Question

我正在尝试创建一个注册页面。我按照指南但它的错误和我在运行它时出现了一个空白屏幕。我想我可能误解了一些代码。任何帮助将不胜感激。

<?php

        if (isset($_POST['register'])){
            if (empty($_POST['email']) &&
                (empty($_POST['username']) &&
                (empty($_POST['password']) &&
                (empty($_POST['re-enter']) &&
                (empty($_POST['title']) &&
                (empty($_POST['first name']) &&
                (empty($_POST['second name']) &&
                (empty($_POST['address']) &&
                (empty($_POST['postcode']) &&
                (empty($_POST['contactnumber'])){

您没有关闭＆＃39;（）＆＃39;在第二次，如果在所有评估中，你还有一个这样的＆＃39; [＆＃39;在$password=$_POST[['password'];

试试这个：

<?php

        if (isset($_POST['register'])){
            if ((empty($_POST['email'])) &&
                (empty($_POST['username'])) &&
                (empty($_POST['password'])) &&
                (empty($_POST['re-enter'])) &&
                (empty($_POST['title'])) &&
                (empty($_POST['first name'])) &&
                (empty($_POST['second name'])) &&
                (empty($_POST['address'])) &&
                (empty($_POST['postcode'])) &&
                (empty($_POST['contactnumber']))){
                    $email=$_POST['email'];
                    $username=$_POST['username'];
                    $password=$_POST['password'];
                    $reenter=$_POST['re-enter'];
                    $title=$_POST['title'];
                    $firstname=$_POST['firstname'];
                    $secondname=$_POST['secondname'];
                    $address=$_POST['address'];
                    $postcode=$_POST['postcode'];
                    $contactnum=$_POST['contactnumber'];
                    if ($password == $reenter) {
                        $conn = mysqli_connect('127.0.0.1', 'i7266***', 'Winter****', 'i72*****');
                        $emailquery = "SELECT * FROM UserTable WHERE email = '$email'";
                        $r = mysqli_query($conn, $emailquery);
                        $count = mysqli_num_rows($r);
                            if ($count == 1) {
                                echo "Email already exists";
                            } else {
                                $query = "INSERT INTO UserTable VALUES ('$username', '$password', '$email', '$title', '$firstname', '$secondname', '$address', '$postcode', '$contactnum')";
                                $run = mysqli_query($conn, $query);
                                echo "Customer account has been created";
                            }
                    } else {
                    echo "Passwords did not match";
                    } 
            } else {
                echo "please enter your details to register";
                }


        }else {
            echo "Please enter details to register";
            }



    ?>
    <form method="POST" action="">
    Email:
    <input type="email" name="email"><br>
    Username:
    <input type="text" name="username"><br>
    Password:
    <input type="password" name="password"><br>
    Re-enter password:
    <input type="password" name="re-enter"><br>
    Title:
    <input type="text" name="title"><br>
    First name:
    <input type="text" name="firstname"><br>
    Second name:
    <input type="text" name="secondname"><br>
    Address
    <input type="text" name="address"><br>
    Postcode:

希望对你有用。

现在语法很好，但逻辑是错误的，因为@Niet，Dark Absol说：只有当所有形式都为空时才处理表格。
