wordpress免插件分页，wordpress自带函数：the_posts_pagination
<?php the_posts_pagination( array( 'mid_size' => 3, 'prev_text' =>'上一页', 'next_text' =>'下一页', 'before_page_number' => '<span class="meta-nav screen-reader-text">第 </span>', 'after_page_number' => '<span class="meta-nav screen-reader-text"> 页</span>', ) ); ?>
