Concepts

Main concept

The main concept is creating handlers for incoming updates from telegram.

It should implement abstract handler

Examples of handlers

There is one build in handler for telegram commands

Service provider

To define custom handlers or telegram-command-handler, it necessary to create and register own service provider and extend it from \MadmagesTelegram\Laravel\HandlerServiceProvider

<?php 
declare(strict_types=1);

namespace App\Providers;

class TelegramServiceProvider extends \MadmagesTelegram\Laravel\HandlerServiceProvider
{

    /** @var array Handlers for telegram commands */
    protected array $telegramCommands = [];

    // Other handlers
    protected array $messageHandlers = [
        // This handler is for telegram-commands,
        // i.e. it makes $this->telegramCommands working
        \MadmagesTelegram\Laravel\Handler\Command\CommandHandler::class
    ];
    protected array $editMessageHandlers = [];
    protected array $channelPostHandlers = [];
    protected array $editedChannelPostHandlers = [];
    protected array $inlineQueryHandlers = [];
    protected array $chosenInlineResultHandlers = [];
    protected array $callbackQueryHandlers = [];
    protected array $preCheckoutQueryHandlers = [];
    protected array $shippingQueryHandlers = [];
    protected array $pollAnswerHandlers = [];
    protected array $pollHandlers = [];
}

Command handler

The command handler built for handling telegram commands i.e. /start for example.

All commands should implement AbstractCommand and should be defined in \MadmagesTelegram\Laravel\HandlerServiceProvider::$telegramCommands of own service provider

<?php declare(strict_types=1);

namespace App\Module\Telegram\Command;

use MadmagesTelegram\Laravel\Handler\Command\AbstractCommand;
use MadmagesTelegram\Laravel\WebhookClient;
use MadmagesTelegram\Types\Type\Message;
use Illuminate\Http\JsonResponse;

class Start extends AbstractCommand
{

    private WebhookClient $client;

    public function __construct(WebhookClient $client)
    {
        // It possible to response, during webhook request 
        // https://core.telegram.org/bots/api#making-requests-when-getting-updates
        $this->client = $client;
    }
    
     public function getName(): string
    {
        return 'start';
    }

    public function execute(Message $message, bool $isPrivate): ?JsonResponse
    {
        return $this->client->sendMessage($message->getChat()->getId(), 'Hello there !');
    }
}

and register it

<?php 
declare(strict_types=1);

namespace App\Providers;

class TelegramServiceProvider extends \MadmagesTelegram\Laravel\HandlerServiceProvider
{
    protected array $telegramCommands = [
        \App\Module\Telegram\Command\Start::class
    ];
}

Laravel commands

madmagestelegram:registerWebhook - register webhook in telegram. It makes all handlers to work
