View source for Pandora - Sample - Validate User Session

This procedure can be used to ensure a valid user session still exists.

If the session has timed-out it will give the user a chance to open a new tab and re-authenticate to the [[SmartSimple]] server rather than losing their work.
* Because the ''confirmusersession'' function is called in the [[savefunc]] and returns false if it fails the page will not be submitted to the server and the page will not be refreshed.


<pre>
</script>
<script type="text/javascript" language="javaScript" src="/Ajax/uta/uta.js"></SCRIPT>
<script language="javaScript">

// savefunc is called on most pages within SmartSimple at the time that the page is saved, saved draft or submitted.
function savefunc(frm){

  //the next line passes the userid of the user that loaded the page to the confirmusersession function.
  // it cancels the save and has an error alert message if the user session no longer exists, or has been taken over by a different user.
  if (!confirmusersession('@me.userid@')) {
      alert('You are no longer logged in, or your login session has been replaced by another user account\n\nPlease open a new window or tab, log back in and re-submit this form');
      return false;
      }

 return true;
}


function confirmusersession(initialuserid){
  ss_developer_key="123456-7qY6n7hLlCsdlhasdlhkdhklgFk=";
  var rs=session_getuser(false,'','userid');
  currentuserid=rs.getfieldbyname(1,"userid");
  if(currentuserid!=initialuserid) return false;
  return true;
}
</pre>
