挖鱼源码网之前分享过 将WordPress作者存档链接中的用户名改为昵称，不少朋友都在询问，如果将WordPress作者存档链接中的用户名改为用户ID，好吧，一起来看看 前端博客 的方法吧。

什么是作者存档页链接

wordpress的里的所有注册用户都有一个专属的链接，称之为作者存档页链接，通常是这样的：

1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7

// 未url重写   http://qianduanblog.com/?author=1   // 已url重写   http://qianduanblog.com/author/admin 1 2 3 4 5 6 7 // 未url重写   http://qianduanblog.com/?author=1   // 已url重写   http://qianduanblog.com/author/admin

// 未url重写 http://qianduanblog.com/?author=1 // 已url重写 http://qianduanblog.com/author/admin

其中未url重写的参数值是用户id，而url重写后的参数值是用户名。通常，我们都使用了url重写，而作者存档页链接暴露了用户名，可能对wordpress的安全性有点点倾斜（而作者的想法是作者的的参数值统一为用户id，如：author/123，用户页面链接的参数值统一为用户id，如：user/123，关于用户页面链接比作者存档页链接要复杂，后续文章再说），所以我们需要修改参数值为用户id。

修改作者存档页链接

首先要做的是，修改存档页链接，如下示例：

1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7

// 修改之前   http://qianduanblog.com/author/admin   // 修改之后   http://qianduanblog.com/author/123 1 2 3 4 5 6 7 // 修改之前   http://qianduanblog.com/author/admin   // 修改之后   http://qianduanblog.com/author/123

// 修改之前 http://qianduanblog.com/author/admin // 修改之后 http://qianduanblog.com/author/123

在wordpress里内置了关于作者存档页链接的钩子，原始的作者存档页链接是这样获取的：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29

修改之后，在前台输出作者存档页的链接：

get_author_posts_url(1);
// =>http://qianduanblog.com/author/1

说明钩子使用的是正确的，但当我们打开这个链接的时候，出现了404。这是因为，原始的作者存档页链接的url重写规则是根据用户名来的，而现在修改为了用户id，重写规则不匹配，出现了404。

修改作者存档页查询变量

为了避免出现404，我们需要修改作者存档页的url重写规则。

if ( $author_id ) {
$query_vars[‘author’] = $author_id;
unset( $query_vars[‘author_name’] );
}
}
return $query_vars;
}

很巧合的是，作者存档页的查询变量有2个，之前说过，1个是url未重写的用户id（author），另一个是url已重写的用户名（author_name），而现在直接传递过来了用户id，只需要把参数名称author_name修改为author即可。

再次打开刚才的链接（http://qianduanblog.com/author/1），出现了正确页面。而如果打开原始的链接（http://qianduanblog.com/author/admin）就会出现404页面了，说明我们的修改正确了。
