is_single is_singular is not working

i have a weird issue. If i use a clean install and add code like this in the functions.php of f.e. the 20-21 theme and go to the single post page in the front end that echo does not happen.

I am using the latest beta version of wordpress 5.7 and php 8.0

any idea why this is not happening?

if (is_singular( 'post' )) echo '---------------------------> this is a post';

if (is_single()) echo '---------------------------> this is a post';

if i add it without checking

echo '---------------------------> this is a post';

The text of course shows.

What is going on that this does not work in the functions.php on a single post page?

I tried any defaul wp theme and premium theme and they all have the same problem.

Hi @BackuPs,

Looks like this is a support question (in which context is_single/is_singular function can be used) rather than a bug/enhancement report. I'd suggest to ask in WordPress support forums instead:

Thanks for your comprehension

By the way, these conditional tags must be used inside the loop, and functions.php is called before the loop.

Try add_action( 'wp_body_open', function() { var_dump( is_single() ); } );.

However, please avoid to open Trac tickets for support questions ;)
