$aFilter = array();

if (getString('action')=='filter')
{

    $aFilter['user_name']=getString('user_name');
    $aFilter['user_surname']=getString('user_surname');
    $aFilter['order_id']=getString('order_id');
    $aFilter['email']=getString('email');
    $aFilter['date_from']=getString('date_from');
    $aFilter['date_to']=getString('date_to');
    //$aFilter['type_id']=getNumber('type_id');
    $$oDirectHTML->SetVar($aFilter);

    array_merge($aFilterParams, $aFilter);


}

You must to assign the result of array_merge to the $aFilter variable or to the $aFilterParams variable, depending on your needs:

$aFilter = array_merge($aFilterParams, $aFilter);
