LLMS_Forms::get_free_enroll_form_fields( LLMS_Access_Plan $plan )

Retrieve an array of form fields used for the “free enrollment” form


Description Description

This is the "one-click" enrollment form used when a logged-in user clicks the "checkout" button from an access plan.

This function converts the checkout form to hidden fields, the result is that users with all required fields will be enrolled into the course with a single click (no need to head to the checkout page) and users who are missing required information will be directed to the checkout page.
