PHP 电子邮件问题与$Error消息

在Linux服务器上，我有一个ajax表单，它被发布到js脚本中，而js脚本又发布到php例程中，用于发送网站电子邮件联系表单（Styleshout-Puremedia模板）。我知道这篇文章发生在js和php页面上。我在 php 页面上收到一个 httpd 服务器错误，指出"$Error未定义"。但是，如果我将其定义为 NULL 或"，它存在，因此无法通过"if （！$Error）"测试。如果我使用 mail 函数创建一个硬编码的 php 脚本，电子邮件就可以正常工作，因此 php 和 sendmail 都配置正确。有人可以帮助为什么这个php脚本不起作用，或者如何修复"$Error"错误吗？

PHP代码：

<?php
// Replace this with your own email address
$siteOwnersEmail = 'info@mydomain.com';
if($_POST) {
	
   $fname = trim(stripslashes($_POST['contactFname']));
   $lname = trim(stripslashes($_POST['contactLname']));
   $email = trim(stripslashes($_POST['contactEmail']));
   $subject = trim(stripslashes($_POST['contactSubject']));
   $contact_message = trim(stripslashes($_POST['contactMessage']));
   // Check First Name
	if (strlen($fname) < 2) {
		$error['fname'] = "Please enter your first name.";
	}
	// Check Last Name
	if (strlen($lname) < 2) {
		$error['lname'] = "Please enter your last name.";
	}
	// Check Email
	if (!preg_match('/^[a-z0-9&'''.'-_'+]+@[a-z0-9'-]+'.([a-z0-9'-]+'.)*+[a-z]{2}/is', $email)) {
		$error['email'] = "Please enter a valid email address.";
	}
	// Check Message
	if (strlen($contact_message) < 15) {
		$error['message'] = "Please enter your message. It should have at least 15 characters.";
	}
   // Subject
	if ($subject == '') { $subject = "Contact Form Submission"; }
	// Set Name
	$name = $fname . " " . $lname;
   // Set Message
   $message = "Email from: " . $name . "<br />";
   $message .= "Email address: " . $email . "<br />";
   $message .= "Message: <br />";
   $message .= $contact_message;
   $message .= "<br /> ----- <br /> This email was sent from your site's contact form. <br />";
   // Set From: header
   $from =  $name . " <" . $email . ">";
   // Email Headers
	$headers = "From: " . $from . "'r'n";
	$headers .= "Reply-To: ". $email . "'r'n";
 	$headers .= "MIME-Version: 1.0'r'n";
	$headers .= "Content-Type: text/html; charset=ISO-8859-1'r'n";
   if (!$error) {
      ini_set("sendmail_from", $siteOwnersEmail); // for windows server
      $mail = mail($siteOwnersEmail, $subject, $message, $headers);
		if ($mail) { echo "OK"; }
      else { echo "Something went wrong. Please try again."; }
		
	} # end if - no validation error
	else {
		$response = (isset($error['fname'])) ? $error['fname'] . "<br /> 'n" : null;
		$response .= (isset($error['lname'])) ? $error['lname'] . "<br /> 'n" : null;
		$response .= (isset($error['email'])) ? $error['email'] . "<br /> 'n" : null;
		$response .= (isset($error['message'])) ? $error['message'] . "<br />" : null;
		
		echo $response;
	} # end if - there was a validation error
}
?>
