Install
This is the repository archive. It installs, but the folder name will carry the branch suffix and updates will not flow.
Install straight from GitHub with WP-CLI:
wp plugin install https://github.com/praveendias1180/woocommerce-birthday/archive/refs/heads/master.zipUpdates itself. It ships its own updater (Update URI header), so new versions appear under Dashboard → Updates.
WooCommerce Birthdays
The plugin lets you collect birthdays from the customers at the checkout page.
User Table with Birthdays
Next, it adds the customer as a user to WordPress as a 'coin-member'. (Removes the default role subscriber.) Then it adds a column to a user table to display the collected birthday.
Birthday Reminder Page
This table list the birthdays of 'coin-members'. This can be customized to filter specific month only. Also, WordPress Cron can be used to send emails automatically.
