Fixes #17 Implements a backward-compatible fix for the editcarinfo.php endpoint. The script now accepts either ID or �ssetID as the identifier for updates, prioritizing ID. This resolves the contract mismatch where the Flutter client was sending �ssetID while the backend expected the primary key ID. The endpoint now also uses prepared statements and returns a standardized JSON response.
Fixes #28 Refactors getallclients.php and getallpolicies.php to use the standard API response envelope: { success, message, data: { items: [...] } }. Also updates getallpolicies.php to use the JWT-based auth check instead of the legacy phpPassword.
Reviewer's GuideStandardizes backend API response envelopes for car info, policies, and clients endpoints, introduces JWT-based protection for policies/clients, improves editcarinfo update logic, and adds community standards/docs plus CI Java version bump.

Preserve top-level clients list for existing app code
This endpoint now nests the list under data.items, but the Flutter clients still read a top‑level clients array (e.g., lib/client/pages/clientlist.dart expects jsonData['clients'] or a direct list). Because data is now an object instead of a list, those callers fall into the error path and show “Müşteri verisi bulunamadı”, even though the API succeeded. Consider keeping the legacy clients key or updating all client call sites to read data.items.
Useful? React with 👍 / 👎.

Keep policies list key or update all consumers
The response now moves the policies list into data.items, but multiple Flutter screens still parse policies at the top level (e.g., lib/police/pages/all_policies.dart uses policiesJson['policies']). With the new shape, those screens will render zero policies even on success. Either preserve policies for backward compatibility or update all policy consumers to read data.items.

JWT-only auth will 401 existing policy fetches
Switching this endpoint to auth_check.php makes the Authorization header mandatory, and auth_check.php immediately returns 401 when it’s missing. The Flutter app still calls this endpoint with only phpPassword in the body (e.g., lib/police/pages/all_policies.dart), so those calls will now fail. If the mobile app isn’t updated to send JWTs everywhere, you’ll need a temporary compatibility path.

Adds composer.json to define PHP dependencies (phpunit, phinx). Updates phpunit.xml.dist and adds a bootstrap file to correctly load test files and functions. This resolves the 'composer.json not found' error in the Backend CI job.

Hey - I've found 4 issues, and left some high level feedback:
- In the new standardized response envelopes, consider avoiding exposing raw database or internal exception messages (e.g.,
mysqli_errortext) directly inmessageto prevent leaking internal details to API consumers; instead log the detailed error and return a generic user-facing message. - The response
datapayload shape differs between endpoints (e.g.,getallpoliciesreturns{"items": [...], "count": n}whilegetallclientsreturns only{"items": [...]}); aligning these structures will make client-side handling simpler and more predictable.

## Overall Comments
- In the new standardized response envelopes, consider avoiding exposing raw database or internal exception messages (e.g., `mysqli_error` text) directly in `message` to prevent leaking internal details to API consumers; instead log the detailed error and return a generic user-facing message.
- The response `data` payload shape differs between endpoints (e.g., `getallpolicies` returns `{"items": [...], "count": n}` while `getallclients` returns only `{"items": [...]}`); aligning these structures will make client-side handling simpler and more predictable.

**suggestion (bug_risk):** Returning a 500 for missing update fields makes a client-side error look like a server error.
Because no HTTP status is set before throwing, the catch block will see `http_response_code() === 200` and turn this into a 500, misclassifying a client error as a server error. Consider explicitly setting an appropriate 4xx status (e.g., 400 or 422) before throwing so it’s consistent with other validation failures like the missing ID/assetID case.

Breaking change detected: The response structure has been changed from {"clients": [...], "success": true} to {"data": {"items": [...]}, "success": true, "message": "..."}. Multiple frontend consumers (lib/client/pages/clientlist.dart:63, lib/police/pages/newpolicy.dart:140, lib/police/pages/editpolicy.dart:138, lib/police/pages/receivables_page.dart:135) expect the clients key directly at the root level. While clientlist.dart has a fallback that checks both clients and data keys (line 63), other consumers do not have this fallback and will break. Consider either: 1) Keeping backward compatibility by including both formats temporarily, or 2) Coordinating this backend change with corresponding frontend updates in the same PR.

The date format validation for the seyruseferdate field has been removed in this refactoring. The original code validated that dates matched the YYYY-MM-DD format using a regex pattern. This validation should be restored to ensure data integrity. Add validation similar to: if ($value !== '' && !preg_match('/^\d{4}-\d{2}-\d{2}$/', $value)) throw new Exception('seyruseferdate must be in YYYY-MM-DD format'); before line 55.

The response envelope structure is inconsistent across the codebase. This endpoint uses {"data": {"items": [...]}}, while similar endpoints like getcarinfo.php (backend/carinfos/getcarinfo.php:7) use {"carinfo": ...} as the data key. For true API standardization, consider documenting the standard envelope format and applying it consistently across all endpoints. The standard structure should be: {"success": bool, "message": string, "data": object|array|null} where the data key always contains the actual payload, regardless of whether it's a single item, list, or metadata object.

When no fields are provided for update, the error message "No fields to update were provided." will be shown, but the HTTP status code remains 200 (OK). Consider setting an appropriate HTTP status code (e.g., 400 Bad Request) before throwing the exception, similar to how it's done for missing identifiers on lines 32-33.

The comment indicates JWT authentication will be added in a later phase (P2), but this endpoint is already being refactored in this PR focused on security improvements (changing authentication from phpPassword to JWT for getallpolicies.php). Consider prioritizing JWT authentication for this endpoint as well, since it handles sensitive car information updates. If that's not feasible in this PR, at least ensure the phpPassword check includes proper timing-safe comparison to prevent timing attacks.
| // For now, we retain the phpPassword check for basic security. | |

There was a problem hiding this comment.
The error message strings have been changed from Turkish to English (e.g., "Araç güncellendi" → "Car info updated successfully."), but other parts of the codebase still use Turkish error messages (e.g., backend/carinfos/getcarinfo.php uses Turkish: "Invalid authentication."). This creates inconsistency in the user experience. Consider either: 1) Maintaining Turkish messages to match the rest of the codebase, or 2) Implementing proper internationalization (i18n) support if multilingual messages are desired.

This endpoint exposes raw database error messages to API clients by throwing new Exception(mysqli_error($connNow)) and then returning "An error occurred: " . $e->getMessage() in the JSON response. An attacker who can trigger a database error (e.g., via operational failures or future query changes) can harvest internal details about your schema or infrastructure, which materially aids further exploitation. Instead, log detailed database errors on the server and return only a generic, client-safe error message in the HTTP response.

This endpoint leaks internal database error details to callers by constructing exceptions with ... $connNow->error / $stmt->error and then returning $e->getMessage() directly in the JSON message field. An attacker who can trigger SQL preparation or execution failures can obtain detailed information about the database schema or environment, which can significantly aid further exploitation. Instead, capture and log the detailed exception messages server-side and return a generic, user-friendly error message in the API response.
