How to replace "Read more" with a widget in WordPress?

Question

Angular

Greetings.
It is very necessary to replace "Read more" with a universal version, not only "Read more", but also in other languages.
I found on the Internet how to do it with the Russian version:

function new_more_text( $more_link, $more_link_text ) {
  $new = "продолжить чтение..."; // вписываем своё
  return str_replace( $more_link_text, $new, $more_link );
}
add_filter( 'the_content_more_link', 'new_more_text', 10, 2 );

I decided to do it with the help of widgets in different languages.
But here's how you can instead of "continue reading ..." insert a widget like:
<?php dynamic_sidebar( 'readmore' ); ?>
Please tell me.

Answer 1

pass the user's serial number to the controller (in the URL, for example). In the controller you intercept the number, by it you get the user and the list of his tasks. And you work only with a specific user.
To edit a task, make a new controller, and in the same way, you need to transfer the task or its number there.
