ryanmetzler3 Posted August 18, 2013 Share Posted August 18, 2013 I will show you my code real quick to start: Here is the registration form and script. <?php include ('config.php'); if ($_SERVER['REQUEST_METHOD'] == 'POST') { $username = mysql_real_escape_string($_POST['username']); $password = mysql_real_escape_string(md5($_POST['password'])); $firstname = mysql_real_escape_string($_POST['firstname']); $lastname = mysql_real_escape_string($_POST['lastname']); $email = mysql_real_escape_string($_POST['email']); if (empty($username)) { echo("You have to fill in an username!"); } else { if(empty($password)){ echo ("You have to fill in a password!"); } else { $query = mysql_query("SELECT * FROM users WHERE username = '$username'"); $rows = mysql_num_rows($query); } if ($rows > 0) { die("Username taken!"); } else { $user_input = mysql_query("INSERT INTO users (username, password, firstname, lastname, email) VALUES ('$username','$password','$firstname','$lastname','$email')"); echo("Succesfuly Registered!"); } } } ?> <html> <head> <title>Register</title> </head> <body> <form action="register.php" method="post"> First Name: <input type="text" name="firstname"><br/> Last Name: <input type="text" name="lastname" /><br/> Email: <input type="text" name="email" /><br/> Username: <input type="text" name="username" /><br/> Password: <input type="password" name="password"/><br/> <input type="submit" value="Register!"/> </form> </body> </html> Here is the login form and script: <?php include ("config.php"); if ($_SERVER['REQUEST_METHOD'] == 'POST') { $username = mysql_real_escape_string($_POST['username']); $password = mysql_real_escape_string(md5($_POST['password'])); $query = mysql_query("SELECT * FROM users WHERE username='$username' AND password='$password'"); $query_rows = mysql_num_rows($query); if($query_rows > 0) { $user_data = mysql_fetch_array($query); echo ("Succesfull Login!"); session_start(); $_SESSION['user'] = "$user_data"; } else { echo ("Username and/or password incorrect"); } } if (isset($_SESSION['user'])) { echo "Welcome {$_SESSION['user']['username']}"; } ?> <html> <head> <title>Login</title> </head> <body> <form action="login.php" method="post"> Username: <input type="text" name="username" /><br/> Password: <input type="password" name="password"/><br/> <input type="submit" value="Login!"/> </form> </body> </html> I am having two problems. When I hit login the very last if statement from the login code is supposed to echo a welcome message back out to the user with their username. But no matter the username it always just says "Welcome A". I am totally stumped on that. That is my first question. Here is my other general question. Here is my site s-w-a-p-e-z-e-e(dot)com (take the junk out, I just don't want this showing up in search engines). When a person logs in I hope to be able to display their username above the picture in the top right of my site pages. Also when they upload a photo I want their username to be injected into the database with their photo. I am guessing you need to use sessions to do this. I am teaching myself to program so be kind haha. Thanks so much anyone who can help! Quote Link to comment Share on other sites More sharing options...
PravinS Posted August 20, 2013 Share Posted August 20, 2013 session_start() function should be at the top every time Quote Link to comment Share on other sites More sharing options...
