What is the exact meta_key and meta_value for the field I created
using the function custom_user_profile_fields ?
created_by
and some user ID, for example:
$args = array(
'meta_key' => 'created_by',
'meta_value' => 123,
)
You could use a meta_query
for more complex searches.
$args = array(
'meta_query' => array(
array(
'key' => 'created_by',
'compare' => 'EXISTS',
),
)
);
var_dump(get_users($args));
Essentially, though, what you are doing is correct.
