How to use add_link_category_form_pre action in WordPress

Alright, let’s dive into the add_link_category_form_pre action. This hook fires before the link category form. As an Indian developer, I always prefer simplicity and efficiency, so here’s how you can make the most out of this hook.

To use add_link_category_form_pre action, you need to register it using add_action. You can add this code into the functions.php of your activated theme or create a custom WordPress Plugin. At WePlugins, we always recommend creating a custom WordPress Plugin to ensure your customizations remain intact even after theme updates.

In the example below, we define a function weplugins_execute_on_add_link_category_form_pre_event which takes one parameter. We then register this function using add_action. The first parameter add_link_category_form_pre is the name of the hook. The second parameter weplugins_execute_on_add_link_category_form_pre_event is the function to be called. The third parameter is the priority, and the last parameter is the number of arguments to be passed to the registered function.

Sometimes, you may need to remove a registered hook. You can use remove_action to remove the add_link_category_form_pre action.

Parameters

Below is the required parameter to use this hook:

• $arg: (object) Arguments cast to an object.

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

	function weplugins_execute_on_add_link_category_form_pre_event($arg) {
		// 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.
	}
	// Add the action
	add_action("add_link_category_form_pre", "weplugins_execute_on_add_link_category_form_pre_event", 10, 1);

To remove a hook callback, use the example below:

	remove_action("add_link_category_form_pre", "weplugins_execute_on_add_link_category_form_pre_event", 10, 1);
	

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

Using a custom plugin to handle the hook:

	/*
	Plugin Name: Custom Link Category Hook

	Version: 1.0
	Author: WePlugins
	*/

	function weplugins_custom_link_category_hook($arg) {
		// Custom code here
	}

	add_action("add_link_category_form_pre", "weplugins_custom_link_category_hook", 10, 1);
