaimer" containing a legal disclaimer, you can transclude it into multiple pages by simply adding `Template:Standard Disclaimer` wherever you want the disclaimer to appear. If the legal wording of the disclaimer needs to be updated, you only need to edit the "Standard Disclaimer" page once, and the changes will be reflected on all pages where it's transcluded.
Transcluding Specific Parts of a Page
Often, you don't want to transclude the entire contents of a page. You might only want to include a specific section or a table. MediaWiki provides several ways to achieve this:

**Generating Dynamic Titles:** You can use `Page Name` to create dynamic titles for sections or pages. This can be useful for creating templates that are used across multiple pages with different titles. Consider its use with Template:Title for more complex title generation.
**Creating Consistent Headers and Footers:** You can use `Page Name` to display the current page name in a header or footer, providing a consistent visual cue for users.
**Automated Categorization:** Although categories are often added manually, `Page Name` can be used in conjunction with other templates to automate the categorization process based on the page title.
**Error Handling and Reporting:** You can use `Page Name` to include the current page name in error messages or reports, making it easier to identify the source of the problem.
**Creating Dynamic Infoboxes:** Infoboxes can be made more dynamic by incorporating the page name into their content. This helps to ensure that the infobox is relevant to the current page.
**Log Files and Tracking:** `Page Name` can be used in templates that generate log files or track page views, providing valuable data for wiki administrators. This is often used with extensions like Extension:PageView.
**Template Documentation:** Using `Page Name` within template documentation examples helps illustrate how the template works in different contexts.
**Automated Indexing:** Creating automated indexes or lists of pages based on their names.
Troubleshooting
While `Page Name` is a relatively simple template, you may encounter issues when using it. Here are some common problems and their solutions:
**Incorrect Namespace:** If you're getting the full page title instead of just the page name, make sure you're using the `|no namespace` parameter correctly. Double-check the syntax and ensure there are no typos.
**Template Not Rendering:** If the template isn't rendering at all, check the following:
* Make sure the template page exists and is not protected.
* Check for syntax errors in the template code.
* Ensure that the template is being transcluded correctly (using `Template loop detected: Template:Page Name`).
* Check for conflicting templates or parser functions.
**Unexpected Output:** If you're getting unexpected output, carefully review your template code and the surrounding content. Make sure you're not accidentally passing incorrect parameters or using conflicting functions. Use the MediaWiki debugger to step through the code and identify the source of the problem. Template:Debugger can be helpful.
**Caching Issues:** Sometimes, changes to templates may not be reflected immediately due to caching. Try purging the page cache by editing the page and saving it, or by using the `?action=purge` parameter in the URL.
**Circular References:** Avoid creating templates that recursively call themselves, as this can lead to infinite loops and errors.
**Compatibility Issues:** Some extensions or custom code may interfere with the `Page Name` template. If you suspect this is the case, try disabling the extension or custom code to see if it resolves the issue.
Advanced Techniques
Once you're comfortable with the basics of `Page Name`, you can explore more advanced techniques:
**Using `#titleparts`:** The `#titleparts` parser function allows you to extract specific parts of the page title. This can be useful for creating more complex templates that need to manipulate the page name in a granular way.
**Combining with Regular Expressions:** You can use regular expressions to match and extract specific patterns from the page name. This can be useful for creating templates that need to process page names with a specific format.
**Creating Custom Templates:** You can create your own custom templates that encapsulate the `Page Name` functionality and add additional features. This can help to simplify your wiki code and improve maintainability.
**Utilizing Lua Modules:** For more complex logic and performance optimization, you can use Lua modules to implement the `Page Name` functionality. Lua provides a more powerful and flexible programming environment than the built-in parser functions. Extension:Lua is required for this.
**Conditional Logic with `#switch`:** The `#switch` parser function can be used to perform different actions based on the value of the page name. This allows you to create templates that behave differently depending on the page they are used on.
