Simple membership plugin has an option that can be used to let the user complete registration for paid membership from the “Thank You” page (after the payment).
Normally, if you are offering paid memberships then the users get an email with a special link to complete the registration after they make a payment. The feature explained on this page allows you to offer a solution whereby the customers can view the special registration link on the thank you page after payment.
The following steps show how to use this optional feature:
Step 1) Create a “Thank You” page (where your visitors will land after they make the membership payment).
Step 2) Add the following shortcode to this newly created “Thank You” page:
You can also add extra message (that will be helpful to your members) in this page if you want to.
Step 3) Edit your membership payment button from the “Payments” menu of the plugin.
Step 4) Use the URL Of this “Thank You” page in the “Return URL” field of the payment button.
Now, when the members land on the thank you page after the payment, they will be given an option to click on a special link to complete the paid registration.
