The Admin Footer display is the default and most popular way to view your site's version information at a glance.

# Admin Footer

The Admin Footer integration is the core feature of Version Info. It replaces the default WordPress footer text with a clean, informative line showing your site's technical stack.

### What It Displays

The admin footer shows the following information on every WP-Admin page:

*   **WordPress version** (with a one-click update link if an update is available)
*   **PHP version**
*   **MySQL version**
*   **Web Server** software (e.g., Apache, Nginx, LiteSpeed)

### Enabling / Disabling

The Admin Footer display is **enabled by default** upon activation. To toggle it:

1.  Navigate to **Settings > Version Info > General**.
2.  Check or uncheck **Show in Admin Footer**.
3.  Click **Save Changes**.

When a WordPress core update is available, Version Info automatically appends an "Update available" link next to the current WordPress version, linking directly to the **Dashboard > Updates** page.

### How It Works

Version Info hooks into the `admin_footer_text` WordPress filter to replace the default footer content. The version string is assembled from core WordPress functions and PHP's built-in constants, ensuring accuracy without any external API calls.

### Customizing the Output

Developers can modify the footer output using the `version_info_footer_details` filter:

`add_filter( 'version_info_footer_details', 'customize_footer_output' );  function customize_footer_output( string $footer_text ): string {     // Append custom text to the version info footer     $footer_text .= ' | Custom Server ID: ' . gethostname();     return $footer_text; }`
