Batch request, how to get the next 50 requests from bitrix24 in php?

Question

Bitrix24

I need the list method to give me every 50 next requests, I write like this:

for($i = 0; $i < 10; $i++){
    $arParams['get_elapsed_'.($i+1)] = [
      'method' => 'task.elapseditem.getlist',
      'params' => [
        'order' => ["ID" => "ASC"],
        'filter' => [">=CREATED_DATE" => $dateFrom,"<CREATED_DATE" => $dateTo],
        'select' => ['ID','TASK_ID','COMMENT_TEXT','MINUTES'],
        'more' => true,
        'next' => ($i+1)*50
      ]
    ];
  }

and get error Param #4 (params) for method ctaskelapseditem::getlist() expected to be of type "array", but given something else.; 256/TE/WRONG_ARGUMENTS ,
although this scheme seems to work on ordinary getters, tell me how to take every 50 next results

Answer 1

use the description, there you need to use two parameters to control the size of the list and the current page:

"PARAMS" => array('NAV_PARAMS' => array(    // Постраничка
        "nPageSize" => 2,                        // по 2 элемента на странице
        'iNumPage' => 2                        // страница номер 2
    )),