**Data Retrieval with API Integration:** You can combine `Page Name` with the MediaWiki API to retrieve data about the current page, such as its revision history or associated categories. This allows you to create dynamic templates that are linked to external data sources.
Best Practices
**Keep it Simple:** Avoid unnecessary complexity when using `Page Name`. The simpler the template, the easier it will be to understand and maintain.
**Document Your Code:** Clearly document your template code, explaining its purpose, parameters, and usage. This will help other wiki editors understand and modify your code in the future.
**Test Thoroughly:** Thoroughly test your template on different pages to ensure it works as expected. Pay attention to edge cases and potential errors.
**Use Comments:** Use comments to explain complex sections of your code. This will make it easier to understand and maintain.
**Follow Wiki Style Guidelines:** Follow the wiki's style guidelines when creating templates. This will help to ensure consistency and readability.
**Consider Performance:** Be mindful of the performance impact of your templates. Avoid using excessively complex code or making unnecessary API calls.
**Use Namespaces Wisely:** Understand the implications of using namespaces and how they affect the output of `Page Name`.
By following these guidelines, you can create robust and maintainable templates that enhance your MediaWiki wiki. Remember that consistent application of these principles will lead to a more organized and scalable wiki environment. You should also explore Template:Variables and Template:Parameters for further understanding of template construction.

' This tag defines content that should *only* be included when the page is transcluded, and not when the page is viewed directly. This allows you to create pages that function as templates but also have their own standalone content. For example:
```wiki
This is the main content of the page.
```
... This tag defines the *only* content that should be included when the page is transcluded. Content outside of the `` tags will be ignored during transclusion. This is extremely useful for creating focused templates.
```wiki
This content will be ignored during transclusion.
This is the content that will be transcluded.
This content will also be ignored during transclusion.
```
Sections: To transclude a specific section of a page, you can use the section name after the page name, separated by a colon (`:`). For example, `Template:Page Name:Section Name` will transclude only the content within the section titled "Section Name" on the page "Page Name". Section names are case-sensitive and must match the actual section heading exactly.
Parameters and Templates
Transclusion becomes even more powerful when combined with parameters. This allows you to create flexible templates that can be customized for different uses.
Templates: Pages specifically designed for transclusion are often called "templates". They typically use parameters to allow for variable content. Templates are usually stored in the [[Template:]] namespace.
Parameters: Parameters are variables that you can pass to a template when you transclude it. They allow you to customize the output of the template. Parameters are defined using the syntax `{{{1}}}`, `{{{2}}}`, etc. within the template.
Calling Templates with Parameters: When transcluding a template with parameters, you specify the values for the parameters after the template name, separated by pipes (`|`). For example, `Template:Template Name`.
Consider a template called "Template:Infobox" designed to display information about a topic. The template might contain:
Template:Infobox is a core component of MediaWiki used to create standardized summary boxes, typically displayed in the upper-right corner of an article. These boxes, known as infoboxes, present essential information about the article's subject in a structured and easily digestible format. This article will guide beginners through understanding, creating, and utilizing infoboxes effectively.
What is an Infobox?
An infobox is essentially a Template that defines a specific layout for presenting data. It's designed to quickly convey key facts, such as dates, locations, characteristics, or relevant statistics. Think of it as a snapshot of the most important information, allowing readers to grasp the core details without having to read the entire article.
Infoboxes are particularly useful for:
Biographies: Displaying birthdates, places of birth, occupations, and notable achievements.
Geographical Locations: Presenting coordinates, population, area, and other geographical data.
Organizations: Listing founding dates, headquarters locations, and types of organizations.
Scientific Concepts: Summarizing key properties, classifications, and discoveries.
Films/Books/Games: Displaying release dates, directors/authors, and genre information.
Why Use Infoboxes?
Consistency: Infoboxes promote a consistent look and feel across all articles on a wiki, making it easier for readers to find information. A standardized format is crucial for usability.
