Can't set customer form error

Hello,

I want to set a customer error message.  Can anyone tell me why this doesn't it appear?

Thanks,

James

PHP Code:

        $this->form_validation->set_rules('username', 'Username', 'trim|required|xss_clean');
        $this->form_validation->set_rules('password', 'Password', 'trim|required|xss_clean');


        if ($this->form_validation->run() == FALSE) {

            $this->load->view('register/header');
            $this->load->view('register/researcher_form');
            $this->load->view('footer');

        } else {

            $username = $this->input->post('username', TRUE);
            $password = $this->input->post('password', TRUE);

            // Check the username and password
            $researcher_id = $this->user->researcher_login($username, $password);

            if ($researcher_id == TRUE){

                redirect("/register/study/");

            } else {

                $this->form_validation->set_message('login failed', 'Your username and password may be wrong.');
                
                $this->load->view('register/header');
                $this->load->view('register/researcher_form');
                $this->load->view('footer');

            }

        }

    }

Just a quick look and im no expert

but "$this->form_validation->set_message" I use when creating a custom validation rule?

to see the error messages on the form after submit is thats what you looking for
i do this in my controller / model

$this->data[ 'submiterrorms' ] = validation_errors( '<p class="error_msg">', '</p>' );

and then have tis in my view

<?php if (! empty($submiterrorms)) { ?>
<?php echo $submiterrorms; ?>
<?php } ?>


or you can just use

<?php echo validation_errors(); ?>

You need to validate the login with a callback.

You can modify mine if you want.

PHP Code:

public function login()
{
    $this->load->helper('form');
    $this->load->library('form_validation');
    
    $validation_rules = array(
        array(
            'field' => 'username',
            'label' => lang('login_email'),
            'rules' => array(
                'trim',
                'valid_email'
            )
        ),
        array(
            'field' => 'password',
            'label' => lang('login_password'),
            'rules' => array(
                'trim',
                'required',
                array('validate_auth', array( $this, '_validate_auth' ) )
            )
        )
    );
    
    $this->form_validation->set_rules( $validation_rules );
    
    if( $this->form_validation->run() === TRUE )
    {
        return TRUE;
    }
    return FALSE;
}

// --------------------------------------------------------------

public function _validate_auth()
{
    $user_email        = $this->input->post('username');
    $user_password    = $this->input->post('password');
    
    if( empty($user_email) OR empty($user_password) )
    {
        $this->form_validation->set_message('validate_auth', lang('error_missing_fields'));                
        return FALSE;
    }
    
    if( $auth_data = $this->auth_model->get_auth_data( $user_email ) )
    {
        if( $auth_data->banned === '1' )
        {
            $this->form_validation->set_message('validate_auth', lang('error_username_password'));
            return FALSE;
        }
        if( ! $this->check_password( $auth_data->passwd, $user_password ) )
        {
            $this->form_validation->set_message('validate_auth', lang('error_username_password'));
        }
        else
        {
            // Setup redirection if redirect required
            $this->redirect_after_login();
                    
            // Set session cookie and remember me
            $this->maintain_state( $auth_data );
            
            // Send the auth data back to the controller
            return TRUE;
        }
    }
    else
    {
        $this->form_validation->set_message('validate_auth', lang('error_username_password'));
    }
    
    return FALSE;
}
