title: Use a submit <button> instead of <input> button
body: <p>i want to submit a form with <code>&lt;button&gt;</code> instead of <code>&lt;input&gt;</code>.
  I know a <code>&lt;button&gt;</code> cant handle the form like a submit <code>&lt;input&gt;</code> and i have to use the onclick method.</p>
  
  <p>I tried several things but it doesn't work</p>
  
  <pre><code>&lt;button name="&lt;?php echo $name; ?&gt;" onclick="document.&lt;?php echo $this-&gt;action; ?&gt;.submit()"&gt; ... ( Action URL of the form )
  &lt;button name="&lt;?php echo $name; ?&gt;" onclick="document.iso&lt;?php echo rand(); ?&gt;.submit()"&gt;... ( name of the form )
  &lt;button name="&lt;?php echo $name; ?&gt;" onclick="window.location.href='&lt;?php echo $this-&gt;action; ?&gt;'"&gt;... ( Action url of the form )
  </code></pre>
  
  <p>Does someone know an answer ?</p>
