[Resolved] server side image maps - get coords

[Mucello]

I have a form with several inputs. The submit "button" is actually an image and when clicked will submit the form. What I want to do is get the coordinates of the mouse click from that image when submitted. How can I do this in PHP?

Here is the html code for the form:
[FONT=courier new]<form action="ascript.php" method="post" name="mm5">
<INPUT NAME="map" TYPE="image" VALUE="mapvalue" SRC="someimage.gif" width="400" height="129">
</form>[/FONT]

I need the coordinates of where that image was clicked also to be submitted with the form. I think the above code will do that, but how do I get PHP to get those coordinates?

nevermind, I found a solution

For the sake of reference in case someone else has the same problem, here is how I got the coordinates:

$clickedX = $HTTP_POST_VARS['map_x'];
$clickedY = $HTTP_POST_VARS['map_y'];

You're welcome🙂 Took me forever to figure this out and hours of searching Google to find it. In perl, the coordinates are name.x and name.y but in PHP its name_x and name_y. And make sure that 'name_x' in HTTP_POST_VARS['name_x'] is replaced with whatever the input name of your submit image is called _x. I also used GET instead of POST. Using GET appended the form input onto the URL which makes for a dirty URL when there are lots of inputs. So I went with POST instead. Very cool stuff🙂
