# Onboarding Tracker - Implementation Summary
**Date:** March 12, 2026
**Status:** ALL FEATURES COMPLETE & TESTED ✅

## Features Implemented

### 1. Add New Candidate Modal
**Status: COMPLETE & TESTED ✅**

**UI Components:**
- Green "➕ Add New Candidate" button (left side of toolbar)
- Blue "💾 Save All Changes" button (right side of toolbar)
- Modal form with validation

**Form Fields:**
- Employee Name (required)
- Position (required, text input)
- Location (required, dropdown from database query)
- Hire Date (required)
- Hiring Manager (required)
- Email (required)
- Notes (optional)
- Rehire checkbox (reveals "Existing Employee ID" field when checked)

**Auto-populated Fields:**
- HR Rep = logged-in user's full name
- Background Check = "Pending Consent"
- Onboarding Status = "Not Started"
- employee_status = "Active"

**Database Behavior:**
- **Normal insert:** Auto-increment ID
- **Rehire insert:** Uses manually-entered Employee ID

---

### 2. Re-hire Workflow (Save All Button)
**Status: COMPLETE & TESTED ✅**

**Trigger:** Rehire checkbox checked on existing row → Click "Save All Changes"

**User Flow:**
1. Prompt appears: "This is a RE-HIRE. Please enter the existing Employee ID:"
2. If ID entered → Saves with new_id, page reloads showing updated ID
3. If cancelled → Skips row, continues to next changed row

**Database Implementation:**
```sql
-- With ID change (rehire)
UPDATE onboarding_tracker 
SET id = ?, background_check = ?, onboard_status = ?, hr_rep = ?, notes = ?, rehire = ?, editor = ?, updated = NOW()
WHERE id = ?

-- Without ID change (normal)
UPDATE onboarding_tracker 
SET background_check = ?, onboard_status = ?, hr_rep = ?, notes = ?, rehire = ?, editor = ?, updated = NOW()
WHERE id = ?
```

**Success Messages:**
- Rehire: "Record updated successfully. ID changed from {old} to {new} (Rehire)."
- Normal: "Record ID {id} updated successfully."

---

### 3. Save All Changes Button
**Status: COMPLETE & TESTED ✅**

**Features:**
- Shows count of changed rows in real-time
- Disabled when no changes (opacity 0.5)
- Sequential save with comprehensive feedback
- Handles rehire prompts inline

**Visual Feedback:**
- **Yellow highlight:** Field changed
- **Green flash:** Save successful
- **Red flash:** Save failed
- **Status text:** "Saving...", "✓ Saved N row(s)", "✓ Saved N row(s) (M error(s))"

**Change Tracking:**
- Monitors all `.inputs_filter` fields
- Tracks `input[name="notes"]` and `input[name="rehire"]`
- Maintains Set of changed rows (survives table sorting)
- Clears tracking after successful save

---

### 4. Remove Button (Soft Delete)
**Status: COMPLETE & TESTED ✅**

**UI:**
- X button in last column of each row
- Only visible with Edit permissions

**User Flow:**
1. Click X button
2. Confirmation: "Are you sure you want to remove {name} from the onboarding tracker?"
3. If confirmed → Sets `employee_status = 'Inactive'`
4. Fade-out animation (0.5s)
5. Row removed from display

**Database:**
- **Action:** `UPDATE onboarding_tracker SET employee_status = 'Inactive' WHERE id = ?`
- **Rationale:** Soft delete preserves audit trail and allows data recovery

**Error Handling:**
- Red flash on failure
- Alert with error message
- Row remains visible

---

## Technical Stack

**Frontend:**
- Vanilla JavaScript (ES6+)
- jQuery 3.7.1 (legacy dependency)
- CSS Grid/Flexbox for layout
- Event delegation for dynamic rows

**Backend:**
- PHP 8.x with MySQLi
- Session-based authentication
- SendGrid for email notifications
- Environment-specific URL handling

**Database:**
- Table: `onboarding_tracker`
- Key fields: id (auto-increment unless rehire), employee_status, rehire flag
- Related tables: `locationInfo`, `employee_adp`

## Deployment Paths

**Production:**

- File path: TBD (separate environment)

## Key Decisions & Rationale

### 1. Manual ID Entry for Rehires
**Decision:** Prompt user to manually enter existing Employee ID

**Rejected Alternative:** ADP lookup by name
- **Reason:** Duplicate names cause ambiguity
- **Reason:** Email addresses in ADP often don't match current email
- **HR Team Preference:** Manual entry is more reliable

### 2. Soft Delete vs Hard Delete
**Decision:** Set `employee_status = 'Inactive'` instead of DELETE

**Rationale:**
- Preserves audit trail
- Allows data recovery
- Maintains referential integrity
- Matches existing system behavior

### 3. Save All vs Per-Row Save
**Decision:** Both methods supported

**Save All Behavior:**
- Prompts for rehire ID inline
- Sequential processing
- Comprehensive status reporting

**Per-Row Save:**
- No rehire ID prompting (by design)
- Immediate feedback per row
- Better for single-field edits

### 4. No Auto-Increment Corruption Risk
**Finding:** Manually-entered rehire IDs are always LOWER than current auto-increment

**Safety Net:** If high ID fat-fingered, run:
```sql
ALTER TABLE onboarding_tracker AUTO_INCREMENT = {correct_value}
```

---

## Testing Notes

**Session Debug Issues (All Resolved):**
1. User tested on production tab instead of local (3x)
2. User verified wrong rows after rehire update
3. Hard refresh required after code changes

**Final Test Results:**
- ✅ Add new candidate (normal)
- ✅ Add new candidate (rehire with manual ID)
- ✅ Edit existing row and save
- ✅ Check rehire on existing row, Save All, enter ID
- ✅ Remove candidate (soft delete)
- ✅ Save All with multiple changed rows
- ✅ Change tracking survives table sorting
- ✅ Permissions enforcement (Edit vs ReadOnly)
