发送电子邮件而不发送其他字段PHP - Send email not sending other fields PHP

所以这是我的php代码：

发送电子邮件.php

<?php 
$ToEmail = 'email@mail.com';
$EmailSubject = 'Request Lawn Mowing Quote';
$mailheader = "From: ".$_POST["email"]."'r'n";
$mailheader. = "Reply-To: ".$_POST["email"]."'r'n";
$mailheader. = "Content-type: text/html; charset=iso-8859-1'r'n";
$MESSAGE_BODY = "Name: ".$_POST["name"]."";
$MESSAGE_BODY. = "<br>Country/State: ".$_POST["states"]."";
$MESSAGE_BODY. = "<br>Suburb: ".$_POST["suburb"]."";
$MESSAGE_BODY. = "<br>Unit/Street No.: ".$_POST["unit"]."";
$MESSAGE_BODY. = "<br>Street Name: ".$_POST["street"]."";
$MESSAGE_BODY. = "<br>Phone: ".$_POST["phone"]."";
$MESSAGE_BODY. = "<br> Email: ".$_POST["email"]."";
$MESSAGE_BODY. = "<br> Service: ".$_POST["service"]."";
$MESSAGE_BODY. = "<br> Comment: ".nl2br($_POST["comment"])."";
mail($ToEmail, $EmailSubject, $MESSAGE_BODY, $mailheader) or die("Failure");
?>

这是有效的，但并非所有字段都发送给收件人。如复选框字段（服务）、名称、国家/州、郊区、街道名称和注释。请帮我找出代码中缺少或错误的地方。谢谢

请注意，复选框可以是一个数组。您应该在复选框字段中使用name="service[]"，而不是name="service"。然后，在将输入插入电子邮件时，使用implode(', ', $_POST['service']);，因为它将是一个数组。

当您print_r($_POST);时会发生什么？

首先检查

echo "<pre>";
print_r($_POST);
echo "<pre>";

然后检查您必须定义

$MESSAGE_BODY = "";

如果您没有通过错误Undefined variable $MESSAGE_BODY 定义它

最后一次检查

echo "<pre>";
print_r($MESSAGE_BODY);
echo "<pre>";

编辑将其添加到mail(); 的上方

$mailheader  = "MIME-Version: 1.0" . "'r'n";
$mailheader .= "Content-type:text/html;charset=iso-8859-1" . "'r'n";
