getting variable name not value

[Anon]

hi folks,

i have a little question wich maybe is very simple but i cant't figure it out without some help...

i have a forum with an image submit button.
like this:

input type=image src=/pathto/$pic name=$pic

$pic is the name of the picture and is stored in a mysql db.

now on pressing the image submit php create like it should be the two variables for the
picture (e.g. "nicechick.gif") $nicechick.gif_x and $nicechick.gif_y...

now my problem is, that i need the name of the image (in this case "nicechick.gif) and not the value for x or y.
how can i handle this?

There is oe thing left...

I have to mention, that i use multiple image submit buttons for one form. Exactly i use 8 image buttons and whant to know wich one the user clicked...

i hope that this will help....

instead of:
input type=image src=/pathto/$pic name=$pic

you should use:
input type=image src=/pathto/$pic name=pic[$pic]

and on action page then you would be able to find what picture was clicked with followin code

$a = array_keys($HTTP_GET_VARS['pic']);
$pic = $a[0];

thx to you!

it works now...

but i don't need to use $HTTP_GET_VARS
This results in an error like this:

first value must be an array in array_keys...

[Anon]

if you submit the form via POST you should of course use $HTTP_POST_VARS instead of the $HTTP_GET_VARS

but it works without it as well ...
