我有4种自定义帖子类型：
服务 常见问题解答 价格 之前和之后
我希望能够在每个帖子类型中使用相同的帖子名称，例如：
服务
皮肤（example.com/Services/skin）
奶油 （example.com/Services/cream）
正文（example.com/Services/body）常见问题
皮肤（example.com/FAQs/skin）
奶油 （example.com/FAQs/cream）
正文（example.com/FAQs/body）价格
皮肤（example.com/Prices/skin）
奶油 （example.com/Prices/cream）
正文（example.com/Prices/body）之前和之后
皮肤（example.com/before-and-after/skin）
奶油 （example.com/before-and-after/cream）
正文（example.com/before-and-after/body）
我该怎么做？现在，如果我创建一个与当前名称相同的新帖子，它会添加一个＆＃34; -2＆＃34;或＆＃34; -3＆＃34;到帖子结尾：
坏：
example.com/services/body
example.com/faqs/body-2
example.com/prices/body-3
example.com/before-and-after/body-4
有人请帮助!!!!!

我编写了一个可以添加到主题的functions.php文件中的函数，该文件包含此票证中由mboynes编写的补丁：http://core.trac.wordpress.org/ticket/18962#comment:14
function wp_cpt_unique_post_slug($slug, $post_ID, $post_status, $post_type, $post_parent, $original_slug) {

$wp_slug = $slug;
// reset slug to original slug
$slug = $original_slug;

我认为这是wordpress程序员团队尚未解决的问题。 以下是其他一些解释：Allow duplicate slugs for different content
我在这个函数中找到了一个不正确的编写代码：wp_unique_post_slug位于核心文件（wp_includes / post.php）中，检查插入的永久链接是否唯一。
不幸的是，我被迫破解核心代码来修复bug。 我已经替换了从第2859行开始的代码部分：
} elseif ( in_array( $post_type, $hierarchical_post_types ) ) {
// Page slugs must be unique within their own trees. Pages are in a separate
// namespace than posts so page slugs are allowed to overlap post slugs.
$check_sql = "SELECT post_name FROM $wpdb->posts WHERE post_name = %s AND post_type IN ( '" . implode( "', '", esc_sql( $hierarchical_post_types ) ) . "' ) AND ID != %d AND post_parent = %d LIMIT 1";
$post_name_check = $wpdb->get_var( $wpdb->prepare( $check_sql, $slug, $post_ID, $post_parent ) );
if ( $post_name_check || in_array( $slug, $feeds ) || preg_match( "@^($wp_rewrite->pagination_base)?\d+$@", $slug ) || apply_filters( 'wp_unique_post_slug_is_bad_hierarchical_slug', false, $slug, $post_type, $post_parent ) ) {
$suffix = 2;
do {
$alt_post_name = substr( $slug, 0, 200 - ( strlen( $suffix ) + 1 ) ) . "-$suffix";
$post_name_check = $wpdb->get_var( $wpdb->prepare( $check_sql, $alt_post_name, $post_ID, $post_parent ) );
$suffix++;
} while ( $post_name_check );
$slug = $alt_post_name;
}
}
我写的这段代码：
} elseif ( in_array( $post_type, $hierarchical_post_types ) ) {
// HACK
foreach($hierarchical_post_types as $pt){
// Page slugs must be unique within their own trees. Pages are in a separate
// namespace than posts so page slugs are allowed to overlap post slugs.
// HACK
$check_sql_andrea = "SELECT post_name FROM $wpdb->posts WHERE post_name = %s AND post_type = %s AND ID != %d AND post_parent = %d LIMIT 1";
// HACK
$post_name_check = $wpdb->get_var( $wpdb->prepare( $check_sql_andrea, $slug, $pt, $post_ID, $post_parent ) );
if ( $post_name_check || in_array( $slug, $feeds ) || preg_match( "@^($wp_rewrite->pagination_base)?\d+$@", $slug ) || apply_filters( 'wp_unique_post_slug_is_bad_hierarchical_slug', false, $slug, $post_type, $post_parent ) ) {
$suffix = 2;
do {
$alt_post_name = substr( $slug, 0, 200 - ( strlen( $suffix ) + 1 ) ) . "-$suffix";
// HACK
$post_name_check = $wpdb->get_var( $wpdb->prepare( $check_sql_andrea, $alt_post_name, $pt, $post_ID, $post_parent ) );
$suffix++;
} while ( $post_name_check );
$slug = $alt_post_name;
break;
}
}// END HACK
}
请......任何人都应该知道案件的任何其他解决方案，或者更重要的是，如果有人知道会影响我找到的解决方案的任何不可预测的后果，请告诉我，我将非常感激！

只有一种解决方案。您的帖子需要唯一标识符（slug），并且在网址中的名称不能相同。除非他们是等级的。你可以使用自定义帖子类型来做到这一点。使用：
register_post_type(
'customposttype',
array(
'label' => '...',
'description' => '...',
'public' => true,
'exclude_from_search' => false,
'hierarchical' => true, ...
然后，您将能够使用不同的自定义帖子类型具有相同的名称

我搜索了其他对这个问题的引用（它也发生在subcategories for different parent categories）并且甚至标记为enhancement for future release，在该票证中，我找到了对函数的引用 wp_unique_post_slug 。也许你应该看看它并找出解决当前WP不当行为的方法。
一个脏的解决方案可能是重新检查完整的slug输出，如果没有重复，修剪添加的数字后缀，但我很新手阅读 WP源代码提供更多建议。

一种解决方案可能是将rewrite的{{1}}规则更改为false。例如，如果您设置
with_front你应该能够在每个类别/分类中使用相同的类别/分类而不会发生冲突。
根据您正在做的事情，您可能还必须为每个自定义帖子类型定义一个唯一的分类。
