WordPress要如何实现多个自定义字段排序？

WordPress查询语句中的“orderby”本身就支持多条件排序，根据你所说的先按pingjunzhi降序排序，再按zongfen降序排序，那么对应的查询语句如下：

$args = array(

'posts_per_page' => 6,

'ignore_sticky_posts' => 1,

'meta_query' => array(

'relation' => 'AND',

'pingjunzhi_clause' => array(

'key' => 'pingjunzhi',

'type' => 'NUMERIC',

'compare' => 'EXISTS',

),

'zongfen_clause' => array(

'key' => 'zongfen',

'type' => 'NUMERIC',

'compare' => 'EXISTS',

),

),

'orderby' => array(

'pingjunzhi_clause' => 'DESC',

'zongfen_clause' => 'DESC',

),

);
