gridview 如何实现区间查询 [ 2.0 版本 ]

可以用搜索功能实现啊，如图

用搜索啊，或者自己写都行的

不想写的话添加一个插件
composer require kartik-v/yii2-date-range

views

use kartik\daterange\DateRangePicker;
echo GridView::widget([
        'dataProvider' => $dataProvider,
        'filterModel' => $searchModel,
        'columns' => [
            ['class' => 'yii\grid\SerialColumn'],
            ....
            [
                'attribute' => 'created_at',
                'format' => ['date', 'php:Y-m-d H:i'],
                'filter' => DateRangePicker::widget([
                    'model' => $searchModel,
                    'attribute' => 'created_at',
                    'convertFormat' => true,
                    'pluginOptions' => [
                        'timePickerIncrement' => 30,
                        'locale' => [
                            'format' => 'Y-m-d',
                        ],
                        'opens' => 'left'
                    ]
                ]),
            ],
        ],
    ]);

search model

if (!empty($this->created_at)) {
    $created_at = explode(' - ', $this->created_at);
    $query->andFilterWhere(['between', 'created_at', strtotime($created_at[0]), strtotime('+1 day', strtotime($created_at[1])) - 1]);
}
