trq Posted April 29, 2014 Share Posted April 29, 2014 Seriously, there must be already hundreds of tutorials on this subject. Do you want use to write another one just for you? How about, you try an existing one and come and ask a specific question when/if you get stuck.

denno020 Posted April 29, 2014 Share Posted April 29, 2014 You need to call session_start() at the top of every script that you wish to be 'login protected', so because of that, yes, you need to include init.php on every page. To check if a user is signed in, set a session array value with their username. Then at the start of each of your pages, check the session array, if the username value is set, (optionally) check that that username corresponds to a user in your database, and if so, you can show them the content that only logged in users can see.

Jacques1 Posted April 29, 2014 Share Posted April 29, 2014 Hi, “doesn't work” isn't very useful as a problem description. What is the problem? Are you getting an error message? An unexpected result? The infamous white screen? Something else? You need to tell us, because we can't see your screen from here. Either way, the code has a couple of serious issues: Plaintext passwords? Seriously? Even if you don't give a damn about the website, that's just unacceptable. You need to hash the passwords with a strong algorithm like bcrypt. If you have PHP 5.5, the functions are already built into the language. Otherwise, there's a compatibility library. What is this weird strip_tags() doing there? It makes absolutely no sense. It's actually downright harmful, because it mangles the user input. If the user chooses, say, "2$<53Ab!.-" as their password, your strip_tags() truncates it to "2$", because it happens to have a "<" in it. Oops. Why on earth do you put the passwords in the session? Shouldn't you protect them rather then throwing them around? The plaintext passwords don't go anywhere. You store a hash of them in the database, and that's it. Do not put them into the session, a cookie or whatever. The mysql_* functions you're using are obsolete since more than 10 years and will be removed in the future. Nowadays, we use PDO or MySQLi.

sKunKbad Posted April 29, 2014 Share Posted April 29, 2014 (edited) There is really nothing simple about an effective, safe, and trustworthy authentication script / class. Having spent hundreds of hours on my own, I can tell you that you aren't going to get a final product worth using unless you have great dedication. Your best option is to pick up a framework that already has an Auth class.

trq Posted April 29, 2014 Share Posted April 29, 2014 Am I wrong, or does this script not even check the password? I see where your SQL checks the email address, but not the password. The password is checked in the query.
