Question

我正在尝试将记录插入表中，但我在isset函数上遇到问题。我无法处理代码。

在以下代码中执行else语句而不是isset函数。

 <?php
if (isset($_POST['submit'])) {

    include_once 'dbh.inc.php';

    $firstname = mysqli_real_escape_string($conn, $_POST['firstname']);
    $surname = mysqli_real_escape_string($conn, $_POST['surname']);
    $email = mysqli_real_escape_string($conn, $_POST['email']);
    $username = mysqli_real_escape_string($conn, $_POST['username']);
    $password = mysqli_real_escape_string($conn, $_POST['password']);
    $cpassword = mysqli_real_escape_string($conn, $_POST['cpassword']);
    $bdate = mysqli_real_escape_string($conn, $_POST['bdate']);
    $gender = mysqli_real_escape_string($conn, $_POST['gender']);

    if(empty($firstname) || empty($surname) || empty($email) || empty($username) || empty($password) || empty($cpassword) || empty($bdate) || empty($gender)) {
       header("Location: ../index.php?index=empty");
       exit();
    } else {
        $sql = "SELECT * FROM users WHERE username='$username'";
        $result = mysqli_query($conn,$sql);
        $resultCheck = mysqli_num_rows($result);
        if ($resultCheck > 0) {
            header("Location: ../index.php?index=username already taken");
            exit();
        } else {
            // Hashing the password
            $hashedPassword = password_hash($password, PASSWORD_DEFAULT);
            //Insert users into the database
            $sql = "INSERT INTO users (id, firstname, surname, email, username, password, bdate, gender) VALUES ('', '$firstname', '$surname', '$email', '$username', '$password', '$bdate', '$gender');";
            mysqli_query($conn, $sql);
            header("Location: ../profile.php");
            exit();
        }
    }
} else {
    header("Location: ../index.php?index=error");
    exit();
}

这是包含“注册”部分的前端：

  <div class="row">
    <div class="col-lg-6 pull-right">
 <div class="panel panel-default">
  <div class="panel-heading">

Answer 1

您错过了按钮类型属性type="submit"如果您未包含此类型属性，则表单将不会提交数据。

您的代码：

<button class="btn btn-success" name="submit">Create Account</button>

应该是：

<button type="submit" class="btn btn-success" name="submit">Create Account</button>

如果，这不是你的问题，请告诉我！感谢。
