The first part is here: User Authentication along with all the files you need. The first script to take a look at in your login folder is login.php. Open up this script in a text editor, and well see how it works. Of course, you can fire up your server and error message try it out. What you'll see is a simple login page with textboxes for username and password, as well as a submit button. It will look like this: The HTML for this form can be seen at the bottom of the login.php script that you have (hopefully) by now opened. There's nothing special about it. But notice that there's a PHP print statement in the login error message HTML Body section: This is for displaying error messages for the user. The first few line of the script, though, just set up some variables: $uname = ""; $pword = ""; $errorMessage = ""; $num_rows = 0; The $errorMessage variable is an important one. We'll add something to this variable, if an error occurs. We'll then check to see if it's blank or not. The next part of the code is just the SQL checking function you met earlier. This aims to prevent SQL injection attacks. After this code, we check to see if the form has been POSTED or not (was the Submit button clicked): if ($_SERVER['REQUEST_METHOD'] == 'POST') { } Most of our code goes between the curly brackets of this if statement. The first thing to do is to get the username and password from the textboxes: $uname = $_POST['username']; $pword = $_POST['password']; We then deal with any unwanted HTML (scripting attacks): $uname = htmlspecialchars($uname); $pword = htmlspecialchars($pword); Next, we attempt to connect to the database: $user_name = "root"; $pass_word = ""; $database = "login"; $server = "127.0.0.1"; $db_handle = mysql_connect($server, $user_name, $pass_word); $db_found =
