php - WordPress mysql 查询也可获取特色图像

Question

所以我有以下有效的查询，但我还需要帖子特色图像，你们也可以帮我查询一下吗？

SELECT SQL_CALC_FOUND_ROWS wp_posts.* FROM wp_posts, wp_term_relationships, wp_terms WHERE wp_posts.ID = wp_term_relationships.object_id AND wp_posts.post_status = 'publish' AND wp_terms.term_id = wp_term_relationships.term_taxonomy_id GROUP BY wp_posts.ID ORDER BY wp_posts.post_date DESC LIMIT 0,100

我最近不得不检索最新的 4 篇带有精选图片的帖子，发现这确实相当困难。这段代码对我有用(最终)我知道它可能不准确，但不可能在评论中发布，我相信它会有所帮助:

SELECT title, name, date, content, CONCAT(LEFT(image, LENGTH(image) - LOCATE('.', REVERSE(image))),'-768x576.',SUBSTRING_INDEX(image, '.', -1)) AS image
            FROM (
             SELECT    
             p.post_title AS title, 
             p.post_status AS 'status', 
             p.post_date AS date,
             p.post_content AS content,
             p.post_name AS name,
             (SELECT `guid` FROM wp_posts WHERE id = m.meta_value) AS image
             FROM wp_posts p, wp_postmeta m
             WHERE p.post_type = 'post'
             AND p.post_status = 'publish'
             AND p.id = m.post_id
             AND m.meta_key = '_thumbnail_id'
             LIMIT 4
            ) TT
