Problem Summary
"I think I know the answer but just checking in case I missed something.The code that generates "Documentation for this page" link in the footer. Is there any way to modify or remove this within a plugin? I ask as we have a number of custom plugins for which this link just goes to an invalid page (the docs wiki obviously doesn't know about our plugins). It would be nice to tidy that up.

### 🤖 الحل الهندسي المقترح:
As a Moodle expert and Linux system administrator, I understand the frustration of having broken or irrelevant links cluttering your Moodle instance, especially for custom plugins. The "Documentation for this page" link in the Moodle footer is a core feature, and while useful for standard Moodle components, it can indeed lead to invalid pages for custom developments that don't exist on the official Moodle Docs Wiki.
This Standard Operating Procedure (SOP) will guide you through the best practices for managing this link for your custom plugins, addressing both providing a correct link and entirely removing it when documentation is unavailable or undesired.
---
**SOP Title: Customizing or Removing the "Documentation for this page" Link for Moodle Plugins**
**1. Problem Description**
The "Documentation for this page" link in the Moodle footer, generated by core Moodle, attempts to link to relevant documentation on the Moodle Docs Wiki (docs.moodle.org). For custom plugins (modules, activities, blocks, local plugins, tools), Moodle's default behavior often generates a URL for which no documentation exists on the official wiki, resulting in a "Page not found" error when clicked. The goal is to either:
* Provide a custom, valid documentation URL for your plugin.
* Completely remove the link when no relevant documentation exists or is desired.
**2. Understanding Moodle's Documentation Link Generation**
Moodle uses the `$PAGE->component` variable to determine the context for the documentation link.
* If a plugin defines a `docs_url` in its `version.php` file, Moodle will prioritize this URL.
* If `docs_url` is not defined or is empty, Moodle constructs a default URL based on the component name and the configured Moodle Docs base URL (e.g., `https://docs.moodle.org/en/mod/mycustomplugin`).
**3. Solution Options**
We will cover two primary, Moodle-idiomatic solutions:
**Solution 1: Providing a Custom Documentation Link (Recommended when documentation exists)**
This method is implemented directly within your custom plugin's `version.php` file. It's the most straightforward "within a plugin" approach.
**Pros:**
* Simple to implement.
* Part of the plugin's own configuration.
* Moodle-native way to define a plugin's documentation.
**Cons:**
* Only works for *providing* a valid URL; it does **not** allow you to *remove* the link if you set `docs_url` to an empty string. Moodle will fall back to generating a generic Moodle Docs link if `docs_url` is empty.
**Steps:**
1. **Locate your plugin's `version.php` file:**
Navigate to your custom plugin's directory. For example:
* `moodle/mod/yourcustommodule/version.php`
* `moodle/blocks/yourcustomblock/version.php`
* `moodle/local/yourcustomlocalplugin/version.php`
* `moodle/tool/yourcustomtool/version.php`
2. **Edit `version.php`:**
Open the `version.php` file and add or modify the `$plugin->docs_url` variable. Set its value to the full URL of your plugin's documentation.
**Example:**
```php
<?php
defined('MOODLE_INTERNAL') || die();
$plugin->component = 'mod_yourcustommodule'; // Moodle component name
$plugin->version = 2023102600; // YYYYMMDDHH (date of last modification)
$plugin->requires = 2023100900; // Moodle 4.2.1 minimum version
$plugin->maturity = MATURITY_STABLE;
$plugin->release = '4.2.0';
// Add or modify this line to point to your custom documentation URL
$plugin->docs_url = 'https://your-company-wiki.example.com/doku.php?id=moodle:custom_plugins:yourcustommodule';
```
3. **Save the file.**
4. **Clear Moodle caches (Linux Admin Step):**
After making changes, Moodle needs to refresh its plugin information and caches.
* **Via Moodle UI:** Log in as an administrator, navigate to `Site administration > Development > Purge all caches`.
* **Via CLI (recommended for server admins):**
```bash
cd /path/to/your/moodle/install
php admin/cli/purge_caches.php
```
5. **Verify the change:**
Go to a page related to your custom plugin. The "Documentation for this page" link in the footer should now point to your specified `docs_url`.
---
**Solution 2: Removing or Conditionally Modifying the Documentation Link (Recommended for removal)**
This method involves creating or modifying a custom Moodle theme (or a child theme) to override the core Moodle renderer. This is the most robust and Moodle-idiomatic way to completely suppress the documentation link for specific custom plugins, as direct removal is not supported by the `docs_url` setting.
**Why a Theme Override?**
The "Documentation for this page" link is generated by the `get_documentation_link()` method within Moodle's `core_renderer` class. To prevent this link from appearing or to change its behavior globally or conditionally, you need to override this core rendering logic. Themes are the designated place in Moodle to customize output renderers.
**Pros:**
* Allows complete removal of the link.
* Provides granular control over the link's behavior based on the current page's component.
* Follows Moodle's extensibility model for UI customization.
**Cons:**
* Requires a custom theme or child theme.
* Slightly more complex setup than just modifying `version.php`.
