Yii2, why doesn't search model work?

Question

Yii

With the help of GII, CRUD was created. The search model, controller, and views have been created. In the controller, in actionIndex (read) the following code:

$searchModel = new ProductSearch();
$dataProvider = $searchModel->search(Yii::$app->request->queryParams);

return $this->render('index', [
        'searchModel' => $searchModel,
        'dataProvider' => $dataProvider,
]);

Those. As far as I understand, by passing parameters to search() we will filter. I pass the parameters (I check Yii::$app->request->queryParams, there are parameters in it, everything is OK, for example id=2, type=mfu), however, the dataProvider displays ALL products, not by filter. What am I doing wrong?

Answer 1

How should it work.
Can you please provide more model code and search model code.
Most likely, you have incorrectly described search conditions in your search model, or you are trying to use non-existent fields.
