How can i register my custom Gutenberg Block category?
I’ve tried something like:
function my_plugin_block_categories( $categories, $post ) {
if ( $post->post_type !== 'my_post_type' ) {
return $categories;
}
return array_merge(
array(
array(
'slug' => 'example',
'title' => 'Example',
'icon' => 'wordpress',
),
),
$categories
);
}
add_filter( 'block_categories', 'my_plugin_block_categories', 10, 2 );
acf_register_block_type(array(
...
'category' => 'example',
...
However, no category with the name is displayed. Neither in posts nor pages.
🙄 Of course, I found the solution shortly after the post.
function example_block_category( $categories, $post ) {
return array_merge(
$categories,
array(
array(
'slug' => 'example',
'title' => 'Example',
),
)
);
}
add_filter( 'block_categories', 'example_block_category', 10, 2);
Just in case anyone gets here after searching for how to do this, after WordPress 5.8 the filter to be used is now block_categories_all.
So, all would stay the same but use that instead:
add_filter(‘block_categories_all’, ‘example_block_category’, 10, 2);
See: https://developer.wordpress.org/reference/hooks/block_categories_all/
