Is this possible?

Hey everyone,
I'm fairly new to php and I'm just wondering if it is possible to make an if statement that says that "if a user is logged in it will redirect them to one page, but if the user is not logged in, it will redirect them to a different page. It would need to be somehow tied in to my mysql database (or something to get the info about the users). I can understand if you don't have time to give me the entire code, but a nudge in the right direction would really help. Thanks,

header() to redirect (as long as nothing is otput to the browser first).
sessions for checking who's logged in or not.
There are numerous scripts out there for querying MySQL databases. Have a go and post back if you get stuck

And don't forget output buffering for more control over your php output 😃

Wow this is a bit more complicated than I thought it would be. Here is the basic idea of what I want to do:

<?php
if ( //This is the hard part, I need to use a session to determine if the user is logged in on the forum or not. 
//So, basically if they are logged in.....then

header("Location: http://www.glassin-world.com/gallery"));


else { //stay on current page (I don't know if the else is really necessary) }; 
?>

thats all I have so far. Thanks for the links, but I'm not too sure exactly which sessions or which headers to use. I should have posted this in the newbie section since I am one, but o well. Thanks guys,

Not only is it possible, it's a common question. Remind me sometime to add it to the FAQ.

All of those links have to do with making a log in page. I'm not sure if you read my post or not, but I'm not making a log in page. I have half of it, but all I need is the session part:

<?php 
if (the user is logged in <<<the hard part) 
{ 
} 
$goto = header ("Location: http://www.glassin-world.com/gallery"); 
} 
?> 

something like that, damn now I'm getting frustrated, I didn't think it would be that hard.

Yeah, but you need to know how the log procedure works to know if someone's logged in or not. I've not looked through all of Weedpacket's links, but basically if someone has logged successfully, then the login procedure should set a session variable like:

session_start();
$_SESSION['logged in'] = 1;

then if your IF statement test for the value of that session variable
