从选择字段存储数组 - Store array from select field

Store array from select field

本文关键字：数组存储字段选择 | 更新日期: 2023-09-27

我试图在我的数据库中存储县数组。这是我的刀片:

<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

，我的控制器是:

// 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

谁能帮我理解我做错了什么?我把它作为一个数组发送，dd成功地显示了值。我需要对数组项进行查询吗?

Input::get('county')返回一个数组，因为您的select multiple

试试这个:

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