Tell us what you are trying to do?
Trying to have taxonomy, featured image and rich text editor required on frontend form and it does not work even with the hooks API
Is there any documentation that you are following? https://toolset.com/forums/topic/make-a-taxonomy-required-in-a-post-form/
I changed tax to listing-category and id to 300 which is the form id and it does not work. I need the featured image form to work as well
Is there a similar example that we can see?