Readability: They present information in a clear and concise manner, improving readability and comprehension.
Quick Overview: Infoboxes provide a quick overview of the subject, allowing readers to quickly assess its relevance to their interests.
Data Retrieval: They facilitate data retrieval and analysis, as the information is structured in a predictable format. This is important for Semantic MediaWiki extensions.
Navigation: Infoboxes often contain links to related articles, improving navigation within the wiki.
Understanding the Syntax
Infoboxes are created using MediaWiki's template system. The basic syntax involves using the `{{Infobox` tag, followed by parameters that define the content and layout of the box. Let's break down the key elements:
`{{Infobox` : This opens the infobox template.
`title =` : Specifies the title of the infobox. This is the heading that appears at the top of the box.
`image =` : Specifies the filename of an image to be displayed in the infobox. Use the `File:ImageName.jpgwidth=px` format *within* the parameter value.
`caption =` : Provides a caption for the image.
`header =` : Defines a header for a section within the infobox. You can have multiple `header` parameters to create distinct sections.
`content =` : The main body of the infobox. This is where you'll enter the key information about the subject. You can use standard MediaWiki formatting (e.g., wikilinks, bold text, *italic text*) within the `content` parameter.
`label1 =` , `data1 =` , `label2 =` , `data2 =` , etc.: This is the most common way to define key-value pairs within an infobox. `label1` is the name of the data field (e.g., "Born"), and `data1` is the corresponding value (e.g., "January 1, 1990").
`}}` : This closes the infobox template.
A Simple Example
Let's create a simple infobox for a fictional character named "Alex Johnson":
This code will generate an infobox with the title "Alex Johnson", an image, and two sections: "Personal Information" and "Skills". The "Personal Information" section will display the birthdate, occupation, and nationality, while the "Skills" section will provide a brief description of the character's abilities.
Technical analysis often relies on quickly digestible data, making infoboxes ideal for summarizing key statistical information about assets. For example, an infobox for a stock could include data on its Price-to-Earnings ratio, Dividend Yield, and Beta.
Creating More Complex Infoboxes
Infoboxes can become much more complex, with multiple sections, images, and data points. Here are some advanced techniques:
Using Parameters for Reusability: Instead of hardcoding all the data directly into the infobox, you can define parameters for each piece of information. This makes the infobox more reusable and easier to update.
Conditional Statements: You can use conditional statements (e.g., `#if:`, `#switch:`) to display different information based on the value of a parameter. This allows you to create infoboxes that adapt to different types of subjects.
Templates Within Templates: You can nest templates within infoboxes to create even more complex layouts and functionality.
Using Classes for Styling: You can apply CSS classes to different elements of the infobox to customize its appearance.
Using Existing Infobox Templates
Before creating a new infobox from scratch, it's always a good idea to check if an existing template already meets your needs. Many wikis have a library of pre-built infoboxes for common topics.
To find existing infobox templates:
1. Search the Template Namespace: Go to the `Template:` namespace (e.g., `Template:Infobox Person`, `Template:Infobox Country`). You can use the search function to find templates related to your topic.
2. Browse Category:Templates: Many wikis categorize templates. Look for categories like `Category:Templates` or `Category:Infobox Templates`.
3. Check the Wiki's Documentation: The wiki's documentation may list available infobox templates and provide instructions on how to use them.
Once you find a suitable template, simply copy and paste it into your article and replace the placeholder values with the appropriate information.
Consider the following when choosing an existing infobox:
Relevance: Does the template contain the data fields you need?
Consistency: Is the template used consistently across other articles on the wiki?
Maintainability: Is the template well-maintained and updated?
Customizing Existing Infoboxes
Sometimes, an existing infobox may not perfectly meet your needs. In this case, you can customize it by:
Adding New Parameters: You can add new parameters to the template to display additional information.
Modifying Existing Parameters: You can change the labels or data types of existing parameters.