**Steps:**
1. **Determine your active theme:**
Go to `Site administration > Appearance > Themes > Theme selector` to see which theme is currently active. If it's `Boost` or another standard theme, you should create a child theme to avoid modifying core theme files directly (which would be overwritten on updates). If you already have a custom theme, you can modify it directly.
2. **Create a Child Theme (if not already using a custom theme):**
If your active theme is, for example, `Boost`:
* **Linux Admin Step: Create the child theme directory:**
```bash
cd /path/to/your/moodle/install/theme
mkdir mychildtheme # Choose a meaningful name
chown -R www-data:www-data mychildtheme # Adjust user/group as per your web server setup
chmod -R 0755 mychildtheme
```
* **Create `theme/mychildtheme/config.php`:**
```php
<?php
defined('MOODLE_INTERNAL') || die();
$THEME->name = 'mychildtheme';
$THEME->parent = 'boost'; // Replace 'boost' with your parent theme's name
$THEME->version = 2023102600; // Update this to current date YYYYMMDDHH
$THEME->requires = 2023100900; // Minimum Moodle version this theme requires (e.g., for Moodle 4.2.1)
// Register your custom renderer to override core_renderer
$THEME->rendererfactory = 'theme_overridden_renderer_factory';
$THEME->rendererclasses = [
'core' => 'theme_mychildtheme_core_renderer', // Class name defined in renderers.php
];
```
3. **Create `theme/mychildtheme/renderers.php` (or modify existing custom theme's `renderers.php`):**
This file will contain the custom renderer class that extends Moodle's `core_renderer`.
```php
<?php
defined('MOODLE_INTERNAL') || die();
/**
* Custom renderer class for mychildtheme.
* Overrides core_renderer methods.
*/
class theme_mychildtheme_core_renderer extends core_renderer {
/**
* Get the documentation link for the current page.
*
* @return string HTML for the documentation link, or empty string if none.
*/
public function get_documentation_link(): string {
global $PAGE;
// Define an array of custom plugin components for which to disable the link.
// Add the 'component' identifier of your custom plugins here.
// Examples: 'mod_mycustommodule', 'tool_mycustomtool', 'block_mycustomblock', 'local_mycustomlocalplugin'
$plugins_to_disable_docs = [
'mod_yourcustommodule_a',
'tool_yourcustomtool_b',
'block_yourcustomblock_c',
'local_yourcustomlocalplugin_d',
// Add more custom components here as needed.
];
// Check if the current page's component is in our disable list.
if (in_array($PAGE->component, $plugins_to_disable_docs)) {
return ''; // Return an empty string to remove the link.
}
// If not in the disable list, call the parent method to generate the default link.
// This ensures that documentation links for other Moodle components (core, standard plugins)
// will still function normally.
return parent::get_documentation_link();
}
}
```
**Important:** Replace `'mod_yourcustommodule_a'`, etc., with the actual component names of your custom plugins. You can find a plugin's component name in its `version.php` file (e.g., `$plugin->component = 'mod_yourcustommodule';`).
4. **Save `renderers.php`.**
5. **Activate the Child Theme (if applicable):**
If you created a new child theme:
* Log in to Moodle as an administrator.
* Go to `Site administration > Appearance > Themes > Theme selector`.
* Click "Change theme" for the "Default" setting.
* Select your new `mychildtheme` and click "Use theme".
6. **Clear Moodle caches (Linux Admin Step):**
This is crucial for Moodle to recognize the new theme and renderer overrides.
* **Via Moodle UI:** Log in as an administrator, navigate to `Site administration > Development > Purge all caches`.
* **Via CLI (recommended for server admins):**
```bash
cd /path/to/your/moodle/install
php admin/cli/purge_caches.php
```
7. **Verify the change:**
Go to a page related to one of the custom plugins you listed in `$plugins_to_disable_docs`. The "Documentation for this page" link should now be completely absent from the footer for that page. For other Moodle pages not in your disable list, the link should appear as usual.
**4. Linux System Administrator Deployment and Maintenance**
* **File Permissions:** Ensure that Moodle can read the new theme/plugin files.
```bash
chown -R www-data:www-data /path/to/your/moodle/install/theme/mychildtheme
chmod -R 0755 /path/to/your/moodle/install/theme/mychildtheme
```
(Adjust `www-data:www-data` to your web server's user and group, e.g., `apache:apache` for RHEL/CentOS, `nginx:nginx` for Nginx on some systems).
* **Version Control:** If your Moodle instance is under version control (e.g., Git), commit these changes to your repository. This ensures that your customizations are preserved and can be deployed consistently across environments.
* **Testing:** Always test changes in a development or staging environment before deploying to production.
* **Moodle Updates:** When upgrading Moodle, always review your custom theme's `config.php` and `renderers.php` to ensure compatibility with new Moodle versions. The core `get_documentation_link()` method might change, requiring updates to your override.
By following these procedures, you can effectively manage the "Documentation for this page" link for your custom Moodle plugins, enhancing the user experience by providing relevant documentation or removing misleading links."
