WordPress 自定义永久链接结构:页面、帖子和自定义帖子类型

我正在尝试根据自定义父/子分类法为自定义帖子类型设置自定义永久链接结构。我已经成功实现了这一目标,但我破坏了页面和帖子的永久链接结构。

我已经完成了以下操作:

mysite.com/taxonomy_parent/taxonomy_child/postname

换句话说,我已经删除了分类法,并且 URL 显示了正确的层次结构顺序。首先,我在注册自定义分类法和自定义帖子类型时设置“重写”参数:

对于自定义分类法:

'rewrite' => array( 'slug' => '', 'with_front' => false, 'hierarchical' => true ),

对于帖子类型:

'rewrite' => array( 'slug' => '%mytaxonomy%', 'with_front' => false, 'hierarchical' => true ),

然后我添加了以下代码以获得在中显示父/子分类法的支持网址。

add_filter('rewrite_rules_array', 'mmp_rewrite_rules');
function mmp_rewrite_rules($rules) {
    $newRules  = array();
    $newRules['(.+)/(.+)/(.+)/?$'] = 'index.php?myposttype=$matches[3]';
    $newRules['(.+)/?$']           = 'index.php?mytaxonomy=$matches[1]';
    return array_merge($newRules, $rules);
}
function filter_post_type_link($link, $post)
{
    if ($post->post_type != 'myposttype')
        return $link;
    if ($cats = get_the_terms($post->ID, 'mytaxonomy'))
    {
        $link = str_replace('%mytaxonomy%', get_taxonomy_parents(array_pop($cats)->term_id, 'mytaxonomy', false, '/', true), $link);
    }
    return $link;
}
add_filter('post_type_link', 'filter_post_type_link', 10, 2);
function get_taxonomy_parents($id, $taxonomy, $link = false, $separator = '/', $nicename = false, $visited = array()) {    
    $chain = '';   
    $parent = &get_term($id, $taxonomy);
    if (is_wp_error($parent)) {
        return $parent;
    }
    if ($nicename)    
        $name = $parent -> slug;        
else    
        $name = $parent -> name;
    if ($parent -> parent && ($parent -> parent != $parent -> term_id) && !in_array($parent -> parent, $visited)) {    
        $visited[] = $parent -> parent;    
        $chain .= get_taxonomy_parents($parent -> parent, $taxonomy, $link, $separator, $nicename, $visited);
    }
    if ($link) {
        // nothing, can't get this working :(
    } else    
        $chain .= $name . $separator;
    return $chain;    
}

这很好用,但与帖子和页面的自定义永久链接存在冲突。我也需要配置一下。实际上,我需要“mysite.com/blog/category/postname”和“mysite.com/pagename”。就像设置一个像“/%category%/%postname%/”这样的自定义永久链接一样简单,它可以正常工作,但是当我解释的必要的当前配置在我的functions.php中设置时,会返回404错误页面

我想有一个rewrite_rules 有问题,但不知道如何修复它或如何设置新规则来支持我的自定义 post_type/自定义分类永久链接结构,同时帖子和页面的自定义永久链接结构正常工作。

I'm trying to set a custom permalink structure for a custom post type based on a custom parent/child taxonomy. I've managed to achieve the thing but I broke the permalink structure for pages and posts.

I've accomplisged the following:

mysite.com/taxonomy_parent/taxonomy_child/postname

In other words, I've remove the taxonomy slug and the URL show the correct hierarchical order. First, I set the 'rewrite' arg when registering the custom taxonomy and the custom post-type:

for the custom taxonomy:

'rewrite' => array( 'slug' => '', 'with_front' => false, 'hierarchical' => true ),

for the post type:

'rewrite' => array( 'slug' => '%mytaxonomy%', 'with_front' => false, 'hierarchical' => true ),

Then I added the following code in order to get support to show the parent/child taxonomy in the URL.

add_filter('rewrite_rules_array', 'mmp_rewrite_rules');
function mmp_rewrite_rules($rules) {
    $newRules  = array();
    $newRules['(.+)/(.+)/(.+)/?

This works great but there's a conflict with the custom permalink for the posts and pages. I need to configure that too. Actually, I need "mysite.com/blog/category/postname" and "mysite.com/pagename". As easy as to set a custom permalink like that "/%category%/%postname%/" works properly but a 404 error page is returned when the necessary current config I've explained is set in my functions.php

I suppose there's a problem with rewrite_rules but don't know how to fix it or how to set new rules to support my custom post_type/custom taxonomy permalink structure at the same time the custom permalink structure for posts and pages works properly.

] = 'index.php?myposttype=$matches[3]'; $newRules['(.+)/?
