PHP Snippet: Programmatically Set The Shipping Class For All WooCommerce Products

Note: you will need to know the shipping class ID before using the code below. There are two ways to find the shipping class ID in WooCommerce:

1. WooCommerce Settings

• This method only works if you have already created the shipping class.
• Go to WooCommerce > Settings > Shipping > Shipping Classes.
• You’ll see a list of your shipping classes with their names and slugs. However, the ID won’t be displayed directly on this page.
• Use your browser “inspect” tool as described here https://www.businessbloomer.com/woocommerce-disable-free-shipping-if-cart-has-shipping-class/#woocommerce-how-to-find-shipping-class-id to retrieve the ID.

2. Edit Product Page

• This method involves using your browser’s developer tools once again.
• Open the Edit Product page for any product.
• Locate the Product data meta box and navigate to the Shipping tab.
• Right-click on the Shipping class dropdown element and select Inspect (or Inspect Element).
• In the developer tools window, look for the value attribute associated with the selected shipping class option. This value is the shipping class ID.
