I need help for custom file field api.

I create custom file field in Administer -> Customize Data and Screens -> Custom Fields, Field id is 6, => name is custom_6.
I assign this field into register profile for event, When user select and submit the file to server, i save upload it and save to database such as :
<code>
function registration_save_file($file_params){
      if (!civicrm_initialize()) {
         return null;
      }
         $file_params = array(
            'version'       =>3,          
            'file_type_id'  => $file_type_id,
            'mime_type'   => $file_params['type'],
            'name'      => $file_params['name'],
            'uri'         => $file_params['name'],
            'upload_date'   => date('Y-m-d h:i:s', time()),
         );
         $file_save = civicrm_api('File','Create', $file_params);         
         return $file_save;
}
</code>
The next i Save file id to contact info by :
<code>
function registration_save_contact($val){
      $params= array(
         'contact_type'  => 'Individual',   
         'preferred_language' => 'en_US',
         'version' =>3,
         'last_name'  => $val["last_name"],
         'first_name'  => $val["first_name"],
      );
      $upload = civicrm_registration_save_file($file);
      if (!civicrm_error ( $upload)) {
         $params['custom_6'] = $upload["id"];
      }
      if (!civicrm_initialize()) {
         return null;
      }      
      $contact = civicrm_api('Contact','Create', $params);
      if(civicrm_error($contact)){
         drupal_set_message(t($contact['error_message']), 'error');   
      }else{
         return $contact;
      }
}
</code>
OR
<code>
   if (!civicrm_initialize()) {
      return null;
   }
   
   
   $contactID = 17876;
   $params_contact = array(
         'version'       =>3,
         'id'           => $contactID,
         'custom_6'   => $upload["id"]//$upload["id"] = 30
   );
   
   $update = civicrm_api( 'Contact', 'Update', $params_contact);

   if (!civicrm_error ($update)) {
        // error handling
        var_dump($update);

    }
</code>
Or i using such as:
<code>
$contactID = 17820;
$passort = civicrm_api( 'CustomValue', 'Create', array(
      'version'       =>   '3',
      'entity_id'      =>   $contactID,
      $columnName      =>   $upload["id"]//$upload["id"] = 30,
      )   
   );
   var_dump($passort);
   // it return array(2) { ["is_error"]=> int(1) ["error_message"]=> string(57) "A fatal error was triggered: Cannot recognize File for 30" }
</code>

How to using API to save value for custom file field?

I would take the message literally first? So is your custom upload directory set correctly (in the CiviCRM system settings), do you have enough access to the directory to be able to create the file there?
Is there a reason why you do not want to use REST with the API? I am not sure why you are using the upload file, but that can be me :-)
