How to make all items in stock?

Question

1C-Bitrix

Good afternoon.
I got an online store on Bitrix with 4000 products, all products are "out of stock",
In the product settings - trade catalog - Allow purchase in the absence of goods (including allowing a negative quantity of goods): NO.
How can I bulk-enable all items to "in stock" and allow a purchase with a negative quantity?

Answer 1

Something like this, you can make a better request, but it will do for once - this code will set the default value

\Bitrix\Main\Loader::includeModule('iblock');
\Bitrix\Main\Loader::includeModule('catalog');

$iblocksId = [2, 3];

$iterator = \Bitrix\Iblock\ElementTable::getList([
  'select' => ['IBLOCK_ID', 'ID'],
  'filter' => ['IBLOCK_ID' => $iblocksId, '!PRODUCT.CAN_BUY_ZERO' => 'D', '!PRODUCT.TYPE' => \Bitrix\Catalog\ProductTable::TYPE_SKU],
  'runtime' => [
    'PRODUCT' => [
      'data_type' => '\Bitrix\Catalog\ProductTable',
      'reference' => ['=this.ID' => 'ref.ID']
    ]
  ]
]);

$elements = [];
while($row = $iterator->fetch()) {
  $elements[] = $row;
}

foreach($elements as $element) {
  CCatalogProduct::Update($element['ID'], ['CAN_BUY_ZERO' => 'D']);	
}

echo 'Количество = '.count($elements);

$iblocksId - id-shnik infoblocks Catalog and Trade offers, if there are no trade offers, specify only the catalog ID
Then in the answers there the person threw off the screen, set the default settings
In the catalog component, PRICE_CODE must be specified
