I am trying to populate a custom field created with cfs, using the gravity forms edit post plugin. The custom field I have created is ideally a 'relationship' field, but could be any kind of field where the user selects based on the name of another post (custom post type), and the submitted value of the field is the post ID. I then need this value to save in the custom field, and for this not to be unique (multiple values should be able to be added.
I cannot seem to get this to work, and have tried every combination of selects (drop downs), multiselects and textboxes that I can think of, both as the custom field type, and/or the gravity forms field type. It would be fine to just have a drop down on the gravity form, which would save the post IDs as non unique custom fields, but there seems to be no way to get this to work?
Thanks so much in advance for any help you can give.
