how is this jquery app validating the username? (3rd party script)
- by SarmenHB
The tutorial that I'm trying to figure out is this:
http://www.position-absolute.com/articles/jquery-form-validator-because-form-validation-is-a-mess/
The username field looks like this:
<input value="" class="validate[required,custom[noSpecialCaracters],length[0,20],ajax[ajaxUser]]" type="text" name="user" id="user" />
That <input> field has a class item named ajax[ajaxUser] which has its rules contained in this script (jquery.validationEngine-en.js).
The snippet for that item looks like this:
"ajaxUser":{
"file":"validateUser.php",
"extraData":"name=eric",
"alertTextOk":"* This user is available",
"alertTextLoad":"* Loading, please wait",
"alertText":"* This user is already taken"},
What I can't figure out at all is how its PHP page is working which is validateUser.php. Where are all those post fields coming from? I looked around and can't find a field with those names.
Thanks
