Create user login in PHPCreate members pages on your website within minutes with Member Login script. PHP is a good alternative when you decide to add a password protected web pages on your web site. You can also use htaccess password protection but with PHP you can create a lot more complex and configurable protection. In this example I will use SESSION variables for login verification. Lets start with building a configuration file for setting up all the username/password combinations. Create a new passwords.php file and add the following code in it. <?php $USERS["username1"] = "password1"; $USERS["username2"] = "password2"; $USERS["username3"] = "password3"; function check_logged(){ global $_SESSION, $USERS; if (!array_key_exists($_SESSION["logged"],$USERS)) { header("Location: login.php"); }; }; ?> Above code creates an $USER array with 3 username/password combinations. We also did a function which will be used later to check if an user is logged in or not. What we need now is a login page (called login.php) where users will enter their username and password and will login. <?php session_start(); include("passwords.php"); if ($_POST["ac"]=="log") { /// do after login form is submitted if ($USERS[$_POST["username"]]==$_POST["password"]) { /// check if submitted username and password exist in $USERS array $_SESSION["logged"]=$_POST["username"]; } else { echo 'Incorrect username/password. Please, try again.'; }; }; if (array_key_exists($_SESSION["logged"],$USERS)) { //// check if user is logged or not echo "You are logged in."; //// if user is logged show a message } else { //// if not logged show login form echo '<form action="login.php" method="post"><input type="hidden" name="ac" value="log"> '; echo 'Username: <input type="text" name="username" /><br />'; echo 'Password: <input type="password" name="password" /><br />'; echo '<input type="submit" value="Login" />'; echo '</form>'; }; ?> In order to use the user login feature for your PHP files you need to put that code at the very top of each of your PHP files that need to be protected. <?php session_start(); /// initialize session include("passwords.php"); check_logged(); /// function checks if visitor is logged. If user is not logged the user is redirected to login.php page ?> your page code goes here Create members pages on your website within minutes with Member Login script. COMMENTS

TJ Hemingway First off - thanks so much. I really am trying to make sense of this and I know I am getting close. If someone has a moment to look at my login and see if there is something obvious I am overlooking, I would be immensely grateful. The login/logout works but with warnings. http://www.tjhemingway.com/login.php . I have a passwords.php, login.php and logout.php. All are getting a header error of some sort. The redirect is not going to the respective pages. One of the pages I want it to redirect to is http://www.tjhemingway.com/proofs/AshleyH/index.php I am getting an error with that as well. I have tried all sorts of variations from previous postings but they don't seem to be working for me. Any assistance is welcomed!!
