如何在 WordPress 中获取最新被评论的文章列表

： add_filter('posts_clauses', function ($clauses, $wp_query){ global $wpdb; $orderby = $wp_query->...: 'DESC'; if($orderby == 'comment_date'){ $clauses['fields'] .= ', ct.comment_post_ID, MAX(ct.comment_ID...AND ct.comment_parent=0 AND ct.comment_approved NOT IN ('spam', 'trash', 'post-trashed')"; $clauses...['groupby'] = "ct.comment_post_ID"; $clauses['orderby'] = "cid {$order}"; } return $clauses; },...10, 2); 上面的代码简单解释一下，就是通过 posts_clauses 接口实现文章表和评论表连表，然后通过评论时间进行排序获取最新被评论的文章列表。

WordPress 技巧：后台文章列表搜索支持 ID

在进行 debug 的时候，对方告诉你 ID 的时候，在文章列表是无法快速定位到对应的文章的，可以通过下面的代码让 WordPress 在后台文章列表搜索支持 ID： add_filter('posts_clauses...', function ($clauses, $wp_query){ if($wp_query->is_main_query() && $wp_query->is_search()){ global...$wpdb; $search_term = $wp_query->query['s']; if(is_numeric($search_term)){ $clauses['where'...)){ $clauses['where'] = str_replace('('....$wpdb->posts.'.post_title LIKE', $clauses['where']); } } return $clauses; }, 2, 2); 上面代码支持直接搜索一个文章

Elasticsearch Span Query跨度查询

查询主要由两部分组成，一部分是嵌套的子span查询，另一部分就是他们之间的最大的跨度 { "span_near" : { "clauses" : [ {...，value1，value2，value3最长的跨度不能超过12. span_or查询这个查询会嵌套一些子查询，子查询之间的逻辑关系为或 { "span_or" : { "clauses...{ "field1" : "hoya" } }, "exclude" : { "span_near" : { "clauses...span_term" : { "field1" : "foo" } }, "big" : { "span_near" : { "clauses
