I have gone through the <http://www.yiiframework.com/doc/guide/1.1/en/form.table>

I did not understand what this means:

```
$items=$this->getItemsToUpdate();

```

what is this `$this->getItemsToUpdate()` function?

I am trying to insert dynamic rows at a time. I have used jquery for creating the data but I don't know how to insert them into the database.
