WordPress“自定义帖子类型”设置了错误的分类术语 ID

Question

首先，也是最重要的，我需要强调，我非常感谢任何花时间回复的人 - 提前谢谢您，谢谢您！

我觉得图片对于解释事物很有帮助，所以首先，这里有一些问题的说明：

https://i.sstatic.net/b9OXR.png

前言：

• 我的网站在“dir_listing”自定义帖子类型下有大约 400 个帖子
• 每个“dir_listing”帖子都可以与条款相关联从“列表类别”自定义分类法和/或“listing_region”自定义分类法中，
• 我有大约 210 个“listing_category”术语和 155 个“列表区域”术语

问题摘要：

在发布或更新“ dir_listing”帖子类型，有时术语 ID 会毫无问题地记录到“term_relationships”表中，而其他时候则记录错误。

即便如此，当我返回编辑“dir_listing”帖子类型之一时，所需父/子术语的复选框已正确标记。

可能相关的操作？

• 许多“listing_category”术语已被改组。 （例如，父术语已成为子术语，反之亦然，或者子术语已移至另一个父术语。）

• ）子条款已重命名，但未对“dir_listing”帖子类型进行任何更改。 （我认为这并不重要，因为帖子应该通过 ID 号与条款相关）

• 许多父条款和子条款可能已被其他管理员级别用户删除。 “listing_regions”分类法的子条款似乎也会发生这种情况。

我如何调查/尝试修复它：

• 广泛搜索 WordPress trac（未报告类似问题）

• 搜索 Google对于诸如 *“wordpresstax_input bug”*、“wordpress 分类法 ID 错误”、“wordpress 自定义分类法错误” 等，但没有发现匹配的问题

• 禁用所有插件、自定义重写和其他分类法

  禁用

• 确保复选框输入具有正确的分类法作为其“名称”和术语 ID 作为其“值”< /p>

• 破解了 /wp-admin/includes/post.php 核心文件以尝试自行修复。 （不走运。）

• 今天早上已将问题发布到 [WordPress“操作方法和故障排除”论坛][3]（没有回复）

• 今天下午在 Reddit /r/web_design 发布了问题（也没有回复）

我已经花了8 个小时的大部分时间试图确定其原因，或者如果我错过了使用自定义 MySQL 查询直接获取与特定术语 ID 相关的帖子列表的步骤。

再次强调，非常感谢任何人的想法或建议 - 谢谢！

此信息可能会帮助您了解 term_id 和 term_taxonomy_id 的工作原理。似乎有很多条件会影响 id 设置方式的最终结果。

请参阅此处的完整参考： http://phpxref.com/xref /wordpress/wp-includes/taxonomy.php.html#wp_insert_term

另请参阅 此 trac 票证涉及帖子关系表的需求和一些用例。

get_term($term, $taxonomy, $output = OBJECT, $filter = 'raw')   X-Ref
Get all Term data from database by Term ID.

The usage of the get_term function is to apply filters to a term object. It
is possible to get a term object from the database before applying the
filters.

$term ID must be part of $taxonomy, to get from the database. Failure, might
be able to be captured by the hooks. Failure would be the same value as $wpdb
returns for the get_row method.

There are two hooks, one is specifically for each term, named 'get_term', and
the second is for the taxonomy name, 'term_$taxonomy'. Both hooks gets the
term object, and the taxonomy name as parameters. Both hooks are expected to
return a Term object.

'get_term' hook - Takes two parameters the term Object and the taxonomy name.
Must return term object. Used in get_term() as a catch-all filter for every
$term.

'get_$taxonomy' hook - Takes two parameters the term Object and the taxonomy
name. Must return term object. $taxonomy will be the taxonomy name, so for
example, if 'category', it would be 'get_category' as the filter name. Useful
for custom taxonomies or plugging into default taxonomies.

param: int|object $term If integer, will get from database. If object will apply filters and return $term.
param: string $taxonomy Taxonomy name that $term is part of.
param: string $output Constant OBJECT, ARRAY_A, or ARRAY_N
param: string $filter Optional, default is raw or no WordPress defined filter will applied.
return: mixed|null|WP_Error Term Row from database. Will return null if $term is empty. If taxonomy does not

get_term_by($field, $value, $taxonomy, $output = OBJECT, $filter = 'raw')   X-Ref
Get all Term data from database by Term field and data.

Warning: $value is not escaped for 'name' $field. You must do it yourself, if
required.

The default $field is 'id', therefore it is possible to also use null for
field, but not recommended that you do so.

If $value does not exist, the return value will be false. If $taxonomy exists
and $field and $value combinations exist, the Term will be returned.

param: string $field Either 'slug', 'name', or 'id'
param: string|int $value Search for this term value
param: string $taxonomy Taxonomy Name
param: string $output Constant OBJECT, ARRAY_A, or ARRAY_N
param: string $filter Optional, default is raw or no WordPress defined filter will applied.
return: mixed Term Row from database. Will return false if $taxonomy does not exist or $term was not found.

get_term_children( $term_id, $taxonomy )   X-Ref
Merge all term children into a single array of their IDs.

This recursive function will merge all of the children of $term into the same
array of term IDs. Only useful for taxonomies which are hierarchical.

Will return an empty array if $term does not exist in $taxonomy.

param: string $term ID of Term to get children
param: string $taxonomy Taxonomy Name
return: array|WP_Error List of Term Objects. WP_Error returned if $taxonomy does not exist
