naming forms in PHP

[eluser]agubski[/eluser]
Guys,

I have borrowed following piece of code to call in JS module

<form name="testform">

<!-- calendar attaches to existing form element -->
<input type="text" name="testinput" />
[removed]
new tcal ({
// form name
'formname': 'testform',
// input name
'controlname': 'testinput'
});

[removed]
</form>

my form is called via - <?=form_open('place_add/insert_data');?>

Any idea how I can introduce a form name?

Thanks
