# Scholarship-Based Fee Exemption Implementation

## Overview
This document describes the implementation of scholarship-based fee exemption functionality in the fee management system. Students marked with scholarship status ('yes') are automatically exempted from all fee payments.

## Changes Made

### 1. Fee Management Page (`fees/manage.php`)
- Updated the fee assignment logic to exclude students with scholarship status when assigning class-based fees
- Modified success messages to indicate that scholarship students are excluded
- Enhanced the recent fees display to show scholarship status for each student
- Updated the recent fees query to include scholarship information

### 2. Fee Collection Page (`fees/student_fees.php`)
- Modified the student search functionality to include scholarship information
- Updated the student display to show a "উপবৃত্তি" badge for scholarship students
- Implemented scholarship checks in the fee details retrieval:
  - If a student has scholarship status, the system returns a special response indicating exemption
  - The UI displays a message that the student is exempt from fees due to scholarship
- Enhanced the fee collection area to show appropriate messages for scholarship students

### 3. Database Queries
- Updated student queries to include the `scholarship` field
- Modified fee assignment queries to exclude scholarship students
- Enhanced fee retrieval queries to check scholarship status

## Functionality

### Fee Assignment
When assigning fees to a class:
1. The system retrieves all active students in the class
2. Students with `scholarship = 'yes'` are automatically excluded
3. Fees are only assigned to students with `scholarship = 'no'`
4. Success messages indicate the number of students who received fees (excluding scholarship recipients)

### Fee Collection
When collecting fees from a student:
1. Student search results show a "উপবৃত্তি" badge for scholarship students
2. When a scholarship student is selected, the system:
   - Checks the student's scholarship status
   - Displays a message indicating the student is exempt from fees
   - Prevents any fee collection actions
3. For regular students, the normal fee collection process continues

### Recent Fees Display
The recent fees section now:
- Shows scholarship status for each student
- Maintains all existing functionality for regular students
- Clearly indicates which students have scholarship exemptions

## Testing
The implementation has been tested to ensure:
1. Scholarship students are properly excluded from fee assignments
2. Scholarship students cannot have fees collected
3. Regular students continue to work as before
4. UI displays appropriate messages for both types of students

## Future Considerations
- Implement partial scholarship functionality (percentage-based fee reduction)
- Add scholarship expiration dates
- Create scholarship reporting features
- Add scholarship type categorization
