# Fix for Teacher Navigation Issue

## Problem
When teachers add a new student and then click the Home menu, they are redirected to the admin page instead of their teacher dashboard.

## Root Cause
Several student management pages had hardcoded navigation links that always pointed to `../index.php` (admin dashboard) regardless of the user's role.

## Solution
Updated the navigation sections in student management pages to check the user's role and redirect teachers to their dashboard (`../teachers/dashboard.php`) instead of the admin dashboard.

## Files Modified

1. **students/add.php** - Updated navigation bar to redirect teachers to their dashboard
2. **students/view.php** - Updated navigation bar to redirect teachers to their dashboard  
3. **students/edit.php** - Updated navigation bar to redirect teachers to their dashboard

## Code Changes
Changed the navigation links from:
```php
<a class="navbar-brand" href="../index.php">
<a class="nav-link" href="../index.php">
```

To:
```php
<a class="navbar-brand" href="<?php echo ($_SESSION['user_role'] == 'teacher') ? '../teachers/dashboard.php' : '../index.php'; ?>">
<a class="nav-link" href="<?php echo ($_SESSION['user_role'] == 'teacher') ? '../teachers/dashboard.php' : '../index.php'; ?>">
```

## Verification
The fix ensures that:
- Teachers are redirected to their dashboard when clicking Home
- Admins continue to be redirected to the admin dashboard
- The navigation works correctly across all student management pages

## Testing
Tested the following scenarios:
1. Teacher adds a new student and clicks Home - redirects to teacher dashboard
2. Admin adds a new student and clicks Home - redirects to admin dashboard
3. Teacher views student details and clicks Home - redirects to teacher dashboard
4. Teacher edits student information and clicks Home - redirects to teacher dashboard
