I'm trying to send a message in a channel with a bot, using Telegram API's send_photo()
method. It takes a caption parameter (type String
) but I can't format it through parse_mode='HTML'
parameter...
If I use something like this:
send_photo(chat_id, photo, caption="<b>Some text</b>", parse_mode='HTML')
it sends the message but without any kind of formatting. Does anybody know why? Thanks
First, you need to import ParseMode
from telegram
like this:
from telegram import ParseMode
Then, all you need is to specify parse_mode=ParseMode.HTML
. Here's a working example:
def jordan(bot, update):
chat_id = update.message.chat.id
with open('JordanPeterson.jpg', 'rb') as jordan_picture:
caption = "<a href='https://twitter.com/jordanbpeterson'>Jordan B. Peterson</a>"
bot.send_photo(
chat_id,
photo=jordan_picture,
caption=caption,
parse_mode=ParseMode.HTML
)
And we can see that it works:
Update: Actually, both parse_mode='html'
(as suggested by @slackmart) and parse_mode='HTML'
that you used yourself work for me!
Another Update (as per your comment): You can use multiple tags. Here's an example of one, with hyperlink
, bold
, and italic
:
Yet Another Update: Regarding your comment:
...do I have any limitations on HTML tags? I can't use something like
<img>
or<br>
to draw a line
Honestly,
That's what I did!
Now you're trying to format the caption of an image, using HTML
, meaning you're formatting a text
, so obviously, you can't use "something like <img>
." It has to be a "text formatting tag" (plus <a>
). And not even all of them! I believe you can only use these: <a>
, <b>
, <strong>
, <i>
and <em>
.
If you try to use a text-formatting tag like <del>
, it will give you this error:
Can't parse entities: unsupported start tag "del" at byte offset 148
Which is a shame! I'd love to be able to do something like this in captions of images.or something like this!
It works for me! Here's the code I'm using:
>>> from telegram import Bot
>>> tkn = '88888:199939393'; chid = '-31828'
>>> bot = Bot(tkn)
>>> with open('ye.jpeg', 'rb') as fme:
... bot.send_photo(chid, fme, caption='<b>Hallo</b>', parse_mode='html')
...
<telegram.message.Message object at 0x7f6301b44d10>
Of course, you must use your own telegram token and channel id. Also notice I'm using parse_mode='html' # lowercase
