allowed_block_types_all │ хук-фильтр │ WP 5.8.0

Этот простой пример позволит пользователям использовать только блоки "Heading", "List", "Image" и "Paragraph" - только список разрешенных блоков - все остальные блоки запрещены.

add_filter( 'allowed_block_types_all', 'example_allowed_block_types', 10, 2 );
function example_allowed_block_types( $allowed_block_types, $block_editor_context ) {

	$allowed_block_types = array(
		'core/heading',     // Heading block
		'core/image',       // Image block
		'core/list',        // List block
		'core/paragraph',   // Paragraph block
	);

	return $allowed_block_types;
}

Получим:

Пример того, что находится внутри второго параметра $block_editor_context:

add_filter( 'allowed_block_types_all', function( $allowed_block_types, $block_editor_context ) {

	print_r( $block_editor_context );

	return $allowed_block_types;
}, 10, 2 );

Выведет:

WP_Block_Editor_Context Object (
	[name] => core/edit-post
	[post] => WP_Post Object (
		[ID] => 257
		[post_author] => 1
		[post_date] => 2021-08-23 19:30:21
		[post_date_gmt] => 2021-08-23 16:30:21

		[post_title] => Ketchup
		[post_excerpt] =>

		[ping_status] => closed

	)
)

Пример использование параметра:

add_filter( 'allowed_block_types_all', 'example_allowed_block_types_when_editing_posts', 10, 2 );

function example_allowed_block_types_when_editing_posts( $allowed_block_types, $block_editor_context ) {

	// Only apply in the Editor when editing posts.
	if ( 
		'core/edit-post' === $block_editor_context->name &&
		isset( $block_editor_context->post ) && 
		'post' === $block_editor_context->post->post_type
	) {
		$allowed_block_types = array(
			'core/heading',     // Heading block
			'core/image',       // Image block
			'core/list',        // List block
			'core/paragraph',   // Paragraph block
		);

		return $allowed_block_types;
	}

	// Allow all blocks in the Site Editor or when editing other post types.
	return true;
}

Хук позволяет указать список "разрешенных" блоков. Но если у вас сотни блоков, то удобнее указать только те которые нужно исключить...

Чтобы этого добится мы можем указать ненужные блоки в массиве, затем програмно получить весь список существующих блоков и исключить из них указанные.

В этом коде я оставил список всех блоков, которые у меня были по умолчанию в закомментированном виде, чтобы вы могли скопировать его и раскомментировать те блоки которые вам не нужны.
