session changed after reload

[eclipsevtb]

Hi, I have some code using session variable:

<?
   session_start();
   echo "a:{$_SESSION['a']}";
?>

<a href="#" onClick="<? $_SESSION['a']++; ?>">add by 1</a>

$SESSION['a'] keep increment when I reload the page but that's not I want.
What should I do if I want to have $SESSION['a'] modified by pressing the link ONLY? 🙁

Is it possible to keep $_SESSION['a'] unchanged after reload?

Thanks a lot

//if the page name is page.php
<?
session_start();

if(isset($_GET['a'])){
   $_SESSION['a']++;
}

echo "a:{$_SESSION['a']}";

?>

<a href="page.php?a">add by 1</a>

The way you tried can't work because PHP will only see the increment order whenever the page loads and not when the onClick method is called (can't mix JS and PHP in that way)...

This way only if a variabe $GET['a'] is set the $SESSION['a'] will increment...
