PHP联系表不发送发件人电子邮件

Question

我不是一名程序员，但是我的开发工作已经完成，我需要修建客户旧网站，同时我们建立新的网站。

我的联系表单存在问题，当输入有效的电子邮件时，错误消息＆＃34;需要电子邮件＆＃34;显示，但表单仍然提交。

当我们收到电子邮件时，来自＆＃34;未知发件人＆＃34;和正文文本行＆＃34;电子邮件＆＃34;是空的。

PHP

    <?php

$errorMSG = "";

// NAME
if (empty($_POST["name"])) {
    $errorMSG = "Name is required ";
} else {
    $name = $_POST["name"];
}

// EMAIL
if (empty($_POST["email"])) {
    $errorMSG .= "Email is required ";
} else {
    $email = $_POST["email"];
}

// MESSAGE
if (empty($_POST["message"])) {
    $errorMSG .= "Message is required ";
} else {
    $message = $_POST["message"];
}


$EmailTo = "ned@heyflux.com";
$Subject = "New Message Received";

// prepare email body text
$Body = "";
$Body .= "Name: ";
$Body .= $name;
$Body .= "\n";
$Body .= "Email: ";
$Body .= $email;
$Body .= "\n";
$Body .= "Message: ";
$Body .= $message;
$Body .= "\n";

// send email
$success = mail($EmailTo, $Subject, $Body, "From:" .$email);

// redirect to success page
if ($success && $errorMSG == ""){
   echo "success";
}else{
    if($errorMSG == ""){
        echo "Something went wrong :(";
    } else {
        echo $errorMSG;
    }
}

?>
