How to Create a Custom WooCommerce Settings Page for Bulk Discount Application with 400 Bad Request Error?
I am trying to create a custom settings page for my WooCommerce-based site to apply bulk discounts to products within specified categories and brands for a defined date range. However, I'm encountering an issue where the form redirects to /wp-admin/admin-post.php and returns a 400 Bad Request error.
I've enabled DEBUG mode, but there are no error messages displayed in the logs. The only indication of an issue is a 'WordPress Error' title in the browser.
Result Page;
Here are some details about what I've implemented:
- The form structure and fields
- How I'm processing the form submission
- Any relevant code snippets
