Ever wondered how you can make your WordPress site do exactly what you want when a specific action occurs? Let me introduce you to the admin_post_nopriv_action hook. This is a powerful tool in the WordPress development arsenal, allowing you to execute custom code when a certain action is triggered, even for non-logged-in users. We’ll explore how to use this hook with some live examples. Let’s dive in!

Live Example 1: Basic Hook Usage

Here’s a simple example of how to use the admin_post_nopriv_action hook. First, we define a function and then register it using add_action.

    function weplugins_execute_on_admin_post_nopriv_action_event() {
        // Code to be executed when the action occurs.
    }
    // add the action
    add_action( "admin_post_nopriv_action", "weplugins_execute_on_admin_post_nopriv_action_event");
    

Live Example 2: Removing the Hook

Sometimes, you might want to remove a registered hook. You can do this using remove_action. Here’s how you can remove the hook we registered earlier.

    remove_action( "admin_post_nopriv_action", "weplugins_execute_on_admin_post_nopriv_action_event");
    

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

Live Example 3: Dynamic Hook Usage

With dynamic hooks, you can execute different actions based on the $action parameter. Here’s how you can use it.

    $action = 'custom_action'; // Replace with your action
    do_action( "admin_post_nopriv_{$action}" );
