I missed the part where he was using an image. Without a value property, I don't see how it could pass anything at all....
A note on my recent post, to emulate register_globals do this:
if (!empty($_SERVER))
extract($_SERVER);
if (!empty($_GET)) {
extract($_GET);
} else if (!empty($HTTP_GET_VARS)) {
extract($HTTP_GET_VARS);
}
if (!empty($_POST)) {
extract($_POST);
} else if (!empty($HTTP_POST_VARS)) {
extract($HTTP_POST_VARS);
}
This registers all of the different arrays.

One of many possible things.
Dependent on the version of PHP you are using, you might have
register_globals set to off in your php.ini file, which is preferable.
In which case you'll have to use
If($_REQUEST['variable'])
Or
If(isset($_REQUEST['variable']))
Second possible is:
I've never really used an image within a link to submit a form. What I
usually do is make the image a submit button, e.g.,<input type="image"
src="path to your image" height="XX" width="XX" border="0"> You could
name it or create a hidden field <input type="hidden" name="register"
value="register">
Then upon form submission (<form action="<? Echo $_SERVER['PHP_SELF']
?>">)
You would look for register
If(isset($_REQUEST['register']))
{
//whatever
}
hope one of them works.

Subject: passing variables
Hello all,
I have a login/register screen for my php/mysql db. When the page
opens,
the user sees the log in screen but I have a button and reloads the same
page, hopefully with the register screen. I know I can simply check to
see
if a variable is set with
if ($variable){} . This does not seem to work when I give an image a
name
and link it to the same page. The image is named register and it links
back
to the same page, so the page loads, I click on the register image , the
page reloads but the variable is not set.
Any ideas?
Thanks,
Eddie
