Q: Why there is no helper for the form tag ?
A:

1.5.0 actually introduces Zend_View_Helper_Form. When using Zend_Form with the
default decorators, however, you will not need to use it, as it is called via
the Form decorator.

Q: is it possible to use Zend_Form on the ZF stable version?
A:

At the time of the webinar, the stable version was 1.0.4, which did not include
Zend_Form. As of 17 March 2008, the stable branch is now 1.5, which includes
Zend_Form.

Q: What about Javascript form validation to syncrhonize the Zend_Validate object attached to the element?  Are we on our own?  Or is there an AJAX hook?
A:

Currently, we do not support client-side validation directly with Zend_Form; you
will have to do this on your own.

However, implementing server-side AJAX validation using Zend_Form is fairly
trivial; simply make a request to an action that will validate the form, and
return a payload with either a boolean true or a list of errors.

Q: what about performace - comparing to other framworks
A:

We have not benchmarked Zend_Form at this time. As with any web application, you
should be applying a number of layers of caching to your applications: content
caching, opcode caching, etc. 

Zend_Form itself consists of many classes and objects, so using an opcode cache
will definitely benefit performance.

Q: Is it possible to set a common id prefix for all form elements?
A:

Yes, through the use of array notation. On your form, simply pass a value to the
setElementsBelongTo() accessor, and all values will be returned in that array,
and have that value as their id prefix. So, if you passed the value 'foo', then
all values will be returned as keys of the 'foo' array, and have ids that begin
with 'foo-'.

Q: Zend_Form allows for File input. However, the default enctype is application/x-www-form-urlencoded. Is it intelligent enough to change to multipart/form-data as soon as a file element is attached?
A:

First, the x-www-form-urlencoded enctype is only used for forms that have a
method of 'POST'.

Second, Zend_Form does *not* currently allow for File input; we do not curretly
have a file element as we are waiting for Zend_Upload/Zend_File_Transfer to
mature and be promoted to core. (There is a FormFile view helper, but no
corresponding Zend_Form element.)

You should theoretically be able to pass an 'enctype' attribute to your form to
change the value utilized; I have not tested this, however.

Q: will there be more options available for the processAjax function? now it returns only json
A:

Yes, this is an improvement we've already noted; you can track it on the Zend
Framework issue tracker:

Q: when you want to "group" radiobuttons or checkboxes: do you use display groups and/or array notation?
A:

The Radio element actually allows you to pass an associative array of value =>
label combinations in order to create a group of radio buttons already; the
label for that element will be used as a label for the group.

We also have a MultiCheckbox element that allows you to create a group of
related checkboxes that will be returned as an array of values. Just like the
Radio element, you can pass an associative array of value => label combinations.

Q: is there some way to interact with database (direct and easy filling using database, foreign keys,... - a kind of CRUD application)
A:

Not yet. :-)

Q: seems that you can always use e.g. createElement, do we need addElement - what is the philosophy behind the difference
A:

addElement() implements a fluent interface, meaning it returns the current
object -- the form object. This allows you to chain together several calls to
addElement() -- or chain such calls with other accessors and factories in the
Zend_Form class.

createElement() is used to create an element using the current form object's
settings -- such as plugin paths -- and returns that element; however, the
element is *not* attached to the form at that point.

Yzmir Ramirez - 10:06 am
Q: Any idea if native AJAX support will be implemented to use our validator class for the element prior to being able to submit the form?
A:

Possibly in a future release. If we do so, it will be specific to only one or
two libraries, as we do not wish to maintain a javascript code base within Zend
Framework.

Aldemar Bernal - 10:07 am
Q: Is it better to have an extended class by form or to add methods to the models classes e.g user::getUserLoginForm()
A:

It really depends on your needs. I will often use both -- e.g., have the model
have an accessor to retrieve the form, but in that accessor instantiate a
concrete, custom form class.

Q: Is Zend Framework ever going to have a merchant service module, like Zend_Paypal, or Zend_Payment or something like it?
A:

If Zend Framework contributors have a need for such components, then yes. If
you'd like to contribute such a component, please read our contributor
