#### Features:
- Validates required fields:

### 6. API: api/branch/read.php
**Status:** ✅ Verified
**Purpose:** Populate branch filter dropdown

## Key Issues Fixed

### Issue 1: Search Event Binding Error
**Problem:** `.on()` method called incorrectly without event type
```javascript
// Before (WRONG)
$('#btnSearch, #searchInput').on(function(e) { ... });

// After (CORRECT)
function performSearch() { ... }
$('#btnSearch').click(performSearch);
$('#searchInput').keypress(function(e) { if (e.which == 13) performSearch(); });
```

### Issue 2: Toast Function References
**Problem:** `showtoastt()` function doesn't exist
**Solution:** Replaced all `showtoastt()` calls with `alert()` for basic notifications

### Issue 3: Missing consignor_name Field
**Note:** API returns `consignor_name` from tbl_bookings table
**Status:** Verify in database that this field exists

## Known Limitations

1. **Consignor/Origin/Destination Fields:** Current table shows "- " for these fields
   - Need to add fields to tbl_bookings or join with additional tables
   - Expected columns: origin_state, origin_city, origin_pincode, destination_state, destination_city, destination_pincode

2. **No.Of Boxes & Weight:** Shows hardcoded values (1 and 0)
   - Need to add columns to tbl_bookings: no_of_boxes, weight

3. **Toast Notifications:** Currently using browser alert()
   - Consider implementing a proper toast library (Toastr.js, Bootstrap Toast)

4. **Date/Time Format:** Status date must be selected from date picker
   - Time is auto-filled from current time
   - Consider adding time picker for precise control

## Browser Requirements
- Modern browser with ES6 support
- jQuery 1.8+
- Bootstrap 5 (for styling)

## API Endpoints Used
```
GET  /api/shipment/read.php          - Load shipments for table

```

## Next Steps (Optional Enhancements)

1. **Add Missing Fields:** Implement origin/destination/consignor fields
2. **Improve Notifications:** Replace alert() with proper toast library
3. **Add Validation:** Client-side validation for all inputs
4. **Pagination:** Add pagination to shipments table
5. **Export:** Add ability to export tracking history
6. **Bulk Updates:** Allow updating multiple shipments at once
