[quote author="charly71" date="1352989812"]Try to use Input class library (http://ellislab.com/codeigniter/user-gui...input.html) and then get your username value directly in the model:

Code:

<?php
class Login extends CI_Model {


function login_check()
{
  .....
}

?>

huh? what it has to do with the ajax-request problem ?
