在更新帖子时检查Yii2中的checkboxList？

Question

我想在发布更新时检查Yii2 CheckboxList我的选项列表如下所述

<?= $form->field($category,'title')->checkboxList([1=>'Latest news','2'=>'Unit Performance','3'=>'Latest Technology'])->label(FALSE); ?>

我想检查在创建帖子时选择的更新时的某个项目like latest news.

请帮助我

Answer 1

使用示例代码行.

 $list = [1=>'Latest news','2'=>'Unit Performance','3'=>'Latest Technology'];

<?= $form->field($category,'title')->checkboxList($list)->label(FALSE); ?>

如果选择"最新消息"和"单位性能"选项,则更新时选择的选项值数组将为 $checkedList = [1, 2];

所以,只需将$checkedList数组分配给$category->title.像,

$category->title = $checkedList;

完整的例子是:

 $list = [1=>'Latest news','2'=>'Unit Performance','3'=>'Latest Technology'];

 if(!$category->isNewRecord) {
     $checkedList = [1, 2]; //get selected value from db if value exist
     $category->title = $checkedList;
 }

<?= $form->field($category,'title')->checkboxList($list)->label(FALSE); ?>
