分页式导航调用函数：

<?php
    the_posts_pagination( array(
        'prev_text'          =>上页,
        'next_text'          =>下页,
        'before_page_number' => '<span class="meta-nav screen-reader-text">第 </span>',
        'after_page_number' => '<span class="meta-nav screen-reader-text"> 页</span>',
    ) );
?>

// 翻页
function weihuan_paginate(){
    $args = array(
        'prev_next'          => 0,
        'format'       => '?paged=%#%',
        'before_page_number' => '',
        'mid_size'           => 2,
        'current' => max( 1, get_query_var('paged') ),
        'prev_next'    => True,
        'prev_text'    => __('上一页'),
        'next_text'    => __('下一页'),
    );
    $page_arr=paginate_links($args); 
    if ($page_arr) {
        echo $page_arr;
    }else{
        echo "没有下一页了……";
