#1 Example of using a function in the loop:

$pages = get_comment_pages_count();
0

#2 Example of using custom parameters

The example above uses all default values, which are taken from the settings. And this example shows how its parameters work:

// pages of comments if 25 comments per page.
$pages = get_comment_pages_count( null, 25 );

// comment pages if you do not divide comments into tree-like type (thread comments).
$pages = get_comment_pages_count( null, null, false ); 

// pages of comments, if 10 per page and they are tree-like (thread comments).
$pages = get_comment_pages_count( null, 10, true );
0

#3 Using a function outside the comment loop

If the function is used outside the comment loop, you need to specify the $comments parameter, which contains an array of comments to be counted. Such an array can be obtained by necessary arguments, using class: WP_Comment_Query{}.

Get comments on the parameters you want and find out how many pages they break down into:

$args = array(
   // query args here
);

$comments_query = new WP_Comment_Query;
$comments = $comments_query->query( $args );

$pages = get_comment_pages_count( $comments );

Notes

  • Global. WP_Query. $wp_query WordPress Query object.
