Add a hook to be executed after the hooked method
- Use an "after" hook when you have code that should execute after a hookable method executes.
- One benefit of using an "after" hook is that you can have it modify the return value.
Example
// Attach hook to a method in current object
$this->addHookAfter('Page::path', $this, 'yourHookMethodName');
// Attach hook to an inline function
$this->addHookAfter('Page::path', function($event) { ... });
// Attach hook to a procedural function
$this->addHookAfter('Page::path', 'your_function_name');
// Attach hook from single object instance ($page) to inline function
$page->addHookAfter('path', function($event) { ... });Usage
// basic usage
$string = $wire->addHookAfter($method, $toObject);
// usage with all arguments
$string = $wire->addHookAfter($method, $toObject, $toMethod = null, array $options = []);Arguments
