I’m the author of WP Referral (http://codecanyon.net/item/wordpress-referral-plugin/5393776) and I would like to have a solution in order to integrate UserPro with WP Referral. Many of our customers are requesting this integration.

Basically on user registration we need to have a hidden field referral_id with the value from ref cookie and of course that info should go in user_meta table as meta_key=’referral_id’ with meta_value=$_GET[‘ref’].

Thank you for your assistance.

Best Regards,

That should be so simple! There are hooks in register do_action(‘userpro_before_fields’, $hook_args); I already use it to post HIDDEN inputs, like nonce. You can use that hook to add a hidden input or any kind of inputs before fields. These fields can later be processed after new registration – there’s another hook that runs when profile is updated (e.g. when someone register, edit profile, etc)

do_action(‘userpro_profile_update’, $form, $user_id);

These 2 hooks allow you to connect any custom fields 🙂 referral id could be just one example.

Here it’s

do_action(‘userpro_after_new_registration’, $user_id);
