# 🚀 Services Database Integration - Quick Reference

## What Changed?

**Before**: Services hardcoded in PHP (page requires code edits to change)
**Now**: Services stored in database (changes update instantly)

---

## ⚡ Quick Start

### 1️⃣ Initialize Database
```
Visit: http://localhost/fitness/setup-database.php
Creates: services table
Time: < 5 seconds
```

### 2️⃣ View Services Page
```
Visit: http://localhost/fitness/services.php
Auto-loads: 6 sample services on first visit
Time: Instant
```

### 3️⃣ Make Changes
Edit services directly in database - they appear immediately on website!

## 📊 Database Fields

```
services table:
├── id (number)
├── name (text) - "Gym Training"
├── description (long text)
├── price (money) - 49.00
├── duration (text) - "1 month"
├── icon (emoji) - 🏋️
└── status (active/inactive)
```

---

## 🎯 Common Tasks

### Add New Service
```sql
INSERT INTO services (name, description, price, duration, icon, status) 
VALUES ('Yoga', 'Flexible yoga classes...', 40, '1 session', '🧘', 'active');
```

### Change Price
```sql
UPDATE services SET price = 55.00 WHERE name = 'Personal Training';
```

### Hide Service (Don't Delete!)
```sql
UPDATE services SET status = 'inactive' WHERE id = 2;
```

### Show Hidden Service
```sql
UPDATE services SET status = 'active' WHERE id = 2;
```

### View All Services
```sql
SELECT * FROM services WHERE status = 'active';
```

## 📱 How It Works on Website

1. User visits `/services.php`
2. PHP queries database: `SELECT * FROM services WHERE status = 'active'`
3. Services loop displays each service
4. Services update in real-time when database changes

## 🆘 If Something's Wrong

| Issue | Solution |
|-------|----------|
| No services showing | Visit setup-database.php then refresh services.php |
| Price not updating | Clear browser cache (Ctrl+F5) |
| Database error | Check XAMPP MySQL is running |
| Duplicates appearing | Delete duplicate rows in database |
| Service won't hide | Set status to 'inactive' (don't delete) |
