I hope someone can help me with this. I am working on a WordPress-driven directory website, where each directory listing has a contact email address contained in a custom field. I want to use Gravity Forms to add a standard contact form to the listing template, and when the form is submitted, in addition to the admin email, the notification email goes to the email address contained in the previously mentioned custom field.
I have searched the support forms and found the following thread that seems to address the same issue: http://www.gravityhelp.com/forums/topic/email-notification-send-to-email-address-pulled-in-from-post-custom-field
This thread ends with the suggestion of passing the custom field as a hidden field with the form submission. This sounds ace, unfortunately I don't know how to:
1. Pass a custom field value as a hidden field
2. Make use of this custom field value in the WordPress Gravity Forms admin area once I have it.
Any help/pointers greatly appreciated!
