Check if value exists in database?

[eluser]invision[/eluser]
Hi,

I have a very simple model for adding users to my database.

Code:

function userExists() {    
        $email = $this->input->post('email');        
        $this->db->where("email",$email);
        $Q = $this->db->get('users');
        if ($Q->num_rows() > 0){
            return TRUE;
        }
    }

I run this in my Controller with:

Code:

if ($this->MUsers->userExists() == TRUE)
{
    die('bla - exists');
}

Now I wonder, how do I send the message back to my form page and still keep the form elements in place?

I basically just want to add a warning message above my form explaining the email is taken.



Many thanks for any help.
