Setting a PHP $_SESSION['var'] using jQuery
You can't do it through jQuery alone; you'll need a combination of Ajax (which you can do with jQuery) and a PHP back-end. A very simple version might look like this:
HTML:
<img class="foo" src="img.jpg" /><img class="foo" src="img2.jpg" /><img class="foo" src="img3.jpg" />Javascript:
$("img.foo").onclick(function(){ // Get the src of the image var src = $(this).attr("src"); // Send Ajax request to backend.php, with src set as "img" in the POST data $.post("/backend.php", {"img": src});});PHP (backend.php):
<?php // do any authentication first, then add POST variable to session $_SESSION['imgsrc'] = $_POST['img'];?>
Might want to try putting the PHP function on another PHP page, and use an AJAX call to set the variable.
