How to make pagination in Bitrix in your component?

Question

1C-Bitrix

There is an infoblock with elements. Can you please tell me how to make pagination in the development of your component? It is possible some elementary example which will break elements on 20 elements. If we take the standard news.list component, we'll go to hell to catch what we need and use it in our component.

Answer 1

If we take the standard component news.list - we’ll catch the hell out of there

See the news.line component. It is simple and contains chunking.
According to the navigation itself, everything is written here (D7 core): https://dev.1c-bitrix.ru/learning/course/index.php...
If for some reason you need the old style:

$arFilter = Array("IBLOCK_ID" => 22, "ACTIVE_DATE" => "Y", "ACTIVE" => "Y");
$res = CIBlockElement::GetList(Array(), $arFilter, false, array("nPageSize" => 20), Array());
$res->NavStart(0);
while ($ob = $res->GetNextElement()) {
  $product_fields_list = $ob->GetFields();
  $product_props_list = $ob->GetProperties();
  
  echo "<pre>";
  print_r($product_fields_list);
  echo "</pre>";
}

$navStr = $res->GetPageNavStringEx($navComponentObject, "Страницы:", ".default");
echo $navStr;
