title: can we pass $_POST value by clicking link?
body: <p>I need to build some php API to upload an image cross subdomain.</p>
  
  <p>Example, upload script located at <a href="http://sub.domain.com/upload.php" rel="nofollow noreferrer">http://sub.domain.com/upload.php</a></p>
  
  <p>and I neew to upload an image to <a href="http://www.domain.com/media/" rel="nofollow noreferrer">http://www.domain.com/media/</a></p>
  
  <p>I read some content at <a href="http://www.v-nessa.net/2009/02/09/simple-api-writing-part-i" rel="nofollow noreferrer">http://www.v-nessa.net/2009/02/09/simple-api-writing-part-i</a> and i suspect that can we pass $_POST value by clicking link? How?</p>
