从选择字段存储数组

Question

我想在我的数据库中存储县的数组。这里是我的刀片：

<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(); 
} 

，我得到的错误是：

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

谁能帮助我了解我是什么做错了？我将它作为数组发送，并且dd正在显示值。我是否需要对数组项目进行foreach？

Input::get('county')是返回一个数组，因为你的select multiple

试试这个：

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