Yii2 first and last items in the ListView - php

Question

I have a typical ListView widget in a view as follows:
public function actionView($id)
{
$model = $this->findModel($id);
$dataProvider = new \yii\data\ActiveDataProvider(['query' => \app\models\Verses::find()->where(['sura_id' =>$id])->with('sura')]);
return $this->render('view', [
'model' => $model,
'dataProvider' => $dataProvider,
]);
}
In the view a list of Verses model is rendered and the pager of the ListView is available too.
I want to add some details to the page title. Those details are data from the first and last records of the Verses model rendered in the list.
I have tried to use min() and max() PHP functions to get the first and the last records in the view as follows:
$min = min($model->verses);
echo $min->verse_id;
However, it returns the ultimate first record regarding-less the current pager page. In other words, it does not return the verse_id value of the first item of the list.
Is there any way to get the first, last or even a specific nth item of the ListView?

Answer 1

You should simply try :
$models = $dataProvider->getModels();
$first = reset($models);
$last = end($models);
Read more about reset and end.

Answer 2

You could access to the models array of dataProvider a get the firts and the last
public function actionView($id)
{
$model = $this->findModel($id);
$dataProvider = new \yii\data\ActiveDataProvider(['query' => \app\models\Verses::find()->where(['sura_id' =>$id])->with('sura')]);
$first = $dataProvider['models'][0];
$last = $dataProvider['models'][$dataProvide['totalCount']-1];
or you can use
$myModels = $dataProvider->gestModels();
$first = myModels[0];
$last = myModels[$dataProvide['totalCount']-1];
and for the page you can use count instead of total count
return $this->render('view', [
'model' => $model,
'dataProvider' => $dataProvider,
]);
}
