PHP Angular JS联系人表单将't张贴

当我试图发布到我的php表单时，我一直收到"请完整填写表单！"错误。

当我尝试提交联系表格时出现的错误这是我的角度

  var app = angular.module('app', ['ngRoute']);
    app.config(['$routeProvider',
      function($routeProvider) {
        $routeProvider
          .when('/home', {
            templateUrl: 'pages/partial.home.html',
            controller: 'homecontroller'
          })
          .when('/about', {
            templateUrl: 'pages/partial.about.html',
            controller: 'aboutcontroller'
          })
          .when('/services', {
            templateUrl: 'pages/partial.services.html',
            controller: 'servicecontroller'
          })
          .when('/contact', {
            templateUrl: 'pages/partial.contact.html',
            controller: 'contactcontroller'
          })
          .when('/portfolio', {
            templateUrl: 'pages/partial.portfolio.html',
            controller: 'portfoliocontroller'
          });
        /* .otherwise({
        templateUrl:'pages/partial.404.html'
       });*/
      }
    ]);
    app.controller('homecontroller', ['$scope', '$http',
      function($scope, $http) {
        $scope.title = 'About Us';
      }
    ]);
    app.controller('aboutcontroller', ['$scope', '$http',
      function($scope, $http) {
        $scope.title = 'About Us';
      }
    ]);
    app.controller('servicecontroller', ['$scope', '$http',
      function($scope, $http) {

      }
    ]);
    app.controller('contactcontroller', ['$scope', '$http',
      function($scope, $http) {

        $scope.submitButtonDisabled = false;
        $scope.submitted = false;
        $scope.submit = function(contactform) {
          $scope.submitted = true;
          $scope.submitButtonDisabled = true;
          if (contactform.$valid) {
            $http({
              method: 'POST',
              url: 'bin/contact_form.php',
              data: $.param($scope.formData), //param method from jQuery
              headers: {
                'Content-Type': 'application/x-www-form-urlenconded'
              }
            }).success(function(data) {
              console.log(data);
              if (data.success) { //success comes from the return json object
                $scope.submitButtonDisabled = true;
                $scope.resultMessage = data.message;
                $scope.result = 'bg-success';
              } else {
                $scope.submitButtonDisabled = false;
                $scope.resultMessage = data.message;
                $scope.result = 'bg-danger';
              }
            });
          } else {
            $scope.submitButtonDisabled = false;
            $scope.resultMessage = 'Oops, Failed to send!';
            $scope.result = 'bg-danger';
          }

    app.controller('portfoliocontroller', ['$scope', '$http',
      function($scope, $http) {

这里是我的php代码

    <?php
error_reporting(E_ALL);

        $data = array('success' => false, 'message' => 'Please fill out the form completely.');
        echo json_encode($data);
        exit;
    }
    $usermail = $_POST['inputEmail']; //get sender mail address
    $sender = $_POST['inputName']; // get sender Name
    $from  = "*@gmail.com"; //SMTP mail address
    $mail = new PHPMailer();
