# Withdrawal Earning Feature - Implementation Summary

## ✅ Complete Implementation

### What Was Changed

#### 1. **Database Schema**
- Created `settings` table to store admin-configurable messages
- Added `withdrawal_message` setting with default value

```sql
CREATE TABLE settings (
    id INT AUTO_INCREMENT PRIMARY KEY,
    setting_key VARCHAR(100) NOT NULL UNIQUE,
    setting_value TEXT,
    updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
)
```

#### 2. **Dashboard Changes (dashboard.php)**

**Before:**
```html
<h3>Claim Returns</h3>
<button>Receive</button>
<button>Send</button>
<button>EXCHANGE</button>
```

**After:**
```html
<h3>Withdrawal Earning</h3>
<button onclick="showWithdrawalMessage()">
    Withdrawal Earning
</button>
```

#### 3. **Custom Modal Popup**
- Beautiful modal dialog with admin-configured message
- Yellow info icon
- "Withdrawal Notice" title
- Custom message from database
- "Got it" button to close
- Click outside to close
- Dark mode support

#### 4. **Admin Panel (admin.php)**
- New "Withdrawal Message Settings" section
- Textarea to edit the message
- "Update Message" button
- Real-time preview of current message
- Success/error notifications
