title: Submitting form values to controller
body: <p>This should be something really simple but I just can't get it.</p>
  
  <p>I'm learning codeigniter and I have a form with following code</p>
  
  <pre><code>&lt;body&gt;
    &lt;form name ="userinput" action="form_reader.php" method="post"&gt;
        Name &lt;input type="text" name="username"&gt; &lt;br/&gt;
        &lt;input type="submit" value="Submit"&gt;
    &lt;/form&gt;
  </code></pre>
  
  <p></p>
  
  <p>I have a controller called <code>form_reader.php</code> in my controllers folder. I get a <code>404 Not Found</code> error. What am I doing wrong ?</p>
