using jquery ajax with codeigniter

[eluser]charly71[/eluser]
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()
{
  $username = $this->input->post('username');
  $this -> db -> select('id, username');
  $this -> db -> from('users');
  $this -> db -> where('username = ' . "'" . $username . "'");
  $this -> db -> limit(1);

  $query = $this -> db -> get();

  if($query -> num_rows() >= 1)
  {
   return true;
  } else
   return false;
}
}

?>

Bye
