示例1: saveOrUpdate
/**
* Saves this entity if its a brand new instance that does not exist
* in the database; otherwise updates this entity in the database by
* flushing all its attributes directly to the database.
*/
public function saveOrUpdate()
{
try {
// if this entity has been destroyed then we cannot
// assert the validaty of this instance identity
// so we simply ignore any persistence operations.
if ($this->isDestroyed() == true) {
return;
}
// avoid getting fields array directly, in case a
// sub-class of this object overrides the default
// behavior for listing this objects fields.
$fields = $this->getAttributes();
if ($this->id) {
// since this is an update operation we
// update the modification timestamps.
if (array_key_exists('modified', $fields)) {
$this->modified = $this->getDate();
}
if (array_key_exists('modifiedid', $fields)) {
$this->modifiedid = time();
