WordPress 分页链接函数 paginate_links

例如自定义查询

当查询新WP_Query循环设置' total'参数到max_num_pages该WP_Query对象的属性。
自定义查询的例子：

<?php
//Protect against arbitrary paged values
$paged = ( get_query_var( 'paged' ) ) ? absint( get_query_var( 'paged' ) ) : 1;

$args = array(
	'posts_per_page' => 5,
	'category_name' => 'gallery',
	'paged' => $paged,
);

$the_query = new WP_Query( $args );
?>
<!-- the loop etc.. -->

适应于上面的自定义查询paginate_links参数例如：

<?php
$big = 999999999; // need an unlikely integer

echo paginate_links( array(
	'base' => str_replace( $big, '%#%', esc_url( get_pagenum_link( $big ) ) ),
	'format' => '?paged=%#%',
	'current' => max( 1, get_query_var('paged') ),
	'total' => $the_query->max_num_pages
) );
?>

改善无障碍
要添加上下文编号的链接，以确保屏幕阅读器用户了解哪些环节是：

<?php
global $wp_query;

$big = 999999999; // need an unlikely integer
$translated = __( 'Page', 'mytextdomain' ); // Supply translatable string

echo paginate_links( array(
	'base' => str_replace( $big, '%#%', esc_url( get_pagenum_link( $big ) ) ),
	'format' => '?paged=%#%',
	'current' => max( 1, get_query_var('paged') ),
	'total' => $wp_query->max_num_pages,
        'before_page_number' => '<span class="screen-reader-text">'.$translated.' </span>'
) );
?>
