我想获取所有包含meta_value Book,Study,Art的帖子。但是当我在meta_query系统上放置3个数组时,并没有返回任何内容,但是如果我把2个数组放在它的工作中
// this working
$args = array(
'numberposts' => 10,
'post_type' => 'content',
'meta_query' => array(
'relation' => 'OR',
array(
'key' => 'media_type',
'value' => 'Book',
'compare' => 'LIKE'
),
array(
'key' => 'media_type',
'value' => 'Study',
'compare' => 'LIKE'
)
)
);
//this now working
$args = array(
'numberposts' => 10,
'post_type' => 'content',
'meta_query' => array(
'relation' => 'OR',
array(
'key' => 'media_type',
'value' => 'Book',
'compare' => 'LIKE'
),
array(
'key' => 'media_type',
'value' => 'Study',
'compare' => 'LIKE'
),
array(
'key' => 'media_type',
'value' => 'Art',
'compare' => 'LIKE'
)
)
);
答案 0 :(得分:1)
听起来您正在搜索确切的元值,所以您尝试了:
$args = array(
'posts_per_page' => 10,
'post_type' => 'content',
'meta_query' => array(
array(
'key' => 'media_type',
'value' => array( 'Art', 'Book','Study' ),
'compare' => 'IN'
),
),
);
作为您的查询参数?
Sidenote :参数numberposts
有效,但posts_per_page
现在更常用WP_Query()
。
