你可以這樣寫。這將解決您的問題

public function update($id) 
{ 
    $users = AdminLogin::find($id); 

    if(Input::hasFile('image_file')) 
    { 
     $usersImage = public_path("uploads/images/{$users->image_file}"); // get previous image from folder 
     if (File::exists($usersImage)) { // unlink or remove previous image from folder 
      unlink($usersImage); 
     } 
     $file = Input::file('image_file'); 
     $name = time() . '-' . $file->getClientOriginalName(); 
     $file = $file->move(('uploads/images'), $name); 
     $users->image_file= $name; 
    } 
    $users->save(); 
    return response()->json($users); 
} 

這將刪除以前的圖像和更新的新形象
