PHP表单到电子邮件 - 输入不发送到电子邮件

Question

this->setWindowOpacity(0.5);

我正在尝试添加的代码（

<?php

// Function that validates your formfields and generate errors
function validate($name, $email)
{
$errors = array();

// validation for name
if(strlen($name) < 2)
    $errors[] = 'You did not enter a name.';

// validation for email
if(!strlen($email))
    $errors[] = 'non-valid email.';
else if(!filter_var($email, FILTER_VALIDATE_EMAIL))
    $errors[] = 'valid email.';

// return array with errors
return $errors;
}

// initialization of variables with default values
$name = '';
$email = '';
$errors = array();

// if the form has been submited
if($_SERVER['REQUEST_METHOD'] == 'POST')
{
// overwrite the variables with the $_POST elements
$name = $_POST['name'];
$email = $_POST['email'];

）

$recipient = 'example@gmail.com';
$subject = 'Simple Forms';
$mailheader = 'From: $email \r\n';
$formcontent = '$name, $email';

我正在尝试添加的代码（

// validate the variables
$errors = validate($name, $email);

// If there aren't any errors redirect to another page
if(!count($errors))
{
    // Here comes the place to send an email!!!

）

   mail($recipient, $subject, $formcontent, $mailheader) or die("Error!");

电子邮件正确地发送给收件人并使用正确的主题行，但它来自$ email rn，电子邮件的正文为：$ name，$ email。

示例电子邮件）

来自：$ email rn to：example@gmail.com 简单表格

$ name，$ email

它非常接近工作，但我不确定如何正确使用$ name和$ email变量。任何建议将不胜感激。
