Magento 2.1 Cron Job – How to Update Product Stock

cronmagento-2.1magento2skustock

I need to be able to programmatically update product stock in my Cron job. I have an array that contains both the SKU of the product needing updating and the Stock value of that product. How can I select a product by SKU and then update the stock?

I'm not sure about your data array which contains the SKU product and Stock value. So, I will use simple data.

We can update product stock via API:

vendor/magento/module-catalog-inventory/Model/StockRegistry.php

vendor/magento/module-catalog/Model/ProductRepository.php

        $objectManager = \Magento\Framework\App\ObjectManager::getInstance();

        //Our sample values
        $sku = '100098';
        $stockValue = 5;

        $productRepository = $objectManager->create('Magento\Catalog\Api\ProductRepositoryInterface');
        $stockRegistry = $objectManager->create('Magento\CatalogInventory\Api\StockRegistryInterface');

        //Load product by SKU
        $product = $productRepository->get($sku);
        //Need to load stock item
        $stockItem = $stockRegistry->getStockItem($product->getId());
        $stockItem->setData('qty',$stockValue); //set updated quantity

        //$stockItem->setData('manage_stock',$stockData['manage_stock']);
        //$stockItem->setData('is_in_stock',$stockData['is_in_stock']);
        //$stockItem->setData('use_config_notify_stock_qty',1);

        $stockRegistry->updateStockItemBySku($sku, $stockItem);

* = always. It is a wildcard for every part of the cron schedule expression.

So * * * * * means every minute of every hour of every day of every month and every day of the week.

 * * * * *  command to execute
 ┬ ┬ ┬ ┬ ┬
 │ │ │ │ │
 │ │ │ │ │
 │ │ │ │ └───── day of week (0 - 7) (0 to 6 are Sunday to Saturday, or use names; 7 is Sunday, the same as 0)
 │ │ │ └────────── month (1 - 12)
 │ │ └─────────────── day of month (1 - 31)
 │ └──────────────────── hour (0 - 23)
 └───────────────────────── min (0 - 59)

The nice drawing above is provided by wikipedia

An other example:

0 * * * * -this means the cron will run always when the minutes are 0 (so hourly)
0 1 * * * - this means the cron will run always at 1 o'clock.
* 1 * * * - this means the cron will run each minute when the hour is 1. So 1:00, 1:01, ...1:59.

This code inserts the cron job into cron_schedule table:

$job_code='my_great_job_code';
/* */
$time = time(); // or time()+60 if you want...
$date = strftime('%Y-%m-%d %H:%M:00', $time);
/* */
$schedule = Mage::getModel('cron/schedule');
$schedule->setCreatedAt(strftime('%Y-%m-%d %H:%M:00', time()));
$schedule->setScheduledAt($date);
$schedule->setStatus(Mage_Cron_Model_Schedule::STATUS_PENDING);
$schedule->setJobCode($job_code);
$schedule->save();
