Limit Gutenberg blocks available to users to choose from
I am using the
allowed_block_types_all
filter to choose certain blocks the users can choose from. I have just added one here as an example. This works fine but my issue comes in when trying to choose embeds.
add_filter( 'allowed_block_types_all', 'usr_allowed_block_types' );
function usr_allowed_block_types( $allowed_blocks ) {
return array(
'core/paragraph',
'core-embed/twitter'
);
}
I see the paragraph but not twitter. If I add
core/embed
then I get ALL embeds which I really don't want.
Solutions
In the functions. php file I added
add_filter( 'allowed_block_types_all', 'func_allowed_block_types' );
function func_allowed_block_types( $allowed_blocks ) {
return array(
'core/embed'
);
}
Then in my plugin I added this JS to the javascript file to enable only the embed blocks I wanted (Twitter, youTube and Vimeo)
wp.domReady( function() {
const allowedEmbedBlocks = [
'twitter','youtube', 'vimeo'
];
wp.blocks.getBlockType( 'core/embed' ).variations.forEach( function( blockVariation ) {
if (
allowedEmbedBlocks.indexOf( blockVariation.name ) === -1
) {
wp.blocks.unregisterBlockVariation( 'core/embed', blockVariation.name );
}
} );
} );