Changing the Layout: You can adjust the layout of the infobox by rearranging the parameters or adding new sections.
However, be careful when customizing existing infoboxes, especially if they are widely used. Changes to a widely used template can affect many articles on the wiki. It's generally best to create a new template if you need to make significant changes.
Best Practices
Keep it Concise: Infoboxes should be concise and to the point. Avoid including excessive detail.
Use Standardized Labels: Use standardized labels for data fields to ensure consistency across articles.
Provide Sources: Whenever possible, cite sources for the information presented in the infobox.
Use Appropriate Images: Choose images that are relevant to the subject and of high quality.
Test Your Infobox: Before saving your article, preview the infobox to ensure it displays correctly.
Follow Wiki Guidelines: Adhere to the specific infobox guidelines established by your wiki. Many wikis have style guides that dictate how infoboxes should be used.
Accessibility: Ensure your infobox is accessible to users with disabilities. Provide alt text for images and use clear, concise language.
Common Infobox Parameters
Here's a list of common parameters used in infoboxes:
`name` or `title`: The name of the subject.
`image`: The filename of an image.
`caption`: The caption for the image.
`birthdate`: The birthdate of a person.
`deathdate`: The deathdate of a person.
`birthplace`: The place of birth.
`occupation`: The person's occupation.
`nationality`: The person's nationality.
`location`: The location of a place.
`coordinates`: The geographical coordinates of a place.
`population`: The population of a place.
`area`: The area of a place.
`founded`: The founding date of an organization.
`headquarters`: The headquarters location of an organization.
`genre`: The genre of a film, book, or game.
`director`: The director of a film.
`author`: The author of a book.
`developer`: The developer of a game.
`release_date`: The release date of a film, book, or game.
`website`: The official website of the subject.
These are just a few examples. The specific parameters you use will depend on the subject of your article and the purpose of the infobox. Understanding Fibonacci retracement levels can be similar to understanding the parameters within an infobox – both involve identifying key elements and their relationships.

Template:Infobox – A Beginner's Guide
This article provides a comprehensive introduction to the `Template:Infobox` tag in MediaWiki, specifically geared towards users new to wiki editing. Infoboxes are a crucial part of a well-structured and informative wiki, offering a concise summary of key facts about a topic. We will cover what infoboxes are, why they're useful, how to use them, common parameters, customization, troubleshooting, and best practices. This guide is written for MediaWiki 1.40.
What is an Infobox?
An infobox (short for "information box") is a standardized template used to present a summary of vital information about a subject in a consistent and visually appealing format. Typically located in the top-right corner of a wiki page, the infobox acts as a quick reference guide for readers. Think of it as a snapshot of the most important details. Unlike free-form text within the article body, infoboxes are structured, using predefined fields (parameters) to display data. This standardization aids readability and allows for easy comparison between different topics. For example, an infobox for a country might include fields for population, capital, official language, and area. An infobox for a stock might include fields for ticker symbol, company name, industry, and current price. The aim is to present essential information in a concise, easily digestible manner. Understanding Help:Templates is fundamental to understanding infoboxes; they *are* templates.
Why Use Infoboxes?
Infoboxes offer several significant advantages:
**Improved Readability:** A well-formatted infobox allows readers to quickly grasp the core details of a topic without having to scan through large blocks of text.
**Consistency:** Using templates ensures consistent presentation across all articles, making the wiki more professional and user-friendly. This consistency helps readers navigate and understand the information presented. Compare this to the chaotic appearance of articles without consistent formatting.
**Data Summarization:** Infoboxes condense complex information into a manageable format, highlighting key facts.
**Navigation:** Infoboxes often contain links to related articles, enhancing navigation within the wiki.
**Data Mining & Automated Processing:** The structured data within infoboxes can be used for automated tasks such as generating lists, reports, and other derived content. This is particularly useful for large wikis with extensive databases of information.
