When I try to sign in to the registration system I fill all the fields and I get this error: "User could not be added to the database!" I don't know what I did wrong. I created a database named "users" on phpmyadmin and I created a table with the same name where I set up the id, the username, the password and the avatar. Then I wrote this php script: <?php session_start(); $_SESSION['message'] = ''; $mysqli = new mysqli("localhost", "root", "mypass123", "users"); //the form has been submitted with post if ($_SERVER["REQUEST_METHOD"] == "POST") { //two passwords are equal to each other if ($_POST['password'] == $_POST['confirmpassword']) { //set all the post variables $username = $mysqli->real_escape_string($_POST['username']); $email = $mysqli->real_escape_string($_POST['email']); $password = md5($_POST['password']); //md5 has password for security $avatar_path = $mysqli->real_escape_string('images/'.$_FILES['avatar']['name']); //make sure the file type is image if (preg_match("!image!",$_FILES['avatar']['type'])) { //copy image to images/ folder if (copy($_FILES['avatar']['tmp_name'], $avatar_path)){ //set session variables $_SESSION['username'] = $username; $_SESSION['avatar'] = $avatar_path; //insert user data into database $sql = "INSERT INTO users (username, email, password, avatar) " . "VALUES ('$username', '$email', '$password', '$avatar_path')"; //if the query is successsful, redirect to welcome.php page, done! if ($mysqli->query($sql) === true){ $_SESSION['message'] = "Registration succesful! Added $username to the database!"; header("location: welcome.php"); } else { $_SESSION['message'] = 'User could not be added to the database!'; } $mysqli->close(); } else { $_SESSION['message'] = 'File upload failed!'; } } else { $_SESSION['message'] = 'Please only upload GIF, JPG or PNG images!'; } } else { $_SESSION['message'] = 'Two passwords do not match!'; } } ?> <link href="//db.onlinewebfonts.com/c/a4e256ed67403c6ad5d43937ed48a77b?family=Core+Sans+N+W01+35+Light" rel="stylesheet" type="text/css"/> <link rel="stylesheet" href="form.css" type="text/css"> <div class="body-content"> <div class="module"> <h1>Create an account</h1> <form class="form" action="form.php" method="post" enctype="multipart/form-data" autocomplete="off"> <div class="alert alert-error"><?= $_SESSION['message'] ?></div> <input type="text" placeholder="User Name" name="username" required /> <input type="email" placeholder="Email" name="email" required /> <input type="password" placeholder="Password" name="password" autocomplete="new-password" required /> <input type="password" placeholder="Confirm Password" name="confirmpassword" autocomplete="new-password" required /> <div class="avatar"><label>Select your avatar: </label><input type="file" name="avatar" accept="image/*" required /></div> <input type="submit" value="Register" name="register" class="btn btn-block btn-primary" /> </form> </div> </div> What did I do wrong?
Nevermind, I'm tired woo! I didn't create the email field on phpmyadmin and that's why I got the error. Everything works fine now! Thanks anyway.
