📞 Common Questions

Q1: Where is the new API?

A: /workpro/public/api/get-boq-statistics.php

Q2: What changes were made to work-entry.php?

A:

• Line 548: Label changed
• Lines 939-951: Function call added
• Lines 1309-1365: New function added (See: EXACT_CHANGES.md)

Q3: How do statistics get updated?

A: When user selects an item, loadBOQStatistics() is called, which makes AJAX request to API

Q4: What if API fails?

A: Statistics reset to 0, error logged to console, user sees fallback display

Q5: Does this work for all user roles?

A: Yes, with RBAC:

• ADMIN: See all items
• Non-ADMIN: See only own DC items

Q6: Is it secure?

A: Yes, multiple layers:

• Authentication check
• RBAC enforcement
• SQL injection prevention
• Input validation
• Error handling

Q7: What's the performance impact?

A: ~30-50ms per item selection (acceptable)

Q8: How do I test RBAC?

A: Login as different users and verify access restrictions (See: Testing checklist)

Q9: How do I rollback if needed?

A: See: EXACT_CHANGES.md → Rollback Instructions

Q10: Where do I find error logs?

A: Server logs: /logs/ directory; Browser console: F12

📊 Statistics Display Logic

When user selects an item:

API Query 1: SELECT totalQty, doneQty FROM boq WHERE boqId=?
    └─ Returns: Item's quantities

API Query 2: SELECT COUNT(*) FROM work_entries WHERE boqId=? AND status='PENDING'
    └─ Returns: Count of pending work

Display Values:
- BOQ: totalQty (from boq table)
- Completed: doneQty (from boq table)
- Awaiting: pending count (from work_entries)
- Remaining: totalQty - doneQty (math)

🔐 Security Layers

1. Authentication
   └─ User must be logged in

2. RBAC
   └─ User's dcId must match item's dcId (unless ADMIN)

3. SQL Injection Prevention
   └─ All queries use parameterized statements

4. Input Validation
   └─ Optional filters validated against item data

5. Error Handling
   └─ Exceptions caught, errors logged, safe messages returned
