code for login form in codeigniter
<p>I'm still learning my way around in CodeIgniter.</p>

<p>I'd like to create a login form in my codeigniter application.
My view section is below:</p>

<pre><code>&lt;html&gt;
  &lt;head&gt;    
    &lt;title&gt;Jotorres Login Screen | Welcome &lt;/title&gt;
  &lt;/head&gt;
  &lt;body&gt;
    &lt;div id='login_form'&gt;
      &lt;form action="&lt;?php echo base_url();?&gt;Login/process" method='post' name='process' enctype="multipart/form-data"&gt;
        &lt;h2&gt;User Login&lt;/h2&gt;
        &lt;br /&gt;  
        &lt;?php if(! is_null($msg)) echo $msg;?&gt;   
        &lt;label for='username'&gt;Username&lt;/label&gt;
        &lt;input type='text' name='username' id='username' size='25' /&gt;&lt;br /&gt;
        &lt;label for='password'&gt;Password&lt;/label&gt;
        &lt;input type='password' name='password' id='password' size='25' /&gt;&lt;br /&gt;                            
        &lt;input type='Submit' value='Login' /&gt;            
     &lt;/form&gt;
    &lt;/div&gt;
  &lt;/body&gt;
&lt;/html&gt;
</code></pre>

<p>Controller section:</p>

<pre><code>&lt;?php

  if ( ! defined('BASEPATH')) exit('No direct script access allowed');
  /* Author: Jorge Torres
  * Description: Login controller class
  */
  {
    class Login extends CI_Controller{

      function __construct(){
          parent::__construct();
      }


      public function index($msg = NULL){
          // Load our view to be displayed
          // to the user
          $data['msg'] = $msg;
          $this-&gt;load-&gt;view('login_view', $data);
      }


      public function process(){
          // Load the model
          $this-&gt;load-&gt;model('login_model');
          // Validate the user can login
          $result = $this-&gt;login_model-&gt;validate();
          // Now we verify the result
          if(! $result){
              // If user did not validate, then show them login page again
              $msg = '&lt;font color=red&gt;Invalid username and/or password.&lt;/font&gt;&lt;br /&gt;';
              $this-&gt;index($msg);
          }else{
              // If user did validate, 
              // Send them to members area
              redirect('Home');
          }        
      }
    }
  }
?&gt;
</code></pre>

<p>Error Message:</p>

<blockquote>
  <p>The requested URL /afi/Login/process was not found on this server.</p>

<p>How can I resolve this error?</p>

<p>Model section:</p>

<pre><code>&lt;?php

        // grab user input
        $username = $this-&gt;security-&gt;xss_clean($this-&gt;input-&gt;post('username'));
        $password = $this-&gt;security-&gt;xss_clean($this-&gt;input-&gt;post('password'));

        // Prep the query
        $this-&gt;db-&gt;where('username', $username);
        $this-&gt;db-&gt;where('password', $password);

        // Run the query
        $query = $this-&gt;db-&gt;get('users');
        // Let's check if there are any results
        if($query-&gt;num_rows == 1)
        {
            // If there is a user, then create session data
            $row = $query-&gt;row();
            $data = array(

            $this-&gt;session-&gt;set_userdata($data);
            return true;
        }
        // If the previous process did not validate
        // then return false.
        return false;
