How to use pre_delete_term action in WordPress

Example 1: Basic Usage of pre_delete_term

Here’s how you can use the pre_delete_term hook to execute custom functionality when a term is deleted. This example shows how to set up the action and define a function that receives the term ID and taxonomy name.

    function weplugins_execute_on_pre_delete_term_event($term, $taxonomy){
        // Custom code to handle term deletion
    }
    add_action("pre_delete_term", "weplugins_execute_on_pre_delete_term_event", 10, 2);
    

Example 2: Removing a Hook Callback

Sometimes, you may need to remove a previously registered hook. Use the remove_action function to do this. Remember to provide the same callback function name, priority, and number of arguments.

    remove_action("pre_delete_term", "weplugins_execute_on_pre_delete_term_event", 10, 2);
    

Example 3: Advanced Customization

For more advanced use cases, you might want to add additional logic within the function. You can use the parameters received in the function arguments to implement custom functionality according to your website requirements.

    function weplugins_advanced_pre_delete_term_event($term, $taxonomy){
        // Implement your advanced logic here
    }
    add_action("pre_delete_term", "weplugins_advanced_pre_delete_term_event", 10, 2);
