Description

Joomla package that installs:

• the WebTolk/Wtmax library
• the System - WT Max system plugin

The package wraps the main webtolk/max SDK and provides a ready entry point \Webtolk\Wtmax\Wtmax::getInstance(). The bot token and service settings are stored in the system plugin.

Main SDK repository: https://github.com/WebTolk/Max-platform-PHP-SDK

Package contents

• Joomla library Webtolk/Wtmax
• system plugin for storing the token
• API connection status field
• separate file logging option

How it works

After installation:

1. enable the System - WT Max plugin
2. enter the MAX bot token
3. enable separate file logging if needed
4. in Joomla code, get the ready SDK via Wtmax::getInstance()

Internally, the library creates:

• Joomla\Http\HttpFactory
• Laminas\Diactoros\RequestFactory
• Laminas\Diactoros\StreamFactory
• a PSR-3 logger from Joomla core

Quick start

Get a ready SDK instance

<?php

declare(strict_types=1);

use Webtolk\Wtmax\Wtmax;

defined('_JEXEC') or die;

$max = Wtmax::getInstance();

$bot = $max->bots()->me();

echo $bot->getId();
echo $bot->getUsername();

Send a message to a chat

The example is based on the upstream messages()->sendToChat() flow.

<?php

declare(strict_types=1);

use Webtolk\Max\Payload\NewMessageBody;
use Webtolk\Wtmax\Wtmax;

defined('_JEXEC') or die;

$chatId = 123456;

$message = Wtmax::getInstance()->messages()->sendToChat(
	$chatId,
	NewMessageBody::text('Hello from Joomla WT Max library')
);

echo $message->getBody()?->getText() ?? '';

Send an image

The example is based on the upstream upload flow: uploads()->upload() + toAttachment() + messages()->sendToChat().

<?php

declare(strict_types=1);

use Webtolk\Max\Payload\NewMessageBody;
use Webtolk\Max\Payload\UploadType;
use Webtolk\Wtmax\Wtmax;
use RuntimeException;

defined('_JEXEC') or die;

$chatId = 123456;
$imagePath = JPATH_ROOT . '/images/sample.jpg';
$binaryImage = file_get_contents($imagePath);

if ($binaryImage === false)
{
	throw new RuntimeException('Image file was not read: ' . $imagePath);
}

$max = Wtmax::getInstance();

$imageAttachment = $max->uploads()
	->upload(UploadType::IMAGE, $binaryImage, 'image/jpeg')
	->toAttachment();

$message = $max->messages()->sendToChat(
	$chatId,
	NewMessageBody::text('Sending an image from Joomla')
		->withAttachments([$imageAttachment])
);

echo $message->getBody()?->getMessageId() ?? '';

Handle a callback and answer it

The example is based on the upstream messages()->answerCallback() flow.

<?php

declare(strict_types=1);

use Webtolk\Max\Payload\CallbackAnswerPayload;
use Webtolk\Wtmax\Wtmax;

defined('_JEXEC') or die;

$payload = file_get_contents('php://input');

if ($payload !== false && $payload !== '')
{
	$update = json_decode($payload, true, 512, JSON_THROW_ON_ERROR);
	$callbackId = $update['callback']['callback_id'] ?? null;

	if ($callbackId !== null)
	{
		Wtmax::getInstance()->messages()->answerCallback(
			(string) $callbackId,
			(new CallbackAnswerPayload())->withNotification('Button processed')
		);
	}
}

If you need a manual Max instance

Wtmax::getInstance() is convenient for typical Joomla usage, but you can also assemble the SDK manually if needed.

<?php

declare(strict_types=1);

require_once JPATH_LIBRARIES . '/Webtolk/Wtmax/src/libraries/vendor/autoload.php';

use Joomla\Http\HttpFactory;
use Laminas\Diactoros\RequestFactory;
use Laminas\Diactoros\StreamFactory;
use Webtolk\Max\Config\MaxConfig;
use Webtolk\Max\Max;
use Psr\Log\NullLogger;

defined('_JEXEC') or die;

$token = 'YOUR_BOT_TOKEN';

$max = new Max(
	new MaxConfig($token),
	new NullLogger()
);

$max->setTransport(
	(new HttpFactory())->getHttp([], ['curl', 'stream']),
	new RequestFactory(),
	new StreamFactory(),
);

Where the token is stored

The token is stored in the parameters of the System - WT Max system plugin.

Main parameters:

• MAX bot token
• Log to a separate file
• Custom log file

Logging

If logging is enabled, the library writes to a separate file:

/logs/wtmax.max-api.log
