这是feedbackform.php :(使用phpmailer）
<?php
if (isset($_POST['submit'])) {
$message = 'Full Name: ' . $_POST['fullname'] . '<br />
Subject: ' . $_POST['subject'] . '<br />
Phone: ' . $_POST['phone'] . '<br />
Email: ' . $_POST['emailid'] . '<br />
Comments: ' . $_POST['comments'] . '
';
require "PHPMailer/PHPMailerAutoload.php"; //include phpmailer class
// Instantiate Class
$mail = new PHPMailer();
// Set up SMTP
$mail->IsSMTP(); // Sets up a SMTP connection
$mail->SMTPAuth = true; // Connection with the SMTP does require authorization
$mail->SMTPSecure = "tsl"; // Connect using a TLS connection
$mail->Host = "smtp.gmail.com"; //Gmail SMTP server address
$mail->Port = 587; //Gmail SMTP port
//$mail->Encoding = '7bit';
// Authentication
$mail->Username = "abc@abc.com"; // Your full Gmail address
$mail->Password = "abc"; // Your Gmail password
// Compose
$mail->SetFrom($_POST['emailid'], $_POST['fullname']);
$mail->AddReplyTo($_POST['emailid'], $_POST['fullname']);
$mail->Subject = "New Contact Form Enquiry"; // Subject (which isn't required)
$mail->MsgHTML($message);
// Send To
$mail->AddAddress("abc@gmail.com", "abc"); // Where to send it - Recipient
$result = $mail->Send(); // Send!
$message = $result ? 'Successfully Sent!' : 'Sending Failed!';
unset($mail);
}
?>

听起来您的javascript正在拦截表单提交，验证，但如果验证成功则不会继续提交，因此问题出在验证中，而不是PHP或HTML部分。如果验证失败，那么当然它应该无法提交 - 这就是验证的重点。
虽然我在这里，但不要这样做：
$mail->SetFrom($_POST['emailid'], $_POST['fullname']);
这将导致您的邮件无法通过SPF检查。将该信息放在邮件正文和回复中（正如您所做），但将发件人地址设置为您自己的地址，而不是提交者，如下所示：
$mail->SetFrom("abc@gmail.com", "abc");
$mail->AddReplyTo($_POST['emailid'], $_POST['fullname']);
$mail->AddAddress("abc@gmail.com", "abc");
这意味着来自地址不是伪造的，也不会使SPF检查失败，但您将能够直接回复提交者。
