复选框组总是返回空值。

Question

我有一个奇怪的问题，拉拉和复选框。

我有一组复选框，无法在数据库中保存值。

我的迁徙：

$table->json('send_reminder')->nullable();

我的模特：

protected $fillable = [
  .....
    'send_reminder',
  ....
];

我的index.php

类索引扩展组件{ public .$send_reminder，....

我的表格index.blade.php

<div class="input-group input-group-static my-3">
      <div class="form-control @error('reminder') is-invalid @enderror">
            Notification interval: <br>                                             
         @foreach(\App\Enums\ReminderInterval::options() as $option => $reminder)
          <label>
             <input name="send_reminder[]" value="{{(str_replace('_','',$option))}}"
                    type="checkbox">
                    {{(str_replace('_',' ',$option))}}
          </label><br>
        @endforeach
</div>

当我试图将数据保存到变量和DD数据时，字段总是为null。

$data = [
      ....other data...
      'send_reminder' => $this->send_reminder
      ];
      dd($data);

你能帮帮我吗?谢谢!

不确定您的代码的其余部分，如果您发布了所有的代码，您将能够得到更多的帮助。话虽如此，livewire并不只是查找页面上的输入，您需要通过使用wire:model="send_reminder"让它知道

工作示例：示例

test-field.blade.php

<div>
    <input wire:model="send_reminder" name="send_reminder[]" value="1" type="checkbox">
    <input wire:model="send_reminder" name="send_reminder[]" value="2" type="checkbox">
    <input wire:model="send_reminder" name="send_reminder[]" value="3" type="checkbox">
    <input wire:model="send_reminder" name="send_reminder[]" value="4" type="checkbox">

    <div>{{ print_r($send_reminder) }}</div>
</div>

TestField.php

class TestField extends Component
{
    public $send_reminder = array();

    public function render()
    {
        return view('livewire.test-field');
    }
}
