表单输入未显示在 form.php 页面上，并且否定了我的表单验证。该错误表示我在 form.php 上的所有变量的未定义变量。请告诉我我必须在我的代码中编辑什么以使其在 form.php 上显示表单输入。当我在同一页面上使用它时它可以工作，但我宁愿它显示在另一个页面上。

编辑

到目前为止，谢谢，但我无法获得复选框的值，即收件人（管理员或内容编辑器），以显示它显示“数组”或“A”。

问题是当你header("Location:")，form.php所有的POST价值都丢失了。您必须使用标头重新发送它们，或者将它们修改为GET并再次检索它们。将它们（contact.php 和 form.php）放在一个页面中应该更有效。这样，表单数据只需发送一次。

您可以像这样将 POST 值作为 GET 发送到 form.php。

联系方式.php：

header("Location: form.php?name=".$name."&email=".$email."&subject=".$subject."&message=".$message);

form.php（检索值）：

$name = $_GET['name'];
$email = $_GET['email'];
$message = $_GET['message'];
$subject = $_GET['subject'];

如果您想将数据传输contact.php到form.php您应该使用以下内容：

联系人.php

$data = urlencode(
        serialize(
             array(
                   "name" => $name, 
                   "email" => $email,
                   "subject" => $subject,
                   "message" => $message)
                  ));

header('Location: form.php?data=' . $data);

表单.php

$data = unserialize(urldecode($_GET['data']));

$name = $data["name"];
$email = $data["email"];
$subject = $data["subject"];
$message = $data["message"];

这会序列化数据数组，contact.php然后 URL 对其进行编码并将其作为 GET 变量发送到form.php. 之后，form.phpURL 对数据进行解码和反序列化以供使用。

如果要显示表单元素，则必须使用这种方法。

<form method="POST" action="contact.php">
Email<input type="text" name="email">
.......
.......
.......
// All elements
</form>

这可能会对您有所帮助。
