Member Name

first, congratulations on the plugin.

i am trying to get the members name, i tried that.

/**
 * Parses custom content tags in WordPress Popular Posts.
 *
 * @param  string  $html    The HTML markup from the plugin.
 * @param  integer $post_id The post/page ID.
 * @return string
 */
function wpp_parse_tags_in_popular_posts($html, $post_id){

    // Replace custom content tag {member_name} with
    // the stock member as generated by WordPress
    if ( false !== strpos($html, '{member_name}') ) {
        // Get member
        $member_name = get_member_name($post_id');

        if ( $member_name ) {
            // Replace {member_name} with the actual member
            $html = str_replace('{member_name}', $member_name, $html);
        }
    }

    return $html;

}
add_filter("wpp_parse_custom_content_tags", "wpp_parse_tags_in_popular_posts", 10, 2);

$args = array(
    'wpp_start' => '<div class="slider">',
    'wpp_end' => '</div>',
    'post_html' => '<div class="item">{member_name}</div>',
    'thumbnail_width' => 500,
    'thumbnail_height' => 'auto',
    'limit' => 100,
    'range' => 'last24hours',
    'post_type' => 'post'
);

wpp_get_mostpopular( $args );

                  $songId = get_the_ID();
                  $memberId = get_post_meta($songId, '_member_name', true);
                  if($memberId != ""){
                    $get_member_name = new WP_Query( array( 
                        'post_type' => 'member',
                        'posts_per_page' => -1,
                        'p' => $memberId,
                    ));
                    if( $get_member_name->have_posts() ) : 
                        while( $get_member_name->have_posts() ) : $get_member_name->the_post(); 
                        $member_name = get_the_title();
                        $member_link = get_permalink();
                    endwhile;
