Thanks so much guys! With your help, i got it working :-)
(There are some problems, but i will explain them at the end)
I thought id show exactly what i did, in case anyone else ever finds this post and needs to work it out.
In my validate script, i have the following:
Code:
required: true,
minlength: 4,
remote: "../ajax/checkusername"
},
then, in the
ajax.php file, located in
SITE\system\application\controllers
i have this:
Code:
<?php
//if (!defined('BASEPATH')) exit('No direct script access allowed');
class Ajax extends Controller {
function index()
{
echo 'false';
}
function checkusername()
{
$request = strtolower($_REQUEST['username']);
$query = $this->db->query('SELECT userID FROM users WHERE LOWER(userName) = "'. $request .'"');
if ($query->num_rows() > 0){
echo 'false';
} else {
echo 'true';
}
}
}
?>
It really is great :-), as i only have to have 1 ajax.php file -- and then just add more functions as i need them, and call them like this
../ajax/checkemail or
../ajax/otherfunction instead of the 100's of little ajax files i used to do.
I had to change one line in the
jquery.validate.js plugin file, and that was at line 932, i had to add type: "POST",
Code:
$.ajax($.extend(true, {
url: param,
mode: "abort",
type: "POST",
Thanks kgill and mcr_rm :-) great advice.
I just have two problems now...
I had to comment out the line to check if the file is being loaded directly or not, as it stops it working...
Code:
//if (!defined('BASEPATH')) exit('No direct script access allowed');
This dosnt really matter, though.
Another problem was that i had to disable compression in my config.php file...
Code:
$config['compress_output'] = FALSE;
Otherwise i was getting an error.
I did read there was another way to turn on compression in the php.ini file -- so i will have to look into that (unless anyone wants to post the answer?)
Thanks again for the help!
Regards,
