Goals

Using PSR-11 container implementation in WordPress plugins, themes and packages during WordPress action/filter callbacks.

Dependencies are usually lazy loaded(depends on your container implementation), not instantiated until the first time they are used (during WordPress action/filter callbacks).

Installation

Installation should be done via composer, details of how to install composer can be found at https://getcomposer.org/.

You need a psr/container-implementation package as well. This readme uses league/container as an example (any psr/container-implementation works similarly).

# league/container is an example, any psr/container-implementation package works
$ composer require typisttech/wp-contained-hook league/container

Usage

use League\Container\Container;
use TypistTech\WPContainedHook\Hooks\Action;
use TypistTech\WPContainedHook\Hooks\Filter;
use TypistTech\WPContainedHook\Loader;

$container = new Container;

// Configure the container.
// This depends on your `psr/container-implementation`.
$container->add('bar', Bar::class);
$container->add('foo', Foo::class);

// Action.
$action = new Action('bar', 'admin_init', 'doSomething');

// Filter.
$filter = new Filter('foo', 'the_content', 'filterSomething');

// Add to loader.
$loader = new Loader($container);
$loader->add($action, $filter);

// Add to WordPress.
$loader->run();

In plain WordPress, the above is similar to:

$bar = new Bar();
add_action('admin_init', [$bar, 'doSomething'])

$foo = new Foo();
add_filter('the_content', [$foo, 'filterSomething'])

In WordPress plus container, the above is similar to:

add_action('admin_init', function ($arg) use ($container): void {
  $bar = $container->get('bar');
  $bar->doSomething($arg);
})

add_filter('the_content', function ($arg) use ($container) {
  $foo = $container->get('foo');
  return $foo->filterSomething($arg);
})

API

TypistTech\WPContainedHook\Loader

Register all actions and filters for the plugin/package/theme.

Maintain a list of all hooks that are registered throughout the plugin, and register them with the WordPress API. Call the run function to execute the list of actions and filters.

Loader Constructor

• @param Psr\Container\ContainerInterface $container The container.

Example:

$container = new Container;
$loader = new Loader($container);

Loader::add(HookInterface ...$hooks)

Add new hooks to the collection to be registered with WordPress.

• @param HookInterface|HookInterface[] ...$hooks Hooks to be registered.

Example:

// Action.
$action = new Action(SomeClass::class, 'plugin_loaded', 'doSomething');

// Filter.
$filter = new Filter(SomeClass::class, 'the_content', 'filterSomething');

// Add to loader
$loader->add($action, $filter);

Loader::run()

Register the hooks to the container and WordPress.

Example:

$loader->run();

Hooks: Action and Filter

Holds necessary information for an action or a filter.

Both Action and Filter are subclasses of AbstractHook and implements HookInterface.

AbstractHook Constructor.

• @param string $hook The name of the WordPress hook that is being registered.
• @param string $classIdentifier Identifier of the entry to look for from container.
• @param string $callbackMethod The callback method name.
• @param int|null $priority Optional.The priority at which the function should be fired. Default is 10.
• @param int|null $acceptedArgs Optional. The number of arguments that should be passed to the $callback. Default is 1.

Example:

$action = new Action('bar', 'admin_init', 'doSomething', 20, 2);

$filter = new Filter('foo', 'the_content', 'filterSomething', 20, 2);

FAQs

Will you add support for older PHP versions?

Never! This plugin will only work on actively supported PHP versions.

Don't use it on end of life or security fixes only PHP versions.
