我有一些用于自定义帖子类型的自定义永久链接，如下所示：

/产品/类别/子类别/产品名称

我写了一个generate_rewrite_rules 用于与该自定义帖子类型相关的永久链接的函数。

然而，我通过WP的界面创建的任何常规页面都显示为404，而这些自定义永久链接仍然有效。我确信这是Apache的问题。不知道怎么了。

我有一个可编辑的。htaccess到位，里面有正常的东西。。。

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

相关服务器的apache conf文件：

<Directory />
        Options FollowSymLinks
        AllowOverride All
</Directory>
<Directory /path/to/folder>
        Options Indexes FollowSymLinks MultiViews
        AllowOverride All
        Require all granted
        Order allow,deny
        allow from all
</Directory>

在Ubuntu 14.04上编辑正在运行的WP 4.8.1

编辑2：刚刚注意到这是WP 404，不是apache 404。因此，这取决于我的重写规则，我注意到重写是寻找每个页面作为我的自定义分类法之一，如（index.php？product category=$matches[1]），这就是我得到404的原因。当然，这不应该发生。

如何修复它？我的功能有点像鸟巢。

function custom_rewrite_rules($wp_rewrite) {
    $newRules = array();
    $terms = get_terms( array(
        \'taxonomy\' => \'product-category\',
        \'hide_empty\' => false,
    ) );

    foreach ($terms as $term) {   
        $post_query = new WP_Query( array(
            \'post_type\' => \'custom_product\',
            \'posts_per_page\' => -1,
            \'tax_query\' => array(
                array(

                    \'terms\'    => $term->slug,

        if ( $post_query->have_posts() ) : while ( $post_query->have_posts() ) : $post_query->the_post();
            if($term->parent){
                $parent = get_term( $term->parent, \'product-category\');

        endwhile;
        endif;

            $parent = get_term( $term->parent, \'product-category\');
            $newRules[\'products/\' . $parent->name . \'/\' . $term->name . \'$\'] = \'index.php?taxonomy=product-category&product-category=\'.$parent->slug.\'&product-category=\'.$term->slug;
        } else {
            $newRules[\'products/\' . $term->name . \'$\'] = \'index.php?taxonomy=product-category&product-category=\'.$term->slug;
        }     
    }
    $newRules[\'products/(.+)/(.+)/?$\'] = \'index.php?post_type=custom_product&custom_product=$matches[2]\';
    $newRules[\'products$\'] = \'index.php?post-type=page&pagename=product-categories\';

    $wp_rewrite->rules = $newRules + $wp_rewrite->rules;
