In this blog post, we will explore how to create an interactive Telegram inline keyboard for your PHP bot. Inline keyboards are an essential feature that enhances user interaction, allowing users to easily navigate through options, send requests, and receive quick responses. Whether you're building a bot for fun or developing a robust application, understanding how to implement inline keyboards effectively will significantly enhance your bot's functionality. Let's dive into the details and see how you can integrate this feature into your Telegram bot!

Creating an inline keyboard for a Telegram bot using PHP involves several steps, including setting up your bot, configuring the webhook, and handling user interactions. Below, you will find an outlined process to set up your inline keyboard and manage callbacks effectively.

1. Set Up Your Telegram Bot

Before creating an inline keyboard, you need to create a bot and acquire the bot token. Follow these steps:

  • Open Telegram and search for the BotFather.
  • Send the command /newbot to create a new bot.
  • Follow the instructions to name your bot and get a unique username.
  • After creating the bot, you will receive a token. Save this token for later use.

2. Configure Webhook

To receive updates from Telegram, you need to set up a webhook that points to your PHP script. Use the following command:

https://api.telegram.org/bot

Replace

3. Creating an Inline Keyboard

To create an inline keyboard, you need to use the Telegram API. Here is a code snippet for generating an inline keyboard:


$keyboard = [
    'inline_keyboard' => [
        [['text' => 'Option 1', 'callback_data' => 'option1']],
        [['text' => 'Option 2', 'callback_data' => 'option2']],
    ]
];

Once you have your keyboard defined, use it in a sendMessage method:


$data = [
    'chat_id' => $chatId, 
    'text' => 'Choose an option:', 
    'reply_markup' => json_encode($keyboard)
];
file_get_contents("https://api.telegram.org/bot

4. Handling Callbacks

When a user presses a button on the inline keyboard, a callback query is sent to your webhook. Here’s how to handle it:


$update = json_decode(file_get_contents('php://input'));
if (isset($update->callback_query)) {
    $callbackData = $update->callback_query->data;
    $chatId = $update->callback_query->message->chat->id;

    // Process the callback data
    switch ($callbackData) {
        case 'option1':
            // Handle option 1
            break;
        case 'option2':
            // Handle option 2
            break;
    }
}

Make sure to respond back to the user to acknowledge their selection using the answerCallbackQuery method if needed.

5. Testing Your Bot

Once everything is set up:

  • Open your Telegram bot and send a message to initiate conversation.
  • Test the inline keyboard by clicking the buttons and confirm that the callbacks are processed correctly.

By following these steps, you can successfully create an inline keyboard for your Telegram bot using PHP, enhancing user interaction and engagement. Happy coding!
