title: Trying to set default checkbox value if not checked
body: <p>Basically I can get the value that applies to when the box is ticked (= 1), but I can't get it to send the default value of 0 when not checked.</p>
  
  <pre><code>&lt;input type="checkbox" name="post_friend" value="1"&gt;
  </code></pre>
  
  <p>I've searched around and someone suggested setting a hidden checkbox, but it's not working for me.</p>
  
  <pre><code>&lt;input type="hidden" name="post_friend" value="0"&gt;
  </code></pre>
