Creating login/registration forms with php

[Shina Memud]

Hi everyone,

I love this forum and I am new to PHP, I am currently using Mysql for my database and I am the form (provided here) in my PHP and everything is working fine.

My problem is...I keep getting this message below but everything seems to be working.


Notice: Undefined index: loging in C:\xampp\htdocs\training2\index.php on line 36

Notice: Undefined index: userlogin in C:\xampp\htdocs\training2\index.php on line 72

Notice: Undefined index: password in C:\xampp\htdocs\training2\index.php on line 72
wrong password or username, please try again

Maybe I need to remove something or...not sure. Any info will be very helpful.

On the login page you seemed to have logging spelt wrong, as well userlogin and password were not sent correctly to it.

I changed that and it gave me the same ..


Notice: Undefined index: logging in C:\xampp\htdocs\training2\index.php on line 36

As for the userlogin and password, what can I do to make it send correctly?

So I downloaded your tutorial and I am trying to implement into a site I am building. However, when I register I am getting an error. Am I supposed to include:

CREATE TABLE `test`.`users` (
`id` INT NOT NULL auto_increment ,
`name` VARCHAR( 20 ) NOT NULL ,
`password` VARCHAR( 20 ) NOT NULL ,
`email` VARCHAR( 20 ) NOT NULL ,
PRIMARY KEY ( `id` )
)


And if so, where do I put this mySql code? Thanks.

This is the error I keep getting. Any thoughts?

Warning: mysql_connect() [function.mysql-connect]: Access denied for user 'root'@'localhost' (using password: NO) in /home/lizette/public_html/Time4Moore.com/DEV/register.php on line 10
Access denied for user 'root'@'localhost' (using password: NO)

This is a decent start but far from finished or good enough to be used in a live environment....

Why is the password sent in raw form?
Why are you using GET for authentication? This is against all web standards...
Proper PHP would be to use

$_GET['userlogin'] 

instead of

$_GET[userlogin] 

(although $_GET is the wrong method to use as $_POST is the proper).
Your MySQL is open to injection...
The session is vulnerable to session hijacking and fixation.
The database stores the raw password?!?!?! This is considered bad practice (although some would argue this) and the method used in this script is a textbook example of bad password practices. If you insist on storing the password in it;s raw form, you should not use it as an authentication but instead validate a hash of their password against another hash in the db.. never send raw passwords and never compare against a raw password in the db...

The majority of the errors you are getting are because

$_GET[userlogin] 

should be

$_GET['userlogin'] 

(note the ' wrapping the key).
Update all the array keys to use the ' and your errors will go away.
Also, the session check will throw an error too for first time users.

if($_SESSION["logged"]) 

should also be

if(isset($_SESSION["logged"]) && ($_SESSION["logged"] === true) ) 

Please note that this login script is not good to use on a live site unless you don't care about people gaining access to it or seeing you raw password.
