这是我的代码：
$type = "pictures";
$args[\'orderby\'] = "post_modified";
$args[\'order\'] = "DESC";
$args[\'post_type\'] = $type;
$args[\'post_status\'] = "publish";
$args[\'meta_query\'] = array(
array (
\'key\' => \'picture_liked_users\',
\'value\' => array(get_user_meta($user->ID, \'following_users\', true)),
\'compare\' => \'LIKE\'
),
);
我需要获得我关注的用户喜欢的图片。
以下是如何将以下\\u users meta存储在数据库中的示例：
a:1:{i:0;s:2:"87";}
因此，我试图通过使用数组来获取用户meta following\\u user，但失败了。这给了我一个PHP错误，并且尝试提取PHP函数，但也失败了。
有人能帮我吗？

对于您正在寻找的内容来说，这应该更好，唯一的问题可能是如何将meta作为实际数组或需要转换为数组的字符串返回。
$args = array(
\'post_type\' => \'pictures\',
\'orderby\' => \'post_modified\',
\'order\' => \'DESC\'
// post_status is unnecessary because default is \'publish\'
);
$following_users = get_user_meta($user->ID, \'following_users\', true);
if ( !empty( $following_users ) ) {
$meta_query = array();
foreach ( $following_users as $following_user ) {
$meta_query[] = array(
\'key\' => \'picture_liked_users\',
\'value\' => $following_user,
\'compare\' => \'LIKE\'
);
}
// If our count is 2+, we need to set our relation
if ( count( $meta_query ) > 1 ) {
$meta_query[\'relation\'] = \'OR\';
}
// Only set our meta_query if there is anything to set
if ( !empty( $meta_query ) ) {
$args[\'meta_query\'] = $meta_query;
}
}
