title: Why are there extra parameters x and y on my GET request?
body: <p>When I hit the submit image I get some extra parameters in the GET request:</p>
  
  <pre><code>main.php?selected=user_manager_main&amp;mode=set_active&amp;set_this_id=13&amp;x=4&amp;y=7
  </code></pre>
  
  <p>Please note the <code>x</code> and <code>y</code> at the end. I certainly did not define the <code>x</code> and <code>y</code> at the end. The values seem to be random. Here is the form code:</p>
  
  <pre><code>echo '&lt;form action ="main.php" method="get"&gt;';
  echo '  &lt;input type="hidden" name="selected" value="user_manager_main" /&gt;';
  echo '  &lt;input type="hidden" name="mode" value="set_inactive" /&gt;';
  echo '  &lt;input type="hidden" name="set_this_id" value="'.$row['USER_ID'].'" /&gt;';
  echo '&lt;input type="image" src="images/delete.gif" alt="Submit" /&gt;';
  echo '&lt;/form&gt;';
  </code></pre>
  
  <p>Any ideas? Thanks!</p>
