Neden güncelleme sorgusu sadece durumunda meydana gelen bu hata? Lütfen bu sorunu düzeltmek için kararlı ve doğru bir yöntemle bana yardımcı olun ... Şimdiden teşekkürler. senin AdminController.php yılında

Answer 1

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

, bkz:

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'], 
     ]); 
    ...   
} 

Bunun yerine, bu olmalıdır:

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'], 
     ]; 
    ...   
}
