How to use edit_link_category_form_fields action in WordPress

So, you’ve stumbled upon the edit_link_category_form_fields action hook in WordPress, and you’re curious about how it works? No worries, I’ve got you covered! This hook fires after the Edit Link Category form fields are displayed. It’s like a backstage pass to WordPress, where you can add your own custom functionality without messing up the core files.

To get started, you’ll need to register this hook using add_action. You can place this code in the functions.php of your active theme or, even better, in a custom WordPress Plugin. We at WePlugins always recommend creating a custom plugin for hooks to ensure nothing breaks when updating your WordPress theme.

Let’s dive into some live examples to see how this hook can be used effectively!

Example 1: Basic Hook Registration

Here’s a simple example of how you can register the edit_link_category_form_fields action and execute your custom function when the action is triggered.

    function weplugins_execute_on_edit_link_category_form_fields_event($tag){
       // Your custom code here.
    }
    // add the action
    add_action("edit_link_category_form_fields", "weplugins_execute_on_edit_link_category_form_fields_event", 10, 1);
    

Example 2: Modifying Link Category Fields

In this example, we’ll modify the link category fields by adding a custom input field using the hook.

    function weplugins_add_custom_field_to_link_category($tag){
       echo '<tr class="form-field"><th scope="row" valign="top"><label for="custom_field">Custom Field</label></th><td><input type="text" name="custom_field" id="custom_field" value="" /></td></tr>';
    }
    add_action("edit_link_category_form_fields", "weplugins_add_custom_field_to_link_category", 10, 1);
    

Example 3: Removing a Hook

Sometimes, you might need to remove a registered hook. Here’s how you can do that:

    remove_action("edit_link_category_form_fields", "weplugins_execute_on_edit_link_category_form_fields_event", 10, 1);
    

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