$usr=$this->input->post('name');

$result=$this->user->check_user_exist($usr);
if($result)

echo "false";
}
}
IN MY MODEL


function check_user_exist($usr)
{

$query=$this->db->get_where('ad_users',array('username'=>$usr));
if($query->num_rows()>0)
{
return true;
}
else
{
return false;
}
}

It would help if next time you post that you wrap your code in code tags!

Apart from the above, try to check also if your query return a valid result.

If your js is in a standalone .js file, you can't use php in it unless you configure apache to parse js files as if they were php files, so your base_url() probably isn't working in there. Check firebug/console and see where the request is actually being sent to.

Check whether your values are posting to Controller or not in Firebug Console. If not then you have to check your Ajax post and Base url first. Have a look .. This may help you

Code:

var email_address = $("#email").val();
var password = $("#password").val();
var postData = {
  'email' : email_address,
  'password' : password
};

$.ajax({
     type: "POST",
     url: "some.php",
     data: postData , //assign the var here
     success: function(msg){
        alert( "Data Saved: " + msg );
     }
});
