Альтернатива фукнции пагинации paginate_links()
paginate_links() всегда возвращает HTML, даже если параметр type=array вы получите массив готовых <a> тегов. Это может не подойти когда нужно полностью изменить HTML-структуру вашей пагинации. Ниже небольшая функция, которая возвращает массив объектов вместо HTML.
/**
* Generates array of pagination links.

* @author Kama (wp-kama.com)
* @varsion 2.5
*
* @param array $args {
*
* @type int $total Maximum allowable pagination page.
* @type int $current Current page number.
* @type string $url_base URL pattern. Use `{pagenum}` placeholder.
* @type string $first_url URL to first page. Default: '' - taken automaticcaly from $url_base.
* @type int $mid_size Number of links before/after current: 1 ... 1 2 [3] 4 5 ... 99. Default: 2.
* @type int $end_size Number of links at the edges: 1 2 ... 3 4 [5] 6 7 ... 98 99. Default: 1.
* @type bool $show_all true - Show all links. Default: false.
* @type string $a_text_patt `%s` will be replaced with number of pagination page. Default: `'%s'`.
* @type bool $is_prev_next Whether to show prev/next links. « Previou 1 2 [3] 4 ... 99 Next ». Default: false.
* @type string $prev_text Default: `« Previous`.

Теперь используем эту функцию в цикле:
<?php
$links_data = kama_paginate_links_data( [
'total' => 3,
'current' => 2,
'url_base' => 'http://site.com/page-name/paged/{pagenum}',
] );
if( $links_data ){
?>
<ul>
<?php foreach( $links_data as $link ) { ?>
<li>
<?php if ( $link->is_dots ) { ?>
<span><?= $link->link_text ?></span>
<?php } elseif ( $link->is_current ) { ?>
<strong><?= $link->link_text ?></strong>
<?php } else { ?>
<a href="<?php esc_attr_e( $link->url ) ?>"><?php _e( $link->link_text ) ?></a>
<?php } ?>
</li>
<?php } ?>
</ul>
<?php
}
Получим:
<ul> <li> <a href="http://site.com/page-name/paged/1">1</a> </li> <li> <strong>2</strong> </li> <li> <a href="http://site.com/page-name/paged/3">3</a> </li> </ul>
