Php 表单到电子邮件，表单未发布到我的邮件

让我们尝试使用此函数发送它：

$to      = $_POST['to'];
$subject = $_POST['subj'];
$message = $_POST['message'];
$from    = 'robot@' . $_SERVER['HTTP_HOST'];

back.php

以下是一些输入数据：

<?php 
// code goes here
$to = ""; // this is your Email address
$from = $_POST['email']; // this is the sender's Email address
$name = $_POST['name'];
$one = $_POST['one'];
$two = $_POST['two'];
$three = $_POST['three'];
$four = $_POST['four'];
$subject = "Form submission";
$subject2 = "Copy of your form submission";
$message = $name . " " . $one . " " . $two . " " . $three . " " . $four . " " . "\n\n" . $_POST['message'];
$message2 = "Here is a copy of your message " . $name . "\n\n" . $_POST['message'];

$headers = "From:" . $from;
$headers2 = "From:" . $to;
mail($to,$subject,$message,$headers);
mail($from,$subject2,$message2,$headers2); // sends a copy of the message to the sender
echo "Thankyou for your feedback " . $name;

?>

以下是函数：

$to      = $_POST['to'];
$subject = $_POST['subj'];
$message = $_POST['message'];
$from    = 'robot@' . $_SERVER['HTTP_HOST'];

以下是如何使用它：

function send_mail($to, $from, $subject, $message) {
  $headers = ['From: ' . $from, 'Reply-To: ' . $from, 'X-Mailer: PHP/' . phpversion()]
  return mail($to, $subject, $message, implode("\r\n", $headers));
}

index.html 表格如下：

send_mail($to, $from, $subject, $message);

您能显示代码吗？html代码@DieterMemkenis

$to

确实是空的，或者您出于隐私原因刚刚删除了该地址？您是否收到任何错误消息？我们能提供什么帮助？我删除它是为了隐私@twinfriends如果它没有帮助，请提供每个变量的var_dump。第二：检查你的目标电子邮件。第三：在你的收件箱中检查“垃圾邮件”。你能给我一个提交表单数据的代码吗？因为av做了很多，但仍然没有结果，你可以使用上面的php来指导你使用变量@Мааааааааач
