OroInventoryBundle

OroInventoryBundle enables the OroCommerce back-office users to specify and manage current inventory levels for every product and set up a threshold for the low inventory status. The low inventory highlights functionality adds an inventory status message to products when their quantity drops below the value defined in Low Inventory Threshold. Reaching the defined Low Inventory Threshold level triggers a warning message to the buyer in the storefront.

Configuration

product_inventory_options:
    children:
        - oro_inventory.highlight_low_inventory
        - oro_inventory.low_inventory_threshold

The oro_inventory.highlight_low_inventory option is used to enable highlighting low inventory for products. Contains the true or false values. When the quantity of the product is lower than or equals the value of the oro_inventory.low_inventory_threshold option, then the product gets highlighted as low inventory in the storefront.

Options

Two new options are added for products and categories. These options are highlightLowInventory and lowInventoryThreshold. These options help configure options for each category or product individually. By default, these options use the value from the system configuration. To check the currently configured fallback for product or category, use Oro\Bundle\EntityBundle\Fallback\EntityFallbackResolver.

Example:

$lowInventoryThreshold = $this->entityFallbackResolver->getFallbackValue(
            $product,
            'lowInventoryThreshold'
        );

Listeners

ProductDatagridListener

This listener contains the method that adds information about low inventory to the product grid.

onPreBuild

This method is called before the grid is built. It adds a new low_inventory property to the grid configuration that enables adding the low inventory information to the property and thus, displaying it in the layout when required.

onResultAfter

This method is called when we execute query and have data result. This method uses the logic of LowInventoryProvider . It adds information about the low inventory option for each product in the collection. It also adds a boolean value to low_inventory which will then be used in the layout. The following is an example of using low_inventory in the layout of the product grid:

{% block _product_datagrid_row__product_low_inventory_label_widget %}
    {% if (product.low_inventory) %}
        <div class="grid">
            <div class="grid__row">{{ "oro.inventory.low_inventory.label"|trans }}</div>
        </div>
    {% endif %}
{% endblock %}

LowInventoryCheckoutLineItemValidationListener

The Oro\Bundle\InventoryBundle\EventListener\LowInventoryCheckoutLineItemValidationListener class. This listener contains a method that checks low inventory for line item products and adds a warning message if a product has low quantity.

onLineItemValidate

public function onLineItemValidate(LineItemValidateEvent $event)

It validates the product from the line item and adds a warning message if this product has a low inventory level.

Providers

LowInventoryProvider

The Oro\Bundle\InventoryBundle\Inventory\LowInventoryProvider class.

This class contains a method that helps you quickly get information about low quantity for the current product or product collection.

isLowInventoryProduct

public function isLowInventoryProduct(Product $product, ProductUnit $productUnit = null)

This method returns information about the low inventory status of the current product. It returns true if the quantity of the product is less than the lowInventoryThreshold option. It returns false if the quantity of the product is greater than the lowInventoryThreshold option, or if the highlightLowInventory is not checked.

isLowInventoryCollection

/**
  * Returns low inventory flags for product collection.
  * Will be useful for all product listing (Catalog, Checkout, Shopping list)
  *
  * @param array $data products collection with optional ProductUnit's
  * [
  *     [
  *         'product' => Product entity,
  *         'product_unit' => ProductUnit entity (optional),
  *         'highlight_low_inventory' => bool (optional),
  *         'low_inventory_threshold' => int (optional)
  *     ],
  *     ...
  * ]
  *
  * @return [product id => is low inventory, ...]
  */
 public function isLowInventoryCollection(array $data)

It works in the same way as the isLowInventoryProduct method, but has differences in taken up arguments and returned values. This method takes an argument as an array of the Product entity and ProductUnit entity entities and returns an array of product ids with a boolean result. true is returned if the quantity of the product is less than the lowInventoryThreshold option. false is returned if the quantity of the product is greater than the lowInventoryThreshold option, or if highlightLowInventory is not checked.

Twig

To to check low inventory for a specific product in Twig templates, the oro_is_low_inventory_product Twig function is used. The following example illustrates how to use this function/how this function is used:

{% if (oro_is_low_inventory_product(mainProduct)) %}
        <div class="product-low-inventory">{{ "oro.inventory.low_inventory.label"|trans }}</div>
{% endif %}

Validators

LowInventoryCheckoutLineItemValidator

The Oro\Bundle\InventoryBundle\Validator\LowInventoryCheckoutLineItemValidator class. This class contains a method that returns a message if a product has low quantity.

getLowInventoryMessage

public function getLowInventoryMessage(LineItem $lineItem)

When a product is marked as low inventory, the method returns a string message. Otherwise, it will return false. This method uses the logic from LowInventoryProvider.
