How The Functions Work

Certainly, let’s provide concise explanations for each function without including the code snippets:

Enqueue Datepicker Scripts and Styles

This function enqueues the jQuery UI Datepicker script and its associated CSS file, ensuring they are loaded in the WordPress admin area. Modify URLs or add additional scripts/styles as needed.

Save Custom Meta Box Data

This function saves custom meta box data for a product, checking if the “Add Expiration Date?” checkbox is checked. It saves ‘yes’ to ‘_add_expiration_date’ and the entered expiration date to ‘_expiration_date’. Modify keys or add more fields as needed.

Add Custom Fields to Product Data General Tab

This function adds custom fields (e.g., “Add Expiration Date?” checkbox and datepicker) to the Product Data General tab. Modify the structure of fields, add more, or rearrange their order based on preferences.

Display Custom Fields on Product Page

This function displays custom fields (product name, date of purchase, and expiration date) on the single product page. Customize the HTML structure or modify displayed fields based on design preferences.

Add Custom Fields to Order Email

This function adds custom fields to the order email, checking if the “Add Expiration Date?” checkbox is checked for each product. Modify displayed information or customize the HTML structure of the email.

Modifying/Extending The Code

The code snippets are modular, allowing easy modification or extension based on specific requirements.

If you need to add more fields, change labels, or adjust display logic, you can do so by understanding each function’s structure and making necessary modifications.

Always make backups and test changes in a safe environment.
