從選擇字段存儲數組

Question

我想在我的數據庫中存儲縣的數組。這裏是我的刀片：

<select size="5" name="county[]" multiple class="form-control-2"> 
<option value="" selected="" disabled="">All Counties</option> 
@if (isset($counties)) 
    @foreach ($counties as $c) 
     <option value="{{ $c->name }}">{{ $c->name }}</option> 
    @endforeach 
@endif 

和我的控制器：

// Store the property Alert 
public function propertyAlert(PropertyAlertRequest $request) 
{ 
     $action = PropertySubscribe::create($request->all()); 
     $action = PropertySubscribe::create([ 
      $action->county = Input::get('county'), 
      ]); 
     $action->save(); 

    notify()->flash('Registered!', 'success', ['text' => 'You have now been registered.']); 
    return back(); 
} 

，我得到的錯誤是：

preg_replace(): Parameter mismatch, pattern is a string while replacement is an array 

誰能幫助我瞭解我是什麼做錯了？我將它作爲數組發送，並且dd正在顯示值。我是否需要對數組項目進行foreach？

Input::get('county')是返回一個數組，因爲你的select multiple

試試這個：

foreach(Input::get('county') as $county) 
{ 
    PropertySubscribe::create([ 
     $action->county = $county, 
    ]); 
}
