My site has 2 gravity forms, each of which create a custom post type entry. The forms are essentially the same, except one allows free registration and the other drives registrants via Paypal (we are using the GF Paypal add-on) before the post type entry is created. The forms contain multiple taxonomies, which are set up in the form, and populated via this code... Gist Code.
When the free form is used, the taxonomies are populated correctly when the custom post type entry is added. However, when we go via Paypal all the other custom post type entries are populated except the custom taxonomies.
I have a feeling that between Paypal and the website these are being dropped somewhere. Do you have any ideas where?
