I developing a new site and its the first time im having a user login..
Ive been menaing to understand sessions for a while...
Ive managed to set a cookie with the user deatils when they login, this also gives a unique logcode. that rights to the database everytie the user logs in..but i dont what to do with it or wether I need it all.
Ive but lookin at sessions but i cant get the to work on my local machine (runnng apache and obviously php,, n mysql..).
ive been looking for a good php seesions tutorial but cant seem to find a good one,, found one a t hot scripts but it didnt seem to be right..
ne way can you help out?
why do not you try your experimentations from the server.
You mentioned hotscripts
Do not look only for sessions but look for authentication scripts
Apache, MySQL and PHP be advised that sessions will not work from a PC MS environment
I've set up Apache, MySQL and PHP using the firepages installer on a Win98 and a WinXP machine and I've had no problems with sessions.
Zend has some good tutorials. Here's the one on sessions [zend.com].
second what henry says about using authentification scripts.
i've just started user patUser on bits of my site and it's relatively easy to implement and copes with anything i can dream of. it is simply a class which manages user logins, etc.
you'll learn a lot about sessions just from implementing it - good luck ;-)
will try my scripts on my online server see if they work..
can anyone see what is wrong with my scripts?
part of my login.php script
//intitiate session
session_start();
//register some seesion variables
session_register("SESSION");
//including the username
session_register("SESSION_USERNAME");
$SESSION_USERNAME = $username;
part of the page i want to be protected
(I commented out the session start as it didnt work with it in.)
//session_start();
if (!session_is_registered("SESSION"))
{
//if session check fails, invoke error handler
print "your not logged in";
}
else
{
//display results
print "<html>
<head</head>
<body>
</body>
</html>
";
}
part of my login.php script
//intitiate session
session_start();
YES, what's wrong is when you are using SESSIONS the very first line of code (WITH NO EXCEPTIONS!) MUST BE
<?php session_start();?>
there can be no spaces before the opening php tag either. this is the header that MUST BE SEND first
$_SESSION['foo']= 'bar'; Minor addition to zeebart's post: make sure that session_start() comes before any output is sent to the browser (headers, cookies, text, whatever). It is however quite OK to do other stuff first, like database queries.
