title: Instead of Form action and method
body: <pre><code>&lt;?php echo validation_errors(); ?&gt;
  
  &lt;?php echo form_open('form'); ?&gt;
      &lt;input type="text" name="something" /&gt;
      &lt;input type="submit" value="submit"/&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>I find that there is no "action" and "method" as in </p>
  
  <pre><code>&lt;form action="/application/controler/somepage.php" method="POST"&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>in which I would like to get the value entered in the text box after the button submit is pressed. How can I do the same (get the value submitted via POST or GET) as in the former ?</p>
  
  <p>Also, in case I would like to get the value passed in the URL
  <code>http://localhost/index.php/something?value=75&amp;today=Wed</code></p>
  
  <p>that is <code>75</code> and <code>Wed</code>, for example.</p>
