register form in php just reloading same page
Question
I have a register page for users who can register using email, with email activation and Google captcha. My register code is as follows:
<?php require_once('connect.php'); include('config.php'); include('recaptchalib.php'); $response = null; $reCaptcha = new ReCaptcha($secret); if(isset($_POST) & !empty($_POST)){ if($_POST['g-recaptcha-response']){ $response = $reCaptcha->verifyResponse( $_SERVER['REMOTE_ADDR'], $_POST['g-recaptcha-response'] ); } if($response != null && $response->success){ $username = mysqli_real_escape_string($connection, $_POST['username']); $verification_key = md5($username); $email = mysqli_real_escape_string($connection, $_POST['email']); $password = md5($_POST['password']); $passwordagain = md5($_POST['passwordagain']); if($password == $passwordagain){ $fmsg = ""; $usernamesql = "SELECT * FROM `usermanagement` WHERE username='$username'"; $usernameres = mysqli_query($connection, $usernamesql); $count = mysqli_num_rows($usernameres); if($count == 1){ $fmsg .= "Username exists in Database, please try different user name"; } $emailsql = "SELECT * FROM `usermanagement` WHERE email='$email'"; $emailres = mysqli_query($connection, $emailsql); $emailcount = mysqli_num_rows($emailres); if($emailcount == 1){ $fmsg .= "Email exists in Database, please reset your password"; } echo $sql = "INSERT INTO `usermanagement` (username, email, password, verification_key) VALUES ('$username', '$email', '$password', '$verification_key')"; $result = mysqli_query($connection, $sql); if($result){ $smsg = "User Registered succesfully"; $id = mysqli_insert_id($connection); require 'PHPMailer/PHPMailerAutoload.php'; $mail = new PHPMailer; $mail->isSMTP(); $mail->Host = $smtphost; $mail->SMTPAuth = true; $mail->Username = $smtpuser; $mail->Password = $smtppass; $mail->SMTPSecure = 'ssl'; $mail->Port = 465; $mail->setFrom('admin@teia.website', 'BookTheParty'); $mail->addAddress('zubairoliyatofficial@gmail.com', 'Zubair Nazer'); $mail->Subject = 'Verify Your Email'; $mail->Body = "http://localhost/user-management/verify.php?key=$verification_key&id=$id"; $mail->AltBody = 'This is the body in plain text for non-HTML mail clients'; if(!$mail->send()) { echo 'Message could not be sent.'; echo 'Mailer Error: ' . $mail->ErrorInfo; } else { echo 'Message has been sent'; } }else{ $fmsg .= "Failed to register user"; } }else{ $fmsg = "Password not matching"; } } } ?> <html> <head> <title>User Registration Script in PHP & MySQL</title> <!-- Latest compiled and minified CSS --> <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" > <!-- Optional theme --> <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap-theme.min.css" > <link rel="stylesheet" href="styles.css" > <script src="https://code.jquery.com/jquery-3.1.1.js" ></script> <script src='https://www.google.com/recaptcha/api.js'></script> <!-- Latest compiled and minified JavaScript --> <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script> <script type="text/javascript"> $(document).ready(function() { $('#usernameLoading').hide();

?> </body> </html>
Now when the user tries to register, no error is showing and the values are not added to the database. Also, it's simply reloading the page. Can anyone please tell me whats wrong with my code?

The only thing that I've managed to spot is that you're trying to define a variable within an echo, when you do the insert. Try having '$sql' just by itself like below... hope this helps :)
<?php $sql = "INSERT INTO `usermanagement` (username, email, password, verification_key) VALUES ('$username', '$email', '$password', '$verification_key')"; $result = mysqli_query($connection, $sql); ?>
