How to use edit_category_form action in WordPress

Are you diving into the world of WordPress hooks? If so, you’re in for a treat! Hooks are a powerful way to interact with WordPress and modify its behavior without altering the core files. Today, let’s chat about the edit_category_form action hook, which fires at the end of the Edit Category form. This is a handy hook to know if you’re looking to add some custom functionality to your category editing process.

To use the edit_category_form action, you’ll first need to register it using add_action. While you can write this code into the functions.php of your activated theme, we at WePlugins recommend creating a custom WordPress Plugin. This way, nothing breaks when you update your WordPress Theme in the future. Now, let’s dive into some live examples!

Example 1: Adding a Custom Message

Here, we add a custom message to the Edit Category form. This is a great way to provide extra information to users editing categories.

    function weplugins_add_custom_message($arg) {
        echo '<p>Custom message for category editing.</p>';
    }
    add_action("edit_category_form", "weplugins_add_custom_message", 10, 1);
    

Example 2: Adding a Custom Field

In this example, we insert a custom field into the Edit Category form. This can be useful for capturing additional data related to the category.

    function weplugins_add_custom_field($arg) {
        echo '<input type="text" name="custom_field" placeholder="Enter custom data" />';
    }
    add_action("edit_category_form", "weplugins_add_custom_field", 10, 1);
    

Example 3: Modifying Existing Fields

Here, we modify an existing field in the Edit Category form. This could be used to change the default behavior or appearance of form elements.

    function weplugins_modify_existing_field($arg) {
        // Modify existing form fields here
    }
    add_action("edit_category_form", "weplugins_modify_existing_field", 10, 1);
    

Sometimes, you might need to remove a registered hook. You can use remove_action to remove the edit_category_form action if needed. Here’s how you can do that:

    remove_action("edit_category_form", "weplugins_add_custom_message", 10, 1);
    

Note: Always use the same callback function name, priority, and number of arguments when removing the hook callback.
