Hi everyone. I want to create a module for Categories. Every category
has 1 or more images. The i18n fields are: title and description.
Basically, I have in CategoriesForm.class.php (I won't put the exact
script, but the essencial things just to show you my point. It would
be too long if I put the complete script):
<?php
class CategoryForm extends BaseCategoryForm
{
public function configure()
{
$this->embedI18n( array( 'en', 'es' ) );
$imagesCollectionForm = new ImagesCollectionForm( $this-
>getObject() );
$this->embedForm( 'imagesCollection',
$imagesCollectionForm );
$this->embedRelation( 'Images' );
}
public function saveEmbeddedForms( $con = null, $forms =
null )
{
if ( $forms === null )
{
$images = $this->getValue( 'imagesCollection' );
$forms = $this->embeddedForms;
foreach ( $forms[ 'imagesCollection' ] as $name =>
$form )
{
if ( !isset( $images[ $name ] ) )
{
unset( $forms[ 'imagesCollection' ]
[ $name ] );
}
}
}
return parent::saveEmbeddedForms( $con, $forms );
}
}
?>
Ok, suppose that the model "Category" are related to the model
"Image". Then I create a "ImagesCollectionForm" that, basically, embed
to itself two "ImageForm" (just like it's explained in the book "More
with Symfony":
http://www.symfony-project.org/more-with-symfony/1_4/en/06-Advanced-Forms
In this way the form appears correctly. I did everything just like the
book says (except for the i18n part that I had to add myself).
>From here, my questions:
1) Is this the better way to do it for i18n forms?
2) I'm having trouble with thumbnail generation and deleting the
images when I update or delete them. How would I, for example, create
two thumbnails from each added or modified Image? I thought on putting
the generation code on the "Image" model, overriding the "save"
function. Could it be like this?
public function save( Doctrine_Connection $con = null )
{
// .. more functions.. generateThumbnails()... deleteImages()..
etc
// if getLink() returns '' it means that an image needs to be
added
if ( $this->getLink() !== '' )
{
if ( !$this->isNew() )
{
$this->deleteImages();
}
$this->generateThumbnails();
}
parent::save( $con );
}
$this->getLink() in this case represents the value that it's submitted
with the form or the "link" field that's actually in the DB (if the
object is being modified)?
If my questions are a little tricky, please, could you tell me the
steps to create a form with i18n behavior and adding to it an
imagesCollection form in the correct way? which functions would I need
to override and in which classes? I red every book of Symfony but
there's some little things that I still don't know exactly how they
work. If you could give me some steps to do it and a brief explanation
of why it has to be in that way.. it would be incredibly useful for
me.
Thanks in advance.
