为什么不使用WP中的默认函数。可以使用follow类作为示例。

class fb_pagination_example {

    public function content_nav( $nav_id, $pag_bar = TRUE ) {

        if ( $GLOBALS[\'wp_query\'] -> max_num_pages > 1 ) : ?>
            <nav id="<?php echo $nav_id; ?>">
                <h1 class="assistive-text"><?php _e( \'Post navigation\', WP_BASIS_TXTD ); ?></h1>
                <?php 
                if ( $pag_bar ) {
                    self :: get_paginate_bar();
                } else { ?>
                    <div class="nav-previous"><?php next_posts_link( __( \'<span class="meta-nav">&larr;</span> Older posts\', WP_BASIS_TXTD ) ); ?></div>
                    <div class="nav-next"><?php previous_posts_link( __( \'Newer posts <span class="meta-nav">&rarr;</span>\', WP_BASIS_TXTD ) ); ?></div>
                <?php } ?>
            </nav>
        <?php endif;
    }

    public function get_paginate_bar( $args = FALSE ) {
