Hi!

What i like to know is: How is it possible to create custom forms?
I like to display a custom form, but it seems that the form attributes wouldn't be parsed...

So, here is my setup:
1. I have my custom Page (KMForm_Page) / PageController (KMFormPage_Controller)
The Controller looks like this:
class KMFormPage_Controller extends Page_Controller
{
function KMForm()
{
return new KMForm($this,'KMForm');

}

}

2. I do of course have a custom Form (KMForm) as used above:
class KMForm extends Form
{
function __construct($controller, $name)
{
$fields = new FieldSet(
new EmailField('email', 'E-Mail-Adresse'),
new TextField('telefon', 'Telefonnummer')
);

$actions = new FieldSet(
new FormAction('submit', 'Absenden')
);

$requiredFields = new RequiredFields('email');

parent::__construct($controller, $name, $fields, $actions, $requiredFields);
}

function forTemplate()
{
// Erwartet Template mit Namen 'KMForm'
return $this->renderWith(array(
$this->class,
'Form'
));
}

function submit($data, $form)
{
print_r($data);
}
}

3. I have a appropriate Template KMForm.ss:
<form $FormAttributes>
<% if Message %>
<p id="{$FormName}_error" class="message $MessageType">$Message</p>
<% else %>
<p id="{$FormName}_error" class="message $MessageType" style="display: none;"></p>
<% end_if %>

<fieldset>
<div id="email" class="field email">
<label for="$Form_email">E-Mail-Adresse</label>
$dataFieldByName(email)
</div>
<div id="telefonnummer" class="field telefon">
<label for="$FormName_telefon">Telefonnummer</label>
$dataFieldByName(telefon)
</div>
$dataFieldByName(SecurityID)
</fieldset>

<% if Actions %>
<div class="Actions">
<% control Actions %>
$Field
<% end_control %>
</div>
<% end_if %>

</form>

Site displays, but:
- The Rendering of the Variables $FormAttributes, $FormName, $Form_email etc. doesn't happen at all
- site displays only the non-dynamic items of KMForm.ss

So, as usual the failure sits in front of the PC...
Any hints, what i'm doing wrong?

Thanks for your time!

Not 100% sure, however you may try following two points:
1. make sure KMForm.ss is in 'templates/Includes' directory.
2. it seems that you form function and form class has the same name, what I did recently is given the form subclass a different name. ie MyForm extends Form, then in your page controller, do

function MyFirstForm(){
      return new MyForm($this, 'MyFirstForm');
   }

In your case, maybe it is better to change sub class name, because you need KMForm.ss match the function name.

Hope it will help

I was having similar issues. Check this forum post. It was my answer:
