是否可以通过此查询使用数组?
此版本不起作用:$args=数组(\'顺序\'=>\'ASC\',
>\'meta\\u key=>数组(\'city\\u 1\',\'city\\u 2),
>\'meta\\u value\'=>数组(\'NY\',\'LA\')
)
query\\u posts($args)
---------
此版本有效:
$args=数组(
“order”=>“ASC”,
“meta\\u key=>“city\\u 1”,
“meta\\u value”=>“LA”)
query\\u posts($args)
---------
有人有主意吗
谢谢

Refer to multiple custom field handling in WP_Query:
$args = array(
\'meta_query\' => array(
\'relation\' => \'OR\',
array(
\'key\' => \'city_1\',
\'value\' => array(\'NY\',\'LA\'),
\'compare\' => \'IN\'
),
array(
\'key\' => \'city_2\',
\'value\' => array(\'NY\',\'LA\'),
\'compare\' => \'IN\'
)
)
);
query_posts($args);
