How to use edit_taxonomy action in WordPress

The dynamic portion of the hook name, $taxonomy, refers to the taxonomy slug.

To use edit_taxonomy action, first you have to register it using add_action. You can write this code into functions.php of your activated theme or in a custom WordPress Plugin.

We at WePlugins, 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 below live example, we have defined a function execute_on_edit_taxonomy_event which takes 2 parameters and we registered using add_action. The first parameter edit_taxonomy is the name of the hook, The second parameter execute_on_edit_taxonomy_event is the name of the function which 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 in the registered function.

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

Parameters

Below are the 2 parameters required to use this hook.

do_action( "edit_{$taxonomy}", int $term_id, int $tt_id )

Below is an example of how you can use this hook.

        function weplugins_execute_on_edit_taxonomy_event($term_id, $tt_id){
           //You can write code here to be executed when this action occurs in WordPress. Use the parameters received in the function arguments & implement the required additional custom functionality according to your website requirements.
        }
        // add the action
        add_action( "edit_taxonomy", "weplugins_execute_on_edit_taxonomy_event" , 10, 2);
    

To remove a hook callback, use the example below.

remove_action( "edit_taxonomy", "weplugins_execute_on_edit_taxonomy_event", 10, 2 );

Please make sure to provide the same callback function name, priority, and number of arguments while removing the hook callback.

This example demonstrates how to log edits made to taxonomy terms.

        function weplugins_log_taxonomy_edit($term_id, $tt_id) {
            error_log("Taxonomy with Term ID {$term_id} and Taxonomy Term ID {$tt_id} was edited.");
        }
        add_action( "edit_taxonomy", "weplugins_log_taxonomy_edit", 10, 2 );
    

Automatically update a term meta field when a taxonomy term is edited.

        function weplugins_update_term_meta($term_id, $tt_id) {
            update_term_meta($term_id, 'last_edited', current_time('mysql'));
        }
        add_action( "edit_taxonomy", "weplugins_update_term_meta", 10, 2 );
    

Send an email notification whenever a taxonomy term is edited.

        function weplugins_notify_on_term_edit($term_id, $tt_id) {
            $term = get_term($term_id);
            wp_mail('admin@example.com', 'Term Edited', "The term {$term->name} was edited.");
        }
        add_action( "edit_taxonomy", "weplugins_notify_on_term_edit", 10, 2 );
