cloakwp / hook-modifiers example snippets


use CloakWP\HookModifiers;

// Apply desired modifiers to an existing hook
HookModifiers::make(['post_type']) // note it accepts an array of multiple modifiers
  ->forFilter('wp_insert_post_data')
  ->register();

// Now you can use the modifier when calling the hook to target a specific post type
add_filter('wp_insert_post_data/post_type=page', function ($data, $postarr, $unsanitized_postarr) {
  $data['post_title'] = 'Page: ' . $data['post_title'];
  return $data;
}, 10, 2);

// The post_type example above is equivalent to:
add_filter('wp_insert_post_data', function ($data, $postarr, $unsanitized_postarr) {
  if ($data['post_type'] === 'page') {
    $data['post_title'] = 'Page: ' . $data['post_title'];
  }
  return $data;
}, 10, 2);


HookModifiers::make(['type'])
  ->forFilter('some_filter_with_many_args')
  ->modifiersArgPosition(2) // 0 indexed, so the third arg is `2`
  ->register();

add_filter('some_filter_with_many_args/type=image', function ($one, $two, $three) {
  // This filter will only run if the arg $three is an associative array with a property 'type' equal to 'image'
}, 10, 3);
