title: passing hidden variable without form and by using link in php
body: <p>I want to know how to pass a (or couple) variable from one page to another in php without any form and by using a link.</p>
  
  <p>I know that session is the best option but how to I implement it in the following scenario:</p>
  
  <p>Delete -> process.php
  Add -> process.php (same page like above)</p>
  
  <p>I want to pass a hidden variable that tells me what link is clicked and hence what function to call. Is there anyway not use $_GET and use sessions?!</p>
  
  <p>Thanks,</p>
