用ajax提交一組表單，裡麵包含一個圖片，
原來不用ajax提交的時候可以成功保存到資料庫，
但因為上傳前要壓縮圖片，所以改為ajax提交，ajax請求成功發送，但不能儲存到資料庫，
我想可能是控制器裡面的程式碼需要修改，但不知怎麼改，下面是程式碼。
ps:壓縮圖片用到了localResizeIMG插件。 https://github.com/think2011/localResizeIMG
下面是用ajax提交表單的視圖：

});

下面是原來沒用ajax時候的控制器，可以成功儲存到資料庫，現在不知怎麼改。
public function store(Requests\StoreArticleRequest $request)
{
$article = new Article($request->except('photo'));
$article -> user_id = \Auth::id();
$file = $request->file('photo');
$destinationPath = 'uploads/';
$extension = $file->getClientOriginalExtension();
$fileName = \Auth::user()->id . '_' . time() . '.' . $extension;
$file->move($destinationPath, $fileName);
$article -> photo = '/'.$destinationPath.$fileName;
$article->save();
return redirect()->action('ArticleController@show', ['id' => $article->id]);
}下面是StoreArticleRequest
## public function rules()
{
return [
'title'=>'required',
'content'=>'required',
'photo'=>'image'
];
}
