In this advanced tutorial i will teach you the steps required to create a custom build login/member system with PHP.

The system itself ofcourse has alot of room for improvements, also, it’s very easily expandable, i’ve chosen to work in a modular way, so that if you change something you only have to change it in 1 file. I’ve done this by using functions, this script is a good example of the real power of PHP.

Features:

  • Registration
  • Lost password
  • Various checks on passwords and usernames
  • users can change their password
  • Passwords are stored in a database with a seed added to it and they have sha1 encryption
  • Easy to adjust & use

Requirements:

  • Mysql database
  • a php & mysql enabled host
  • php mail() enabled host
  • ftp access to your website

Overview

Steps:

  1. Creating the mysql table
  2. Creating a db_connect.inc.php file
  3. Creating the header.php file
  4. Creating the footer.php file
  5. Creating the index.php file
  6. Creating the login.php file
  7. Creating the logout.php file
  8. Creating a function.inc.php file
  9. Creating the mail.functions.inc.php file
  10. Creating the display.functions.inc.php file
  11. Creating the login.functions.inc.php file
  12. Creating the user.functions.inc.php file
  13. Creating the validation.functions.inc.php file
  14. Creating the lostpassword.php file
  15. Creating the changepassword.php file
  16. Creating the register.php file
  17. Creating the activate.php file

Step 1: Creating the mysql table

For this tutorials i presume you already know how to add tables to your database.

Table login (SQL code):

CREATE TABLE  `login` (
  `loginid` int(10) unsigned NOT NULL auto_increment,
  `username` varchar(30) NOT NULL,
  `password` varchar(50) NOT NULL,
  `email` varchar(255) NOT NULL,
  `actcode` varchar(45) NOT NULL,
  `disabled` tinyint(1) NOT NULL default '0',
  `activated` tinyint(1) NOT NULL default '0',
  PRIMARY KEY  (`loginid`)
);

Now let us add the administrator account:

  • username: admin
  • password: yourpasswordhere

** Change the text yourpassword here with the desired password.

** Change the text youremailhere with your email adress.

SQL query:

?View Code SQL

insert into login (username,password,email,activated) value ('admin',sha1(concat('yourpasswordhere','0dAfghRqSTgx')),'youremailhere','1');

The table is now ready, and the administrator account has been added. let us move on to step 2.

Step 2: Creating a db_connect.inc.php file

This file will be used to manage the connection to the database.

File db_connect.inc.php:

<?php
// Database settings
// database hostname or IP. default:localhost
// localhost will be correct for 99% of times
define("HOST", "localhost");
// Database user
define("DBUSER", "dbuser");
// Database password
define("PASS", "dbpass");
// Database name
define("DB", "dbname");
 
############## Make the mysql connection ###########
$conn = mysql_connect(HOST, DBUSER, PASS) or  die('Could not connect !<br />Please contact the site\'s administrator.');
 
$db = mysql_select_db(DB) or  die('Could not connect to database !<br />Please contact the site\'s administrator.');
 
?>

Let me explain:

  • HOST: this is the location for the database server it can be a hostname or an ip adress. it is usualy localhost.
  • DBUSER: this is the database user account used to access the database.
  • PASS: this is the password for the database user account.
  • DB: this is the name of the database used.

Step 3: Creating the header.php file

File header.php:

<?php
error_reporting(0); // we don't want to see errors on screen
// Start a session
session_start();
require_once ('db_connect.inc.php'); // include the database connection
require_once ("functions.inc.php"); // include all the functions
$seed="0dAfghRqSTgx"; // the seed for the passwords
$domain =  "ineedtutorials.com"; // the domain name without http://www.
 
?>

<title>Complete Member Login / System tutorial - <?php echo $domain; ?></title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
</head>
<body>

Step 4: Creating the footer.php file

The footer file is included at the bottom of every page, it looks like this:

<hr>
<div id='footer'>Copyright 2007-2008 &copy; <?php echo $domain; ?></div>
</body>
</html>

Step 5: Creating the index.php file

In this step we will create the homepage of the website, we’ll keep it very basic, only the login will be displayed.

File index.php:

<?php 
 
 require_once "header.php"; 
 //content
 include "login.php";
 // more content
 require_once "footer.php";
 
?>

Step 6: Creating the login.php file

In this step we will make the actual login page, because we want to keep it readable we create some custom build functions that will handle the actual login. So basicly all this page will do is call the functions checkLogin(), show_loginform() and isLoggedIn()

<?php
if (!isLoggedIn())
{
    // user is not logged in.
    if (isset($_POST['cmdlogin']))
    {
        // retrieve the username and password sent from login form & check the login.
        if (checkLogin($_POST['username'], $_POST['password']))
        {
            show_userbox();
        } else
        {
            echo "Incorrect Login information !";
            show_loginform();
        }
    } else
    {
        // User is not logged in and has not pressed the login button
        // so we show him the loginform
        show_loginform();
    }
 
} else
{
    // The user is already loggedin, so we show the userbox.
    show_userbox();
}
?>

Step 7: Creating the logout.php file

The logout file will destroy the session and it’s stored information. Afterwards it will redirect the user to the homepage.

