How to order translated with not translated fields using doctrine knp translatable extentions with A2lix translation form?

问题

I'm searching for a simple way to edit translated fields within a symfony2 form. I'm using the doctrine knp translatable extentions for translation of the entity. The form mixes not translated with translated properties in a special order. The form should be displayed (end edit) only in the active language. For example:

 $builder
 ->add('key')
 ->add('translate1','text',array(
    'property_path' => 'translations[de].translate1',
 ))
 ->add('mynumber')
 ->add('translate2','text',array(
    'property_path' => 'translations[de].translate2',
))

If the language translations[de] does not exists i get an error: "Cannot read property "translate1" from an array... "

A2LiX Translation Form is not the solution, because it displays all translatabe fields in a single list.

Any ideas?

If you need to display the form fields in a specific order (using A2lix) you can do it like in this example:

$builder
     ->add('key')
     ->add('mynumber')
     ->add('translations', 'a2lix_translations', [
         'required_locales' => ['de'], <-- your current locale
             'fields'           => [
                 'translate1' => [
                     # your field options
                 ],
                 'translate2' => [
                     # your field options
                 ],
    ))

Then in the view:

{% import "A2lixTranslationFormBundle::macros.html.twig" as a2lixTranslations %}

{{ form_errors(form_edit) }}
{{ form_start(form_edit) }}
{{ form_row(form_edit.key) }}    
{{ a2lixTranslations.partialTranslations(form_edit.translations, ['translate1']) }}
{{ form_row(form_edit.mynumber) }}
{{ a2lixTranslations.partialTranslations(form_edit.translations, ['translate2']) }}
{{ form_end(form_edit) }}

Actually i solved my problem with a custom from type with two event listeners for setting and getting translations values:

  /**
 * build fields
 * @param \Symfony\Component\Form\FormBuilderInterface $builder
 * @param array $options
 */
public function buildForm(FormBuilderInterface $builder, array $options)
{

    /**
     * merge new translation
     */ 

    $builder->addEventListener(FormEvents::SUBMIT, function(FormEvent $event) use ($options) {

        //test
        $form = $event->getForm();//form
        $data = $event->getData();//products

        $newTranslation = $event->getData();

        $key=$options['translation_property'];

        $lang=$this->getLocale($options);

        $entity=$form->getParent()->getData();

        $setter='set'.strtoupper($key);
        $getter='get'.strtoupper($key);

        $entity->translate($lang)->$setter($newTranslation);
        $entity->mergeNewTranslations();
     });

    /**
     * Populate with data
     */ 
    $builder->addEventListener(FormEvents::PRE_SET_DATA, function(FormEvent $event) use ($options) {

        $data = $event->getData();//products
        $form = $event->getForm();//form

        $key=$options['translation_property'];
        $lang=$this->getLocale($options);

        $entity=$form->getParent()->getData();

        $setter='set'.strtoupper($key);
        $getter='get'.strtoupper($key);

        $oldValue=$entity->translate($lang,false)->$getter();//no fallback

        $event->setData($oldValue);

    });
}

The fields are not mapped. translation property name and language can be provided directly.

 /**
 * Defauls
 * @param \Symfony\Component\OptionsResolver\OptionsResolverInterface $resolver
 */
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
    $resolver->setDefaults(array(
        'translation_path'=>'translations',
        'translation_property' => null,
        'translation_lang'=>null,//getLocale or set in form type
        'mapped'=>false     
    ));
}

And type inherit form basic text.

public function getParent()
{
    return 'text';
}

After define it as a twig extension service (translation_text) you can use it quite easy:

 $builder
        ->add('name')           
        ->add('key')            
        ->add('translate1', 'translation_text',
            array(
                    'translation_property'=>'translate1',
                    'translation_lang'=>null
            ))
