paginate_links: 这是一个WordPress的函数,为一个列表中的项目生成分页链接。它接受一个参数数组并返回分页链接的HTML。它可以用来给任何项目列表分页,而不仅仅是评论。

为存档的文章页面检索分页链接。

从技术上讲,该函数可用于为任何区域创建分页链接列表。base”参数用于引用网址,它将被用于创建分页链接。format”参数则用于替换页码。然而,它最有可能也是默认的,被用于存档的文章页面。

type”参数控制返回值的格式。默认的是’plain’,这只是一个字符串,其中的链接由一个换行符隔开。
字符分隔的字符串。其他可能的值是’数组’或’列表’。数组”值将返回一个分页链接列表的数组,以提供对显示的完全控制。list’值将把所有的分页链接放在一个无序的HTML列表中。

total’参数是页面的总量,是一个整数。current’参数是当前页数,也是一个整数。

一个’base’参数的例子是”http://example.com/all_posts.php%_%”,’%_%’是必须的。%_%’将被’format’参数中的内容所取代。format”参数的例子是”?page=%#%”,’%#%’也是必需的。%#%’将被替换成页码。

你可以通过设置’prev_next’参数为”true”,在列表中包含上一个和下一个链接,默认情况下是这样的。你可以设置
前一个文本,通过使用’prev_text’参数。你可以通过设置’next_text’参数来设置下一个文本。

如果’show_all’参数被设置为”true”,那么它将显示所有的页面,而不是当前页面附近的一个简短的页面列表。默认情况下,’show_all’被设置为false,由’end_size’和’mid_size’参数控制。end_size”参数是在列表的开始和结束边缘有多少个数字,默认是1。”mid_size”参数是在当前页的两侧有多少个数字,但不包括当前页。

通过使用’add_args’参数可以向链接添加查询变量,更多信息请参见add_query_arg()。

before_page_number”和”after_page_number”参数允许用户自己增加链接的内容。通常情况下,这可能是为了给编号的链接添加上下文,以便屏幕阅读器用户理解链接的内容。文本字符串被添加到页码的前后–在锚标签内。
