从ionic到php获取所选下拉列表值

我是爱奥尼亚的新手，对使用ajax不太熟悉，在下拉列表中获取所选值时遇到问题，我想使用ajax将其保存在数据库中

我在爱奥尼亚的观点有3个选项值
20分钟、30分钟和1小时

我想使用ng模型获得所选的值。这是包含我的服务的代码

    var returnRecipeData = {};

    return  {

        AddRecipe: function(thisrecipe){


            $http.post('http://localhost/admin-recipick/home/ajaxUserRecipe', thisrecipe).then(function(result){
                console.log(result);
            }, function(err){
                 console.error('ERR', err);
            });
        }

这是我的控制器

    $scope.newRecipe={};

    $scope.AddRecipe = function() {
    console.log("Adding Recipe");
    UserRecipeList.AddRecipe($scope.newRecipe);
    //console.log($scope.signupdata);
    //var registerThis = StudentList.register($scope.signupdata);*/

    if(UserRecipeList.AddRecipe){
      console.log("Recipe Added Successfully");
      $scope.login();
      $ionicPopup.alert({
                  title: 'Recipe Added Successfully!'
              });
    }
    else{
       $ionicPopup.alert({
                  title: 'Failed to Add! Please Try Again!'
              });
    }

。。最后，我想使用ajax将所选值发布到我的sql数据库中

        $data = array('Recipe_ID'       => null,
                      'Recipename'      => $post->name,
                      'Ingredients'     => $post->ingredients,
                      'Cookingtime'     => $post->ctime,---> this is the part where i want to post the value to my database. but getting an error.
                      'Procedure'       => $post->procedure,
                      'user_id'         => 1

            );
        $this->db->insert('UsersRecipes', $data);
        echo json_encode($this->db->insert_id());
    }

。。。但我有内部服务器错误。。请帮助..

尝试从第三方工具（如PostAndy）调用web服务，您是否看到我的代码中有错误？