**Visual Appeal:** Infoboxes break up the monotony of text and add visual interest to a page.
How to Use an Infobox: A Step-by-Step Guide
1. **Find an Existing Infobox Template:** Before creating a new infobox, check if one already exists for your topic. Browse the Special:Templates page to search for relevant templates. For example, if you're writing about a chemical compound, search for "Infobox chemical." Using an existing template is *always* preferred, as it ensures consistency and reduces maintenance.
2. **Include the Template in Your Article:** Once you've found a suitable template, include it in your article using the following syntax:
Replace "Infobox Chemical" with the actual name of the template. This will insert the basic structure of the infobox into your article.
3. **Populate the Parameters:** Infobox templates have predefined parameters (fields) that you need to fill in with specific data. The documentation for each template will list these parameters and explain their purpose. You can find the documentation by clicking the "What links here" link on the template's page (e.g., Special:WhatLinksHere/Template:Infobox Chemical). Parameters are typically specified as `parameter_name = parameter_value`. For example:
```wiki
{{Infobox Chemical
name = Water
formula = H₂O
molar_mass = 18.015 g/mol
density = 1.00 g/cm³
}}
```
4. **Preview and Edit:** Always preview your changes before saving the article. This allows you to check that the infobox is displaying correctly and that all the data is accurate. Edit the parameters as needed to refine the appearance and content of the infobox.
Common Infobox Parameters
While the specific parameters vary depending on the template, some common ones include:
**name:** The primary name of the subject.
**image:** The name of an image file to display in the infobox. Use `image = Example.jpg`.
**caption:** A caption for the image.
**alt:** Alternative text for the image (for accessibility).
**label1/data1, label2/data2, etc.:** Generic parameters for adding custom labels and data. These are useful when a template doesn't have a specific parameter for a particular piece of information.
**unit1, unit2, etc.:** Units associated with the data values.
**link1, link2, etc.:** Links associated with the data values.
**color:** Background color of the infobox (use cautiously).
**above:** Text that appears above the main content of the infobox.
**below:** Text that appears below the main content of the infobox.
The specific parameters and their usage are *always* documented on the template's page. Refer to that documentation for accurate information.
Customizing Infoboxes
While using existing templates is recommended, you may sometimes need to customize them to suit your specific needs. There are several ways to do this:
**Using Generic Parameters:** As mentioned earlier, `label1/data1`, `label2/data2`, etc., allow you to add custom fields without modifying the template itself.
**Creating New Templates:** If you need significant customization, you can create a new infobox template. This requires a good understanding of MediaWiki template syntax and is best left to experienced users. See Help:Creating templates for more information.
**Modifying Existing Templates (with Caution):** If you have the necessary permissions, you can modify existing templates. However, this should be done with extreme caution, as changes to templates can affect many articles. Always discuss significant changes with other editors before implementing them. Consider creating a sub-template for customization instead of directly altering the main template. This allows for easier rollback if necessary.
**Using Conditional Statements:** You can use conditional statements (e.g., `#if`, `#ifeq`) within templates to display different content based on the values of certain parameters. This allows for greater flexibility and adaptability.
Troubleshooting Infobox Issues
Here are some common problems you might encounter when working with infoboxes and how to fix them:
**Infobox Not Displaying:** Ensure you've included the template correctly using the `Template:Template Name` syntax. Check for typos in the template name. Make sure the template exists.
**Incorrect Data Displaying:** Double-check the parameter values you've entered. Ensure you're using the correct units and formatting. Consult the template documentation for guidance.
**Image Not Displaying:** Verify that the image file exists and is uploaded to the wiki. Ensure you've entered the correct image name in the `image` parameter. Check the image's alt text.
**Infobox Formatting Issues:** Incorrect parameter usage or syntax errors can cause formatting problems. Review the template documentation and your code carefully. Use the preview function to identify and correct errors.
