Strangely, a header("Location") command later on in the script *is* executed. I've output the value of $numprojects, so I know that it's greater than 0, so the command header("Location:managebudget.php?e=1&pid=$pid"); *should* be executed... but it isn't. (Weirdly, if I put a die() command *after* this header() command, it works... but it seems pathologically inelegant to do so.) Obviously, I'm missing something incredibly basic. Can anyone help me figure this out?For one thing, I'd put a space after "Location:" in the header() call. But I've found that this call will sometimes fail (or *look* like it fails) unless you put something like exit(); after it. This terminates execution and forces the script to transfer control as it should. Just make it a habit to always include and exit(); call after your final header() call.
Just make your life easy and create a redirect() function that generates the header instruction, makes a relative URL into an absolute URL and does the exit call. Then you just need to do:
redirect( 'target.php' ); Sooooooooo much simpler :) Cheers, Rob. -- http://www.interjinn.com Application and Templating Framework for PHP -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
