Form button problem

I'm trying to use an image for a submit button, the form submits the posted
data back to the same page. I'm using the following code for the image.

echo "<input type=\"image\" src=\"_images/addtobasket.gif\"
name=\"add_to_basket\" value=\"add_to_basket\">";

The trouble is the php that's supposed to handle the posted data is triggered
by an isset, and is looking for the value add_to_basket.

i.e.
if( isset($HTTP_POST_VARS["add_to_basket"]) )
{
echo "YUP GOT THE BALL!";
}

If I use the normal submit

echo "<input type=\"submit\" name=\"add_to_basket\" value=\"add_to_basket\">";

it works just fine.

Can anyone help me on this?

Thanks.

The value of an image field is not passed to the script. The x and y
coordinates of where you clicked the image are. I don't know exactly
what you're trying to accomplish, but this might work:

if( isset($HTTP_POST_VARS["add_to_basket_x"]) )

Gary, you're a superstar. I forgot php replaces periods with underscores when I tried that.

Thanks fella.
