How to use ms_user_list_site_class filter in WordPress

Now, before we get our hands dirty with some code, remember that to use the ms_user_list_site_class filter, you first need to register it using add_filter. You can pop this code into your theme’s functions.php file or, even better, create a custom WordPress plugin. We at WePlugins always recommend using a plugin for hooks to keep things smooth when you update your theme.

Example 1: Basic Usage

Here’s a basic example of how to use the ms_user_list_site_class filter. We’ve defined a function weplugins_modify_ms_user_list_site_class_defaults with four parameters. It’s registered with add_filter.

    function weplugins_modify_ms_user_list_site_class_defaults($site_classes, $site_id, $network_id, $user) { 
        // Update the $site_classes variable according to your website requirements and return this variable. You can modify the $site_classes variable conditionally too if you want.
        return $site_classes; 
    }
    // add the filter
    add_filter( "ms_user_list_site_class", "weplugins_modify_ms_user_list_site_class_defaults", 10, 4 );
    

Example 2: Removing a Hook Callback

Sometimes, you might need to remove a registered hook. You can do this using remove_filter. Just make sure to provide the same callback function name, priority, and number of arguments.

    remove_filter( "ms_user_list_site_class", "weplugins_modify_ms_user_list_site_class_defaults", 10, 4 );
    

Example 3: Advanced Conditional Logic

Let’s say you want to add some conditional logic to modify the class names based on specific user roles or site IDs. This example shows how you can do that.

    function weplugins_advanced_modify_ms_user_list_site_class($site_classes, $site_id, $network_id, $user) {
        if($user->has_cap('manage_options')) {
            $site_classes[] = 'super-admin';
        }
        return $site_classes;
    }
    add_filter( "ms_user_list_site_class", "weplugins_advanced_modify_ms_user_list_site_class", 10, 4 );
