我试图弄清楚是否有一种相对简单的方法（我对 JQuery 不是很熟练）在表单提交后保持模式打开。（表单包含在模态中）。

如果表单成功或有错误，我的 PHP 会显示它们，但一旦按下提交按钮，模式就会关闭。

如果我重新加载表单，我可以看到相应的成功或错误消息，因此一切正常，但我希望最终用户看到消息，然后单击以关闭模式。

如果有帮助，我可以发布我的代码。

谢谢你。

<?php 
$success_message = "<h3 class='success'>Thank you, your message has been sent.</h3>"; 
$success = false; // we assume it and set to true if mail sent
$error = false;

// set and sanitize our form field values

$form = array(
  'Name' => $sanitizer->text($input->post->name),
  'Email' => $sanitizer->email($input->post->email),
  'Phone number' => $sanitizer->text($input->post->phone),
  'Type of client' => $sanitizer->text($input->post->client_type),
  'Service client is after' => $sanitizer->text($input->post->service),
  'Further information' => $sanitizer->textarea($input->post->information)
);

$required_fields = array(
  'name' => $input->post->name,
  'email' => $input->post->email
);


// check if the form was submitted
if($input->post->submit) {

  // determine if any fields were ommitted or didn't validate
  foreach($required_fields as $key => $value) {
    if( trim($value) == '' ) {
      $error_message = "<h3 class='error'>Please check that you have completed all the required fields.</h3>";
      $error = true;
    }
  }
  // if no errors, email the form results
  if(!$error) {
    $message = "";
    $to_name = "My name";
    $to = "me@me.com";
    $subject = "Contact Form request";
    $from_name = "My Website";
    $from = "do-not-reply@my-site.com";
    $headers = "From: $from_name <$from>";
    foreach($form as $key => $value) $message .= "$key: $value\n";

    require_once("./scripts/PHPMailer/class.phpmailer.php");

    $mail = new PHPMailer();
    $mail->CharSet = "UTF8";

    $mail->FromName = $from_name;
    $mail->From = $from;
    $mail->AddAddress($to, $to_name);
    $mail->Subject = $subject;
    $mail->Body = $message;

    if ($mail->Send()) {
      $success = true;
    }
}

为了不关闭模态窗口，即不刷新整个页面，您需要通过ajax调用将表单值提交给您的php脚本。

为简单起见，我将在这里使用 jQuery

$(function() {

    $('#your_form_id').on('submit', function(event) {

        event.preventDefault();

        $.ajax({
            url: "your_php_script.php",
            type: "POST",
            data: {"formFieldName" : formFieldValue}, // here build JSON object with your form data
            dataType: "json",
            contentType: "application/json"
        }).done(function(msg) {
            // this is returned value from your PHP script
            //your PHP script needs to send back JSON headers + JSON object, not new HTML document!
            // update your "message" element in the modal
            $("#message_element_id").text(msg);
        });
    });
};

当您提交表单时，页面会重新加载，即使action表单的页面是同一页面（空操作也意味着同一页面）。

我认为您想在页面再次加载后重新打开模式。猜测您正在使用method="post"表单，您的代码应该是这样的：

<html>
    <head>
      <!-- stuff -->
        <script type="text/javascript">

<?php if(isset($_POST['submit_button'])) { ?> /* Your (php) way of checking that the form has been submitted */

            $(function() {                       // On DOM ready
                $('#myModal').modal('show');     // Show the modal
            });

<?php } ?>                                    /* /form has been submitted */

        </script>
    </head>
    <body>
      <!-- etc -->
    </body>
 </html>

您还可以使用window.stop()这将阻止模型关闭和整个刷新一起，就像单击浏览器中的停止按钮一样。
