Library for handling hooks.

Requirements

This library is supported by PHP versions 5.6 or higher and is compatible with HHVM versions 3.0 or higher.

Installation

The preferred way to install this extension is through Composer.

To install PHP Hook library, simply:

$ composer require Josantonius/Hook

The previous command will only install the necessary files, if you prefer to download the entire source code you can use:

$ composer require Josantonius/Hook --prefer-source

You can also clone the complete repository with Git:

$ git clone https://github.com/Josantonius/PHP-Hook.git

Or install it manually:

Download Hook.php:

$ wget https://raw.githubusercontent.com/Josantonius/PHP-Hook/master/src/Hook.php

Available Methods

Available methods in this library:

- Get Hook instance:

Hook::getInstance();
Attribute Description Type Required Default
$id Unique ID for multiple instances. string No '0'

# Return (object) → Hook instance

- Set method name for use singleton pattern:

Hook::setSingletonName($method);
Attribute Description Type Required Default
$method Set method name for use singleton pattern. callable No

# Return (void)

- Attach custom function to action hook:

Hook::addAction($tag, $function, $priority, $args);
Attribute Description Type Required Default
$tag Action hook name. string Yes
$function Function to attach to action hook. callable Yes
$priority Order in which the action is executed. int No 8
$args Number of arguments accepted. int No 0

# Return (boolean)

- Add actions hooks from array:

Hook::addActions($actions);
Attribute Description Type Required Default
$actions Actions hooks array Yes

# Return (boolean)

- Run all hooks attached to the hook:

By default it will look for getInstance method to use singleton pattern and create a single instance of the class. If it does not exist it will create a new object.

Hook::doAction($tag, $args, $remove);
Attribute Description Type Required Default
$tag Action hook name string Yes
$args Optional arguments mixed No array()
$remove Delete hook after executing actions boolean No true

# Return (mixed|false) → output of the last action or false

- Returns the current action hook:

Hook::current();

# Return (string|false) → current action hook

- Check if there is a certain action hook:

Hook::isAction($tag);
Attribute Description Type Required Default
$tag Action hook name string Yes

# Return (boolean)

Quick Start

To use this library with Composer:

require __DIR__ . '/vendor/autoload.php';

use Josantonius\Hook\Hook;

Or If you installed it manually, use it:

require_once __DIR__ . '/Hook.php';

use Josantonius\Hook\Hook;

Usage

Example of use for this library:

- Add action hook:

Hook::addAction('css', ['Josantonius\Hook\Test\Example', 'css']);

- Add action hook with priority:

Hook::addAction('js', ['Josantonius\Hook\Test\Example', 'js'], 1);

- Add action hook with priority and arguments number:

$instance = new Example;

Hook::addAction('meta', [$instance, 'meta'], 2, 1);

- Add action hook and set singleton method:

Hook::setSingletonName('singletonMethod');

$instance = call_user_func(
    'Josantonius\Hook\Test\Example::singletonMethod'
);

Hook::addAction('article', [$instance, 'article'], 3, 0);

- Add multiple action hooks:

$instance = new Example;
        
Hook::addActions([
    ['after-body', [$instance, 'afterBody'], 4, 0],
    ['footer', [$instance, 'footer'], 5, 0],
]);

- Add multiple action hooks and set singleton method:

Hook::setSingletonName('singletonMethod');

$instance = call_user_func(
    'Josantonius\Hook\Test\Example::singletonMethod'
);

Hook::addActions([
    ['slide', [$instance, 'slide'], 6, 0],
    ['form', [$instance, 'form'], 7, 2],
]);

- Check if is action:

Hook::setSingletonName('singletonMethod');

Hook::isAction('meta');

- Execute action hooks:

Hook::doAction('css');
Hook::doAction('js');
Hook::doAction('after-body');
Hook::doAction('article');
Hook::doAction('footer');

- Execute action hook with arguments:

Hook::doAction('meta', 'The title');
Hook::doAction('form', ['input', 'select']);
