# Account Number & Username Fix - Summary

## Problem
The system was generating account numbers but storing them in the `username` field instead of the `acc_no` field. This caused confusion because:
- Account numbers were overwriting usernames
- Users couldn't login with their chosen username
- The `acc_no` column wasn't being populated

## Solution Applied

### 1. Updated Registration Form (`dashboard/new_account.php`)
- **Separated username and account number fields**:
  - `uname` field: User-chosen username (for login)
  - `acc_no` field: Auto-generated account number (10-digit random number)
  
- **Fixed duplicate field issue**: Removed the duplicate `uname` field that was causing the account number to overwrite the username

- **Updated validation**: Now checks for duplicate usernames AND account numbers separately

- **Added missing fields**: Added default values for `alt_phone`, `alt_email`, `ibf`, and `erm` fields

### 2. Updated Admin Class (`dashboard/admin/class.admin.php`)
- **Modified `create()` method**:
  - Added `username` column to INSERT statement
  - Maps `uname` parameter → `username` column (for login)
  - Maps `acc_no` parameter → both `uname` and `acc_no` columns (account number)

- **Modified `createsign()` method**: Applied same changes for consistency

### 3. Database Structure
The database already has these columns:
- `username` - For user login (user-chosen)
- `uname` - Account number (auto-generated)
- `acc_no` - Account number (auto-generated, duplicate of uname for compatibility)

## How It Works Now

### Registration Process:
1. Admin fills in the registration form
2. User enters their desired **username** (e.g., "john_doe")
3. System auto-generates a **10-digit account number** (e.g., "9312829110")
4. Both values are saved:
   - `username` = "john_doe" (for login)
   - `uname` = "9312829110" (account number)
   - `acc_no` = "9312829110" (account number)

### Login Process:
1. User enters their **username** (not account number)
2. System authenticates using the `username` field
3. Session stores the account number from `uname` field

## Email Notification
The welcome email now shows both:
- Username (for login)
- Account Number (for reference)

## Testing
To test the fix:
1. Go to the admin panel → Register New User
2. Fill in all fields including a unique username
3. Note the auto-generated account number
4. Submit the form
5. Check the database - verify:
   - `username` has the user-entered value
   - `uname` and `acc_no` both have the generated account number
6. Try logging in with the username (not account number)

## Files Modified
1. `dashboard/new_account.php` - Registration form
2. `dashboard/admin/class.admin.php` - User creation methods

## Notes
- Existing accounts may need migration if they have account numbers in the username field
- The `uname` field is kept for backward compatibility (many parts of the system reference it)
- Both `uname` and `acc_no` store the same account number value
