How to use all_admin_notices action in WordPress

all_admin_notices action

Prints generic admin screen notices.

To use the all_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 weplugins_execute_on_all_admin_notices_event and registered it using add_action. The first parameter all_admin_notices is the name of the hook, the second parameter weplugins_execute_on_all_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 the all_admin_notices action.

Parameters

Live Example 1: Basic Usage

Below is an example of how you can use this hook.

        function weplugins_execute_on_all_admin_notices_event(){

        }
        // Add the action
        add_action("all_admin_notices", "weplugins_execute_on_all_admin_notices_event");
    

Live Example 2: Removing a Hook Callback

To remove a hook callback, use the example below.

        remove_action("all_admin_notices", "weplugins_execute_on_all_admin_notices_event");
    

Please make sure to provide the same callback function name, priority, and number of arguments while removing the hook callback.

Live Example 3: Custom Notice Message

Here’s an example of displaying a custom admin notice.

        function weplugins_custom_admin_notice(){
            echo '<div class="notice notice-info is-dismissible">
                    <p>This is a custom admin notice from WePlugins!</p>
                  </div>';
        }
        add_action( 'all_admin_notices', 'weplugins_custom_admin_notice' );
