我无法弄清楚为什么无论如何地址和城市字段对我来说总是空的。我输入任何基本数据，将其发布并到达另一边，它说它是空的。有什么明显的我做错了吗？提前致谢。

这就是我获取通过 post 传递的值的方式：

$username = $_POST['username'];
$password = $_POST['password'];
$email = $_POST['email'];
$fname = $_POST['fname'];
$lname = $_POST['lname'];
$phone = $_POST['phone'];
$address_one = $_POST['address_one'];
$address_two = $_POST['address_two'];
$city = $_POST['city'];
$age = $_POST['age'];

我用来收集数据的表格：

 <form id='login' action='createreg.php' method='post' accept-charset='UTF-8'>
                <h3>Create an Account</h3>
                <table id='registertb'>

                    <tr>
                        <td>Username:</td>
                        <td>
                        <input type='text' name='username' id='username' class='loginfield' maxlength="50" />
                        </td>
                    </tr>
                    <tr>
                        <td>Password:</td>
                        <td>
                        <input type='password' name='password' id='password' class='loginfield' maxlength="50" />
                        </td>
                    </tr>
                    <tr>
                        <td>Email:</td>
                        <td>
                        <input type='text' name='email' id='email' class='loginfield' maxlength="50" />
                        </td>
                    </tr>
                    <tr>
                        <td>First Name:</td>
                        <td>

                    </tr>
                    <tr>

您错误地命名了您的输入。在您的 PHP 中，您可以使用这些来设置变量：

$address_one = $_POST['address_one'];
$address_two = $_POST['address_two'];
$city = $_POST['city'];

但是 HTML 按数字引用地址字段，而城市输入实际上是address2. 您需要设置输入name属性以匹配您在$_POST变量中使用的内容。
