//save tutor pod 
function save_tutor_pod($tutor_data) 
{ 
    // save new pod record 
    $pod = pods('tutor'); 

    $pod_id = $pod->save($tutor_data); 

    // return false in case of error 
    if (!$pod_id) 
     return false; 

    return $pod_id; 
} 

Answer 1

我發現了一個簡單的方法來做到這一點

$pod_id = save_tutor_pod($user_data); 

foreach ($certificates_ids as $id) { 
    $is_added = add_post_meta($pod_id, 'certificates', $id); 
}
