使用wp_postmeta自定义查询wp_posts

Question

在postmeta中可以说

  

  
1. meta_key =＆＃39; count＆＃39;和meta_value =＆＃39; 5＆＃39;
  
2. meta_key =＆＃39; count＆＃39;和meta_value =＆＃39; 6＆＃39;
  
3. meta_key =＆＃39; count＆＃39;和meta_value =＆＃39; 7＆＃39;
  

现在我想获得所有帖子

WHERE meta_key = 'count'

AND orderby = 'meta_value_num'

AND order by ASC

注意：我不想使用query_posts或wp_query。只是自定义SQL查询。 提前致谢。

Answer 1

试试这个：

SELECT wposts.*, postmeta.*
FROM wp_posts as wposts
LEFT JOIN wp_postmeta as postmeta ON (postmeta.post_id = wposts.ID)
WHERE wposts.post_type = 'post'
AND wposts.post_status = 'publish' 
AND postmeta.meta_key = 'count'
ORDER BY postmeta.meta_value ASC

此处wp_是数据库表的前缀，您可以将其替换为您自己的数据库表前缀。
