在我目前的项目中，我正在使用get_posts，并希望显示分页，但我无法实现这一目标。有人建议使用WP_Query，但我现在不想更改我的代码，是否有人知道如何在get_posts函数中显示分页？

它庞大的代码，这就是为什么我无法在WP_Query中工作的原因：（
答案 0 :(得分：0)
尝试更改查询参数，例如$ args：
$args = array(
'posts_per_page' => 3,
'post_type' => 'post',
'paged' => ( get_query_var('paged') ? get_query_var('paged') : 1 )
);
然后在循环后把这个：
if (function_exists('wp_pagenavi')) {
wp_pagenavi();
}