**Template Errors:** If a template contains errors, it may not display correctly. Check the template's page for error messages. Report the error to the template's maintainer.
Best Practices for Infoboxes
**Consistency is Key:** Use existing templates whenever possible. If you create a new template, ensure it's consistent with the style and format of other infoboxes on the wiki.
**Accuracy:** Ensure that all the data in the infobox is accurate and up-to-date. Cite your sources if necessary.
**Conciseness:** Keep the infobox concise and focused on the most important information. Avoid including unnecessary details.
**Accessibility:** Provide alternative text for images to ensure accessibility for users with visual impairments.
**Documentation:** Document your templates clearly, explaining the purpose of each parameter.
**Maintainability:** Write templates that are easy to maintain and update.
**Avoid Excessive Customization:** While customization is possible, avoid making changes that deviate significantly from the standard template format.
**Test Thoroughly:** Always test your infoboxes thoroughly before saving the article.
**Collaboration:** Discuss significant changes to templates with other editors before implementing them.
Advanced Infobox Techniques
**Template Loops:** For displaying lists of data, you can use template loops (using parser functions like `#recurse`).
**Data Structures:** Utilize data structures within templates to organize and manage complex information.
**Modules:** Leverage Lua modules to create more powerful and flexible templates. This requires advanced programming knowledge. See Help:Lua for details.
**External Data Sources:** Integrate data from external sources (e.g., databases, APIs) using extensions like Wikidata.

An infobox (short for "information box") is a standardized template used to present a summary of vital information about a subject in a consistent and visually appealing format. Typically located in the top-right corner of a wiki page, the infobox acts as a quick reference guide for readers. Think of it as a snapshot of the most important details. Unlike free-form text within the article body, infoboxes are structured, using predefined fields (parameters) to display data. This standardization aids readability and allows for easy comparison between different topics. For example, an infobox for a country might include fields for population, capital, official language, and area. An infobox for a stock might include fields for ticker symbol, company name, industry, and current price. The aim is to present essential information in a concise, easily digestible manner. Understanding Help:Templates is fundamental to understanding infoboxes; they *are* templates.
Why Use Infoboxes?
Infoboxes offer several significant advantages:
**Improved Readability:** A well-formatted infobox allows readers to quickly grasp the core details of a topic without having to scan through large blocks of text.
**Consistency:** Using templates ensures consistent presentation across all articles, making the wiki more professional and user-friendly. This consistency helps readers navigate and understand the information presented. Compare this to the chaotic appearance of articles without consistent formatting.
**Data Summarization:** Infoboxes condense complex information into a manageable format, highlighting key facts.
**Navigation:** Infoboxes often contain links to related articles, enhancing navigation within the wiki.
**Data Mining & Automated Processing:** The structured data within infoboxes can be used for automated tasks such as generating lists, reports, and other derived content. This is particularly useful for large wikis with extensive databases of information.
**Visual Appeal:** Infoboxes break up the monotony of text and add visual interest to a page.
How to Use an Infobox: A Step-by-Step Guide
1. **Find an Existing Infobox Template:** Before creating a new infobox, check if one already exists for your topic. Browse the Special:Templates page to search for relevant templates. For example, if you're writing about a chemical compound, search for "Infobox chemical." Using an existing template is *always* preferred, as it ensures consistency and reduces maintenance.
2. **Include the Template in Your Article:** Once you've found a suitable template, include it in your article using the following syntax:
Replace "Infobox Chemical" with the actual name of the template. This will insert the basic structure of the infobox into your article.
3. **Populate the Parameters:** Infobox templates have predefined parameters (fields) that you need to fill in with specific data. The documentation for each template will list these parameters and explain their purpose. You can find the documentation by clicking the "What links here" link on the template's page (e.g., Special:WhatLinksHere/Template:Infobox Chemical). Parameters are typically specified as `parameter_name = parameter_value`. For example:
```wiki
{{Infobox Chemical
name = Water
formula = H₂O
molar_mass = 18.015 g/mol
density = 1.00 g/cm³
}}
```
4. **Preview and Edit:** Always preview your changes before saving the article. This allows you to check that the infobox is displaying correctly and that all the data is accurate. Edit the parameters as needed to refine the appearance and content of the infobox.
