How to use network_admin_notices action in WordPress

network_admin_notices action

Prints network admin screen notices.

To use network_admin_notices action, first, you have to register it using add_action. You can write this code into functions.php of your activated theme or in a custom WordPress Plugin.

We at WePlugins always prefer to create a custom WordPress Plugin while using hooks so nothing breaks when you update your WordPress Theme in the future.

In the below live example, we have defined a function execute_on_network_admin_notices_event and we registered it using add_action. The first parameter network_admin_notices is the name of the hook, the second parameter execute_on_network_admin_notices_event is the name of the function which needs to be called, the third parameter is the priority of calling the hook if the same hook is used multiple times, and the last parameter is the number of arguments (if any) to be passed in the registered function.

Sometimes, you have to remove a registered hook so you can use remove_action to remove network_admin_notices action.

    }
    

Live Example 2: Execute a Function on Network Admin Notices

Below is an example of how you can use this hook to execute custom code when the network admin notices action occurs.

    }
    // add the action
    add_action( 'network_admin_notices', 'weplugins_execute_on_network_admin_notices_event' );
    

Live Example 3: Remove a Hook Callback
