帮助实现分层自定义分类和固定链接...几乎就在那里

时间：2012-05-03 作者：flashape

我正在尝试让permalinks使用自定义分类法和自定义帖子类型。按照说明操作here 我能让它几乎正常工作，但有一个小故障。

注册分类的代码如下所示：

$args = array( 
    \'labels\' => $labels,
    \'public\' => true,
    \'show_in_nav_menus\' => false,
    \'show_ui\' => true,
    \'show_tagcloud\' => true,
    \'hierarchical\' => true,
    \'rewrite\' => array(\'slug\' => \'products\', \'hierarchical\' => true, \'with_front\' => true),
    // \'rewrite\' => true,
    \'query_var\' => true
);

register_taxonomy( \'tc_product_type\', array(\'tc_products\'), $args );
注册帖子类型的代码：

$post_type_args = array(
    \'labels\'            => $labels,
    \'singular_label\'    => __(\'Product\'),
    \'public\'            => true,
    \'show_ui\'           => true,
    \'publicly_queryable\'=> true,
    \'query_var\'         => true,
    \'capability_type\'   => \'post\',
    \'has_archive\'       => true,
    \'hierarchical\'      => true,
    \'rewrite\'           => array(\'slug\' => \'products/%taxonomy_name%/\'),
    // \'rewrite\'            => array(\'slug\' => \'products\', \'with_front\' => false),
    \'supports\'          => $supports,
    \'menu_position\'     => 0,
    \'taxonomies\' => array(\'post_tag\')
 );


register_post_type(\'tc_products\',$post_type_args);
permalinks本身创建得很好，查看分类页面也很好，但在网站上查看帖子时，我得到了404。我转储了WP\\u查询，它似乎使用permalink URI的最后一段作为tc\\u product\\u类型，而不是post slug（在post slug为“77777-2”的情况下）：

    WP_Query::__set_state(array(
   \'query_vars\' => 
  array (
    \'tc_product_type\' => \'77777-2\',
    \'error\' => \'\',

我是不是错过了什么？如何告诉WP最后一段是页面段塞？

编辑：忘记了一些重要的事情。在上面链接的帖子中，他创建了重写规则，知道页面段塞将始终位于永久链接中的特定段。这在我的情况下行不通，因为每个分类下都会有帖子。。。这意味着我不知道弹头的确切位置（当然，除了它将是末端）。是否有覆盖该场景的重写规则？它如何知道最后一段是分类法还是后段？

编辑2：添加相关重写规则的转储：

array (
 \'products/%taxonomy_name%/?$\' => \'index.php?%taxonomy_name%$matches[1]\',
 \'products/%taxonomy_name%/feed/(feed|rdf|rss|rss2|atom)/?$\' => \'index.php?%taxonomy_name%$matches[1]&feed=$matches[2]\',
 \'products/%taxonomy_name%/(feed|rdf|rss|rss2|atom)/?$\' => \'index.php?%taxonomy_name%$matches[1]&feed=$matches[2]\',
 \'products/%taxonomy_name%/page/([0-9]{1,})/?$\' => \'index.php?post_type=tc_products&paged=$matches[1]\',

/*...more rules, then...*/

 \'products/(.+?)/feed/(feed|rdf|rss|rss2|atom)/?$\' => \'index.php?tc_product_type=$matches[1]&feed=$matches[2]\',
 \'products/(.+?)/(feed|rdf|rss|rss2|atom)/?$\' => \'index.php?tc_product_type=$matches[1]&feed=$matches[2]\',
 \'products/(.+?)/page/?([0-9]{1,})/?$\' => \'index.php?tc_product_type=$matches[1]&paged=$matches[2]\',
 \'products/(.+?)/?$\' => \'index.php?tc_product_type=$matches[1]\',

/*...more rules, then...*/


 \'products/%taxonomy_name%/.+?/attachment/([^/]+)/?$\' => \'index.php?attachment=$matches[1]\',
 \'products/%taxonomy_name%/.+?/attachment/([^/]+)/trackback/?$\' => \'index.php?attachment=$matches[1]&tb=1\',
 \'products/%taxonomy_name%/.+?/attachment/([^/]+)/feed/(feed|rdf|rss|rss2|atom)/?$\' => \'index.php?attachment=$matches[1]&feed=$matches[2]\',

 \'products/%taxonomy_name%/.+?/attachment/([^/]+)/comment-page-([0-9]{1,})/?$\' => \'index.php?attachment=$matches[1]&cpage=$matches[2]\',
 \'products/%taxonomy_name%/(.+?)/trackback/?$\' => \'index.php?%taxonomy_name%$matches[1]&tc_products=$matches[2]&tb=1\',
 \'products/%taxonomy_name%/(.+?)/feed/(feed|rdf|rss|rss2|atom)/?$\' => \'index.php?%taxonomy_name%$matches[1]&tc_products=$matches[2]&feed=$matches[3]\',
 \'products/%taxonomy_name%/(.+?)/(feed|rdf|rss|rss2|atom)/?$\' => \'index.php?%taxonomy_name%$matches[1]&tc_products=$matches[2]&feed=$matches[3]\',
 \'products/%taxonomy_name%/(.+?)/page/?([0-9]{1,})/?$\' => \'index.php?%taxonomy_name%$matches[1]&tc_products=$matches[2]&paged=$matches[3]\',
 \'products/%taxonomy_name%/(.+?)/comment-page-([0-9]{1,})/?$\' => \'index.php?%taxonomy_name%$matches[1]&tc_products=$matches[2]&cpage=$matches[3]\',
 \'products/%taxonomy_name%/(.+?)(/[0-9]+)?/?$\' => \'index.php?%taxonomy_name%$matches[1]&tc_products=$matches[2]&page=$matches[3]\',
 \'products/%taxonomy_name%/page/?([0-9]{1,})/?$\' => \'index.php?%taxonomy_name%$matches[1]&paged=$matches[2]\',
 \'products/%taxonomy_name%/comment-page-([0-9]{1,})/?$\' => \'index.php?%taxonomy_name%$matches[1]&cpage=$matches[2]\',
/*...more rules...*/
)
它似乎符合以下规则：

 \'products/(.+?)/?$\' => \'index.php?tc_product_type=$matches[1]\',
不知道如何使其与其他规则匹配，或者其他规则是否有效。

好的，我通过挂接到“请求”过滤器，然后检查最后一段是否为term来实现它。如果不是，请更改$请求变量：

function alter_the_query( $request ) {
    $dummy_query = new WP_Query();  // the query isn\'t run if we don\'t pass any query vars
    $dummy_query->parse_query( $request );

    if ( !$dummy_query->is_admin && isset($request[\'tc_product_type\']) ){       
        $lastSegment = basename($request[\'tc_product_type\']);
        if(get_term_by(\'slug\',$lastSegment,  \'tc_product_type\') === FALSE){
            $request[\'post_type\'] = \'tc_products\';
            $request[\'tc_products\'] = $lastSegment;
            $request[\'name\'] = $lastSegment;
        }
    }

    return $request;
}
add_filter( \'request\', \'alter_the_query\' );

结束

使用新的WP-Query()从循环中过滤后期格式；

嗨，我目前正在为我的博客构建一个主题。下面的代码指向最新的帖子（特色帖子）。因为这将有一个不同的风格比所有其他职位。然而我想过滤掉帖子格式：链接使用我在循环中定义的WP查询，因为它给我带来了更多的灵活性。我该怎么做呢？ <?php $featured = new WP_Query(); $featured->query(\'showposts=1\'); ?> <?php while ($featured->have_post
