How to set a PHP SESSION Variable Value when clicked on <href>

[samdipankar]

I have a code in PHP, where I trying to set a value of a session variable to '1' only when user clicks on it. Otherwise it should not set the value of session variable.

      echo '<a href="page2.php?idfilter=' . $filter_sector 
      . '">' .$filter_sector. '</a>';
 
      if(isset($_GET['idfilter'])) 
      {$_SESSION['idfilter'] = $_GET['idfilter']; 
      $_SESSION['counter'] =1;} else { $_GET['idfilter'] =
      '' ;}

I'm guessing those two blocks of code are on different pages. You haven't told us what is the problem with the code. Are you getting errors?

Your code does not have any problem. But your
else statement does not mean anything except wasting processing time.

And make sure you have started your session in this page. You must have to start your session every page. the concerned function is session_start()
