With ACF I’ve created a custom post type that has a custom taxonomy field (also created with ACF). In the custom post type I’m also using Gutenberg editor.
I’ve added the taxonomy field manually with a field group, but found that it is also present in the sidebar. I wanted to hide/remove the taxonomy from the sidebar, but I was not able to do it, even if I selected “No Meta Box” option at the “Visibility” tab of the custom field.
After hours and hours of struggling to find out what I did wrong, I found many Gutenberg-ACF-MetaBox related issues on different blogs, forums and GitHub, and these metabox hiding” of issues seems to be present for years.
However, I also found a GitHub comment from 2019 which – for me at least – actually provided a clean looking fix for this issue.
Here is the comment:
github . com /WordPress/gutenberg/issues/13816#issuecomment-470137667
And here is the code:
add_filter( 'rest_prepare_taxonomy', function( $response, $taxonomy, $request ) {
$context = ! empty( $request['context'] ) ? $request['context'] : 'view';
// Context is edit in the editor
if( $context === 'edit' && $taxonomy->meta_box_cb === false ){
$data_response = $response->get_data();
$data_response['visibility']['show_ui'] = false;
$response->set_data( $data_response );
}
return $response;
}, 10, 3 );
This code checks the taxonomies “meta_box_cb” property and allows modification of the taxonomy data right before it is returned from the rest API. And if the “meta_box_cb” is false, it sets “show_ui” of the metabox to false, so it will not show up in the sidebar.
This actually makes the “No Meta Box” option working with Gutenberg!
Is there any reason why this fix has not been implemented for four years?
Are you planning to implement it in the near future?
If not, at least it would be very important to add a note about this issue next to the “No Meta Box” option to save many hours of unnecessary debugging for the users.
Waiting for an official statement about this.
Best regards,
Zs
