PHP Login Page Example.

Very useful post.
Thanks

thanks :)

Bien!!!

Your session checking not very secure.

Thanks! Very helpful!

A few hints:
– Using addslashes() for escaping is bad practice
– Storing passwords unencrypted is bad practice
– session_register() is deprecated
– A valid location headers require a full URL
– lock.php makes no sense. The existence of a username and / or user ID in the session is sufficient, if the authentication was done properly. (Unless you want to check for every single request if a user account has been disabled or deleted.)

something is one word

As Anonymous said, it's not good practice to store user passwords in a database in cleartext.

go to this site they have a tutorial on how to creat a simple login registration php

http://dudes-online.zxq.net/viewtopic.php?f=2&t=2

Plain text pass-wording != good idea. Use MD5 (varchar[32]) or SHA1 (varchar[40])

THank You very much
It really helped

why you place double check is it neccessary on that place . on welcome page include. instead of that placing if(!$_SESSION['login_user']):
gogto login page

good! good!

guys can you please help me with this error??

@yu You need to create a database and use the username and password you used for that to connect to the database. Just using what is already there won't do anything as you found out (unless you did use the username root and password yes)

1. don't store passwords, use an md5 hash or better
2. salt passwords before you create the hash
3. store users, salt and password in different tables, where only a limited php page and limited mysql user can verify the login
4. validate input always, unless its trusted
5. use mysql procedures for ckecking user
6. encrypt salt, note that this is ok but almost useless
7. if your brave, and have a good memory, use 100% unique sql tables and fields..i.e.
zu53Rs, xP4s5w0rds, y541ts
zuSERs, xPAsSwOrds, ySAlts

Not a bad little login example. Most examples don't use SESSIONS. Your example isn't perfect, but with a few tweaks it isn't bad now.

1) You should encrypt passwords.

2) On a few of the php files, the session_start() was not the FIRST line of code. Thus causing a error entry in the error_log. So ensure session_start(); is the VERY VERY VERY first line of code in each file that it is in!

3) Also, another minor error creating an entry in error_log. It is because on when a user isn't logged in, the session variable is null/nothing/empty... And you don't check if it is empty, you just assume there is a value and perform a database query with an empty username.

Lock.php:

session_start();
if(!isset($_SESSION['login_user'])){
header("location:login.php");

thanks

there is an error on the first line of login.php - youve writetn >?php instead of <?php

thanks for the sample login program...

it helped to anlyze where i went wrong..

thanks again.. im adding your site to ma favourite list.. keep up the good work buddy...:)

thanks...

Deprecated: Function session_register() is deprecated in C:\wamp\www\Project1\Login.php on line 25

this code is very useful for all php programmers...

Thanx for the useful tip

I am a little confused on the if ($count) statement

you set it equal to 1 but my count never is = 1 so it always just displays the ERROR msg.
What do you mean when you say table row must be 1 row??

good

Notice: Undefined index: active in C:\wamp\www\login.php on line 17

Fatal error: Call to undefined function session_register() in C:\wamp\www\login.php on line 25

Thanks for this, helped me to understand sessions better.

Anyone wanting to store the passwords in an MD5 can so so easily by firstly ensuring the passwords are MD5 in the database (store it in a VARCHAR) and then simply add $mypassword=md5($mypassword); under $mypassword=addslashes($_POST['password']);

Easy

nice code
