  1. Mate are you fucking joking? Thanks for making this video and all, I'm sure the code works fine, but you can't just make a video, say 'see you in part 2' and then not have a part 2…

    I, as a novice php programmer just took 1 hour out of my day to follow this tutorial, and now have almost 200 lines of code which mean absolutely NOTHING to me…

  2. I understand, would be great if you could. Im trying to master the login and reg using OOP style programming. I found the first video very helpful. I had to tweak it a bit to make it work but it is very directional.

    Thanks for your response

    Regards

  10. Hello Brandon that for the tutorial but I just have one problem when I go in the SQL code area of the local host  and input the code that you gave to us on you tube I get a error that says this MySQL sever version for the right syntax to use near 'CREATE TABLE KV_PENDING(USER_ID INTEGER UNSIGNED NOT NULL, TOKEN CHAR(10) N' at line 14. Brandon I'm using Xampp v3.2.1 so I think I'll need to find the right syntax to put near CREATE TABLE KV_PENDING etc…. Can you help me find the right state there.

    Thanks Tony D.

  22. Fantastic video and a great introduction to object orientated programming. I do have a few questions though…excuse me for being a noob! Basically does it matter what version of php you are running or its compiler, as I keep getting a error for all the the lines that start with public function __ for example: public function __set it really doesn't like and comes up with this error: "Parse error: syntax error, unexpected 'public' (T_PUBLIC) in C:xampphtdocsocsopsuser.php on line 35".

  23. Thanls for the vid, im getting an Parse error: syntax error, unexpected 'public' (T_PUBLIC) in C:xampphtdocsUser.php on line 33, at line 33 in my code its : //return if username if valid format
    public static function validateUsername($username){
    return preg_match('/^[A-Z0-9]{2,20}$/i', $username);

    }

    Any suggestions?????

  26. Will be creating the next tutorial within a weeks time. Just been pretty busy lately, Mic is super sensitive so It has to be extremely quiet in my house lol. I apologize for the wait.
