描述

This Easy Digital Downloads extension integrates AJAX calls if you have enabled AJAX in your EDD settings, and require signups at checkout (guest checkout disabled).
 
The EDD AJAX Check Username plugin requires EDD and will deactivate itself when it isn’t present.
 
EDD AJAX Check Username only loads its CSS and jS on the checkout/registration page saving extra bandwidth and loading time.
 
The AJAX checks against illegal usernames, illegal characters and letters and returns an error when present. Current default illegal usernames are: www, web, root, admin, main, invite, administrator. You can add additional names by filtering in your own, see codex below.
 
There is a default minimum character length of three (3) characters, but if you would like more or less see the example function below.
