                如何使用 activeform 和模型在 yii2 中制作 dropdown?既然yii2中所有的方法都发生了变化,那么新的方法是怎么做的呢?

                How to make a dropdown in yii2 using an activeform and a model? Since all the methods has changed in yii2,how it is done in the new one?

                推荐答案

                就像

                <?php
                use yiihelpersArrayHelper;
                use backendmodelsStandard;
                ?>
                
                <?= Html::activeDropDownList($model, 's_id',
                      ArrayHelper::map(Standard::find()->all(), 's_id', 'name')) ?>
                

                Yii2 中的 ArrayHelper 替换了 Yii 1.1 中的 CHtml 列表数据.[请从您的控制器加载数组数据]

                ArrayHelper in Yii2 replaces the CHtml list data in Yii 1.1.[Please load array data from your controller]

                编辑

                从控制器加载数据.

                控制器

                $items = ArrayHelper::map(Standard::find()->all(), 's_id', 'name');
                ...
                return $this->render('your_view',['model'=>$model, 'items'=>$items]);
                

                在视图中

                <?= Html::activeDropDownList($model, 's_id',$items) ?>
