    The activate_sitewide_plugin() function in WordPress is a part of its Multisite feature, which allows you to manage multiple WordPress sites from a single installation.

    Function:

    activate_sitewide_plugin()

    Deprecated Functionality:

    This function was used for activating a network-only plugin across all sites in a WordPress Multisite network. However, it's important to note that activate_sitewide_plugin() has been deprecated. This means it is no longer recommended for use in newer WordPress versions, as it may be removed in future updates and can lead to compatibility issues.

    Description:

    • Purpose: The primary use of this function was to activate a specific plugin across all sites within a WordPress Multisite network.
    • How It Worked: When invoked, it would ensure that the specified plugin was activated on each site within the network, not just the site where the activation was initiated.

    See Also:

    • activate_plugin(): This is an alternative function that's used for activating plugins in WordPress. Unlike activate_sitewide_plugin(), activate_plugin() is used for activating a plugin on a single site, whether in a Multisite network or a standard WordPress installation.

    Sample Usage (Historical Context):

    Let's assume you wanted to activate a plugin called example-plugin/example-plugin.php across all sites in your network. The usage of activate_sitewide_plugin() would have looked something like this:

    if ( function_exists( 'activate_sitewide_plugin' ) ) {
        activate_sitewide_plugin( 'example-plugin/example-plugin.php' );
    }
    

    This code checks if activate_sitewide_plugin() exists to prevent errors in case of its removal in newer WordPress versions. Then it activates example-plugin/example-plugin.php across the entire network.

    Important Notes:

    • Deprecated Status: Since activate_sitewide_plugin() is deprecated, it's crucial to use current alternatives for similar functionality.
    • Current Alternatives: For activating plugins network-wide in a Multisite setup, you should explore current methods in the WordPress Codex or Developer Resources.
    • Future Proofing: Always ensure compatibility with the latest WordPress version to maintain security and functionality of your site.

    For the most current practices and functions, always refer to the official WordPress documentation.
