For the first time in my life, I used XOR!

[filburt1]

Simplified thanks to Excel's godawful boolean functions:

PHP Code:

if (($_REQUEST['p'] and $_REQUEST['postid']) or !($_REQUEST['p'] and $_REQUEST['postid'])) 


Doesn't make sense what you're trying to do:

a	b	a xor b	not (a xor b)
TRUE	TRUE	FALSE	TRUE
TRUE	FALSE	TRUE	FALSE
FALSE	TRUE	TRUE	FALSE
FALSE	FALSE	FALSE	TRUE

If we were dealing strictly with booleans instead of this stupid PHP typeless system, it would be as blissfully simple as:

PHP Code:

if ($_REQUEST['p'] == $_REQUEST['postid'])
