The question mark and colon is the equivalent for the iif function. It's a
'if () ...' is not a function it's a language construct. they are different :-)
for instance 'echo' is also a language construct which is why it does not require
brackets e.g.
$space = ' ';
echo "hello",$space,"world";
short hand for if/else. You start with the expression, and if true, do
what's after the question mark and if false, after the column.

I have never really used this abreviated format before
why the question mark and the colon? What is the long hang eqivalent.
I turned magic quotes off too.

That's because before the submit button has been pressed, $_POST is empty
and so 'heading' is indeed an undefined index. Try:
$heading_insert = isset( $_POST['heading'] ) ? stripslashes(
$_POST['heading'] ) : '';
By the way, while you're switching register_globals off, it might be a
good idea to also switch off magic_quotes_gpc (the reason you need
stripslashes() above) and short_open_tag (judging by your use of the
non-portable <? open tag rather than <?php).
