Zend_Form display forms from DB table rows - zend-framework

Question

I'd like to build a dynamic FORM according to DB Table records.
It'a room reservation module.
Hotel has several room types with descriptions.
When booking a hotel user should see form like:
-- firstname [text-input]
-- lastname [text-input]
-- check-in [text-input and datepicker]
-- check-out [text-input and datepicker]
-- Room1 Title:Room Description [Text-input form for number of rooms]
-- Room2 Title:Room Description [Text-input form for number of rooms]
-- Room3 Title:Room Description [Text-input form for number of rooms]
-- Room4 Title:Room Description [Text-input form for number of rooms]
I have this Room records in a table.
How can I build this with ZEND_FORM?
I think it should be smth like foreach of objects of rooms
I also would like to add auto calculations.
Each room has specific price per night.
I want to sum-up number of rooms and multiply by number of nights.
So how can I accomplish it using Zend_Form?
Should I add some helpers? new type of text element?
If yes, please provide some sources to guide's and How To's with examples.
Thank you in advance.

Answer 1

I had something similar but with checkboxes, this is an adaptation, I hope it helps.
class Form_Booking extends Zend_Form {
function init()
{
$this->addElement('text', 'first_name', array (
'label' => 'First name',
'required' => true
));
// ... all the other fields
$count = 1000; // I used this value because I had a strange bug
//$rooms = array() the entries from your table
foreach ($rooms as $one)
{
$this->addElement('checkbox', "$count", array (
'label' => $one['room_title'],
'description' => $one['room_description'],
'belongsTo' => 'rooms',
));
$count++;
}
}
}
