How to use activate_blog action in WordPress

As an Indian developer diving into the world of WordPress hooks, you’re bound to come across the activate_blog action. This hook is quite handy as it fires up whenever a network site is activated. Now, let’s break it down and see how we can make the most of this hook in our WordPress projects. Remember, it’s often a good idea to create a custom WordPress Plugin for deploying hooks so that your theme updates won’t create havoc.

Example 1: Activate Blog Event Hook

Here’s how you can register and use the activate_blog action hook. You can plop this snippet into your theme’s functions.php file or, as I recommend, in a custom plugin.

    function weplugins_execute_on_activate_blog_event($id) {
        // Code to execute when the blog is activated
    }
    add_action("activate_blog", "weplugins_execute_on_activate_blog_event", 10, 1);
    

Example 2: Removing the Hook

Sometimes, you may need to remove a previously registered hook. The remove_action function can help you with that. Just ensure you pass the same callback function name, priority, and number of arguments.

    remove_action("activate_blog", "weplugins_execute_on_activate_blog_event", 10, 1);
    

Example 3: Custom Functionality on Activation

Use this example to add custom functionality when a network site is activated. You can modify the function to suit your specific requirements.

    function weplugins_custom_activation_function($id) {
        // Custom code for site activation
    }
    add_action("activate_blog", "weplugins_custom_activation_function", 10, 1);
