Question

我有一个注册页面，供可以使用电子邮件进行注册，激活电子邮件和Google验证码的用户使用。我的注册代码如下：

<?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";
		}
	}
}
?>

      </form>
</div>
<?php require_once('credits.php'); ?>
</body>
</html>

现在，当用户尝试注册时，没有错误显示，并且值未添加到数据库中。另外，它只是重新加载页面。谁能告诉我我的代码有什么问题吗？

我设法发现的唯一一件事是，当您执行插入操作时，您正在尝试在回显中定义一个变量。尝试像下面这样单独使用'$ sql'...希望这会有所帮助：）

<?php 
$sql = "INSERT INTO `usermanagement` (username, email, password, verification_key) VALUES ('$username', '$email', '$password', '$verification_key')";

$result = mysqli_query($connection, $sql);
	?>

在php中注册表格，只需重新加载同一页面
