Automatic Default Membership

Like many others I ran into an issue where users would register but not pick a membership level, or their membership would expire and they wouldn’t be able to see content because it would be restricted behind the “free and up” member level wall.

Therefore I created a supplemental plugin to handle it.

I request that code similar to this be incorporated into PMPro.

<?php
/**
 * @package PMPro_Auto_Member_Levels
 * @version 1.0

/*
Plugin Name: PMPro Auto Member Levels
Plugin URI: http://www.dynamicpub.com
Description: Designed to give non members or expired members the default membership level.

You can pick any level but obviously it is for defaulting to the “free” level if you have one. Just drop the code into a blank php file and put that file in your plugins folder.
