register_globals in php.ini should be set to On in order for that to work...

Thanks. I was under the impression that those with an opposite problem had
to enable the value. I had just come across this solution earlier today and
was going ot try it when I get the chance.

Mike,
The $GLOBALS array contains references to all variables defined in the global
scope. By using the keyword global, you define a variable in the global scope
(and then make it accessible through $GLOBALS).
The superglobals (eg _POST, _GET, etc) don't get this automatically, because
they are "scopeless".
It would only work if you used the following code beforehand:
global $_POST['photo'];
hth.

Oh, and to answer your original question: yes, as far as I am aware
register_globals would have to be on for that code to work.

Hmm... I think the first part of foreach should be an array... So, more
like
foreach($GLOBALS as $photo)... Unless photo is an array containing photos...
However, how to make a variable become global, I'm not sure of...

Another newbie on PHP here. say I have this simple PHP code:
<HTML><HEAD>
<TITLE>Simple Input</TITLE>
</HEAD><BODY>
<FORM ACTION="post.php" METHOD="post">
Your name: <BR>
<INPUT TYPE="text" NAME="name"><BR>
<INPUT TYPE="submit">
<INPUT TYPE="reset"></FORM>
</BODY></HTML>
So I'm sending 'name' to post.php but I also want to send another variable, say
'school' which has a fixed default value. But of course I dont need to (and don't want
to) put the 'school' field on the form.
So question is how do I send the school value when the submit button is pressed?
thanks in advance.

This is actually an HTML question. Use:
<input type="hidden" name="school" value="Pepperdine">

That's wise since it would constitute a possible security
hole by doing so.

This is an contradictive requirement compared to the previous one.
You can not do it! Either you send the variable via the FROM with
the HTML-tag HIDDEN (breaks first requirements), or you keep some
kind of session state variables on the server side (breaks second
requirments), but you can't do it both.
It up to you wich one of the requriments you want to drop. ;)
