Entering command for telegram bot?

Question

PHP

Now I use this option:
/add [name]
and, accordingly, a regular expression for this:

preg_match('/\/add\s(.+)/i, $msg, $msg)
$msg = $msg[1];
...

I want to make it so that after entering / add, the bot prompts you to enter a name. If, for example, within 30 seconds, the user did not enter anything, then the command was canceled. How it is better to implement it?

Answer 1

We save an entry in the cache that we are waiting for a message from such and such a user and write a handler (callback) there. With each request, we check if there is something in the cache, if there is, then we call the callback, otherwise we call the standard command handler.
