How to set random quantity for all products in Bitrix?

Question

1C-Bitrix

Warehouse accounting is disabled.
Import of goods. The quantity column is missing.
Import again for a long time and add a column.
GOODS NOT SIMPLE, but with offers.
You need to run some code, like in php_interface, which would sort through all product offers from the Products Offers catalog with a time step, and set a random number from 1 - 10.
The delay is about 20 seconds. Since the hosting has a time limit for the execution of the source code.

Answer 1

I would do all this on the crown, this can bypass the limits

<?
// увеличеваем лимиты сервера
@set_time_limit(30000);
ini_set('max_execution_time', 30000);


// грузим классы Битрикса
require_once($_SERVER['DOCUMENT_ROOT'] . "/bitrix/modules/main/include/prolog_before.php");
Cmodule::IncludeModule('catalog');
Cmodule::IncludeModule('iblock');

$$IBLOCKID = ''; // Задем Иблок с товармыми предложениями

// проходимся по всем товарам
$arFilter = Array("IBLOCK_ID"=>$IBLOCKID, "ACTIVE_DATE"=>"Y", "ACTIVE"=>"Y", 'INCLUDE_SUBSECTIONS'=>'Y', );
$res = CIBlockElement::GetList(Array(), $arFilter, false, false, array());
while ($ob = $res->GetNextElement())
{
    $arr = $ob->GetFields();
    // задаем кол-во рандомное
    $kolvo =  rand(1,11);
    // вставляем его
    $arPrise = array('QUANTITY' => $kolvo);// зарезервированное количество
    CCatalogProduct::Update($arr['ID'], $arPrise);
    
}

echo 'Скрип сработал  все хорошо (:';

?>

Answer 2

I don’t know how for offers, but for ordinary goods it will work accurately and much faster than the standard Bitrix mechanism. This is if there is 1 directory on the site, if there are several, then you need additional. filtration

AddEventHandler('catalog', 'OnSuccessCatalogImport1C', 'customCatalogImportStep');

/**
 * Устанавливаем случайное кол-во товаров
 * @param $arParams
 * @param $arFields
 */
function customCatalogImportStep($arParams, $arFields) {
    global $DB;
    $DB->Query('UPDATE b_catalog_product SET AVAILABLE = "Y", QUANTITY = FLOOR(1 + RAND() * 10);');
}
