1、安装插件

2、找到主题文件夹的functions.php文件中的以下代码

<nav id="<?php echo esc_attr( $html_id ); ?>" class="navigation"> <h3 class="assistive-text"><?php _e( 'Post navigation', 'twentytwelve' ); ?></h3> <div class="nav-previous"><?php next_posts_link( __( '<span class="meta-nav">&larr;</span> Older posts', 'twentytwelve' ) ); ?></div> <div class="nav-next"><?php previous_posts_link( __( 'Newer posts <span class="meta-nav">&rarr;</span>', 'twentytwelve' ) ); ?></div>

替换为：

<?php if(function_exists('wp_pagenavi')) { wp_pagenavi(); } ?>
