He aquí la función de paginate (); que usamos en options-plugins
query_vars['paged'] > 1 ? $current = $wp_query->query_vars['paged'] : $current = 1; $pagination = array( 'base' => @add_query_arg('page','%#%'), 'format' => '', 'total' => $wp_query->max_num_pages, 'current' => $current, 'show_all' => true, 'type' => 'list', 'next_text' => '»', 'prev_text' => '«' ); if( $wp_rewrite->using_permalinks() ) $pagination['base'] = user_trailingslashit( trailingslashit( remove_query_arg( 's', get_pagenum_link( 1 ) ) ) . 'page/%#%/', 'paged' ); if( !empty($wp_query->query_vars['s']) ) $pagination['add_args'] = array( 's' => get_query_var( 's' ) ); echo paginate_links( $pagination ); } ?>
Y para mostrar la paginación en la página del tema se debe de poner este PHP:
max_num_pages ); if($max > $i){ echo ""; } ?>
