I have a Laravel (API + Next.js frontend) eCommerce/Service selling website. There are two tasks that need to be fixed: 1. Phone Number Must Be Required During Signup Add phone number as a required field at user signup. Validate phone number on backend (Laravel API). Save the phone number into the users table. Phone must be visible in: Admin → Users → User Detail And auto-fill into user profile "About / Contact info" on frontend. Important: Phone number field currently exists in frontend, but backend is not storing or validating it. Need to fix this. 2. Fix Logged-in User PayPal Checkout Flow Right now, the PayPal checkout still asks for email & password even when the user is already logged in. I want this fixed: Correct Behavior Should Be: If user is logged in: Use logged-in user’s email & phone automatically. User must only enter message + seller account ID → then go directly to PayPal. No email/password prompts again. If user is not logged in (guest): Ask for email + phone + message before redirecting to PayPal.
