laravel 5.2：ErrorException：にpreg_replace（）：交換が、私はlaravelに新しいですし、私は私の研究の目的のためにlaravel 5.2でプロジェクトをやっている配列

Question

ありながら、パラメータの不一致、パターンが文字列です。しかし、私はフォームのデータを更新するときにいくつかのエラーで立ち往生した。挿入、選択、削除のクエリはエラーなく正常に動作しています。以下に示すように、エラーが表示されている更新クエリを使用しながら、しかし：にpreg_replace（）：helpers.phpライン683に

あるが、パターンは、文字列であります更新用フォーム（editmenutype.blade.php）のビューファイルのために私が書いたコードされています。与えられた以下

<form class="form-horizontal" method="post" action="{{action('AdminController@updatemenutype')}}"> 
      <input type="hidden" name="_token" value="{{csrf_token()}}" /> 
      <input type="hidden" name="eid" value="{{$row->id}}" />       
       <div class="box-body"> 
       <label>Menu-Type Name:</label> 
       <div class="input-group"> 
        <div class="input-group-addon"> 
        <i class="fa fa-fire"></i> 
        </div> 
      <input type="text" name="menutype" class="form-control" value="{{$row->menutype}}" placeholder="Enter Menu-Type Name..." required="required" maxlength="100"> 
       </div><!-- /.input group --> 
       </div><!-- /.form group -->  
       <div class="box-body"> 
       <label>Publishing Status:</label> 
       <div class="input-group"> 
        <div class="input-group-addon"> 
        <i class="fa fa-globe"></i> 
        </div> 
        <select name="status" class="form-control" style="width: 100%;" required="required"> 
         <option value="{{$row->status}}" disabled="disabled"><?php if($row->status==1){echo "Yes"; }else{echo "No";} ?></option>       
         <option value="1">Yes</option> 
         <option value="0">No</option> 
        </select> 
       </div><!-- /.input group --> 
       </div><!-- /.form group -->      
       <div class="box-footer"> 
        <input type="reset" name="reset" class="btn btn-default" value="Cancel"> 
        <input type="submit" name="submit" class="btn btn-info pull-right" value="Edit Menu-Type"> 
       </div> 
       </form> 

は、データを更新するためのコントローラで書かれた私の対応機能（AdminController.php）です。

与えられた以下

public function editmenutype($id) { 
    $row = DB::table('menutypes')->where('id',$id)->first(); 
    return view('admin.editmenutype')->with('row',$row); 
} 

public function updatemenutype(Request $request) { 
    $post=$request->all(); 
    print_r($post); 
    //var_dump($post); 
    $v=\Validator::make($request->all(), 
    [ 
     'menutype' => 'required', 
     'status' => 'required', 
    ]); 
    if($v->fails()) 
    { 
     return redirect()->back()->withErrors($v->errors()); 
    } 
    else 
    { 
     $data = array(
     [ 
      'menutype' => $post['menutype'], 
      'status' => $post['status'], 
     ]); 
     $i = DB::table('menutypes')->where('id',$post['eid'])->update($data); 
     if($i > 0) 
     { 
      \Session::flash('message','* Menu-Type Updated Successfully.'); 
      return redirect('/admin/managemenutypes'); 
     } 
    } 
} 

は、私は、ルートファイル（routes.phpの）対応するページを呼び出すために与えられ、対応するコードです：

Route::get('admin/editmenutype/{id}','AdminController@editmenutype'); 
Route::post('admin/updatemenutype','AdminController@updatemenutype'); 

なぜ更新クエリのみの場合に発生し、このエラー？この問題を解決するための安定した正しい方法で私を助けてください...事前に感謝します。あなたのAdminController.phpで

Answer 1

array() and \[\] are both declarations of an empty array.

、以下を参照してください

public function updatemenutype(Request $request) { 
    ... 
    if($v->fails()) 
    { 
     return redirect()->back()->withErrors($v->errors()); 
    } 
    else 
    { 
     //Error is here: array within array 
     $data = array(
     [ 
      'menutype' => $post['menutype'], 
      'status' => $post['status'], 
     ]); 
    ...   
} 

を代わりに、それは次のようになります。

public function updatemenutype(Request $request) { 
    ... 
    if($v->fails()) 
    { 
     return redirect()->back()->withErrors($v->errors()); 
    } 
    else 
    { 
     //Single array declaration 
     $data = 
     [ 
      'menutype' => $post['menutype'], 
      'status' => $post['status'], 
     ]; 
    ...   
}