Common Infobox Parameters
While the specific parameters vary depending on the template, some common ones include:
**name:** The primary name of the subject.
**image:** The name of an image file to display in the infobox. Use `image = Example.jpg`.
**caption:** A caption for the image.
**alt:** Alternative text for the image (for accessibility).
**label1/data1, label2/data2, etc.:** Generic parameters for adding custom labels and data. These are useful when a template doesn't have a specific parameter for a particular piece of information.
**unit1, unit2, etc.:** Units associated with the data values.
**link1, link2, etc.:** Links associated with the data values.
**color:** Background color of the infobox (use cautiously).
**above:** Text that appears above the main content of the infobox.
**below:** Text that appears below the main content of the infobox.
The specific parameters and their usage are *always* documented on the template's page. Refer to that documentation for accurate information.
Customizing Infoboxes
While using existing templates is recommended, you may sometimes need to customize them to suit your specific needs. There are several ways to do this:
**Using Generic Parameters:** As mentioned earlier, `label1/data1`, `label2/data2`, etc., allow you to add custom fields without modifying the template itself.
**Creating New Templates:** If you need significant customization, you can create a new infobox template. This requires a good understanding of MediaWiki template syntax and is best left to experienced users. See Help:Creating templates for more information.
**Modifying Existing Templates (with Caution):** If you have the necessary permissions, you can modify existing templates. However, this should be done with extreme caution, as changes to templates can affect many articles. Always discuss significant changes with other editors before implementing them. Consider creating a sub-template for customization instead of directly altering the main template. This allows for easier rollback if necessary.
**Using Conditional Statements:** You can use conditional statements (e.g., `#if`, `#ifeq`) within templates to display different content based on the values of certain parameters. This allows for greater flexibility and adaptability.
Troubleshooting Infobox Issues
Here are some common problems you might encounter when working with infoboxes and how to fix them:
**Infobox Not Displaying:** Ensure you've included the template correctly using the `Template:Template Name` syntax. Check for typos in the template name. Make sure the template exists.
**Incorrect Data Displaying:** Double-check the parameter values you've entered. Ensure you're using the correct units and formatting. Consult the template documentation for guidance.
**Image Not Displaying:** Verify that the image file exists and is uploaded to the wiki. Ensure you've entered the correct image name in the `image` parameter. Check the image's alt text.
**Infobox Formatting Issues:** Incorrect parameter usage or syntax errors can cause formatting problems. Review the template documentation and your code carefully. Use the preview function to identify and correct errors.
**Template Errors:** If a template contains errors, it may not display correctly. Check the template's page for error messages. Report the error to the template's maintainer.
Best Practices for Infoboxes
**Consistency is Key:** Use existing templates whenever possible. If you create a new template, ensure it's consistent with the style and format of other infoboxes on the wiki.
**Accuracy:** Ensure that all the data in the infobox is accurate and up-to-date. Cite your sources if necessary.
**Conciseness:** Keep the infobox concise and focused on the most important information. Avoid including unnecessary details.
**Accessibility:** Provide alternative text for images to ensure accessibility for users with visual impairments.
**Documentation:** Document your templates clearly, explaining the purpose of each parameter.
**Maintainability:** Write templates that are easy to maintain and update.
**Avoid Excessive Customization:** While customization is possible, avoid making changes that deviate significantly from the standard template format.
**Test Thoroughly:** Always test your infoboxes thoroughly before saving the article.
**Collaboration:** Discuss significant changes to templates with other editors before implementing them.
Advanced Infobox Techniques
**Template Loops:** For displaying lists of data, you can use template loops (using parser functions like `#recurse`).
**Data Structures:** Utilize data structures within templates to organize and manage complex information.
**Modules:** Leverage Lua modules to create more powerful and flexible templates. This requires advanced programming knowledge. See Help:Lua for details.
