Yes! I did. I replaced all of them. :-(
My code are between because I received this advice from this forum. Is it right?
Thanks.

controller:: form.php

Code:

class Form extends CI_Controller
{    
    public function __construct()
    {
        parent::__construct();
            $this->load->model('signup_model');
    }
    public function index()
    {
        $data['result'] ='';
        $this->load->library('form_validation');
        $this->load->database();
        $this->form_validation->set_rules('email', 'Email', 'required|valid_email', 'E-mail is not valid!');
            if ($this->form_validation->run() == FALSE)
        {
                 $data['result'] = validation_errors();
                 $this->load->view('home', $data);
                   }
        else
        {
            // call model method DB
                $data['result'] = $this->signup_model->create();
                $this->load->view('home', $data);
                }
    }
}

view:: home.php

Code:

<form method="post" action="form">
<p class="space">Sign-up: &lt;input type="text" name="email" value="&lt;?php echo set_value('email'); ?&gt;" size="30" /&gt;
&lt;input type="hidden" name="type" value="&lt;?php echo set_value('type'); ?&gt;" size="50" /&gt;
&lt;input type="submit" class="button" value="Submit" /&gt;&lt;/p>
&lt;/form&gt;
<span>&lt;?php echo $result; ?&gt;</span>
