The Invite Only Add On allows you to restrict membership signups for specific membership levels and require an invite code.
Table of contents
How it Works
After completing their membership checkout, your member will receive a unique invite code that they can share with others. You can specify the number of uses on the invite code, make it unlimited, or give the member multiple single-use codes.
A list of used/unused invite code(s) is displayed on the Membership Account page, allowing a member to see who has used their code to register and manage the unused codes tied to their account.
The admin can increase the number of invites available for a user on the “Edit User” page.
Installation
You must have the Paid Memberships Pro plugin installed and activated with a valid license type to use this Add On.
- Navigate to Memberships > Add Ons in the WordPress admin.
- Locate the Add On and click “Install Now”.
- To install this plugin manually, download the .zip file above, then upload the compressed directory via the Plugins > Add New > Upload Plugin screen in the WordPress admin.
- Activate the plugin through the Plugins screen in the WordPress admin.
Configuration
Set the following globals and constants in your site using your preferred method to make customizations to your membership site.
global $pmproio_invite_required_levels; $pmproio_invite_required_levels = array(1);
A comma-separated list of Membership Level IDs that require an invite code.
global $pmproio_invite_given_levels; $pmproio_invite_given_levels = array(1);
(Optional) Specify if only specific levels should be given invite codes to share. Defaults to the value set for $pmproio_invite_required_levels
.
define( 'PMPROIO_CODES', 1 );
(Optional) Set the number of invite codes to be created at checkout (the maximum a user can get without admin intervention). Default: 1.
Note: If you set this to create a large number of codes (more than 25), you may experience a very slow checkout process or even that your checkout process crashes. Please test your checkout process and consider working with your host or developer if you need to optimize the process. Or, consider using few codes that have more uses using the PMPROIO_CODES_USES
constant below.
define( 'PMPROIO_CODES_USES', false);
(Optional) Set the number of times each code can be used. Default: false.
Set this constant to false
for an invite code with unlimited uses. Or, set this constant to a specific numerical value to limit how many times the invite code can be used.
