Hmmm, I think, You can do it by adding a cookie value with your javascript, and update your session in php on the NEXT PAGE REFERESH, with reference to that cookie value. I haven't tried it, and i don't think there is way we can update the session from just client side with javascript. Thanks |

No ajax? ok, The browser will try to load the image by requesting the url. Obviously it will be a fools errand, but your php script will get executed and the value available in php's |

You can't really. Session data is altered with the server, while Javascript can only alter client-side data (such as cookies). You can, however, create a solution by creating a new PHP page that passes a variable within the GET/POST request, then alters the session. |

The only alternative I can think of is using javascript to set a parameter in the URL which you could interpret later with PHP, but that would be after another page load. see this post for a method to achive this edit: I don't think this will achive what you after on second thought, but I'll leave the answer just in-case |

PHP session variable resides on the server: http://www.w3schools.com/PHP/php_sessions.asp but the JavaScript values are on client-end only. There should be a mechanism to send this to server, if not using ajax: try saving this value into a hidden field and then sending it using usual get/post. |
