Question

我使用以下查询来获取tittle，data，tagss内容，slug，父ID。这工作正常，但我需要获得与wp_postmeta表有关系的图像和图像源，所以我在第一个查询的while循环中使用了第二个查询

首先查询： - 选择wp_posts.ID为Id，wp_posts.post_title为标题，wp_posts.post_date为DATE，

  GROUP_CONCAT(wp_terms.name) AS TAGS, wp_posts.post_content as CONTENT,wp_terms.term_id,wp_terms.slug,wp_posts.post_parent as parent_id FROM wp_terms

  INNER JOIN wp_term_taxonomy ON wp_terms.term_id  = wp_term_taxonomy.term_id

  INNER JOIN wp_term_relationships ON wp_term_taxonomy.term_taxonomy_id = wp_term_relationships.term_taxonomy_id

  INNER JOIN wp_posts ON wp_posts.ID = wp_term_relationships.object_id

  WHERE post_type LIKE 'post' AND post_status LIKE 'publish' AND wp_terms.slug in ('interview','variety','lastpage','sport','arab-global','opinion','business','uae','firstpage')  

GROUP BY wp_posts.ID order by post_date limit 150

和sencond查询为

select select wp_postmeta.meta_value from wp_postmeta left join wp_posts on wp_postmeta.post_id in ('".$row['Id']."') = wp_posts.id in ('".$row['Id']."') and meta_key='_wp_attached_file'"

但是我没有得到任何细节，所以我将关系与wp_post表的parent_id作为第三个查询而不是第二个查询。

select select wp_postmeta.meta_value from wp_postmeta left join wp_posts on wp_postmeta.post_id in ('".$row['parent_id']."') = wp_posts.id in ('".$row['parent_id']."') and meta_key='_wp_attached_file'"

之后，我使用单个查询来获取所有记录，如下所示

SELECT wp_posts.ID as Id,wp_posts.post_title as Title,wp_posts.post_date as DATE,wp_postmeta.meta_key,wp_postmeta.meta_value,
GROUP_CONCAT(wp_terms.name) AS TAGS, wp_posts.post_content as CONTENT,wp_terms.term_id,wp_terms.slug,wp_posts.post_parent as parent_id FROM wp_terms
INNER JOIN wp_term_taxonomy ON wp_terms.term_id  = wp_term_taxonomy.term_id
INNER JOIN wp_term_relationships ON wp_term_taxonomy.term_taxonomy_id = wp_term_relationships.term_taxonomy_id
INNER JOIN wp_posts ON wp_posts.ID = wp_term_relationships.object_id
INNER JOIN wp_postmeta ON(wp_posts.ID = wp_postmeta.post_id)
WHERE post_type LIKE 'post' AND post_status LIKE 'publish'
GROUP BY wp_posts.ID order by post_date limit 150

但是在那个查询中我有多个meta_key和多个元值，有任何有用的解决方案，所以我可以通过简单的sql和php获取wp_post详细信息及其源和图像

Answer 1

试试这个

$ meta_value_id =＆＃34;从wp_postmeta中选择meta_value，其中meta_key =＆＃39; _thumbnail_id＆＃39;和post_id =＆＃39;＆＃34;。$ row [＆＃39; Id＆＃39;]。＆＃34;＆＃39;＆＃34 ;;
$ query_run_meta = mysql_query（$ meta_value_id）; $ row1 = mysql_fetch_assoc（$ query_run_meta）;

            $meta_image=  "select meta_value from wp_postmeta where meta_key='_wp_attached_file' and post_id='".$row1['meta_value']."'";   
            $query_meta=  mysql_query($meta_image);
            $row2=  mysql_fetch_assoc($query_meta);

现在您可以从$ row2获取图像源。

Answer 2

从上面的查询中您获得了帖子ID，您可以使用以下函数来获取帖子图片网址：

$post_thumbnail_id = get_post_thumbnail_id( $post_id ); //It will return id of attached thumbnail
 $post_image_src= wp_get_attachment_image_src(post_thumbnail_id);// This will return source url of thumbnail

如何使用源和图像获取wp_posts详细信息
