In this tutorial, we will explore how to add a custom function to enhance the functionality of your WooCommerce store. Specifically, we will focus on two different code snippets that utilize filter hooks to introduce conditional checks and modify the behavior of the cart and product purchasability.
The first code snippet utilizes the woocommerce_add_to_cart_validation filter hook, allowing us to customize the validation process when a product is added to the cart. We will learn how to implement conditional checks based on product categories and user login status. By leveraging this code, we can display error notices and prevent certain products from being added to the cart, providing a tailored purchasing experience for your customers.
The second code snippet centers around the woocommerce_is_purchasable filter hook, which enables us to control the purchasability of products. Through conditional checks based on product categories and user login status, we can dynamically determine whether a product is eligible for purchase or not. By understanding this code, you will gain the ability to customize the purchasability of specific products and restrict access as needed.
By following this tutorial, you will enhance your understanding of filter hooks in WooCommerce and learn how to apply them to add conditional checks and modify the cart and product behavior. Let’s dive in and unlock the potential of your WooCommerce store with these powerful custom functions.
The difference between the two codes can be summarized as follows:
Code 1:
Using the woocommerce_add_to_cart_validation filter hook, this code modifies the validation process when a product is added to the cart. It checks if the product belongs to specific categories (gekoelde-bier or bierkoerier) and verifies if the user is not logged in. If both conditions are met, it displays an error notice and prevents the product from being added to the cart.
Code 2:
Using the woocommerce_is_purchasable filter hook, this code determines whether a product is purchasable or not. It checks if the product belongs to specific categories (gekoelde-bier or bierkoerier) and verifies if the user is not logged in. If both conditions are met, it sets the $is_purchasable variable to false, indicating that the product is not purchasable.
In summary, the first code snippet focuses on validating the addition of a product to the cart, while the second code snippet determines the purchasability of a product. Both snippets utilize different filter hooks and serve different purposes based on their specific context within the WooCommerce functionality.
