The WC_Product class explained

The ≈ class in WooCommerce is an abstract class, serving as a blueprint for other more specific product classes. It is not designed to be instantiated as an object but provides essential properties and methods shared by various product types. Different product types, such as simple, variable, grouped, and external products, inherit from WC_Product, extending its functionalities to cater to their specific characteristics.

The most common classes that inherit from WC_Product include:

  • WC_Product_Simple: Represents a basic, single item without variations.
  • WC_Product_Variable: Handles products with multiple variations, such as size, color, or other attributes.
  • WC_Product_Grouped: Manages a collection or group of related products sold together.
  • WC_Product_External: Represents products listed externally, redirecting customers to another website for purchase.

Each of these classes extends the WC_Product abstract class, inheriting its core functionalities while introducing specialized features tailored to their respective product types. As a result, these classes share common methods and properties from the WC_Product class, and this article will delve deeper into their specifics.

Creating an instance of WC_Product class

As mentioned above, the WC_Product class is not designed to be instantiated. However, you can create an instance using one of its inheriting classes or use one of the WooCommerce methods to create the instance for you.

Creating an instance for existing (persisted) products

If you need to create a WC_Product object for an existing product stored in the database, the easiest way is to use the wc_get_product() function. This function accepts a product ID and searches the database to find a product with the given ID. If a product is found, it automatically returns an instance using the correct subclass depending on the product type.

Here is an example using a simple product:

Creating an instance for new product objects

If you need to create an instance manually, you can directly instantiate the WC_Product subclasses. Here is an example of instantiating a simple product object. In this example, we also set the name of the product:

The following example shows how to create an instance for a variable product.
