我正在尝试在 YII 2.0 框架中使用 Activeform 复选框列表小部件
in my case, i have an array called "list" which has the names of languages which will be rendered out as checkboxlist, now i am able to do that, but i want the check boxes to be checked as the form loads.
就我而言，我有一个名为“list”的数组，其中包含将呈现为复选框列表的语言名称，现在我可以这样做，但我希望在表单加载时选中复选框。
$list = [0 => 'PHP', 1 => 'MySQL', 2 => 'Javascript'];
$list2 = [0,2];
using the following line, i am able to acheive what i want using HTML helper classes :
使用以下行，我可以使用 HTML 帮助类实现我想要的：
<?= Html::checkboxList('CuisineId',$list2,$list); ?>
but i want to be able to do this using the Activeform Widget CheckboxList, which as per documentationis to be used in the following way :
但我希望能够使用 Activeform Widget CheckboxList 来做到这一点，根据文档，它将以下列方式使用：
static checkboxList( $items, $options = [] )
静态 checkboxList( $items, $options = [] )
So in my case, i have figured how to pass the parameter for $items, which is in the following way:
所以就我而言，我已经想出了如何为 $items 传递参数，方法如下：
<?= $form->field($record, 'CuisineId')->checkboxlist($list);?>
But now i do not know how to pass the parameters that will allow the checkboxes to be checked.
但是现在我不知道如何传递允许检查复选框的参数。
