Question

What data must be sended to dataprovider?

In my controller:

public function actionIndex() {
    $searchModel  = new UserSearch();
    $dataProvider =         


        

Answer 1

how send data to _single.php ? Here is how, use $viewParams

$viewParams public property array $viewParams = []

Additional parameters to be passed to $itemView when it is being rendered. This property is used only when $itemView is a string representing a view name.

echo ListView::widget( [
    'dataProvider' => $dataProvider,
    'viewParams'=>['name'=>'My Name is Stefano'], //acccessed in view as $name with value 'My Name is Stefano'
] );
