Not redirecting with header() command

Report · May 01, 2008

I have this at the bottom of a code block -

if (!$error) {
mysql_select_db($database_connxxxx, $connxxxx);
$Result1 = mysql_query($updateSQL, $connxxxx) or die(mysql_error());

$updateGoTo = "items_Detail.php?ItemID=" . $itemID;
/*die($updateGoTo);*/
header("Location: " . $updateGoTo);
exit();
}

The code executes down to the header() command and leaves me with a blank
page (the exit() command). What's up with that?

Probably not the reason, but still a bug: The Location URI is required
to be absolute.

What about the error_reporting on your dev machine, is it set to
E_ALL|E_STRICT in the php.ini? Do you send any output before the
header() call, which would cause it to fail?

Micha:

The head of the page has this -

<?php ini_set('display_errors', 1); ?>

I get NO error message.

Really? I have always used it as relative and it's worked fine. Anyhow, I
changed this one to absolute with the same results.

And the error_reporting directive? It should be set to E_ALL|E_STRICT.

On a development machine it's better to set these both directives in the
php.ini. The reason is quite simple: If the script has a real error that
causes the parser to die, you would never see any error message and just
get a blank page, because the ini_set() calls will never be executed.

Of course on the production server display_errors should be off and any
errors written to a logfile instead.

That's why I asked for the error_reporting. By default PHP doesn't show
E_NOTICE errors, but sending any output before a header() call causes
exactly that - a notice. With the default PHP setting you won't see it.

It's required by the HTTP spec. With all the different user agents out
there (not only browsers), you can't be sure that all are that forgiving
with relative redirects. At least Lynx even shows a warning.

But I know that the parser is not dieing since the page executes properly
all the way down to the line immediately above the redirect! The data is
added to the database, so I know I am in the loop, and if I insert a die();
command immediately above the redirect, and have it print the redirect
value, that prints properly. So, I am puzzled.

It means there's an error on the page that you're being redirected to.
