的MediaController

public function update(Request $request, $id) 
{ 
    $media = Media::findOrFail($id); 
    if($request->hasFile('UserFile')) { 
     $image = $request->file('UserFile'); 
     $filename = $image->getClientOriginalName(); 
     Image::make($image)->resize(300, 300)->save(public_path('media/' . $filename)); 
     $media->MediaPath = $filename; 
     $media->MediaName = $filename; 
     $media->Description = $request->Description ? $request->Description : ''; 
     $media->save(); 
    } 

    return response()->json($media); 

}

return false; 
}); 

我把MEDIANAME，描述和userfile的

當我點擊提交，我得到的數據是這樣

我無法更新數據，當我嘗試更新他們，我的數據沒有改變。 我不知道爲什麼，我覺得我沒有做錯事在我的代碼。請幫我解決這個問題，如果你知道答案

Answer 1

更改路線的PUT POST到路線

Route::resource('/mediafile', 'MediaController', ['except' => ['update']]); 
Route::post('/mediafile/{id}', 'MediaController@update'); 

由於表單數據只能在方法POST中使用，因此如果要更新圖片，則必須使用POST方法。

Answer 2

<form name="itemGroupForm" action="{{URL::to('editItem',$items[0]->id)}}" id="itemGroup" data-parsley-validate="" method="post" onsubmit="return submitFormItemGroup();"> 

    function submitFormItemGroup() { 
    var form_data = new FormData(document.getElementById("itemGroup")); 
    form_data.append("label", "WEBUPLOAD"); 
    $.ajax({ 
     url: "{{URL::to('editItem',$items[0]->id)}}}", 
     type: "POST", 
     data: form_data, 
     processData: false, // tell jQuery not to process the data 
     contentType: false // tell jQuery not to set contentType 
    }).
