Alright, I have an AJAX Username checker which goes to check.php with ?user=NAME and I want it so when it returns something with 'Not Available' in it, it will disable the form field.
This is what I have:
Register.php
check.js
check.php
Any help? u.u
This is what I have:
Register.php
Code:
<?php
if($settings->reg_stats == 0){
$Functions->openblock("Registrations Disabled","par");
print "Site registrations have been disabled";
$Functions->closeblock("par");
}else{
if(!$_POST['register']){
$Functions->openblock("Register","frm", "/register/", null, 'reg_frm');
print "<strong>Username</strong>:<br />
<input type=\"text\" name=\"username\" onchange=\"CheckItems(this.value, 'user');\" />
</p>
<div id=\"user_results\"></div>
<p>
<strong>Password</strong>:<br />
<input type=\"password\" name=\"pass\" onchange=\"CheckItems(this.value, 'pass');\" />
</p>
<div id=\"pass_results\"></div>
<p>
<strong>Verify Password</strong>:<br />
<input type=\"password\" name=\"vpwd\" onchange=\"CheckItems(this.value, 'vpass');\" />
