Many payments in WooCommerce just fail because a credit card wasn’t updated recently when WooCommerce Subscriptions or another plugin tried to bill the account. It’s better if this issue is avoided whenever possible.

It’s way better to inform your customers that their card is about to expire.

I tried several WooCommerce methods and functions to pull the expiration month and year from an order but none of them worked, so unfortunately I had to use a direct SQL query and pull the info for the database and not via official functions. If any of the readers knows a better way to do this let me know. It seems WooCommerce stores the expiration month and year in these db tables: DB_PREFIX_woocommerce_payment_tokens and DB_PREFIX_woocommerce_payment_tokenmeta

The woocommerce_payment_tokenmeta table is more interesting as it contains the expiry_month and expiry_year information for a given payment payment method.

Note: not all payment gateways support so called tokenization where the credit card is stored.

What is Credit Card Tokenization?

Credit card tokenization is a security method used to protect your credit card information. When you enter your credit card number on a website or app, tokenization replaces your real credit card number with a random set of numbers and letters. This replacement is called a "token". The token is like a secret code. It can be used by the website or app to process your payments, but it doesn't reveal your actual credit card number.

Showing the message

The code below can be inserted into functions.php or in a custom WordPress plugin. Always backup the files before editing them! You can duplicate them under a different name but keep the same extension though and/or download them on your computer.

Do make sure you only copy the code without the opening php tag <?php if it's appending to an existing file or keep it if you're adding to a brand new file.

The code will start displaying an error message wen the credit card is about to expire in fewer than 90 days or if it has expired already.

The message this code will show will look similar to this one but the calculated days will be shorter of course
