I am processing my field value through htmlspecialchars() before saving to db.
When I edit the field via the Frontend Submission extension, I want to run the field through htmlspecialchars_decode() before it's displayed in the frontend form.
How can I do that? Is there a filter before loading a field in the frontend form?
To process the field value before saving it to the database, you can use the filter hook rwmb_{$field_type}_value or use the sanitize callback function. And use the filter hook rwmb_field_meta to change the field value before displaying it in the editing form.
