# Phase 2 Employee Salary Assignment - FIXES APPLIED

**Date:** 2026-02-16
**Status:** ✅ FIXED

---

## Issues Found and Fixed

### Issue 1: New Assignment Button Not Working
**Problem:** Button was using incorrect URL (`?action=new` without `id`)
**Fix:** Changed button to `?action=new&id=0` for proper routing
**File:** employee-salary-assign.php (line 111)

### Issue 2: Missing jQuery Library
**Problem:** jQuery was not loaded before other plugins, causing `$ is not defined` error
**Fix:** Added local jQuery from assets at line 292 before other vendor scripts
```html
<script src="assets/plugins/jquery/jquery.min.js"></script>
```
**Impact:** Fixed all JavaScript errors
**Note:** Using local jQuery instead of CDN for better reliability and offline support

### Issue 3: Employee Selection Missing in New Assignment Form
**Problem:** New assignment form had no way to select employee
**Fix:** 
- Added `employeeSelectDiv` for new assignments
- Added `employeeInfoDiv` for edit mode
- Both DIVs toggle based on mode
**File:** employee-salary-assign.php (lines 160-188)

### Issue 4: Employee ID Not Captured for New Assignments
**Problem:** saveAssignment() was trying to send `null` as employee_id
**Fix:**
- Added hidden field `selectedEmployeeId`
- Added onEmployeeSelected() handler
- Properly pass employee_id to API
**File:** employee-salary-assign.php (lines 439-458, 543-566)

### Issue 5: Mode Detection Not Working
**Problem:** Page couldn't distinguish between "new" and "edit" modes
**Fix:**
- Updated JavaScript condition to check `?action=new`
- Changed `assignmentId` logic to check if `id === 0`
**File:** employee-salary-assign.php (line 443)

### Issue 6: Toast Notifications Using alert()
**Problem:** Using `alert()` for notifications (bad UX)
**Fix:** Implemented proper Bootstrap toast notifications
**File:** employee-salary-assign.php (lines 642-664)

### Issue 7: Error Messages Not Showing
**Problem:** Error messages had no display logic
**Fix:** Added `.show()` and `.hide()` for all error fields
**File:** employee-salary-assign.php (line 584)

### Issue 8: Missing Employee Loading for Dropdowns
**Problem:** New assignment form had no employees to select
**Fix:** Added `loadEmployeesForSelection()` function
**File:** employee-salary-assign.php (lines 462-479)

### Issue 9: Form Validation Logic Missing
**Problem:** No validation before API calls
**Fix:** 
- Added required field validation
- Check employee selection for new assignments
- Clear errors before validation
**File:** employee-salary-assign.php (lines 584-618)

### Issue 10: Employee ID Not Populated for Edit Mode
**Problem:** Edit mode wasn't storing employee ID for updates
**Fix:** Added `$('#selectedEmployeeId').val(data.employee_id);`
**File:** employee-salary-assign.php (line 472)
