Yii2-activedataprovider doesn't fetch data

I use some $query->andFilterWhere(...) to create my query.

and can see the final query by echo $query->createCommand()->rawSql;

when I copy the final query and past it on phpmyadmin, 2 record fetched but no result found in ActiveDataProvider.

Where is the point that I miss that?!

============================================

This is my code:

    $query = Camera::find();
$post = Yii::$app->request->post();
$post2 = array_filter((array)$post);

if( count($post2) >0 ){
    foreach($post2 as $k=>$v){
        $query->andFilterWhere([ 'Like' , $k , $v ]);
    } 
}

if($post['State'] > 0){
    $branches = Branch::find()->joinWith('city')->where('state_id='.((int)$post['State']))->all();
    foreach( $branches as &$v){
        $v = $v->brch_id;
    }
    $query->andFilterWhere([ 'IN' , 'brch_id' , $branches ]);    
}

echo $query->createCommand()->rawSql;

$dataProvider = new ActiveDataProvider([
    'query' => $query,
]);

The problem was this loop:

foreach( $branches as &$v){
    $v = $v->brch_id;
}

I just replace it by:

$a = [];
foreach( $branches as $v){
    $a[] = (int)$v->brch_id;
}

and DONE, Solved!!!!! :|
