Set noindex page-comment from Pages 2, 3 and More?

I use All in one seo pack plugin.

I see that Google indexed page comments (that are a pages generated from paginated comments).

The example url are the followings:

1. URL canonical - mydomain.com/url-canonical
2. URL comment page - mydomain.com/url-canonical/comment-page-3

The problem is that 'URL comment page' has itself as canonical, and not the main page.

I'd like to set as noindex all comment-page for all postes. Is it possible?

I see that AIO SEO has aioseo_filter_robots_meta, but I do not understand how to filter it for comment-page.

I have the following code, but it is only for singular:

add_filter( 'aioseo_robots_meta', 'aioseo_filter_robots_meta' ); function aioseo_filter_robots_meta( $attributes ) { if ( is_singular() ) { $attributes['noindex'] = 'noindex'; $attributes['nofollow'] = 'nofollow'; } return $attributes; } 

There is a way to add meta tag robots noindex only for all comment-page?

Solved by following code:

 add_filter( 'aioseo_robots_meta', 'aioseo_filter_robots_meta' ); function aioseo_filter_robots_meta( $attributes ) { global $cpage; if (!empty($cpage) && $cpage > 0) { $attributes['noindex'] = 'noindex'; } return $attributes; }
