    The get_next_comments_link() function in WordPress is designed to retrieve the link to the next page of comments on a post. This function is particularly useful for navigation in comment sections that span multiple pages. Here's a detailed explanation of its usage:

    Function Signature

    get_next_comments_link( string $label = "", int $max_page = 0 ): string|void
    

    Parameters

    1. $label (string, optional):

      • Description: This parameter specifies the text that will be displayed for the link.
      • Default Value: An empty string (''). If not provided, WordPress will use a default label.
    2. $max_page (int, optional):

      • Description: This parameter defines the maximum number of comment pages. It is used to determine if there is a 'next' page to navigate to.
      • Default Value: 0. When set to 0, WordPress calculates the maximum number of pages based on the total number of comments and the comments per page setting.

    Return Value

    • string|void: The function returns an HTML-formatted link to the next page of comments. If there is no next page (i.e., the user is on the last page of comments or there are no comments), the function returns void.

    Usage Example

    Here's how you might use get_next_comments_link() in a WordPress theme:

    <?php
    // Define a label for the link
    $next_comments_label = 'Next Comments Page';
    
    // Use the function to get the link to the next page of comments
    $next_comments_link = get_next_comments_link($next_comments_label);
    
    // Check if the link is available and display it
    if ($next_comments_link) {
        echo '<div class="next-comments-link">';
        echo $next_comments_link;
        echo '</div>';
    }
    ?>
    

    In this example, the function is used to get the link for the next page of comments with a custom label "Next Comments Page". If the link is available, it is wrapped in a div element for styling and displayed on the page.

    This function is useful for creating a more navigable and user-friendly comment section in WordPress sites, especially when dealing with posts that attract a large number of comments.
