自定义WordPress里标签(tag)和分类目录(category)的固定链接结构的方法
对于Wordpress比较熟悉的朋友应该知道,如果想修改文章(post)的固定链接结构(permalinks),可以到Wordpress后台管理界面进行修改,比如说,如果你想让页面地址都有一个“news”的前缀,形如:
https://www.xyhtml5.com/news/hollow-world/
你可以在后台的“固定链接”设置界面将固定链接结构设置为“/news/%postname%”就行了。
但是,你会发现,只有文章页(post)的链接结构上这样改的,而一般页面(page)的链接结构没有变化,而且,标签(tag)的链接结构也变成了”/news/%tag%”样子。
如果你想让所有的页面(page)的固定链接结构也变成“/news/%pagename%”模式,之前的文章《修改WordPress里页面(page)的固定链接结构的方法》里清楚的介绍了修改的方法。
现在的问题是,如果你想自定义标签(tag)的固定链接,让它不随文章页(post)的链接结构的变化而变化,让标签页(tag)具有更个性的链接结构,怎么办呢?
或者,我还想自定义分类目录页(category)的固定链接结构,有什么办法?
从《修改WordPress里页面(page)的固定链接结构的方法》里可以看出,我们是应该从$wp_rewrite
对象下手。前提是要知道 $wp_rewrite
对象里数据结构究竟是怎样的,才能找出修改的方法,于是我把 $wp_rewrite
打印了出来,下面就是这个对象的内部结构:
WP_Rewrite Object ( [permalink_structure] => /post/%postname%.html [use_trailing_slashes] => [author_base] => author [page_structure] => %pagename%.html [search_base] => search [comments_base] => comments [pagination_base] => page [comments_pagination_base] => comment-page [feed_base] => feed [front] => /post/ [root] => [index] => index.php [matches] => [rules] => [extra_rules] => Array ( ) [extra_rules_top] => Array ( ) [non_wp_rules] => Array ( ) [extra_permastructs] => Array ( [category] => Array ( [with_front] => [ep_mask] => 512 [paged] => 1 [feed] => 1 [forcomments] => [walk_dirs] => 1 [endpoints] => 1 [struct] => cat/%category% ) [post_tag] => Array ( [with_front] => [ep_mask] => 1024 [paged] => 1 [feed] => 1 [forcomments] => [walk_dirs] => 1 [endpoints] => 1 [struct] => tag/%post_tag% ) [post_format] => Array ( [with_front] => 1 [ep_mask] => 0 [paged] => 1 [feed] => 1 [forcomments] => [walk_dirs] => 1 [endpoints] => 1 [struct] => /post/type/%post_format% ) ) [endpoints] => Array ( ) [use_verbose_rules] => [use_verbose_page_rules] => 1 [rewritecode] => Array ( [0] => %year% [1] => %monthnum% [2] => %day% [3] => %hour% [4] => %minute% [5] => %second% [6] => %postname% [7] => %post_id% [8] => %author% [9] => %pagename% [10] => %search% [11] => %category% [12] => %post_tag% [13] => %post_format% ) [rewritereplace] => Array ( [0] => ([0-9]{4}) [1] => ([0-9]{1,2}) [2] => ([0-9]{1,2}) [3] => ([0-9]{1,2}) [4] => ([0-9]{1,2}) [5] => ([0-9]{1,2}) [6] => ([^/]+) [7] => ([0-9]+) [8] => ([^/]+) [9] => ([^/]+?) [10] => (.+) [11] => (.+?) [12] => ([^/]+) [13] => ([^/]+) ) [queryreplace] => Array ( [0] => year= [1] => monthnum= [2] => day= [3] => hour= [4] => minute= [5] => second= [6] => name= [7] => p= [8] => author_name= [9] => pagename= [10] => s= [11] => category_name= [12] => tag= [13] => post_format= ) [feeds] => Array ( [0] => feed [1] => rdf [2] => rss [3] => rss2 [4] => atom ) )
这下就清楚了,之前我们修改页面(page)的固定链接结构是修改了[page_structure] => %pagename%.html
,而修改标签页(tag)的固定链接结构很显然是要修改[extra_permastructs][post_tag][struct] => tag/%post_tag%
这个值,而修改分类目录页(category)的固定链接,自然是修改[extra_permastructs][category][struct] => cat/%category%
的值。
下面是具体的修改代码:
function custom_page_rules() { global $wp_rewrite; //修改page的固定链接结构 $wp_rewrite->page_structure = $wp_rewrite->root . 'post/%pagename%.html'; //修改tag的固定链接结构 $wp_rewrite->extra_permastructs['post_tag']['with_front'] = ''; $wp_rewrite->extra_permastructs['post_tag']['struct'] = 'tag/%post_tag%'; } add_action( 'init', 'custom_page_rules' );
把上面的这段代码放到function.php
里,就能自定义 1)page的固定链接结构,2)tag页的固定链接结构。
修改分类目录页(category)的固定链接也是同样的道理。
严谨的说,Wordpress里并没有提供安全的接口来实现这些修改,上面的这些方法属于不安全的入侵,如果某天Wordpress升级了数据结构,那这些修改方法将会失效,甚至会引起系统错误等,所以,有一定风险。
大家的感觉呢?
