Setting a PHP $_SESSION['var'] using jQuery

Question

I need to set a PHP $_SESSION variable using the jQuery. IF the user clicks on an image I want to save a piece of information associated with that image as a session variab

Answer 1

It works on firefox, if you change onClick() to click() in javascript part.

$("img.foo").click(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});
});
