IE never ceases to piss me off! I’ve been working on this shopping for one of my site, and I have several button’s within the same form, depending on which one you choose will send you to a different page. In my case an update button and checkout button. The problem is with IE, it doesnt recognize a button as a HTML input DOM. The traditional name and value gets translated into ?name=value, in IE it see’s it as a sorta of image map. When you click the image button all it sends are the coordinates on the button you clicked. As in action_update.x=10 action_update.y = 9. Because of that the standard $_REQUEST['action_update'] wont work. Here is the code I used to fix it so I can tell if someone clicked a certain button. Heres the code for the fix.

HTML:

1

<form>
     <input type="image" src="button_image.jpg" name="action_update"
          value="update" />
     <input type="image" src="button_image.jpg" name="action_checkout"
          value="checkout" />
</form>

PHP:

1

10

<?PHP
     if($_REQUEST['action_update']=='update'||
           isset($_REQUEST['action_update_x'])) {
               /* do something */
     }
     if($_REQUEST['action_checkout']=='update'||
          isset($_REQUEST['action_checkout_x'])) {
               /* do something */
     }
?>

Hope that helps
