require_once DOL_DOCUMENT_ROOT.'/core/class/extrafields.class.php';

Load extrafield array in object :

$extrafields = new ExtraFields($db);
$extralabels=$extrafields->fetch_name_optionals_label('''ObjectClassName''');

Load extrafield into object :

''$object''->fetch($rowid);
''$object''->fetch_optionals($rowid,$extralabels);

Before call $object->create or $object->update :

$ret = $extrafields->setOptionalsFromPost($extralabels,''$object'');

Inside edit page to display extrafields :

$reshook=$hookmanager->executeHooks('formObjectOptions',$parameters,$act,$action);    // Note that $action and $object may have been modified by hook
if (empty($reshook) && ! empty($extrafields->attribute_label))
{
      print ''$object''->showOptionals($extrafields,'edit');
}

Inside view page to display extrafields :

$reshook=$hookmanager->executeHooks('formObjectOptions',$parameters,$act,$action);    // Note that $action and $object may have been modified by hook
if (empty($reshook) && ! empty($extrafields->attribute_label))
{
      print ''$object''->showOptionals($extrafields);
