    The get_post_reply_link() function in WordPress is used to retrieve HTML content for a link that allows users to reply to a post. This function is especially useful for theme and plugin developers who need to provide an interactive commenting feature on WordPress posts. Let's break down its usage and parameters.

    Function Signature

    get_post_reply_link( array $args = array(), int|WP_Post $post = null ): string|false|null
    

    Function Description

    • Purpose: To generate a link that, when clicked, displays a form allowing users to leave a reply or comment on a post.
    • Return Values: It returns a string containing the HTML for the reply link, false if comments are closed or not allowed, or null if the post does not exist.

    Parameters

    1. $args (array - optional): This array allows you to override default arguments. It includes:

      • add_below (string): This forms the first part of the selector for identifying where to add the comment. Default is 'post'.
      • respond_id (string): The selector for identifying the response comment. This is also added to the link URL as a hash value. Default is 'respond'.
      • reply_text (string): The text for the reply link. Default is ‘Leave a Comment’.
      • login_text (string): The text for the link shown when the user is logged out. Default is ‘Log in to leave a Comment’.
      • before (string): Any text or HTML to be added before the reply link.
      • after (string): Any text or HTML to be added after the reply link.
      • Default for $args: An empty array.
    2. $post (int|WP_Post - optional): This can be a post ID or a WP_Post object indicating the post on which the comment is to be displayed. If not specified, it defaults to the current post.

    Usage Example

    To use get_post_reply_link(), you can specify the necessary parameters according to your needs. Here's an example:

    // Example usage of get_post_reply_link()
    $args = array(
        'add_below'  => 'comment',
        'respond_id' => 'reply-comment',
        'reply_text' => 'Reply to This Comment',
        'login_text' => 'Log in to Reply',
        'before'     => '<div class="reply-link">',
        'after'      => '</div>'
    );
    
    $reply_link = get_post_reply_link( $args, $post_id );
    
    if ( $reply_link ) {
        echo $reply_link;
    } else {
        echo 'Comments are closed.';
    }
    

    In this example, we've set custom values for the $args array and used a specific $post_id. The function returns the HTML for the reply link, which is then echoed to the webpage. If comments are closed, it displays a message indicating so.
