我想按2个自定义字段和字母排序，这是我的代码

\'meta_query\'    => array(
    array(
        \'relation\' => \'AND\',
        \'awards\' => array(
            \'key\'       => \'awards\',
            \'compare\'   => \'EXISTS\',
        ),
        \'points\' => array(
            \'key\'       => \'points\',
            \'compare\'   => \'EXISTS\',
        ),
    ),
),
\'orderby\' => array(

    \'awards\'       => \'desc\',
    \'points\'     => \'desc\',
),

因此，如果奖励相同，则按分数排序，但如果分数相同，则按字母顺序排序。

\'meta_query\' => array(
    \'relation\' => \'AND\',
    \'awards_clause\'   => array( // clause
        \'key\'     => \'awards\',
        \'compare\' => \'EXISTS\',
    ),
    \'points_clause\'   => array( // clause
        \'key\'     => \'points\',
        \'compare\' => \'EXISTS\',
    ),
),
\'orderby\'    => array(
    \'awards_clause\' => \'DESC\',
    \'points_clause\' => \'DESC\',
),
