Hi,

I need to create a form with dependant selects. The number of selects that
will be shown are not always the same, because not all the levels have
items. I mean, one item can have 3 levels below, and another item in the
same level has 5 levels below.

So, I was thinking in creating a form class, but since the number of fields
is dynamic, how should be that form class?

sf 1.4

I have dealing with that a couple of time before, I have use two ways (I
don´t know if they are the best).
The first, I know all I need, before request the form, for example based in
the user credential. In that case I made the changes at
"lib/form/doctrine/your-form.php"
public function configure()
{
     //Some condition here example
     $user = sfContext::getInstance()->getUser(); //the autenticated user

     if (!$usuario->hasCredential('admin') or
!$usuario->hasCredential('Nacional') or
!$usuario->getGuardUser()->getIsSuperAdmin()):
     {
          $arrAreasId = array(0); $arrAreasNombres = array("Seleccione un
área");
          //some code here to fill the $arrAreasId and $arrAreasNombres
arrays, the example is to big

          //Some configuration here. example
          $this->widgetSchema['Area'] = new
sfWidgetFormChoice(array('choices'=>array_combine($arrAreasId,
$arrAreasNombres),'expanded'=>false)); //I changed the control from a
textbox to a selectbox with my own content
          //Or hide some fields
          unset(  $this['created_at'], $this['updated_at'],
$this['cal_rang_edad']
    );
     }

The second way: when I make the page request I still don´t know the
condition yet or I know just in this moment what I need (the conditional)
In this case in your form at:
apps/frontend/modules/mymodule/templates/_form.php

<form action="<?php echo url_for('personal/'.($form->getObject()->isNew() ?
'create' : 'update').(!$form->getObject()->isNew() ?
'?id='.$form->getObject()->getId() : '')) ?>" method="post" <?php
$form->isMultipart() and print 'enctype="multipart/form-data" ' ?>>
<?php if (!$form->getObject()->isNew()): ?>
<input type="hidden" name="sf_method" value="put" />
<?php endif; ?>
// some required field here. example
<?php echo $form->renderHiddenFields() ?>
<table>
<?php echo $form['id']->renderRow() //also a required field?>
//some conditional here. example
<?
if($condition==1){
    echo $form['field1']->renderRow()

   echo $form['field2']->renderRow()
)?>
<table>
</form>

*Suppose  the $condition var was defined in the accion.class.php file of
that module, example
  public function executeNew(sfWebRequest $request)
  {
    $this->form = new dptoForm();
    $condition = 1; // define your condition here. Make the steps you need
to get it.
  }

and
  public function executeEdit(sfWebRequest $request)
  {
    $this->forward404Unless($dpto =
Doctrine_Core::getTable('dpto')->find(array($request->getParameter('id'))),
sprintf('Object dpto does not exist (%s).', $request->getParameter('id')));
    $this->form = new dptoForm($dpto);
    $condition = 0; // define your condition here . Make the steps you need
to get it.
  }

I hope this help.
Excuse my english please
