How to use deprecated_constructor_run action in WordPress

In the world of WordPress development, hooks are like magic spells that let you customize your website without touching the core files. Today, we’re diving into the deprecated_constructor_run action hook, which comes into play when a deprecated constructor is called. Let’s explore how you can use it in your projects.

To use the deprecated_constructor_run action, first, you have to register it using add_action. You can write this code into the functions.php file of your activated theme or in a custom WordPress Plugin. At WePlugins, we 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 example below, we define a function execute_on_deprecated_constructor_run_event which takes three parameters, and we register it using add_action. The first parameter deprecated_constructor_run is the name of the hook, the second parameter execute_on_deprecated_constructor_run_event is the name of the function that 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 to the registered function.

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

Example 1: Basic Hook Registration

This example demonstrates a basic registration of the deprecated_constructor_run hook.

    function weplugins_execute_on_deprecated_constructor_run_event($class, $version, $parent_class){
       // Custom functionality when the action occurs
    }
    // Add the action
    add_action( "deprecated_constructor_run", "weplugins_execute_on_deprecated_constructor_run_event", 10, 3);
    

Example 2: Removing a Hook

This example shows how to remove the previously registered hook.

    // Remove the action
    remove_action( "deprecated_constructor_run", "weplugins_execute_on_deprecated_constructor_run_event", 10, 3 );
    

Example 3: Advanced Usage

In this example, we handle additional logic within the function triggered by the hook.

    function weplugins_advanced_deprecated_constructor_event($class, $version, $parent_class){
       if($version < '5.0.0'){
           // Handle logic for versions below 5.0.0
       }
    }
    // Add the action with advanced logic
    add_action( "deprecated_constructor_run", "weplugins_advanced_deprecated_constructor_event", 10, 3);
    

Parameters

• $class: (string) The class containing the deprecated constructor.
• $version: (string) The version of WordPress that deprecated the function.
• $parent_class: (string) The parent class calling the deprecated constructor.
