How do I display pagination in Yii2 GridView? - php

Question

I am getting my dataProvider from which I try to remove some models that don't meet the wanted criteria. This filter is not SQL related and therefore I can't apply it directly to the query. On my view the pagination links are displayed if I leave the dataprovider just as it was. But after I apply the filters to remove the unwanted models, the pagination links disappear. I have tried setting the pagination on my new dataProvider but nothing works.
Here's my code in the controller action:
$request = Yii::$app->request;
$search_model = new StaffEmploymentListViewSearch();
$data_provider = $search_model->search($request->queryParams);
$models = $data_provider->models;
for($k=0;$k<count($models);$k++)
{
if($models[$k]->employ === null){
unset($models[$k]);
}
}
$config = [
'pageParam' => 'page',
'pageSizeParam' => 'per-page',
'forcePageParam' => true,
'route' => null,
'params' => null,
'urlManager' => null,
'validatePage' => true,
'totalCount' => 5214,
'defaultPageSize' => 20,
'pageSizeLimit' => [
'0' => 1,
'1' => 50
],
'pagesize' => 20
];
$data_provider->setModels($models);
$data_provider->setPagination($config);
return $this->render('all-staff',[
'dataProvider' => $data_provider,
'searchModel' => $search_model
]);
Here's my search method:
$query = StaffEmploymentListView::find()
->SELECT([
'PAYROLL_NO',
'BIRTH_DATE',
"ADD_MONTHS(BIRTH_DATE, 70 * 12) AS RETIRE_DATE"
]);
// add conditions that should always apply here
$dataProvider = new ActiveDataProvider([
'query' => $query,
'sort' => false,
'pagination' => [
'pagesize' => 20,
],
]);
How do I go about doing this?

Answer 1

Try to use ArrayDataProvider
$query = StaffEmploymentListView::find()
->select([
'PAYROLL_NO',
'BIRTH_DATE',
"ADD_MONTHS(BIRTH_DATE, 70 * 12) AS RETIRE_DATE"
]);
$allModels = [];
foreach ($query->all as $staffEmployment)
{
if ($model->employ === null){
$allModels[] = $model;
}
}
$dataProvider = new ArrayDataProvider([
'allModels' => $allModels,
'pagination' => [
'pageSize' => 20,
],
'sort' => false
]);
return $this->render('all-staff',[
'dataProvider' => $data_provider,
'searchModel' => $search_model // ???
]);
