How to make Meta Box Group work with better-include.php

The better-include.php only add conditions to show/hide whole meta box for a specific page, so it doesn't affect Group extension. Just define groups as normally, nothing changed.

I think there is a misunderstanding here:

- The Group extension is just one kind of field (special one), it acts exactly like other field type like text, file, etc.
- The techniques to show/hide meta boxes are applied for meta boxes only, not for fields, so they're not applied to groups.

But you can do a tricky way like this to achieve what you want:

- Create a meta box
- In that meta box, define only 1 group and put all fields under this group
- Use techniques above to hide whole meta box

Because this meta box contains only 1 group, show/hide this meta box actually show/hide this group.

Hope that helps. If you need anything, please let me know.

Thanks

No problem, it's quite straight forward. Try this code:

Unfortunately the better-include.php method uses old way to register meta boxes (via admin_init hook). This way still works, but you can not use it with rwmb_meta_boxes filter, e.g. if you register meta boxes with rwmb_meta_boxes filter, you can't use better-include.php method.

I'd suggest you use only global $meta_boxes variable to register meta boxes, and remove code to register meta boxes via rwmb_meta_boxes filter.

A better solution is using Meta Box Include Exclude extension, which is tested with Group extension.

The example is well-written in the extension documentation. All you need is just add include or exclude parameter to meta box definition, no need to add custom function for checking like better-include demo.
