我正在寻找一种在symfony2表单中编辑翻译字段的简单方法。我正在使用doctrine knp translatable extentions来翻译实体。表单混合未按特殊顺序翻译为已翻译的属性。应仅以活动语言显示表单(结束编辑)。例如:
$builder
->add('key')
->add('translate1','text',array(
'property_path' => 'translations[de].translate1',
))
->add('mynumber')
->add('translate2','text',array(
'property_path' => 'translations[de].translate2',
))
如果语言翻译[de]不存在,我会收到错误:“无法从数组中读取属性”translate1“......”
A2LiX翻译表不是解决方案,因为它在单个列表中显示所有translatabe字段。
有什么想法吗?

如果您需要按特定顺序显示表单字段(使用A2lix),您可以像在此示例中那样执行:
$builder
->add('key')
->add('mynumber')
->add('translations', 'a2lix_translations', [
'required_locales' => ['de'], <-- your current locale
'fields' => [
'translate1' => [
# your field options
],
'translate2' => [
# your field options
],
))
然后在视图中:
{% 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) }}

实际上我用自定义类型解决了我的问题,其中有两个事件监听器用于设置和获取翻译值:
/**
* 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);
});
}
字段未映射。翻译属性名称和语言可以直接提供。
/**
* 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
));
}
并输入继承表单基本文本。
public function getParent()
{
return 'text';
}
将其定义为枝条扩展服务(translation_text)后,您可以非常轻松地使用它:
$builder
->add('name')
->add('key')
->add('translate1', 'translation_text',
array(
'translation_property'=>'translate1',
'translation_lang'=>null
))
