How to use add_link action in WordPress

So, you’re working with WordPress and you’ve come across the add_link action. This hook fires after a link is added to the database. It’s a pretty handy tool if you need to run custom code right after a link is created. Let’s dive into how you can use this hook effectively.

To get started with the add_link action, you’ll need to register it using add_action. You can place this code in your theme’s functions.php file or, better yet, in a custom WordPress Plugin. We at WePlugins prefer creating a custom plugin to keep everything intact during theme updates. Here’s how you can set it up.

Example 1: Execute on Link Addition

In this example, we define a function weplugins_execute_on_add_link_event which takes 1 parameter. We register it using add_action. The first parameter add_link is the name of the hook, the second parameter is the function name, the third is the priority, and the last is the number of arguments.

    function weplugins_execute_on_add_link_event($link_id){
       // Code to execute when a link is added
    }
    // add the action
    add_action( "add_link", "weplugins_execute_on_add_link_event" , 10, 1);
    

Example 2: Removing a Hook

Sometimes, you might need to remove a registered hook. You can use remove_action to remove the add_link action. Ensure you provide the same callback function name, priority, and number of arguments while removing the hook.

    remove_action( "add_link", "weplugins_execute_on_add_link_event", 10, 1 );
    

Example 3: Using Parameters

The add_link hook requires one parameter: $link_id, which is the ID of the link that was added. Here’s how you can utilize this parameter within your function.

    function weplugins_use_link_id($link_id){
       // Use the $link_id to perform actions
    }
    add_action( "add_link", "weplugins_use_link_id" , 10, 1);
