Function and usage of get_page_of_comment() in wordpress


Answers ( 1 )


    The get_page_of_comment() function in WordPress is designed to calculate the page number on which a specific comment appears, considering the settings for comment paging. This is particularly useful in websites with a large number of comments, where comments are divided into pages for easier navigation.

    Function Signature

    get_page_of_comment( int $comment_id, array $args = array() ): int|null


    1. $comment_id (int, required): This is the unique identifier of the comment. You need to provide the ID of the comment for which you want to find the page number.

    2. $args (array, optional): This is an array of optional arguments that can be used to modify the behavior of the function. These include:

      • type (string): This argument limits paginated comments to those matching a specific type. The accepted values are 'comment', 'trackback', 'pingback', 'pings' (which includes both trackbacks and pingbacks), or 'all'. The default value is 'all'.

      • per_page (int): This specifies the number of comments per page. This is used in calculating the pagination. By default, it uses the value set in the 'comments_per_page' option in WordPress settings.

      • max_depth (int|string): If this value is greater than 1, the comment page number will be determined for the top-level parent of the given $comment_id. This is relevant in threaded (nested) comments. The default value is the setting of 'thread_comments_depth' in WordPress.

    Return Value

    • int|null: The function returns the page number on which the comment appears. If there is an error (for example, if the comment ID does not exist), the function returns null.

    Sample Usage

    Here's an example of how you might use get_page_of_comment():

    $comment_id = 123; // Replace with the actual comment ID
    $args = array(
        'type' => 'all', 
        'per_page' => 10, 
        'max_depth' => 3
    $page_number = get_page_of_comment($comment_id, $args);
    if ($page_number !== null) {
        echo "Comment is on page " . $page_number;
    } else {
        echo "Error: Comment not found or other error occurred.";

    In this example, we're trying to find out on which page the comment with ID 123 appears. We're looking for all types of comments, limiting to 10 comments per page, and considering a max depth of 3 for nested comments. If the function is successful, it returns the page number; otherwise, it indicates an error.
