我正在尝试在我的网站上发送一个关于预订的电子邮件。但我无法解决我在PHP中的错误，非常初学PHP，所以不知道我哪里出错了。
在服务器上测试表单时，我没有收到任何电子邮件。
<?php
$firstname = $_post['firstname'];
$lastname = $_post['lastname'];
$bandname = $_post['bandname'];
$email = $_post['email'];
$phoneno = $_post['phoneno'];
$startday = $_post['start_day'];
$startmonth = $_post['start_month'];
$starthour = $_post['start_hour'];
$startminute = $_post['start_minute'];
$endday = $_post['end_day'];
$endmonth = $_post['end_month'];
$endhour = $_post['end_hour'];
$endminute = $_post['end_minute'];
$extras = $_post['extras'];
$to = "some@emailaddress.com";
$subject = "New Message";
mail ($to, $subject, $firstname . $lastname, $bandname, $email, $phoneno, $start_day . $start_month, $start_hour . $start_minute, $end_day . $end_month, $end_hour . $end_minute, $extras);
?>
我的表单的HTML：
<form action="form.php" class="appnitro" id="form_1062945" method="post" name="form_1062945" style="display: inline-block;">
<div class="form_description medium-8 small-10 columns medium-centered small-centered" style="margin-bottom:45px">
<p>
Please complete the form below to send us details of the booking you would like to make, we will then get back to you within one business day to confirm your booking.

答案 0 :(得分：3)
首先，您的所有$_post都不正确。
这是一个超级全球，必须读作$_POST。
然后你在mail()函数中注入了太多参数。
请阅读手册：
您的服务器可能未设置为捕获并显示/记录错误/通知/警告。
使用错误报告后，会向您发出许多通知。
将error reporting添加到文件的顶部，这有助于查找错误。
<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);
// rest of your code
旁注：只应在暂存时进行显示错误，而不是生产。
