Php 登陆/刷新网站时发送电子邮件的表格

每次我访问或刷新我的网站时，我的表单都会向我发送一封空白电子邮件（字段数据为空）

我看了几篇提到“Post/Redirect/Get”的帖子，但这让我感到困惑而不是帮助，我不确定这是否与我的问题有关

这是我在网上找到的一个基本的响应表单，我必须找到PHP来实际发送表单数据。（根据我的需要进行更改）

我希望我在某个地方漏掉了一个错误，但我似乎找不到

任何帮助都将不胜感激。提前谢谢

以下是基本形式（减去css）：

PHP:

HTML:

打声招呼！
填好下面的表格，我会尽快给你回复。谢谢
姓名：（必填）
电子邮件：（必选）
电话：（必选）
信息：（必选）
发送电子邮件

使用

isset

<?php
if(isset($_POST['submit']))
{
$name = $_POST['name'];
$email = $_POST['email'];
$phone = $_POST['phone'];
$message = $_POST['message'];
$formcontent=" From: $name \n Phone: $phone \n Email: $email \n Message: $message";
$recipient = "MY EMAIL HERE";
$subject = "Portfolio Contact Form";
$mailheader = "From: $email \r\n";
mail($recipient, $subject, $formcontent, $mailheader) or die("Error!");
echo "Thank You!";
}
?>

只有当你的邮件由任何人提交时，它才会发布你的邮件。

我已经在stackoverflow链接中为其他人发布了这封邮件 这是我的代码。让我们试试，我希望它能帮助你

<?PHP
$email = $_POST["emailaddress"];
$to = "you@youremail.com";
$subject = "New Email Address for Mailing List";
$headers = "From: $email\n";
$message = "A visitor to your site has sent the following email address to be added to your mailing list.\n

Email Address: $email";
$user = "$email";
$usersubject = "Thank You";
$userheaders = "From: you@youremailaddress.com\n";
$usermessage = "Thank you for subscribing to our mailing list.";
mail($to,$subject,$message,$headers);
mail($user,$usersubject,$usermessage,$userheaders);
?>

非常感谢：您在“if”（isset（$\u POST['submit']）的末尾缺少了一个额外的“）”，但效果不错。感谢您的帮助。干杯。
