Delete embed forms/objects in Symfony

First of all, you have to add a delete checkbox to the embedded form:

// lib/form/doctrine/ formclass -> configure()
if ($this->object->exists())
{
   $this->widgetSchema['delete'] = new sfWidgetFormInputCheckbox();
   $this->validatorSchema['delete'] = new sfValidatorPass();
}

Don't forget to echo the 'delete' form widget in the template. Now open the form class which embed the other form. You have to overwrite some basic methods. The code below is used and created by me, but perhaps you won't be able to use/understand. Please, first check the the following blog entry: Embedding Relations in Forms with Symfony 1.3 and Doctrine

public function saveEmbeddedForms($con = null, $forms = null)
 {
  if (null === $forms)
  {
   $notes = $this->getValue('newNotes');
   $forms = $this->embeddedForms;
   foreach ($this->embeddedForms['newNotes'] as $name => $form)
   {
    if (!isset($notes[$name]))
    {
     unset($forms['newNotes'][$name]);
    }
   }
  }
  
  foreach ($forms as $form)
  {
    if ($form instanceof sfFormObject)
    {
   if (!in_array($form->getObject()->getId(), $this->scheduledForDeletion))
   {
     $form->saveEmbeddedForms($con);
     $form->getObject()->save($con);
   }
    }
    else
    {
   $this->saveEmbeddedForms($con, $form->getEmbeddedForms());
    }
  }


 }
 
  protected function doBind(array $values)
  {   
    if (isset($values['Notes']))
    {
      foreach ($values['Notes'] as $i => $noteValues)
      {
        if (isset($noteValues['delete']) && $noteValues['id'])
        {
          $this->scheduledForDeletion[$i] = $noteValues['id'];
        }
      }
    }
    
    parent::doBind($values);
  }
  
  protected function doUpdateObject($values)
  {
    if (count($this->scheduledForDeletion))
    {
      foreach ($this->scheduledForDeletion as $index => $id)
      {
        unset($values['Notes'][$index]);
        unset($this->object['Notes'][$index]);
        Doctrine::getTable('ServiceNote')->find($id)->delete();
      }
    }
 
    $this->getObject()->fromArray($values);
  }
