[5.x]: How to create a Product in Craft Commerce 5 (Controller)

[alex-brukhty]

Please help, Craft Commerce 5 have new Inventory logic and I can figure out how to programmatically create new Products with one variant and 1 item in stock. Looks like after new Variant element is getting saved InventoryItem is not being created.
and $variant->getInventoryItem() gives null.

$product = new Product([
    'title' => 'title',
    'typeId' => 2
]);

Craft::$app->elements->saveElement($product);

$variant = new Variant([
    'inventoryTracked' => true,
    'isDefault' => true,
    'primaryOwnerId' => $product->id,
]);

$variant->setBasePrice($prod->price);

Craft::$app->elements->saveElement($variant);

$inventoryItem = $variant->getInventoryItem();
$inventoryLocation = Plugin::getInstance()->getInventoryLocations()->getInventoryLocationById(1);
$updateInventoryLevels = UpdateInventoryLevelCollection::make();
$updateInventoryLevels->push(
    new UpdateInventoryLevel([
        'type' => 'available',
        'updateAction' => InventoryUpdateQuantityType::SET,
        'inventoryItem' => $inventoryItem,
        'inventoryLocation' => $inventoryLocation,
        'quantity' => 1,
        'note' => 'New',
    ])
);

Plugin::getInstance()->getInventory()->executeUpdateInventoryLevels($updateInventoryLevels);

$product->setVariants([$variant]);

Craft::$app->elements->saveElement($product);

made it work by re-querying variants again after creating new and saving as above.

foreach (Variant::find()->id($variantIds)->all() as $variant) {
  $updateInventoryLevels = UpdateInventoryLevelCollection::make();
  $updateInventoryLevels->push(
    new UpdateInventoryLevel([
      'type' => 'available',
      'updateAction' => InventoryUpdateQuantityType::SET,
      'inventoryItem' => $variant->getInventoryItem(),
      'inventoryLocation' => Plugin::getInstance()->getInventoryLocations()->getInventoryLocationById(1),
      'quantity' => 1,
      'note' => 'New',
    ])
  );
  Plugin::getInstance()->getInventory()->executeUpdateInventoryLevels($updateInventoryLevels);
}

Hi @alex-brukhty it would be great if you could share the full code or process. I was trying it but still getting error craft\commerce\services\Inventory::getInventoryItemById(): Argument #1 ($id) must be of type int, null given, called in /var/www/html/vendor/craftcms/commerce/src/services/Inventory.php on line 79

This is the full code, a bit repetitive use of saveElement but I think it's only one way to make it work.

$product = new Product([
    'title' => 'product name',
    'typeId' => 2,
]);

Craft::$app->elements->saveElement($product);

$variant = new Variant([
    'inventoryTracked' => true,
    'isDefault' => true,
    'primaryOwnerId' => $product->id,
]);
$variant->setBasePrice(99.99);
Craft::$app->elements->saveElement($variant);

$product->setVariants([$variant]);
Craft::$app->elements->saveElement($product);

$variant = Variant::find()->id($variant->id)->one();
$commercePlugin = Plugin::getInstance();
$updateInventoryLevels = UpdateInventoryLevelCollection::make();

if ($inventoryItem = $commercePlugin->getInventory()->getInventoryItemByPurchasable($variant)) {
    $firstInventoryLevel = $commercePlugin->getInventory()->getInventoryLevelsForPurchasable($variant)->first();
    if ($firstInventoryLevel && $firstInventoryLevel->getInventoryLocation()) {
        $updateInventoryLevels->push(new UpdateInventoryLevel([
            'type' => InventoryTransactionType::AVAILABLE->value,
            'updateAction' => InventoryUpdateQuantityType::SET,
            'inventoryItem' => $inventoryItem,
            'inventoryLocation' => $firstInventoryLevel->getInventoryLocation(),
            'quantity' => 1,
            'note' => '',
        ]));
    }
}

if ($updateInventoryLevels->count() > 0) {
    $commercePlugin->getInventory()->executeUpdateInventoryLevels($updateInventoryLevels);
}

Craft::$app->elements->saveElement($variant);
