"setting a php $_session['var'] using jquery" Answer’s


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:


<img class="foo" src="img.jpg" />
<img class="foo" src="img2.jpg" />
<img class="foo" src="img3.jpg" />


    // 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):

    // do any authentication first, then add POST variable to session
    $_SESSION['imgsrc'] = $_POST['img'];
