Angular Controller不顯示消息

Question

我是Angular / Bootstrap開發的新手，我的網站上有一個聯系表，該表使用Angular控制器對PHP文件進行AJAX調用，然后發送電子郵件。

雖然一切正常〜AJAX通話並發送電子郵件，但它應該在屏幕上顯示帶有一些文本的警報欄。 由於某種原因，它僅顯示“ bg-danger”欄（成功時應顯示bg-success欄），而從不顯示文字消息。

這是聯系表單成功發送消息后發生的情況的圖像

我的聯系表單HTML：

<div class="container" ng-controller="ContactController">
  <div class="row">
    <div class="col-md-12">
              <div class="well well-sm">
                  <form class="form-horizontal" method="post" role="form" ng-submit="submit(contactform)" name="contactform">
                      <fieldset>
                          <legend class="text-center header">Send us a Message</legend>

                      </fieldset>
                      <p ng-class="result" style="padding: 15px; margin: 0;">{{ resultMessage }}</p>
                  </form>
              </div>
          </div>
      </div>
  </div>

我的角度控制器：

var app = angular.module("myApp", ["ngRoute", "ngAnimate", "ngCsv"]);
app.config(function ($routeProvider) {
    $routeProvider.when("/", {
        templateUrl: "templates/home.html"
    }).when("/contact", {
        controller: 'ContactController',
        templateUrl: "templates/contact.html"
  })
});

app.controller('ContactController', function ($scope, $http) {
    $scope.result = 'hidden'
    $scope.resultMessage;
    $scope.formData; //formData is an object holding the name, email, subject, and message
    $scope.submitButtonDisabled = false;
    $scope.submitted = false; //used so that form errors are shown only after the form has been submitted
    $scope.submit = function(contactform) {
        $scope.submitted = true;
        $scope.submitButtonDisabled = true;
        if (contactform.$valid) {
            $http({
                method  : 'POST',
                url     : 'php/contact.php',
                data    : $.param($scope.formData),  //param method from jQuery
                headers : { 'Content-Type': 'application/x-www-form-urlencoded' }  //set the headers so angular passing info as form data (not request payload)
            }).success(function(data){
                console.log(data);
                if (data.success) { //success comes from the return json object
                    $scope.submitButtonDisabled = false;
                    $scope.result='bg-success';
                    $scope.resultMessage = data.message;
                    //$scope.result='alert alert-success';
                } else {
                    $scope.submitButtonDisabled = true;
                    $scope.resultMessage = data.message;
                    $scope.result='bg-danger';
                }
            });
        } else {
            $scope.submitButtonDisabled = false;
            $scope.resultMessage = 'Failed <img src="http://www.chaosm.net/blog/wp-includes/images/smilies/icon_sad.gif" alt=":(" class="wp-smiley">  Please fill out all the fields.';
            $scope.result='bg-danger';
        }
    }
});

我在服務器端的PHP代碼，用於發送電子郵件。

<?php
require_once ("class.phpmailer.php");   // Include phpmailer class
  ini_set('display_errors', 'On');
  error_reporting(E_ALL | E_STRICT);

  if (isset($_POST['inputFirstName']) && isset($_POST['inputLastName']) && isset($_POST['inputEmail']) && isset($_POST['inputPhone']) && isset($_POST['inputMessage'])) {

    //check if any of the inputs are empty
    if (empty($_POST['inputFirstName']) || empty($_POST['inputLastName']) || empty($_POST['inputEmail']) || empty($_POST['inputPhone']) || empty($_POST['inputMessage'])) {
        $data = array('success' => false, 'message' => 'Please fill out the form completely.');
        echo json_encode($data);
        exit;
    }

    $message=
    'First Name:    '.$_POST['inputFirstName'].'<br />
    Last Name:  '.$_POST['inputLastName'].'<br />
    Phone:  '.$_POST['inputPhone'].'<br />
    Email:  '.$_POST['inputEmail'].'<br />
    Comments:   '.$_POST['inputMessage'].'
    ';

    $mail = new PHPMailer();        // Instantiate the PHPMailer Class
    $mail->IsSMTP();                // enable SMTP
    $mail->SMTPDebug = 1;           // debugging: 1 = errors and messages, 2 = messages only
    $mail->SMTPAuth = true;         // SMTP authentication enabled
    $mail->SMTPSecure = 'ssl';      // secure transfer enabled + REQUIRED for Gmail (either SSL or TLS)
    $mail->Host = "smtp.gmail.com"; //Gmail SMTP Server to relay thru
    $mail->Port = 465; // Port 465 as we're using SSL... or use Port 587 for TLS
    $mail->IsHTML(true);                               // We're sending a HTML formatted message
    $mail->Username = "*****@gmail.com"; // Gmail account for authentication
    $mail->Password = "*********";                     // Gmail password for authentication
    $mail->SetFrom("*****@gmail.com");   // The email is being sent from this address
    $mail->Subject = "Website Contact Form Enquiry";   // The subject line of the email
    $mail->Body = ($message);                          // The actual email message to be sent
    $mail->AddAddress("*****@gmail.com"); // The email is being sent to this address

  //if (isset($_POST['ref'])) {
  //     $mail->Body .= "\r\n\r\nRef: " . $_POST['ref'];
  // }

   if(!$mail->send()) {
     $data = array('success' => false, 'message' => 'Message could not be sent. Mailer Error: ' . $mail->ErrorInfo);
     echo json_encode($data);
     exit;
   }

   $data = array('success' => true, 'message' => 'Thanks! We have received your message.');
   error_log("Data: ".$data['success']." Message: ".$data['message']);
   echo json_encode($data);
   //error_log("Data: ".$data['success']);

 } else {

     $data = array('success' => false, 'message' => 'Please fill out the form completely.');
     echo json_encode($data);

 }
?>

**更新-問題出在Angular方面，我將控制器更改為此代碼，但現在它始終成功。 另外，不管我嘗試什么，盡管控制台日志顯示是從PHP獲取消息，但它從不顯示消息：

if (contactform.$valid) {
            var request = $http({
                method  : 'POST',
                url     : 'php/contact.php',
                data    : $.param($scope.formData),  //param method from jQuery
                headers : { 'Content-Type': 'application/x-www-form-urlencoded' }  //set the headers so angular passing info as form data (not request payload)
            });
            if (request.success) { //success comes from the return json object
                console.log(request);
                $scope.submitButtonDisabled = false;
                $scope.result='bg-success';
                $scope.resultMessage = "'Thanks!... We have received your message, and will be in contact shortly"
              } else {
                $scope.submitButtonDisabled = true;
                $scope.resultMessage = "Opps!... something went wrong.  Please Contact OpenHouse directly to let them know of this error.";
                $scope.result='bg-danger';
            };
            //);

改變它看起來像這個胸罩

        $http({
            method  : 'POST',
            url     : 'php/contact.php',
            data    : $.param($scope.formData),  //param method from jQuery
            headers : { 'Content-Type': 'application/x-www-form-urlencoded' }  //set the headers so angular passing info as form data (not request payload)
        }).success(function (response) {
          console.log(response); // object (not boolean)
        }).error(function (response) {

        });
