How to use edit_terms action in WordPress

edit_terms action

Fires immediately before the given terms are edited.

To use edit_terms 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_terms_event which takes 2 parameters and we registered using add_action. The first parameter edit_terms is the name of the hook, the second parameter execute_on_edit_terms_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_terms action.

Parameters

Below are the 2 parameters required to use this hook.

• $term_id : (int) Term ID.
• $taxonomy : (string) Taxonomy slug.

Live Examples

Example 1: Do Something Before Update

Here, we demonstrate how you can use the edit_terms action to perform an operation before the term is updated.

add_action('edit_terms', 'weplugins_do_something_or_stop_update', 10, 2); 
function weplugins_do_something_or_stop_update($term_id, $taxonomy) {
    // Do something before update OR
    // Redirect back to the edit page to disable updates (remember to exit)
}

Example 2: Execute Custom Function on Term Edit

This example shows how to execute a custom function when the terms are edited in WordPress.

function weplugins_execute_on_edit_terms_event($term_id, $taxonomy) {
    // 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_terms', 'weplugins_execute_on_edit_terms_event', 10, 2);

Example 3: Remove Hook Callback

To remove a hook callback, use the example below.

remove_action('edit_terms', 'weplugins_execute_on_edit_terms_event', 10, 2);

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