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.

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).
