Type pokerp status to see the current status of the session (who has voted).

Type pokerp end in a public channel and the bot will output each vote.

Load your own commands

You can load your own commands by implementing the \PhpSlackBot\Command\BaseCommand.

Then call PhpSlackBot\Bot::loadCommand method for each command you have to load.

"Catch All" command

If you need to execute a command when an event occurs, you can set up a "catch all" command.

This special command will be triggered on all events and all other commands will be ignored.

require 'vendor/autoload.php';
use PhpSlackBot\Bot;

// This special command executes on all events
class SuperCommand extends \PhpSlackBot\Command\BaseCommand {

    protected function configure() {
        // We don't have to configure a command name in this case
    }

    protected function execute($data, $context) {
        if ($data['type'] == 'message') {
            $channel = $this->getChannelNameFromChannelId($data['channel']);
            $username = $this->getUserNameFromUserId($data['user']);
            echo $username.' from '.($channel ? $channel : 'DIRECT MESSAGE').' : '.$data['text'].PHP_EOL;
        }
    }

}

$bot = new Bot();
$bot->setToken('TOKEN'); // Get your token here https://my.slack.com/services/new/bot
$bot->loadCatchAllCommand(new SuperCommand());
$bot->run();

Incoming webhooks

The bot can also listen for incoming webhooks.

Commands are triggered from users messages inside Slack and webhooks are triggered from web post requests.

Custom webhooks can be loaded using the PhpSlackBot\Bot::loadWebhook method.

This is useful if you need to control the bot from an external service. For example, with IFTTT https://ifttt.com/maker

To enable webhooks, use the enableWebserver method before the run method.

You can also set a secret token to prevent unauthorized requests.

$bot->enableWebserver(8080, 'secret'); // This will listen on port 8080
$bot->run();

Then, use the parameter "name" to trigger the corresponding webhook :

curl -X POST --data-urlencode 'auth=secret' --data-urlencode 'name=output' --data-urlencode 'payload={"type" : "message", "text": "This is a message", "channel": "#general"}' http://localhost:8080
