下拉搜索,我们先来看看预期的效果图
具体怎么实现喃?考虑到一张数据表要下拉效果的字段可能有很多个,我们先在其model中实现一个方法方便后续操作
/** * 下拉筛选 * @column string 字段 * @value mix 字段对应的值,不指定则返回字段数组 * @return mix 返回某个值或者数组 */ public static function dropDown ($column, $value = null) { $dropDownList = [ 'is_delete'=> [ '0'=>'显示', '1'=>'删除', ], 'is_hot'=> [ '0'=>'否', '1'=>'是', ], //有新的字段要实现下拉规则,可像上面这样进行添加 // ...... ]; //根据具体值显示对应的值 if ($value !== null) return array_key_exists($column, $dropDownList) ? $dropDownList[$column][$value] : false; //返回关联数组,用户下拉的filter实现 else return array_key_exists($column, $dropDownList) ? $dropDownList[$column] : false; }
然后我们上代码看看具体怎么实现的下拉搜索
= GridView::widget([ 'dataProvider' => $dataProvider, 'columns' => [ // ...... [ 'attribute' => 'is_hot', 'value' => function ($model) { return Article::dropDown('is_hot', $model->is_hot); }, 'filter' => Article::dropDown('is_hot'), ], [ 'attribute' => 'is_delete', 'value' => function ($model) { return Article::dropDown('is_delete', $model->is_delete); }, 'filter' => Article::dropDown('is_delete'), ], // ...... ], ]); ?>
像这样,我们就简单地实现了两个下拉效果,要实现筛选功能,在你的dataProvider自定添加该字段的搜索条件即可
