Form validation OUTPUT problems

[eluser]hugle[/eluser]
Hello Everyone.

I'm currently trying out CodeIgniter validation. And came up with some problems.

I have a function in my controller:

Code:

function register_form() {
        $this->load->helper(array('form', 'url'));
        
        $this->load->library('validation');
            
        $rules['username']    = "required";
        $rules['password']    = "trim|required|matches[passconf]";
        $rules['passconf']    = "required";
        $rules['email']        = "required|valid_email";
        
        $this->validation->set_error_delimiters('<li>', '</li>');
        
        $this->validation->set_rules($rules);
        
        $fields['username']    = 'Username';
        $fields['password']    = 'Password';
        $fields['passconf']    = 'Password Confirmation';
        $fields['email']    = 'Email Address';

        $this->validation->set_fields($fields);
            
        if ($this->validation->run() == FALSE)
        {
            $out = $this->load->view('myform');
        }
        else
        {
            $out = $this->load->view('formsuccess');
        }
        
        return ($out);
    }

(this function is basicaly from user guide)

Later, in 'function index' I do:
$content['middle'] = $this->register_form();

if I try to echo $content['middle'] I get empty page.

But If I for example try to navigate directrly index.php/register_form
I get myform.php view.


after some testings, I came up that:

when I change:

Code:

if ($this->validation->run() == FALSE)
        {
            $out = $this->load->view('myform');
        }
        else
        {
            $out = $this->load->view('formsuccess');
        }

to smth like:

Code:

if ($this->validation->run() == FALSE)
        {
            $out = "a";
        }
        else
        {
            $out = "b";
        }

I get output: "a" while accessing function index.


What I'm missing here or doing wrong?

Thanks everyone for help

cheers,

The 3rd argument for the view method needs to be set to true to return output as a string. You are also not passing it any data in the 2nd parameter.
