question: how to pass a variable from model to view

[eluser]Zack Kitzmiller[/eluser]
You can store the error message in a session variable, but I would do that in the controller. It makes for more re-usable code.

In Model:

Code:

function get_name_exists($name){
    $query=$this->db->query("Select * from users where name='".$name."' ;");
        if($query->num_rows()>0){
            return true;
        }
     return false;
}

In Controller

Code:

function some_function() {

    if ($this->some_model->get_name_exists) {
        $this->session->set_userdata('error', 'Username exists');    
    }

}

However, I'd probably tackle this is a completely different way.
