Question

it is possible to insert in a database(e.g. MySQL) some values or informations like alt attribute when an image is clicked? How could I do that?
Thanks in advance!

Answer 1

Yes, you can do that easily with Jquery and some server side processing.

$("#myimage").click(function() {
   var $myimage=$(this);
   $.ajax({
       type: 'POST',
       url: 'myserverpage.php',
       data: { img_url: $myimage).attr('href'), 'img_alt': $myimage.attr('alt') },
       success: function(){
            console.log("OK!");
       }
   });
});

In your page myserverpage.php you can find the POST array the values you set in the Ajax request.
