That filter can be placed in your own plugin or in the theme functions.php.
That only allows the basic functionality from what I have tested.
Also I have no clue about what Types want to do. I already created a patch for them to fix their issues but till now I didn’t got any response at it. I modified their plugin what you can find here: https://github.com/markoheijnen/types/tree/use-hook-add_meta_boxes. That one should work perfect with Tabify Edit Screen.
It’s not my problem to solve. Thats also why I have a filter to allow some plugin support. I don’t enable that by default for possible issues later on.
Okay, thank for the feedback.
I’m going to push the guys at Types hard to fix this and work with you. They have such a useful plugin, but they should be using standards to ensure its broadly compatible. It’s unfortunate and frustrating when plugin developers start doing really proprietary stuff in their coding.
In this case they don’t use the correct way of adding meta boxes with the filter ‘add_meta_boxes’. And because of that they now check if they are on the edit post page.
I wanted to add that I downloaded and installed your modified version of Types and I’m really impressed. I’ve got a custom post type with nearly 30 custom fields in different sections. Your plugin really shines and makes that interface totally understandable and usable now.
I hope the Types folks accept your patch, I know other custom post type plugin developers have, they really should be now different.
Thank you for creating such a useful and impressive plugin!
I guess Types is the only plugin left what doesn’t work. I love Pods Framework the most since the developer came to me for fixing it.
Hoping they will fix it soon so there is one plugin less what doesn’t work with my plugin.
