TL;DR: The 'Default Value' field for the WYSIWYG editor does not work and I need a solution to prefill it. Tried 'rwmb_before' and can't find any solution in the docs.
How do I correctly use this hook? I read the documentation but I am obviously missing something.
The 'default value' field for the WYSIWYG element is no use, as it is a text field so I am trying to pre-fill the WYSWIG field using the "rwmb_before" hook, but the documentation is limited and does not explain how to get the data from the metabox, and the hook for targetting a specific ID does not appear to work.
The custom field ID: 'district_tax_area_override_content'
1. I have tried the hooks 'rwmb_before_district_tax_area_override_content', 'rwmb_before_{district_tax_area_override_content}', neither work.
2. I have tried 'rwmb_before' which is firing, but I do not know how to get any of the data from the object. No documentation on it that I can find.
3. I would really like to target the 1 metabox, not have to use 'rwmb_before' to index every metabox until it lands on the one I need. Even then, I need to know how to access the data of the object.
