Reply To: POST meta fields to tags

Hi,

I'm not sure what your field type is. So depending of the field type, we have different solution.

For taxonomy field, as the plugin doesn't store value in post meta, there's no need to submit value via meta_box field. Instead, after creating tags, you should send another request to set post terms, e.g. set the created tags as a term for the post.

For taxonomy_advanced field, the value saved in the DB is the term IDs (separated by commas), not term slugs. So I think you still need to send 2 requests: one for creating tags and gets their IDs, one for adding those IDs to post meta via meta_box.

I hope that makes sense.
