Creating interactive buttons for a Telethon-based Telegram bot

I’m working on a Telegram bot using Telethon and I’ve set up some buttons. Here’s what I’ve got so far:

@bot.on(events.NewMessage(pattern="menu"))
async def show_options(event):
    menu_buttons = [
        [  
            Button.inline("Option A", b"A"), 
            Button.inline("Option B", b"B")
        ],
        [
            Button.inline("Option C", b"C"), 
            Button.inline("Option D", b"D")
        ],
        [
            Button.inline("Option E", b"E")
        ]
    ]

    await bot.send_message("chat_id",
                           "Select an option:", 
                           buttons=menu_buttons)

I’m struggling to figure out how to make the buttons actually do something when clicked. For example, I want to send a certain number of photos based on user input. Any ideas on how to implement this? I’m pretty new to Telethon and could use some guidance. Thanks!

As someone who’s worked extensively with Telethon bots, I can share some insights on handling button interactions. The key is to use callback queries.

First, set up a callback handler using @bot.on(events.CallbackQuery()). Inside this handler, you’ll want to check the event.data to determine which button was clicked.

For sending photos based on user input, you could do something like this:

@bot.on(events.CallbackQuery())
async def handle_button(event):
    if event.data == b'A':
        num_photos = 2
        for _ in range(num_photos):
            await bot.send_file(event.chat_id, 'path/to/photo.jpg')
    # Handle other buttons similarly

Remember to call event.answer() to acknowledge the callback query. This prevents the button from showing a loading state indefinitely.

Hope this helps you get started with interactive buttons in your Telethon bot!

To make your buttons interactive, you’ll need to set up callback handlers for each button. Here’s a basic approach:

  1. Define callback handlers for each button.
  2. Use @bot.on(events.CallbackQuery()) to create these handlers.
  3. Check the data attribute of the callback to determine which button was pressed.
  4. Implement the desired action for each button.

Here’s a simple example:

@bot.on(events.CallbackQuery())
async def callback_handler(event):
    if event.data == b'A':
        await event.answer('You selected Option A')
        # Add your logic for Option A here
    elif event.data == b'B':
        await event.answer('You selected Option B')
        # Add your logic for Option B here
    # ... and so on for other options

    # For sending photos based on user input:
    if event.data == b'C':
        num_photos = 3  # Example: send 3 photos
        for _ in range(num_photos):
            await bot.send_file(event.chat_id, 'path/to/photo.jpg')

This structure allows you to define specific actions for each button click.

hey, i’ve dun this b4. u need to use callback queries for the buttons. heres a quick example:

@bot.on(events.CallbackQuery())
async def handle_click(event):
if event.data == b’A’:
await event.answer(‘u picked A!’)
await bot.send_file(event.chat_id, ‘pic1.jpg’)
# do similar 4 other buttons

hope this helps u out!
