Sql Wordpress自定义分类搜索

我正在尝试实现搜索，它将查看自定义分类术语。 我有称为“产品”的自定义类型和称为“类型”的自定义分类法。当我使用wordpress标准表单时，除了不在自定义分类术语中搜索之外，它工作得很好

                SELECT DISTINCT(ID) FROM 
                $wpdb->terms AS terms 
                JOIN
                $wpdb->term_taxonomy as termtaxonomy
                JOIN
                $wpdb->term_relationships AS termrelationship
                JOIN
                $wpdb->posts AS posts

                ON terms.term_id = termtaxonomy.term_id &&
                   termrelationship.term_taxonomy_id = termtaxonomy.term_taxonomy_id &&
                   termrelationship.object_id = posts.ID
                WHERE terms.name LIKE '%".$search."%' OR posts.post_title LIKE       '%".$search."%' OR posts.post_content LIKE '%".$search."%' AND posts.post_type='".$_REQUEST['post_type']

所以，我需要的是： 1.通过“m_类型”分类术语进行WP搜索 2.它应该使用术语的“名称”，而不是“slug”

                SELECT DISTINCT(ID) FROM 
                $wpdb->terms AS terms 
                JOIN
                $wpdb->term_taxonomy as termtaxonomy
                JOIN
                $wpdb->term_relationships AS termrelationship
                JOIN
                $wpdb->posts AS posts

                ON terms.term_id = termtaxonomy.term_id &&
                   termrelationship.term_taxonomy_id = termtaxonomy.term_taxonomy_id &&
                   termrelationship.object_id = posts.ID
                WHERE terms.name LIKE '%".$search."%' OR posts.post_title LIKE       '%".$search."%' OR posts.post_content LIKE '%".$search."%' AND posts.post_type='".$_REQUEST['post_type']

我试图包括额外的查询变量，使它至少能看穿“slug”

                SELECT DISTINCT(ID) FROM 
                $wpdb->terms AS terms 
                JOIN
                $wpdb->term_taxonomy as termtaxonomy
                JOIN
                $wpdb->term_relationships AS termrelationship
                JOIN
                $wpdb->posts AS posts

                ON terms.term_id = termtaxonomy.term_id &&
                   termrelationship.term_taxonomy_id = termtaxonomy.term_taxonomy_id &&
                   termrelationship.object_id = posts.ID
                WHERE terms.name LIKE '%".$search."%' OR posts.post_title LIKE       '%".$search."%' OR posts.post_content LIKE '%".$search."%' AND posts.post_type='".$_REQUEST['post_type']

此代码：

$wp_query->query['tax_query'] =  array(
        array(
            'taxonomy' => 'm_type',
            'field' => 'slug',
            'terms' => 'pen'
        )
    );

                SELECT DISTINCT(ID) FROM 
                $wpdb->terms AS terms 
                JOIN
                $wpdb->term_taxonomy as termtaxonomy
                JOIN
                $wpdb->term_relationships AS termrelationship
                JOIN
                $wpdb->posts AS posts

                ON terms.term_id = termtaxonomy.term_id &&
                   termrelationship.term_taxonomy_id = termtaxonomy.term_taxonomy_id &&
                   termrelationship.object_id = posts.ID
                WHERE terms.name LIKE '%".$search."%' OR posts.post_title LIKE       '%".$search."%' OR posts.post_content LIKE '%".$search."%' AND posts.post_type='".$_REQUEST['post_type']

生成以下SQL：

SELECT SQL_CALC_FOUND_ROWS wp_posts.ID FROM wp_posts INNER JOIN wp_term_relationships 
ON (wp_posts.ID = wp_term_relationships.object_id) INNER JOIN wp_postmeta ON 
(wp_posts.ID = wp_postmeta.post_id) WHERE 1=1 AND ( wp_term_relationships.term_taxonomy_id 
IN (163) ) AND (((wp_posts.post_title LIKE '%pen%') OR (wp_posts.post_content LIKE 
'%pen%'))) AND wp_posts.post_type IN ('product') AND (wp_posts.post_status 
= 'publish' OR wp_posts.post_author = 1 AND wp_posts.post_status = 'private') AND
 (wp_postmeta.meta_key = 'max_price' ) GROUP BY wp_posts.ID 
ORDER BY wp_postmeta.meta_value+0 DESC LIMIT 0, 60

                SELECT DISTINCT(ID) FROM 
                $wpdb->terms AS terms 
                JOIN
                $wpdb->term_taxonomy as termtaxonomy
                JOIN
                $wpdb->term_relationships AS termrelationship
                JOIN
                $wpdb->posts AS posts

                ON terms.term_id = termtaxonomy.term_id &&
                   termrelationship.term_taxonomy_id = termtaxonomy.term_taxonomy_id &&
                   termrelationship.object_id = posts.ID
                WHERE terms.name LIKE '%".$search."%' OR posts.post_title LIKE       '%".$search."%' OR posts.post_content LIKE '%".$search."%' AND posts.post_type='".$_REQUEST['post_type']

因此，基本上，它添加了自定义分类法，即通过帖子搜索，这种分类法（*wp_term_relationships.term_taxonomy_id IN（163）*），但实际上从未将分类法术语与查询字符串进行比较

                SELECT DISTINCT(ID) FROM 
                $wpdb->terms AS terms 
                JOIN
                $wpdb->term_taxonomy as termtaxonomy
                JOIN
                $wpdb->term_relationships AS termrelationship
                JOIN
                $wpdb->posts AS posts

                ON terms.term_id = termtaxonomy.term_id &&
                   termrelationship.term_taxonomy_id = termtaxonomy.term_taxonomy_id &&
                   termrelationship.object_id = posts.ID
                WHERE terms.name LIKE '%".$search."%' OR posts.post_title LIKE       '%".$search."%' OR posts.post_content LIKE '%".$search."%' AND posts.post_type='".$_REQUEST['post_type']

也许我都做错了

我使用此sql查询获取基于标题/分类术语/内容搜索的结果，其中$search是搜索参数，$\u REQUEST['post\u type']，我是p

                SELECT DISTINCT(ID) FROM 
                $wpdb->terms AS terms 
                JOIN
                $wpdb->term_taxonomy as termtaxonomy
                JOIN
                $wpdb->term_relationships AS termrelationship
                JOIN
                $wpdb->posts AS posts

                ON terms.term_id = termtaxonomy.term_id &&
                   termrelationship.term_taxonomy_id = termtaxonomy.term_taxonomy_id &&
                   termrelationship.object_id = posts.ID
                WHERE terms.name LIKE '%".$search."%' OR posts.post_title LIKE       '%".$search."%' OR posts.post_content LIKE '%".$search."%' AND posts.post_type='".$_REQUEST['post_type']
