php 表单不发送提交数据。但是仍然发送电子邮件和处理表格

Question

我的网站上有两个表格。一个工作正常，另一个使用 email_from: 等发送电子邮件，但不捕获任何表单数据。

想知道它可能是什么。如果这有助于调试，我也可以发布与它一起工作的 html 表单。非常新手和使用堆栈溢出/其他站点的构建形式。

这里是php

<?php

if(isset($_POST ['submit'])) 

{

 $coffee = ($_POST['coffee']));
 $quantity = ($_POST['quantity']));
 $name = ($_POST['name']));
 $email = ($_POST['email']));
 $shipping_address = ($_POST['shipping_address']));
 $notes = ($_POST['notes'])); 
 }

$email_from ='paradigmcoffee@gmail.com';
$email_subject="New Order Submission";
$email_body ="You have received a new message from user $name.\n".
"Email_address:$email\n".
"Coffee: $coffee\n".
"Quantity: $quantity\n".
"Shipping_Address: $shipping_address\n".
"Notes: $notes\n".

$to ="paradigmcoffee@gmail.com";
$headers = "From: $email \r\n";

mail($to,$email_from,$email_subject,$email_body,$headers);
header("Location: http://www.paradigmcoffee.co/order_thanks.html");
?>

Answer 1

根据您提供的内容，您无法获取数据的原因可能是因为您没有发送任何名为 submit 的内容。尝试命名您的按钮：

<!-- name="submit" added -->
<button name="submit" type="submit" class="btn btn-black">Order Now</button>

您可以这样做或创建一个隐藏字段：

<input type="hidden" name="submit" value="1" />
