title: How to reload page containing POST data
body: <p>I've got a section on every page of my site which allows the user to set a reminder. It loads the appropriate form on the page when the <code>$addtracker</code> variable is set in the url using:</p>
  
  <pre><code>$current_url = "http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";?&gt;
  &lt;a href="&lt;?php echo $current_url; ?&gt;&amp;addtracker"&gt; Add reminder&lt;/a&gt;
  </code></pre>
  
  <p>It works on every page except pages which rely on POST data, such as a search results page. When the link is clicked on these pages, the POST data disappears and so I get 0 results in the search and $_POST data not found errors.</p>
  
  <p>How can I reload the current page with the POST data intact?</p>
