WordPress plugin to make it easier to create block patterns.

As the title states, this plugin does not work when using allowed_block_types_all filter.

add_filter('allowed_block_types_all', function($allowed) use ($app) {
  // I've ignored $allowed deliberately in this case, since it always contains `true` in my case.

  $core = [
    'core/block', // required for reusable blocks
    'core/template', // see above

    // Core has like 200 different blocks and 190 of them are trash.
    'core/paragraph',
    'core/image',
    'core/heading',
    'core/list',
    'core/nextpage',
    'core/separator',
    'core/shortcode',
    'core/embed',
    'core/columns',
  ];

  $acfBlocks = [];

  foreach ($app->getBlocks() as $block) {
    $acfBlocks[] = 'acf/' . strtolower($block->getName());
  }

  return array_merge($core, $acfBlocks);
}, PHP_INT_MAX); // This ensures that the only blocks available are blocks that work in our custom theme

There are no patterns available. (I've also disabled all core patterns because they look like trash)

Disabling the filter (and thus making the editor way harder to use w/ the useless block bloat) makes the plugin work.

I don't have many ideas on how to solve this problem properly from the plugin directly. The one that I do have?

Gather the templet handles, and call allowed_block_types_all filter:

add_filter('allowed_block_types_all', function($allowed) {
  // loop and build the array 
  return array_merge($allowed, [
   "templet/test222"
  ]);
}, 100000); // Late priority so plugins and themes have already set the value 

Then, I might be able to check if $allowed contains something else than true (the dumb default WP chose) and merge it with my own whitelist.

I say might, because I added "templet/test222" to my whitelist and that doesn't work.

Then there's also the fun case of "using allowed_block_types_all filter requires you to whitelist each and every block manually", which means that if the site isn't already using the filter, using it in this plugin would make every block unavailable. You just might be able to work around that issue by checking the contents of $allowed, and if it's not an array, return the value as is.
