我解决这个问题如下。我们应该比较每个元值,而不是在元值中传递数组。
Array(
[post_type] => post
[posts_per_page] => 3
[order] => DESC
[meta_query] => Array(
[relation] => AND
[0] => Array(
[key] => argomento
[value] => Array([0] => 2875 )
[compare] => like
)
[1] => Array(
[key] => argomento
[value] => Array([0] => 2884 )
[compare] => like
)
[2] => Array(
[key] => argomento
[value] => Array([0] => 2877 )
[compare] => like
)
[3] => Array(
[key] => geo
[value] => Array([0] => 2853 )
[compare] => LIKE
)
)
)
谢谢
