Just a day old in CI.

Code in login_view.php

Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

&lt;html &gt;

&lt;head&gt;

&lt;meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /&gt;

&lt;base href="&lt;?php echo $this-&gt;config->item('base_url') ?&gt;application/myapp/" />

&lt;link rel="stylesheet" type="text/css"  href="&lt;?php echo "$base/$css"?&gt;"&gt; 

&lt;title&gt;myapp&lt;/title&gt;

&lt;/head&gt;

&lt;body&gt;

<br>

<br>

<TABLE width="60%" align="center" border="0"cellpadding="0">

    <TD align="left"><img src="images/logo.gif" Alt="Logo"/></TD>

    </tr>

&lt;/form&gt;

</table>

&lt;/body&gt;

&lt;/html&gt;

code in login.php

Code:
&lt;?php

class Login extends Controller {

    function Login()

    {

        parent::Controller();    

        $this->load->helper('url'); 

    }

    function index()

    {

        $data['base']       = $this->config->item('base_url'); 

        $data['css']        = $this->config->item('css');        

        $this->load->helper(array('form', 'url'));        // load form 

        $this->load->library('validation'); // load validations

//          if ($this->input->post('mainform')) {

              $rules['username'] = 'required|trim';

              $rules['password'] = 'required|trim';

              $this->validation->set_rules($rules);

//            }

        if ($this->validation->run() == TRUE)

        {            

            $this->load->view('checkuser' , $data);

        }

        else

        {

            $this->load->view('login_view' , $data);

        }

    }

}

/* End of file welcome.php */

/* Location: ./system/application/controllers/welcome.php */

As soon as i add <input type="text" name="username" value="<?=$this->validation->username;?>" /> instead of <input type="text" name="username" value="" /> i get the error :Undefined property: CI_Validation. Also if i am leaving the fields blank, no serverside validation messages are displayed. where am i wrong

Below is the folder structure
applications
foo
config/
controllers/
errors/
helpers/
hooks/
languages
etc ... etc...

I got the same error and i work around like this

in controller:

Code:
function _validity($v)

    {

        if(isset($this->validation->$v))

        {

            return $this->validation->$v;

        }

        else

        {

            return '';

        }

    }

in View's field value:

Code:
echo $this->_validity('firstname');

You'll need some sort of IF check to see if $this->validation->field actually exists.

You also need to define the fields, as explained in the Validation Guide: http://ellislab.com/codeigniter/user-gui...ation.html See under 'Re-populating the form.'