File logout.php:

<?php 
session_start();
if( session_unregister('loginid') == true && session_unregister('username')==true ) {
    session_destroy();
	header('Location: index.php');
  } else {
   unset($_SESSION['loginid']);
   unset($_SESSION['username']);
   session_destroy();
   header('Location: index.php');
}
?>

Step 8: Creating the function.inc.php file

Now we will create a file that will store all our functions, by including this file all our functions will be accessable.
It will help keep track of your functions.

File functions.inc.php:

require_once("user.functions.inc.php");
require_once("display.functions.inc.php");
require_once("login.functions.inc.php");
require_once("validation.functions.inc.php");
 
 
function generate_code($length = 10)
{
 
    if ($length <= 0)
    {
        return false;
    }
 
    $code = "";
    $chars = "abcdefghijklmnpqrstuvwxyzABCDEFGHIJKLMNPQRSTUVWXYZ123456789";
    srand((double)microtime() * 1000000);
    for ($i = 0; $i < $length; $i++)
    {
        $code = $code . substr($chars, rand() % strlen($chars), 1);
    }
    return $code;
 
}
 
?>

Step 9: Creating the mail.functions.inc.php file

This file will contain all functions that we use to send emails.

function sendLostPasswordEmail($username, $email, $newpassword)
{
 
    global $domain;
    $message = "
You have requested a new password on http://www.$domain/,
 
Your new password information:
 
username:  $username
password:  $newpassword
 
 
Regards
$domain Administration
";
 
    if (sendMail($email, "Your password has been reset.", $message, "no-reply@$domain"))
    {
        return true;
    } else
    {
        return false;
    }
 
 
}
 
function sendMail($to, $subject, $message, $from)
{
 
 
    $from_header = "From: $from";
 
    if (mail($to, $subject, $message, $from_header))
    {
        return true;
    } else
    {
        return false;
    }
    return false;
}
 
function sendActivationEmail($username, $password, $uid, $email, $actcode)
{
    global $domain;
    $link = "http://www.$domain/activate.php?uid=$uid&actcode=$actcode";
    $message = "
Thank you for registering on http://www.$domain/,
 
Your account information:
 
username:  $username
password:  $password
 
Please click the link below to activate your account.
 
$link
 
Regards

";
 
    if (sendMail($email, "Please activate your account.", $message, "no-reply@$domain"))
    {
        return true;
    } else
    {
        return false;
    }
}
 
?>

Step 10: Creating the display.functions.inc.php file

This file will contain all functions that display a form or a userbox on the page.

For example: It contains the loginform, the HTML code for the userbox, the lostpassword form, …

file: display.functions.inc.php

    When I login and click the changepassword link, I get the login form because there is no sessions. Why? I’m using php tables, so I get a url like index.php?action=changepw

    hi firstly what an awesome tutorial thankies!
    im implementing this into my content management system and the register/login process works fantastically - the only problem is that I’m testing locallly and the Activation email never gets sent …
    however, the record does exist in the database and the login is functional once you register the details …
    can you elaborate on Step 9 - Creating the mail.functions.inc.php file:
    how can I get the Activation Email working?
    Thanks!

    This would be a much better script when it should be build on the zend framework.

    mysql_ is not developed further anymore and mysqli and pdo are both in the Zend Framework.

    There is a major security bug in the change password form… you could just make your own HTML file and change the value of the user name and change anyones password…

    I’m getting that annoying “No input file specified.” message when I try to activate. I’ve done error checking and looked for mistakes in file names but I’m not finding anything. Anyone know what might be causing it?

    I know that the message “No input file specified.” comes up sometimes because of the way PHP is set up on the server. I have no access to change anything like that so other suggestions would be VERY appreciated.
    <?php
    require_once “header.php”;
    $uid = (int)htmlentities(strip_tags($_GET['uid']));
    $actcode = htmlentities(strip_tags($_GET['actcode']));
    if (activateUser($uid, $actcode) == true)
    {
    echo “Thank you for activating your account, You can now login.
    Click here to login.“;
    } else
    {
    echo “Activation failed! Please try again.”;
    echo “If problem persists please contact the webmaster.”;
    }
    require_once “footer.php”;
    ?>

    Thanks!

    hey if you are getting the clank page error make sure you named the functions.inc.php as functions.inc.php and NOT function.inc.php.

    hey if you are getting the blank page error make sure you named the functions.inc.php as functions.inc.php and NOT function.inc.php. Also make sure all your other files are there and have the correct names. The only one that was messed up is the functions.inc.php.

    Also for those of you getting the login error make sure you are putting the correct case. It is case sensitive.

    Hi I know this may seem stupid but ive everything done but not sure what values to use for DB, HOST, DBUSER and PASS. I know my DB is the actual database name and HOST is localhost but do I use the admin name and password for the rest? Whenever I go onto index.php i get the error :

    Could not connect!
    Please contact the site’s administrator.

    I have figured out that the problem is in this line of code in the db_connect.inc.php:
    $conn = mysql_connect(HOST, DBUSER, PASS) or die(’Could not connect fdg!Please contact the site\’s administrator.’);
    ….if thats any help! I cant figure out how to actually get this working if someone could help me I would appreciate it so much!!!
