How to use network_admin_url filter in WordPress

Example 1: Basic URL Modification

Here’s a straightforward example to get you started. We define a function weplugins_modify_network_admin_url_defaults which takes three parameters. This function is then registered using add_filter.

    function weplugins_modify_network_admin_url_defaults($url, $path, $scheme) { 
        // Update the $url variable according to your website requirements and return this variable.
        return $url; 
    }
    // add the filter
    add_filter( "network_admin_url", "weplugins_modify_network_admin_url_defaults", 10, 3 );
    

Example 2: Conditional URL Modification

Want to modify the URL conditionally? No problem! Here’s how you can tweak the URL based on certain conditions.

    function weplugins_conditional_network_admin_url($url, $path, $scheme) { 
        if ($path === 'special-path') {
            $url = 'https://your-custom-domain.com/' . $path;
        }
        return $url; 
    }
    add_filter( "network_admin_url", "weplugins_conditional_network_admin_url", 10, 3 );
    

Example 3: Removing the Filter

Sometimes you need to backtrack and remove a filter. Here’s how you can remove the callback from the hook.

    remove_filter( "network_admin_url", "weplugins_modify_network_admin_url_defaults", 10, 3 );
    

Ensure you provide the same callback function name, priority, and number of arguments while removing the hook callback.
