Hello everyone,
I am having some trouble with embedded forms and removal of these. I
have a form that represents an image. Many images can belong to an
image group. I have created a form that embeds many image forms into
one image group form.
Each embedded image form has a checkbox widget, so when checked, it is
processed for deletion by the form.
The form allows for a new image to be uploaded to the group, again
through an embedded form.
My problem is, that during the transaction, the image to be deleted is
deleted, but immediately after, I am seeing a blank insert statement
being run. If I delete the line that calls Doctrine_Core::...delete(),
the problem goes away. Can anyone see where I am going wrong?
Thanks all,
Richard
Code is below:
--
Image Group Form:
--
class ImageCollectionGroupForm extends ImageGroupForm {
protected $scheduleForDeletion;
public function configure() {
if (!$businessAccount = $this->getOption('business_account'))
{
throw new InvalidArgumentException('You must provide a
business account object.');
}
parent::configure();
$this->useFields(
array(
'name',
'description'
)
);
$image = new Image();
$image->ImageGroup = $this->getObject();
$newImage = new ImageForm($image, array('business_account' =>
$businessAccount));
$this->embedForm('newImage', $newImage);
$currentImages = new ImageCollectionForm(array(),
array('image_group' => $this->getObject(), 'business_account' => $this-
>getOption('business_account')));
$this->embedForm('currentImages', $currentImages);
}
public function doBind(array $values) {
foreach ($values['currentImages'] as $i => $image) {
if (isset($image['delete'])) {
$this->scheduleForDeletion[$i] = $image['id'];
}
}
parent::doBind($values);
}
protected function doUpdateObject($values) {
if (count($this->scheduleForDeletion)) {
foreach ($this->scheduleForDeletion as $index => $id) {
unset($values['currentImages'][$index]);
unset($this->embeddedForms['currentImages'][$index]);
unset($this->validatorSchema['currentImages']
[$index]);
Doctrine_Core::getTable('Image')->findOneById($id)-
>delete();
}
}
parent::doUpdateObject($values);
}
public function saveEmbeddedForms($con = null, $forms = null) {
if (null === $forms) {
$newImage = $this->getValue('newImage');
$forms = $this->embeddedForms;
foreach ($this->embeddedForms['newImage'] as $name =>
$form) {
if (!isset($newImage[$name]) ||
empty($newImage[$name])) {
unset($forms['newImage'][$name]);
}
}
if (!count($forms['newImage'])) {
unset($forms['newImage']);
}
}
return parent::saveEmbeddedForms($con, $forms);
}
}

Image Form:

class ImageCollectionForm extends sfForm {
public function configure() {
if (!$imageGroup = $this->getOption('image_group')) {
throw new InvalidArgumentException('You must provide an
image group object.');
}
$imageGroup = $this->getOption('image_group');
foreach ($imageGroup->getImages() as $i => $image) {
$form = new ImageForm($image, array('business_account' =>
$this->getOption('business_account')));
$this->embedForm($i, $form);
}
}
}
