Creating a custom keyboard for a PHP-based Telegram Bot

I’m having trouble setting up a custom keyboard for my Telegram Bot using PHP. The bot sends messages fine, but the keyboard isn’t showing up. I’ve tried different approaches like:

$keyboard = [
    'keyboard' => [
        ['Option 1', 'Option 2'],
        ['Option 3', 'Option 4']
    ]
];

$message = [
    'chat_id' => $chatId,
    'text' => 'Please choose an option:',
    'reply_markup' => json_encode($keyboard)
];

$response = file_get_contents($botApiUrl . '/sendMessage?' . http_build_query($message));

But it’s not working as expected. The Telegram API docs mention ReplyKeyboardMarkup, but I’m not sure how to implement it correctly. I’ve looked for examples online, but couldn’t find any that show how to use custom keyboards.

Has anyone successfully created a custom keyboard for a Telegram Bot using PHP? What am I missing? Any help would be great!

I’ve encountered this issue before when working with Telegram bots in PHP. The problem might be related to how you’re sending the request to the Telegram API. Instead of using file_get_contents(), try using cURL. It offers more control and better error handling. Here’s an example:

$keyboard = [
    'keyboard' => [
        ['Option 1', 'Option 2'],
        ['Option 3', 'Option 4']
    ],
    'resize_keyboard' => true,
    'one_time_keyboard' => true
];

$data = [
    'chat_id' => $chatId,
    'text' => 'Please choose an option:',
    'reply_markup' => json_encode($keyboard)
];

$ch = curl_init($botApiUrl . '/sendMessage');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);

if ($response === false) {
    // Handle error
    error_log('Telegram API request failed: ' . curl_error($ch));
}

This approach should resolve the keyboard issue. If you’re still experiencing problems, check your bot token and ensure you have the necessary permissions.

hey alexlee, i had similar issues. try this:

$keyboard = [
    'keyboard' => [
        ['Option 1', 'Option 2'],
        ['Option 3', 'Option 4']
    ],
    'resize_keyboard' => true
];

$data = [
    'chat_id' => $chatId,
    'text' => 'Choose:',
    'reply_markup' => json_encode($keyboard)
];

file_get_contents($botApiUrl . '/sendMessage?' . http_build_query($data));

this worked for me. hope it helps!

I’ve worked extensively with Telegram bots in PHP, and I can share some insights that might help you resolve this issue. The problem likely stems from how you’re encoding the keyboard array.

Instead of using ‘keyboard’ as the top-level key, try wrapping it in a ‘reply_markup’ array. Here’s a modified version of your code that should work:

$keyboard = [
    'reply_markup' => [
        'keyboard' => [
            ['Option 1', 'Option 2'],
            ['Option 3', 'Option 4']
        ],
        'resize_keyboard' => true,
        'one_time_keyboard' => true
    ]
];

$message = [
    'chat_id' => $chatId,
    'text' => 'Please choose an option:',
    'reply_markup' => json_encode($keyboard['reply_markup'])
];

$response = file_get_contents($botApiUrl . '/sendMessage?' . http_build_query($message));

This structure aligns more closely with what the Telegram API expects. The ‘resize_keyboard’ and ‘one_time_keyboard’ options are optional but can enhance user experience. If this doesn’t solve your issue, double-check your API URL and make sure you’re using the correct bot token.
