Overview
A WordPress question. Thanks for your consideration.
Isn't it possible to specify array_column information in meta_query key specification?
Learn moreThe article has a custom field called premium_users.
The contents are the following array.
$premium_users = get_post_meta ($post_id, 'premium_users');
/ *
Here's what $premium_users looks like
[
['user_id' =>1, 'age' =>10],
['user_id' =>2, 'age' =>20]
]
*/
I would like to use this information in a meta_query search as shown below.
While the specified value in meta_query is a user ID as shown below, the target array was stumbled with information called age as shown above.
How can I specify meta_query in such cases?
'meta_query' = array (
array (
'value' =>get_current_user_id () // I want to specify by user ID
, 'key' =>'premium_users', // but here is age
, 'type' =>'NUMERIC'
, 'compare' =>'LIKE'
),
);

If you are using a custom field plug-in
It might be JSON, not serialized
user_id value type may be string instead of int
Check it by looking in the DB post_meta table
