Redirecting like this will not pass the session id in the URL if that is
necessary, which it would be if cookies are not being used. Since you say
it works for you from your provider's system but not your local one, this
suggests that your provider has session.use_cookies turned on, but you have
it turned off.
If this is so, you can solve your immediate problem by turning that option
on in your php.ini, but the redirects will still not work correctly for
anyone who has cookies turned off in their browser. If you are bothered
about this, you need to make use of the handy-dandy SID constant that PHP
helpfully provides, thusly:
header(Location: user.php?action=0.SID);
or, if you're a tidy-URL geek, something like:
header(Location: user.php?action=0.(SID?.SID:));
(BTW, notice the correct spelling of the Location header, with a capital
L; and, yes, others are right when they say it should be a full absolute
URL. These things have been known to matter to some browsers, so it's best
to make a habit of getting them right!)
Cheers!

Re: [PHP-DB] [PHP]: session problem
Are you getting any errors displayed? The php.ini file has to have a directory specified for the session temp variables. I want to use sessions to check wether a user is logged in or not. Therefore,I use session_start and session_register. When I registere the values on the same page, they all seem to work. But when I ask the value of a registered session variable on another page, it is empty?!?! Does anyone know how this comes? i am using session_start() at every page.. i believe it must be in my php.ini setting because on my hosting provider it does work all correctly.. can anyone helpme? -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP-DB] [PHP]: session problem
do you get any output on the second page if you do this?
?php
session_start();
print 'pre';
print_r($_SESSION);
print '/pre';
if ( isset($_SESSION['logged_in'])){
echo Welcome...;
}else{
header(location: user.php?action=9);
}

So, on your second page you NEVER see the Welcome... get echoed out? It
always forwards you to the user.php page?

RE: [PHP-DB] [PHP]: session problem
OK then, couple more questions.
1. What is user.php? Is it the code you posted under second page?
2. Also, on your first page, are you sure that your
$check_user_res = mysql_query($check_user_query) or
die(mysql_error().: $check_user_query);
query is firing properly? If it isn't then your session variables are not
being assigned. I know you said it's working on your host's server, but is
there maybe a small difference between your local and remote databases that
might cause the query to fail when executed locally?
Admittedly, I'm poking around in the dark here.
