Contracts to implement hooks for PoP. The concept of a “hook” is the same as in WordPress: an “action” allows executing extra functionality, and a “filter” allows to modify a value.
Via Composer
composer require getpop/hooks
The source code is hosted on the PoP monorepo, under Engine/packages/hooks
.
Initialize the component:
\PoP\Root\App::stockAndInitializeComponentClasses([([
\PoP\Hooks\Component::class,
]);
Use it:
use PoP\Hooks\Facades\HooksAPIFacade;
// Get an instance of the service
$hooksapi = HooksAPI::getInstance();
// Add a hook for an Action
$hooksapi->addAction($actionName, $functionName, $priority, $argNum);
// Add a hook for a Filter
$hooksapi->addFilter($filterName, $functionName, $priority, $argNum);
// Execute an Action
$hooksapi->doAction($actionName, $param1, $param2, ...);
// Execute a Filter
$filterValue = $hooksapi->applyFilters($filterName, $filterValue, $param1, $param2, ...);
// Remove an Action
$hooksapi->removeAction($actionName, $functionName, $priority, $argNum);
// Remove a Filter
$hooksapi->removeFilter($filterName, $functionName, $priority, $argNum);
PoP uses hooks (as pioneered by WordPress) everywhere, through both functions doAction
and applyFilters
as defined through interface HooksAPI
, allowing any piece of code to be overridable by any 3rd party, or be injected extra functionality. For WordPress, the implementation of the interface is trivial. Other systems can rely on packages to implement this functionality (eg: this one or this one).
Requirements:
- PHP 8.0+ for development
