Prevent globally usage of certain blocks

Hi Markus,

That’s a good question. I haven’t tried this before, but it looks like you can actually disable blocks from within the post editor. This tutorial has some screenshots showing how it works: https://wplift.com/restrict-disable-gutenberg-blocks/

Hi Ben,

thanks for the link.

As I understood, going via the admin panel is something just for the logged-in user, and not a global setting.

I might use one of the suggested plugins probably.

In the meantime I found a snippet to be placed in the functions.php:

function whitelist_blocks()
{
return array(
'core/heading',
'core/paragraph',
'core/image',
'core/button',
'core/buttons',
'core/list',
'core/list-item',
'core/gallery',
);
}
add_filter('allowed_block_types_all', 'whitelist_blocks');

This works pretty well for my purposes ??

Only limitation: for embeddings that use additional information to define the block, this doesn’t work.

Cheers,
Markus

Nice work!

One thing I would recommend is to install the Code Snippets plugin and move this function from Apex’s functions.php file into there. The danger with adding code to functions.php is that the next time I release an update for Apex, your code will be overwritten, and you’ll have to add it again.

Hi Ben,

thanks for the hint. This also accounts for when using the child theme?

Cheers,
Markus

If you’re using a child theme, then that’s fine. You can safely edit the functions.php file in the child theme and you’ll never lose your changes. It’s only an issue if you edit the functions.php file inside the “parent” theme.

Great! ????
