在wordpress表单提交中阻止页面刷新

标签: php jquery wordpress forms

我已经在我的wordpress网站上设置了一个小表单。但是当我按下提交按钮时页面重新加载并转到顶部,虽然表单已提交并显示成功消息。如何防止这种情况?我想要页面留在表单部分。我不希望用户向下滚动以查找表单中发生的事情。

PHP:               

  <?php 
  //If the form is submitted
  if(isset($_POST['submitted'])) {

    //Check to see if the honeypot captcha field was filled in
    if(trim($_POST['checking']) !== '') {
        $captchaError = true;
    } else {

        //Check to make sure that the name field is not empty
        if(trim($_POST['contactName']) === '') {
            $nameError = 'You forgot to enter your name.';
            $hasError = true;
        } else {
            $name = trim($_POST['contactName']);
        }

        //Check to make sure sure that a valid email address is submitted
        if(trim($_POST['email']) === '')  {
            $emailError = 'You forgot to enter your email address.';
            $hasError = true;
        } else if (!eregi("^[A-Z0-9._%-]+@[A-Z0-9._%-]+\.[A-Z]{2,4}$", trim($_POST['email']))) {
            $emailError = 'You entered an invalid email address.';
            $hasError = true;
        } else {
            $email = trim($_POST['email']);
        }

        //Check to make sure comments were entered  
        if(trim($_POST['comments']) === '') {
            $commentError = 'You forgot to enter your comments.';
            $hasError = true;
        } else {
            if(function_exists('stripslashes')) {
                $comments = stripslashes(trim($_POST['comments']));
            } else {
                $comments = trim($_POST['comments']);
            }
        }

        //If there is no error, send the email
        if(!isset($hasError)) {

            $emailTo = 'me@somedomain.com';
            $subject = 'Contact Form Submission from '.$name;
            $sendCopy = trim($_POST['sendCopy']);
            $body = "Name: $name \n\nEmail: $email \n\nComments: $comments";
            $headers = 'From: My Site <'.$emailTo.'>' . "\r\n" . 'Reply-To: ' . $email;

            mail($emailTo, $subject, $body, $headers);

            if($sendCopy == true) {
                $subject = 'You emailed Your Name';
                $headers = 'From: Your Name <noreply@somedomain.com>';
                mail($email, $subject, $body, $headers);
            }

            $emailSent = true;

        }
    }
  } ?>

提交时阻止HTML表单的默认行为:

 $('form#contactForm').submit(function(event) {
   event.preventDefault();
   // ...
 }
