HOw to submit data with Custom assest at backend

At last i made my own assest and extended it from Standard page.[quote]<contents>
<section name="Contents">

<field>

<function_call>

<paint_function name="check()" />

<process_function name="redirectToBodycopy" />

</function_call>

</field>

</section>

</contents>[/quote] This was my edit_interface_details file and my check function is displaying the dtata in tabular form with about 20 rows. Now i want that if user click on any row then i open a light box where user can edit that data. I can do that but problem is how should i insert the data in database. i mean if i make function to save data in data base , then which adrress i have to use in form's action attribute so that when user click on submit them my data enters in database.

If you use:


    $this->getURL()


That will return the URL for the current page, I would just use this as the form action.
