Syntax change for new $_SESSION

[Duke_Henry]

Alright, since I want to remove register_globals from my server, I am attempting to change over some code from the old session_is_registered stuff to the new $_SESSION stuff.

However, I have run into one snag that I cannot seem to fix.

Previously, when a user logged in, a built in function would perform session_is_registered on the $valid_user variable. I would then set the $valid_user variable to equal the username of the user. Then, I could retrieve the user's information from:

$result = mysql_query("select first_name, last_name, username from users where username='$valid_user'");
$row = mysql_fetch_assoc($result);
print("Logged in as $valid_user (" .$row["first_name"]. " " .$row["last_name"]. ") ");

Now, since I want to use $_SESSION, I have converted all of my code successfully except for this part (duplicated from above):

$result = mysql_query("select first_name, last_name, username from users where username='$valid_user'");

Basically, how do I replace the '$valid_user' reference with $_SESSION['valid_user'] ? I am not getting the syntax right.

Thanks

Why can't you just do this?

$result = mysql_query("select first_name, last_name, username from users where username='$_SESSION[\'valid_user\']'");

EDIT: ???? I've escaped the 's around valid_user with a \ but it doesn't show up... Oh well, here it is without the php tags:

$result = mysql_query("select first_name, last_name, username from users where username='$_SESSION[\'valid_user\']'");

EDIT: What the hell!? Lol well why can't you put a ' then $_SESSION[ then a \ before the ' then valid_user then a \ then ' then] then '");

Yes, thanks for your help.

I had the right syntax, I should have posted my new code. My problem was that I didn't have the { and } after my IF statement.

Thanks again, much appreciated.
