Hey guy’s am having a problem with python-telegram-bot, what am doing is a bot that you start by pasting url for any file you want or Youtube videos, but am having a problem where I have two message handlers with the filter filters.TEXT, the first handler is for files like photos or documents to be downloaded, and the second one is for Youtube links to be downloaded with the pytube lib.

When having the first handler on the top of the other it works first as expected, but when the condition is not met it does not go to the next message handler, only stays in the first and nothing happens.

This is my my code:

import requests
from telegram import Update
from telegram.ext import CommandHandler, ContextTypes, Application, filters, MessageHandler
from io import BytesIO
from pytube import YouTube


class FileHandler:
    def __init__(self):
        self.text = None

    async def download_upload(self, update: Update, context: ContextTypes.DEFAULT_TYPE):
        self.text = update.message.text
        # print(f"User: {self.text}")

        if "youtu.be" not in self.text:
            file_buffer = BytesIO()

            request = requests.get(self.text)
            print(f"Status-code: {request.status_code}")
            file_size = int(request.headers.get('Content-Length'), 0)

            if request.status_code == 200:
                print("Status-download: file good to download")
                await update.message.reply_text("Please wait, if file is above 1MB it might take a bit because of some "
                                                "network issues.")
                file_buffer.write(request.content)
                file_buffer.seek(0)
                if self.photo_or_doc(self.text) == "photo":
                    await context.bot.send_photo(chat_id=update.message.chat_id, photo=file_buffer,
                                                 caption="This is your Photo"
                                                         " :)")
                else:
                    await context.bot.send_document(chat_id=update.message.chat_id, document=file_buffer,
                                                    caption="This is your Document"
                                                            " :)")
            else:
                print(f"Error {request.status_code}")


    def photo_or_doc(self, url):
        response = requests.head(url)
        file_type = response.headers.get("Content-Type", "")

I read that there are handler callbacks or something like that, but I don’t know what they do, or what they even are.

I tried with if else statements, but couldn’t get from one handler to the other if the condition is not met.
