🚀 Quick Start

Basic Usage

<?php
require_once 'vendor/autoload.php';

use KalimeroMK\PostalTracking\Services\PostalTrackingService;

$service = new PostalTrackingService();
$result = $service->trackShipment('CQ117742716DE');

if ($result['success']) {
    echo "Tracking successful!\n";
    echo "Total events: " . count($result['data']) . "\n";

    foreach ($result['data'] as $event) {
        echo "- {$event['Забелешка']} on {$event['Датум']}\n";
    }
} else {
    echo "Error: " . $result['error'] . "\n";
}
?>

With Configuration

<?php
use KalimeroMK\PostalTracking\Services\PostalTrackingService;

$service = new PostalTrackingService(
    timeout: 30,           // API timeout in seconds
    retryAttempts: 3,      // Number of retry attempts
    transformData: true    // Transform API response data
);

$result = $service->trackShipment('CQ117742716DE');
?>

🔧 Framework Integration

Laravel Setup

The package auto-registers its service provider and facade. No additional configuration required!

Basic Usage

use KalimeroMK\PostalTracking\Facades\PostalTracking;

// Track a shipment
$result = PostalTracking::trackShipment('CQ117742716DE');

// With options
$result = PostalTracking::trackShipment('CQ117742716DE', [
    'timeout' => 30,
    'retry_attempts' => 3,
    'transform' => true
]);

Controller Example

<?php
namespace App\Http\Controllers;

use Illuminate\Http\Request;
use KalimeroMK\PostalTracking\Facades\PostalTracking;

class TrackingController extends Controller
{
    public function track(Request $request)
    {
        try {
            $trackingCode = $request->get('tracking_code');
            $result = PostalTracking::trackShipment($trackingCode);

            return response()->json($result);
        } catch (\Exception $e) {
            return response()->json([
                'success' => false,
                'error' => $e->getMessage()
            ], 422);
        }
    }
}
?>

Publish Configuration (Optional)

php artisan vendor:publish --provider="KalimeroMK\PostalTracking\Laravel\PostalTrackingServiceProvider"

Service Provider Registration

The package automatically registers itself. If you need manual registration, add to config/app.php:

'providers' => [
    // ...
    KalimeroMK\PostalTracking\Laravel\PostalTrackingServiceProvider::class,
],

'aliases' => [
    // ...
    'PostalTracking' => KalimeroMK\PostalTracking\Laravel\Facades\PostalTracking::class,
],

Yii Framework Setup

Use the service directly in your controllers or components.

Basic Usage

use KalimeroMK\PostalTracking\Services\PostalTrackingService;

// In your controller
$service = new PostalTrackingService();
$trackingData = $service->trackShipment('CQ117742716DE');

// Return as JSON
Yii::$app->response->format = Response::FORMAT_JSON;
return $trackingData;

Controller Example

<?php
namespace app\controllers;

use yii\web\Controller;
use yii\web\Response;
use KalimeroMK\PostalTracking\Services\PostalTrackingService;

class TrackingController extends Controller
{
    public function actionTrack()
    {
        Yii::$app->response->format = Response::FORMAT_JSON;

        try {
            $trackingCode = Yii::$app->request->get('tracking_code');
            $service = new PostalTrackingService();
            $result = $service->trackShipment($trackingCode);

            return $result;
        } catch (\Exception $e) {
            Yii::$app->response->statusCode = 422;
            return [
                'success' => false,
                'error' => $e->getMessage()
            ];
        }
    }
}
?>

Component Registration

Add to your config/web.php or config/console.php:

'components' => [
    'postalTracking' => [
        'class' => KalimeroMK\PostalTracking\Services\PostalTrackingService::class,
        'timeout' => 30,
        'retryAttempts' => 3,
        'transformData' => true,
    ],
],

Native PHP Setup

No framework required! Perfect for standalone applications, microservices, or CLI tools.

Simple Tracker Class

<?php
require_once 'vendor/autoload.php';

use KalimeroMK\PostalTracking\Services\PostalTrackingService;

class SimplePostalTracker
{
    private PostalTrackingService $service;

    public function __construct()
    {
        $this->service = new PostalTrackingService();
    }

    public function track(string $code): array
    {
        try {
            return $this->service->trackShipment($code);
        } catch (\Exception $e) {
            return [
                'success' => false,
                'error' => $e->getMessage(),
                'code' => $code
            ];
        }
    }

    public function isValidCode(string $code): bool
    {
        return preg_match('/^[A-Z]{2}\d{9}[A-Z]{2}$/', strtoupper($code)) === 1;
    }

    public function isDelivered(string $code): bool
    {
        $result = $this->track($code);

        if ($result['success'] && !empty($result['data'])) {
            $lastEvent = end($result['data']);
            return strpos($lastEvent['Забелешка'], 'Испорачана') !== false;
        }

        return false;
    }
}

// Usage
$tracker = new SimplePostalTracker();

if ($tracker->isValidCode('CQ117742716DE')) {
    $result = $tracker->track('CQ117742716DE');

    if ($result['success']) {
        echo "Tracking successful!\n";
        echo "Total events: " . count($result['data']) . "\n";
        echo "Is delivered: " . ($tracker->isDelivered('CQ117742716DE') ? 'Yes' : 'No') . "\n";

        // Show all events
        foreach ($result['data'] as $event) {
            echo "- {$event['Забелешка']} on {$event['Датум']}\n";
        }
    }
}
?>

Web Application

<?php
require_once 'vendor/autoload.php';

use KalimeroMK\PostalTracking\Services\PostalTrackingService;

// Handle tracking request
if (isset($_GET['tracking_code'])) {
    $service = new PostalTrackingService();
    $trackingCode = $_GET['tracking_code'];

    try {
        $result = $service->trackShipment($trackingCode);

        header('Content-Type: application/json');
        echo json_encode($result, JSON_PRETTY_PRINT | JSON_UNESCAPED_UNICODE);
    } catch (\Exception $e) {
        http_response_code(422);
        echo json_encode([
            'success' => false,
            'error' => $e->getMessage()
        ]);
