PHP代码未与html连接[重复]

Question

我很难让我的 PHP 和 HTML 在电子邮件表单上协同工作。这是我采用的一个网站，我不确定我错过了什么。我基本上是在模式中构建一个表单，因此用户必须在下载资产之前注册他们的电子邮件。因此，一旦发送了表单，他们就可以连接到下一页以下载他们需要的内容。我遇到的麻烦是表格。无论我尝试什么都行不通。救命！

Answer 1

您的表单有method="get"，并且您的 php 逻辑期待 POST 数据，因为您是通过 get 提交的，所以该数据永远不会设置。

将表单更改为 method="POST"。

<form name="send_form_email" action="../quform/send_form_email.php" method="POST" enctype="multipart/form-data">

Answer 2

您的表单在 get 中发送数据，但在 php 端您正在等待从 POST 获取数据，更改表单的 method 以使其工作。 应该是method="POST" 此外，您还有多个 email 输入（它们具有相同的名称）。 而且您没有收到来自此表单的$human = $_POST['human']; 和$subject = $_POST['3D Model Request'];
