* Centralized Trip Pricing Service |
| 9 |
* |
| 10 |
* SINGLE SOURCE OF TRUTH for all trip pricing display logic. |
| 11 |
* Eliminates redundant pricing resolution across controllers, templates, and shortcodes. |
| 12 |
* |
| 13 |
* Used by: |
| 14 |
* - SingleTripController (sidebar pricing, effective_price_min) |
| 15 |
* - TripController (availability card pricing) |
| 16 |
* - BookingSessionController (session pricing) |
| 17 |
* - content-sidebar.php (sidebar display) |
| 18 |
* - Shortcodes (Destination, Activity, DiscountAndDeals) |
| 19 |
* - Listing pages |
| 20 |
* |
| 21 |
* PRICING PRIORITY (Regular): |
| 22 |
* discounted_price → sale_price → original_price |
| 23 |
* |
| 24 |
* PRICING PRIORITY (Traveler-Based): |
| 25 |
* per-category discounted_price → sale_price → original_price |
| 26 |
* Display shows minimum effective price across all categories |
| 27 |
* |
| 28 |
* FILTER HOOKS (for Yatra Pro): |
| 29 |
* - yatra_resolve_display_pricing → Modify complete display pricing result |
| 30 |
* - yatra_resolve_card_pricing → Modify per-card pricing on availability section |
| 31 |
* - yatra_resolve_effective_price → Modify single effective price (used in listings) |
| 32 |
* - yatra_resolve_pricing_type → Override pricing type detection |
| 33 |
* - yatra_resolve_price_types → Modify normalized price_types array |
