**Status:** ✅ **COMPLETELY FIXED**

## ✨ What We Fixed & Created

### 1. ✅ Login Error Resolution
- **Problem:** Member login was throwing errors
- **Solution:** Updated `auth/login.php` with proper validation, JSON responses, and session management
- **Result:** Login now works perfectly with redirect to dashboard

### 2. ✅ Redirect After Login
- **Problem:** Users were staying on index.php instead of going to member dashboard
- **Solution:** Updated JavaScript handlers to properly parse JSON and redirect
- **Result:** Users now correctly redirect to `member-dashboard.php` after successful login

### 3. ✅ Hide Login/Register Buttons After Login
- **Problem:** Login and register buttons stayed visible even after login
- **Solution:** Added conditional PHP logic in header to check session state
- **Result:** Header now displays different buttons based on login status

### 4. ✅ Show User Profile After Login
- **Problem:** No indication that user is logged in
- **Solution:** Added user profile dropdown showing:
  - User's name with avatar icon
  - Quick links: Dashboard, Appointments, Shop, Logout
- **Result:** Logged-in users see professional profile dropdown in header

## 📞 Support & Troubleshooting

### Common Questions

**Q: Where do I test the login?**  
A: Go to `http://localhost/fitness/` and click Login/Register

A: Create one! Just click Register and fill the form

**Q: Where is the dashboard?**  
A: At `member-dashboard.php` (auto-redirected after login)

**Q: Where are users stored?**  
A: In database table `users` (created by setup-database.php)

**Q: How do I modify the UI?**  
A: Edit the modals in `index.php` (search for "loginModal" and "registerModal")

**Q: How do I add new user fields?**  
A: 1. Add column to users table, 2. Add form field to register form, 3. Update auth/register.php

### Troubleshooting

**Problem:** Getting "table doesn't exist"  
**Solution:** Run `setup-database.php` once to initialize database

**Problem:** Login says "invalid password" but credentials seem correct  
**Solution:** Passwords are case-sensitive, double-check typing

**Problem:** Not redirecting to dashboard after login  
**Solution:** Check browser console for errors, verify member-dashboard.php exists

**Solution:** Verify `auth/logout.php` exists and has proper session_destroy()
