ActiveDataProvider display value yii2

i just want to know that is it possible to display data of $dataprovider independent of any gridview.

Like if the $dataprovider contains value of a particular query result than it will be stored as array in that.

So how can i call only one value from $dataprovider

For example my $dataprovider contains value of all select * from user where status=10 so is it possible just to display $dataprovider->user>name just first record.

Thank you

Solution

  • You can certainly access $dataProvider->models as suggested by scaisEdge and get the single model you need, but that is not very efficient, because it executes the query and retrieves all models only to be discarded later.

    You can, however, get access to dataProvider's query object, and with it get the single model you need.

    $newQuery = clone $dataProvider->query;
$model = $newQuery->limit(1)->one();

    Cloning the query is not necessary if it's ok to modify the dataProvider (if you don't use it anywhere else).

    UPDATE:

    $this->title = isset($dataProvider->models[0]->name) ? $dataProvider->models[0]->name : 'empty result';
