Database Check: As mentioned before, you must run this in your database (e.g., phpMyAdmin) so it stops looking for a slug: ALTER TABLE courses DROP INDEX slug; (If you don't do this, MySQL might still throw an error if it finds a duplicate value in that column). Once you replace the method with the one above and delete the helper function at the bottom, the undefined method error will disappear. Does it work now?
Database-Code Sync: Your form now submits values that explicitly exist within your database constraints, clearing out the truncation warnings. Correct UI Badges: Your instructor catalog grid will now clearly read and highlight your existing database rows (approved for your Full Stack Web Development and React Native course rows) with pristine, glowing badges.
