pagination - yii2：具有分页和 searcModel 的 SqlDataProvider 出现错误 preg_match() 期望参数 2 是字符串，给定对象

Question

我想使用 sqlDataProvider 从不同的表中显示数据到 gridview 并计算它，这是我在 siteController.php 中的代码
public function actionSyahriyah() { $searchModel = new SyahriyahSearch(); $db = Yii::$app->db; $bayar = $db ->createCommand('SELECT sy.no_syahriyah, sy.banyak, sa.nama, sy.tgl, sa.tarif FROM santri sa, syahriyah sy WHERE sa.no_induk = sy.no_induk ORDER BY sy.tgl'); $dataProvider = new SqlDataProvider([ 'sql' => $bayar, 'pagination' => [ 'pageSize' => 5 ], ]); return $this->render('syahriyah',[ 'searchModel' => $searchModel, 'dataProvider' => $dataProvider, ]); }
，这是 gridview：
<?= GridView::widget([ 'dataProvider' => $dataProvider, 'filterModel' => $searchModel, 'columns' => [ // ['class' => 'yii\grid\SerialColumn'], 'tgl', 'banyak', ], 'export' => false, ]); ?>

Answer 1

您可以使用数据提供者

<?php

    $bayar = $db ->createCommand('SELECT sy.no_syahriyah, sy.banyak, sa.nama, sy.tgl, sa.tarif 
           FROM santri sa, syahriyah sy 
           WHERE sa.no_induk = sy.no_induk
           ORDER BY sy.tgl');

    $dataProvider = new SqlDataProvider([
        'sql' => $bayar,
        'pagination' => [
            'pageSize' => 5 
            ],
        ],
    ]);

?>
