Hi All – We had to write a function to accomplish this. Got it working. Now that we know how to do it, if anyone needs the same done on their site reach out to ross{at}refreshingdesign.biz for custom development.

I also desperately need an answer to this. I’ve created a custom field with Advanced Custom Fields. It is using the meta key attached_project (verified). When adding a new post from the backend, this field pulls posts from a custom post type and you can select them for use in the theme. However, when adding a Custom Field Form Element to WP User Frontend, you have to submit manual options to select from, rather than it pulling values dynamically? This will obviously not work as it should, the same way it works on the backend. Do we have a solution to this problem? Quite simply, I cannot use WP User Frontend without it pulling possible values for this custom field and posting meta values to it correctly.

Thank you so much for your help!