**External Data Sources:** Integrate data from external sources (e.g., databases, APIs) using extensions like Wikidata.

Advanced Transclusion Techniques
Recursive Transclusion: While possible, recursive transclusion (a template transcluding itself, directly or indirectly) can lead to infinite loops and should be avoided. MediaWiki has safeguards to prevent this, but it's still best practice to avoid creating such structures.
Parser Functions: Beyond `#ifexist` and `#safesize`, MediaWiki offers a wide range of parser functions that can be used within transclusions to manipulate text, perform calculations, and create dynamic content. These include functions for string manipulation, date formatting, and mathematical operations.
Variables: You can define variables within templates using the `let` parser function. This allows you to store values and reuse them within the template.
Template Loops: For iterating over lists of items, you can use template loops in combination with parser functions like `{{#arraymap}}` and `{{#each}}`. This is useful for generating tables or lists dynamically.
Module Integration: For even more complex logic and functionality, you can integrate templates with Lua modules. This allows you to write code that can be called from templates, providing a much greater level of flexibility and control. Modules are particularly useful for tasks like data processing, complex calculations, and external API integration. Consider using modules to implement a Bollinger Bands calculator or to fetch real-time Forex rates.
Limitations and Considerations
Transclusion Overhead: Transclusion can add overhead to page rendering, especially when dealing with a large number of transclusions or complex templates. Excessive transclusion can slow down page load times.
Circular Dependencies: Avoid creating circular dependencies where two or more templates transclude each other in a loop. This can lead to errors and prevent the pages from rendering correctly.
Editing Conflicts: When multiple users are editing a template and pages that transclude it, there is a potential for editing conflicts. Careful coordination and communication are important.
Template Limits: MediaWiki imposes limits on the number of transclusions and the size of transcluded content to prevent performance issues. These limits can be configured by the wiki administrator.
Security Considerations: Be careful when transcluding content from untrusted sources, as it could potentially contain malicious code. Always review the content of templates and pages before transcluding them. Avoid using transclusion to include user-submitted content directly.
Maintenance: While transclusion promotes consistency, it also means that changes to a template can have widespread effects. Thorough testing and documentation are essential. Keep a record of which pages transclude specific templates for easier maintenance.
Best Practices for Transclusion
Use Templates for Reusable Content: Identify content that is used on multiple pages and create templates for it.
Document Your Templates: Clearly document the purpose of each template, the parameters it accepts, and how to use it. Use the template's talk page for documentation.
Keep Templates Simple: Avoid creating overly complex templates. Break down complex functionality into smaller, more manageable templates.
Use `` Wisely: Use `` to define the specific content that should be transcluded, minimizing unwanted content.
Test Your Templates Thoroughly: Test your templates with different parameters and in different contexts to ensure they work as expected.
Monitor Template Usage: Use tools like "What links here" to monitor which pages transclude a given template.
Consider Performance: Be mindful of the performance impact of transclusion, especially when dealing with a large number of transclusions or complex templates. Use `#safesize` to limit the size of transcluded content.
Use Categories: Categorize your templates to make them easier to find and manage. For example, you might use categories like "Templates", "Infoboxes", or "Navigation Templates".
Utilize Modules for Complex Logic: For tasks requiring advanced programming or data manipulation, leverage Lua modules for enhanced capabilities. This will improve the maintainability and performance of your wiki.
Stay Updated with MediaWiki Features: MediaWiki is constantly evolving. Stay informed about new features and best practices related to transclusion. Refer to the official MediaWiki documentation for the latest information. Explore new parser functions and template features to optimize your workflow. Consider integrating with external APIs to display real-time data, such as MACD indicators or RSI values.
