yii2:Custom Pagination for Gridview in form view
提问by Pawan
I have included the Gridview widget in _form.phpfile, which is working well. The problem is the filter and pagination.
我在_form.php文件中包含了 Gridview 小部件，它运行良好。问题是过滤器和分页。
<?php
$dataProvider = new ActiveDataProvider([
'query' => \app\models\ServiceCharges::find(),
'pagination' => [
'pageSize' => 5,
],
]);
?>
<?php
$searchModel = New \app\models\ServiceChargesSearch();
$dataProvider = $searchModel->search(Yii::$app->request->queryParams);
?>
</div>
</div>
<div>
<?= GridView::widget([
'dataProvider' => $dataProvider,
'filterModel' => $searchModel,
'columns' => [
['class' => 'yii\grid\SerialColumn'],
'id',
'service_name',
'room_category',
'charges_cash',
'charges_cashless',
['class' => 'yii\grid\ActionColumn'],
],
]); ?>
</div>
If I am putting the $dataproviderpagination part below the $searchmodel, pagination works fine, but then filter doesn't work and vice-versa.
如果我将$dataprovider分页部分放在下面$searchmodel，分页工作正常，但过滤器不起作用，反之亦然。
How can I have both filter and pagination working in the _form.php.
如何在 _form.php 中同时使用过滤器和分页。
Any solution will be greatly appreciated.
任何解决方案将不胜感激。
Thanks
谢谢

I have no experience with Yii2 but if it is similar than 1..
我没有使用 Yii2 的经验，但如果它类似于 1..
Why are you declaring dataProvidertwice? I imagine the first one is to be able to customize page size.
你为什么要声明dataProvider两次？我想第一个是能够自定义页面大小。
So what happens is you use one data provider to set pagination but then you pass a different one to the table.
所以会发生什么是你使用一个数据提供者来设置分页，然后你将另一个数据提供者传递给表。
Second I don't know how your model looks inside but..
其次，我不知道你的模型在里面看起来如何，但是..
Since I can see the search()method returns a dataProvider, you should change the pagination inside there.
由于我可以看到该search()方法返回 a dataProvider，因此您应该更改其中的分页。
Or I think you can change it right after the search()method returns the dataProviderlike:
或者我认为您可以在search()方法返回后立即更改它dataProvider：
$searchModel = New \app\models\ServiceChargesSearch();
$dataProvider = $searchModel->search(Yii::$app->request->queryParams);
$dataProvider->pagination->pageSize=5;
So you don't need the first instance of dataProviderthat you've declared before.
所以你不需要dataProvider你之前声明的第一个实例。
As for the filters I do not know how it exactly behaves your ServiceChargesSearch::searchfunction
至于过滤器，我不知道它究竟如何表现你的ServiceChargesSearch::search功能
But in Yii1 you normally:
但是在 Yii1 中，您通常会：
1) Define model 2) Fill it up with data from
$_GET3) Pass$model->search()to grid
1) 定义模型 2) 用数据填充它
$_GET3) 传递$model->search()到网格
If filters still not work you can provide code from the model.
如果过滤器仍然不起作用，您可以提供模型中的代码。

I do it this way in the controller:
我在控制器中这样做：
public function actionIndex()
{
$searchModel = new YourModels();
$dataProvider = $searchModel->search(Yii::$app->request->queryParams);
$dataProvider->pagination->pageSize = 10;
return $this->render('index', [
'searchModel' => $searchModel,
'dataProvider' => $dataProvider,
]);
}
