acf Blocks and "allowed_block_types"

Hello.
With acf I was able to successfully integrate several own blocks into Gutenberg. So far everything has fit here – thanks to acf!

Now I wanted to clean up the WordPress backend in the Gutenberg editor and hide some blocks.

As far as I understood it correctly, here is the standard way via function.php and “allowed_block_types”. So I allow all blocks I define here. That works so far, but now also the acf blocks disappear, because I didn’t explicitly allow them!

Here is an excerpt:

function uniques_allowed_block_types( $allowed_blocks ) {
	return array(
		//  Common blocks category
		'core/paragraph',
		'core/image',
		'core/heading',
		'core/gallery',
...

//		'core-embed/tumblr',
//		'core-embed/videopress',
//		'core-embed/wordpress-tv',
//		'core-embed/amazon-kindle',
		//  reusable blocks
		'core/block',
	);
}
add_filter( 'allowed_block_types', 'uniques_allowed_block_types' );

What do I have to do, or what is the correct statement in the array called, so that I can see my blocks in the Gutenberg editor?

best regards

After testing, the answer is acf/YOUR_BLOCK_NAME. You can see the names of all the blocks when you switch to the Gutenberg’s Code Editor – access it from the Gutenberg’s options tab…

This is what I’m using to disable core blocks, and WooCommerce blocks. The core blocks I want to use are at the bottom.

function remove_default_blocks($allowed_blocks){
    // Get widget blocks and registered by plugins blocks
    $registered_blocks = WP_Block_Type_Registry::get_instance()->get_all_registered();

    // Disable Widgets Blocks
    unset($registered_blocks['core/calendar']);
    unset($registered_blocks['core/legacy-widget']);
    unset($registered_blocks['core/rss']);
    unset($registered_blocks['core/search']);
    unset($registered_blocks['core/tag-cloud']);
    unset($registered_blocks['core/latest-comments']);
    unset($registered_blocks['core/archives']);
    unset($registered_blocks['core/categories']);
    unset($registered_blocks['core/latest-posts']);
    unset($registered_blocks['core/shortcode']);

    // Disable WooCommerce Blocks
    unset($registered_blocks['woocommerce/handpicked-products']);
    unset($registered_blocks['woocommerce/product-best-sellers']);
    unset($registered_blocks['woocommerce/product-category']);
    unset($registered_blocks['woocommerce/product-new']);
    unset($registered_blocks['woocommerce/product-on-sale']);
    unset($registered_blocks['woocommerce/product-top-rated']);
    unset($registered_blocks['woocommerce/products-by-attribute']);
    unset($registered_blocks['woocommerce/featured-product']);

    // Now $registered_blocks contains only blocks registered by plugins, but we need keys only
    $registered_blocks = array_keys($registered_blocks);

    // Merge allowed core blocks with plugins blocks
    return array_merge(array(
        'core/image',
        'core/paragraph',
        'core/heading',
        'core/list'
    ), $registered_blocks);
}

add_filter('allowed_block_types', 'remove_default_blocks');

Just to add that even though my ACF block was registered with underscores in the name, these had to be replaced with hyphens in the allowed_block_types() function for it to work!

add_filter( 'allowed_block_types', 'custom_allowed_block_types' );
 
function custom_allowed_block_types( $allowed_blocks ) {
 
    return array(
        'acf/single-text-column',
        'acf/text-image-block'
    );
 
}

Hope this helps someone 🙂
