Meta Box

Hi Johannes, I'll check it now and will fix it.

Hi Purdue, can you enable debug and see if there's any error?

Hi, currently it's not available yet. I'll make a note for that and put it on the roadmap.

Hi Martin, I've just released a new version for MB Builder, which fixes this error. Please update.

Hi Mauro,

If you make a query with WP_Query, then by default, WP will automatically fetch meta data for all posts in the query. So, whenever you call get_post_meta (or rwmb_meta, or get_post_custom, e.g. any meta-related functions), there will be no extra queries to the DB made.

See the update_post_meta_cache for the WP_Query. Better explanation can be found here: https://10up.github.io/Engineering-Best-Practices/php/

Probably the changed values are not saved. Can you try saving twice?

Hi, I'm still working on this bug. The function use_block_editor_for_post_type is available on WP 5. Please wait a little if you can't upgrade to WP 5.

I got it. All you need to do is set 'name' => '' for the fields. Then field labels won't appear.
