No need to loop here, you can use an else statment in the next
loop. And the key is inside '' as John pointed out.

Couple things:
. Try not to use abstract names for vars (ie $), it makes the
code harder to understand what its doing. But since this is a
test script I'll let that slide :)
. Your ${$} assingment is never used, read up on how to use
variable variables. It isnt and shouldn't be used in this
instance.
. Try and make things a little simpliler:
foreach ($vars as $)
{
if ( isset($_POST[$]) )
{
$_SESSION[$] = 1; // be sure to assign a value.
}
else
{
unset($_SESSION[$]); // no single quotes around the key
}
}

How about you name your checkboxes as:
name="setting[xx]"
where xx is from your $vars array above. You'll end up with
name="setting[noPlatform]" value="1"
name="setting[noPrice]" value="1"
etc...
Now, you'll have $_POST['setting'] that'll contain the checked boxes.
To put those in session:
$_SESSION['setting'] = $_POST['setting'];
To see which boxes were checked...
$checked = array_keys($_POST['setting']);
or
$checked = array_keys($_SESSION['setting']);
$checked now an array similar to your $vars above but it only contains the
values that were checked.
To find out which checkboxes were NOT checked, you could use:
$not_checked = array_diff($vars,$checked);
Easy, eh?? Hope that helps.

This is no good, now it's going to delete $_SESSION['0'] and so on. This top
function seems OK to me as it was, but using $val in stead of $key should be
clearer.

Re: [PHP] Where am i screwing up?
oh, don't forget, '$key' will not get evaluated. "$key" will.

Re: [PHP] Where am I?
Ok. In the root of the Webserver (Win | Apache) I have a directory called images and one called about. /+root (Win=C:\Inetpub\wwwroot, Apache=/home/../../public_html +-about +-images I call a page in about (/about/index.php). One this page I have a script to open an image file and get the size. DOC_ROOT gives me /root/about. This can go down 'x' number of levels. How do I /root/ dir from anywhere in my site?

Doing a quick scan through the output of phpinfo() on my machine, I can see any one of the following will give me the path (incl. filename of the current script) $HTTP_SERVER_VARS["DOCUMENT_ROOT"] . $PHP_SELF $HTTP_SERVER_VARS["SCRIPT_FILENAME"] $HTTP_SERVER_VARS["PATH_TRANSLATED"] HTH Martin -Original Message- From: Jeff [mailto:[EMAIL PROTECTED]] Sent: Wednesday, December 18, 2002 3:00 PM To: [EMAIL PROTECTED] Subject: Re: [PHP] Where am I?
