That's because to use an image as a submit button, you must following the HTML specification. The button is only required to send the x,y coordinates where the image was clicked. You might want to just use a hidden field with a name and a value that you can test to see if the form has been submitted.

and I changed it to:

and it works in IE.

So just "type" is causing the issue. So in this case Firefox is not following the HTML specification?

PFMaBiSmAd · June 16, 2009

FF is doing its' own thing by sending the value="..." attribute, in addition to the x,y coordinates that the specification requires.

Thanks for the reply. This is really interesting to know.

So to send a value I would use a hidden value and put it in here?

.....

if (array_key_exists('send', $_POST)) {

.....

OR you can use <button>.

haku · June 16, 2009

or you can check for send_x or send_y

mallen · June 16, 2009

How would I use <button> How would this be written.?
