Hooks.php

A simple PHP Hooks system for registering hookable events, adding callbacks to registered events, and running callback associated with registered events.

Usage

You can use the Hooks class directly or by using some of the helper functions in helper.php

Using Directly

Step 1. Add Hookable Event

// Method 1
Hooks::getInstance()->add_hookable_event('header');
// Method 2
$hooks = Hooks::getInstance();
$hooks->add_hookable_event('header');

Step 2. Add some callbacks to the event

// Method 1
Hooks::getInstance()->add_action('header', 'myFunction'); // Where myFunction is a valid function
Hooks::getInstance()->add_action('header', 'include_css'); // Where include_css is a valid function
// Method 2
$hooks = Hooks::getInstance();
$hooks->add_action('header', 'myFunction'); // Where myFunction is a valid function
$hooks->add_action('header', 'include_css'); // Where include_css is a valid function

Step 3. Run the callbacks associated with the event

// Method 1
Hooks::getInstance()->run_actions('header');
// Method 2
$hooks = Hooks::getInstance();
$hooks->->run_actions('header')

Using the Helpers

Step 1. Add Hookable Event

add_hookable_event('footer');

Step 2. Add some callbacks to the event

add_action('footer', 'myFunction'); // Where myFunction is a valid function

Step 3. Run the callbacks associated with the event

run_actions('footer');

To Do

• Add a way to specify the running order of actions registered to an event
• Maybe tags like: run_after, run_before, run_first, run_last?
• Make a way to call a callback with an array of data. Read: call_user_func_array
