我必须在不使用wp_query的情况下从wordpress数据库中获取标题,描述和附件。我不知道如何同时获取两者,附件和meta_descriptions ......
这是我的查询到目前为止的样子
$query="SELECT post_title, meta_value
FROM wp_posts p JOIN wp_postmeta pm ON p.ID=pm.post_id
WHERE post_status='publish'
AND post_type='page'
AND post_parent=2330
AND ( meta_key='_wpseo_edit_description' OR meta_key='_wp_attached_file' )
ORDER BY post_date DESC";
此查询返回“doubled”结果,我必须在循环中拆分
______________________________
| post_title | meta_value |
|------------|---------------|
| title 1 | 1349 |
|------------|---------------|
| title 1 | description 1 |
|------------|---------------|
| title 2 | 1348 |
|------------|---------------|
| title 2 | description 2 |
|____________|_______________|

您需要加入wp_postmeta
表格才能获取任何附加信息,例如文件附件或自定义字段。
如何执行此操作的示例:
SELECT p.*, pm2.meta_value AS featured_image, pm3.meta_value AS wpseo_edit_description, pm4.meta_value AS wp_attached_file
FROM `wp_posts` p
LEFT JOIN `wp_postmeta` pm2 ON p.ID = pm2.post_id AND pm2.meta_key = 'wp_attached_file'
LEFT JOIN `wp_postmeta` pm3 ON p.ID = pm3.post_id AND pm3.meta_key = '_wpseo_edit_description'
LEFT JOIN `wp_postmeta` pm4 ON p.ID = pm4.post_id AND pm4.meta_key = '_wp_attached_file'
WHERE p.post_status = 'publish'
AND p.post_type = 'page'
AND p.post_parent = 2330
然后可以使用正常的帖子字段(帖子标题,说明,ID等),以及featured_image
,wp_attached_file
和wpseo_edit_description
。
