我有一个关于WordPress的分页的问题，这对我来说是陌生的，因为我没有使用它，关于我下面的代码，我有一个名为Portfolio.php的文件，它具有下面的代码：
<?php
/**
* The template for displaying the portfolio component

* @package Certy_Theme

// Prevent direct script access.
if ( ! defined( 'ABSPATH' ) ) {
die( 'No direct script access allowed' );
}
//global

我听说我还需要一些有关功能的信息。我是否可以知道必须在上面的代码中以及在functions.php中添加哪些内容来显示我的分页信息？
谢谢，期待您的回答。

使用paginate_links()。在结束学习之前，先准备好这个。
<?php
$posts_array = get_posts( $args_posts );
foreach($posts_array as $post):setup_postdata($post);
// You Loop
$args = [
'base' => get_pagenum_link(1) . '%_%',
'current' => max(1, get_query_var('paged')),
'total' => $posts_array->max_num_pages,
'prev_text' => __('« prev'),
'next_text' => __('next »')
];
echo paginate_links($args); // Your pagination
endforeach;
