The registration form is a necessity for any website collecting user information and it is usually available for all users, but what if we want it to show up for selected users only? Or want to provide exclusive access to users with invitation code? WordPress doesn’t have this feature by default, whereas you can easily implement it using Pie Register plugin.

It’s a Free WordPress Registration Plugin to customize website registration forms with a drag & drop interface.  Pie Register is enriched with exciting features and one of its features allows user registration with the invitation code, which basically helps us in allowing only the preferred users to register to our website.

Here is a quick video tutorial for the feature:


So that’s how Pie Register allows us to create invitation codes, manage, share and track them easily. Invitation codes can be sent by us or other authorized members of our website to someone who wants to register and allows them to access and view the content within. This will limit WordPress access to invite based users only and protect the website from fake registrations, spammers and bots.
