Hey Alex. Not sure if you read these comments much, but I want thank you for these tutorials.

I had actually started PHP about half a year ago, and these tutorials were how I learnt the absolute basics. Now I'm very confident in my PHP programming and if I need to do something 90% of the time I'm able to visualise in my head how it's done without tutorials.

Not only is this a message to Alex but to the viewers - These are top standard tutorials, be sure to thank this guy for giving them all

PEOPLE!!!
IT WAS A GREAT TUTORIAL!
BUT WE'RE IN 2015 NOW, PLEASE LOOK AT NEWER TUTORIALS, A LOGIN SYSTEM IS QUITE SECURITY-CRITICAL AND THIS VIDEO IS FROM 2009!!!

1) the line $query = mysql_query("SELECT * FROM users WHERE username ='$username'"); is SQL-Injectable (please google SQL Injection)

2) When you get some input from the user, it must be considered dangerous and filtered to prevent XSS (Cross site scripting, a type of attack)

3) mysql_* functions are now deprecated, they shouldn't be used.

I "logged in" to my Youtube account to say "Thank you very much for this information."

I wish you more successes in your life.

Ok I fixed it.

I recommend Googling your errors to find out what your errors mean. Mine turned out to be a query error. Turns out the rows I had named within phpmyadmin were not the same as those I'd specified in my login.php document. Works a charm now, thank you!

Thank you Anixt. I actually got past this and moved on to another hurdle. This time, it is making it so a user cannot register with an "already used" user name.
