如何查看输入类型文件或隐藏在控制器的laravel中。

@if(isset($input_data['list_image_filename1'])) 
     <label for="list_image_filename1">{{ $input_data['list_image_filename1'] }}</label> 
     <input type="hidden" name="list_image_filename1" value="{{ $input_data['list_image_filename1'] }}"> 
    @else 
     <input class="form-control" name="list_image_filename1" type="file" id="list_image_filename1"> 
    @endif 

Answer 1

public function processForm(Request $request) 
{ 
    if ($request->file('list_image_filename1')) { 
     // it's file input 
    } elseif ($request->has('list_image_filename1')) { 
     // it's hidden input 
    } 
}
