README

一个非常简单的bundle，允许您翻译实体。

参考仓库。

https://github.com/vm5/EntityTranslationsBundle

安装

composer require perfectneeds/locale-bundle "~1.0"
在AppKernel.php中注册bundle： new VM5\EntityTranslationsBundle\VM5EntityTranslationsBundle()
将LocaleBundle复制到您的项目中src/PN/Bundle
在AppKernel.php中注册bundle： new PN\LocaleBundle\LocaleBundle()
为每种语言添加消息文件到app/Resources/translations中，命名为messages.{LOCALE}.php（例如：messages.ar.php）
您必须在config.yml中添加此代码

parameters:
    locale: en
    app.locales: en|ar|
    
doctrine:
   orm:
        # search for the "ResolveTargetEntityListener" class for an article about this
        resolve_target_entities: 
            VM5\EntityTranslationsBundle\Model\Language:

更改API方法中的Locale

$this->get('vm5_entity_translations.translator')->setLocale('ar'); //translate entities
$this->get('translator')->setLocale('ar'); // translates messages

路由示例

cms:
    resource: "@CMSBundle/Controller/FrontEnd/"
    type:    annotation
    prefix: /{_locale}
    defaults:  {_locale: '%locale%' }
    requirements:
        _locale: '%app.locales%'

实体示例

<?php

namespace PN\Bundle\CMSBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use VM5\EntityTranslationsBundle\Model\Translatable;
use PN\LocaleBundle\Model\LocaleTrait;

/**
 * Blogger
 *
 * @ORM\HasLifecycleCallbacks
 * @ORM\Table(name="blogger")
 * @ORM\Entity(repositoryClass="PN\Bundle\CMSBundle\Repository\BloggerRepository")
 */
class Blogger implements Translatable {

    use LocaleTrait;

    /**
     * @var int
     *
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;

    /**
     * @var string
     *
     * @ORM\Column(name="title", type="string", length=255)
     */
    protected $title;

    /**
     * @ORM\OneToMany(targetEntity="PN\Bundle\CMSBundle\Entity\Translation\BloggerTranslation", mappedBy="translatable", cascade={"ALL"}, orphanRemoval=true)
     */
    protected $translations;

    /**
     * Now we tell doctrine that before we persist or update we call the updatedTimestamps() function.
     *
     * @ORM\PrePersist
     * @ORM\PreUpdate
     */
    public function updatedTimestamps() {
        $this->setModified(new \DateTime(date('Y-m-d H:i:s')));

        if ($this->getCreated() == null) {
            $this->setCreated(new \DateTime(date('Y-m-d H:i:s')));
        }
    }

    /**
     * Constructor
     */
    public function __construct() {
        $this->translations = new \Doctrine\Common\Collections\ArrayCollection();
    }

    /**
     * Get id
     *
     * @return int
     */
    public function getId() {
        return $this->id;
    }

    /**
     * Set title
     *
     * @param string $title
     *
     * @return Blogger
     */
    public function setTitle($title) {
        $this->title = $title;

        return $this;
    }

    /**
     * Get title
     *
     * @return string
     */
    public function getTitle() {
        return !$this->currentTranslation ? $this->title : $this->currentTranslation->getTitle();
    }

}

在CMSBundle/Entity/Translation中的BloggerTranslation.php

<?php

namespace PN\Bundle\CMSBundle\Entity\Translation;

use Doctrine\ORM\Mapping as ORM;
use VM5\EntityTranslationsBundle\Model\EditableTranslation;
use PN\LocaleBundle\Model\TranslationEntity;

/**
 * @ORM\Entity
 * @ORM\Table(name="blogger_translations")
 */
class BloggerTranslation extends TranslationEntity implements EditableTranslation {

    /**
     * @var string
     *
     * @ORM\Column(name="title", type="string", length=255)
     */
    protected $title;

    /**
     * @var 
     * @ORM\Id
     * @ORM\ManyToOne(targetEntity="PN\Bundle\CMSBundle\Entity\Blogger", inversedBy="translations")
     */
    protected $translatable;

    /**
     * @var Language
     * @ORM\Id
     * @ORM\ManyToOne(targetEntity="PN\LocaleBundle\Entity\Language")
     */
    protected $language;

    /**
     * Set title
     *
     * @param string $title
     *
     * @return Blogger
     */
    public function setTitle($title) {
        $this->title = $title;

        return $this;
    }

    /**
     * Get title
     *
     * @return string
     */
    public function getTitle() {
        return $this->title;
    }

}

然后您可以自己翻译它们

$blogger = new Blogger();

// Arabic 
$arabicTranslation = new BloggerTranslation();
$arabicTranslation->setLanguage($arabicLanguage);
$arabicTranslation->setTitle('Title on arabic');
$blogger->addTranslation($arabicTranslation);

// French
$frenchTranslation = new BloggerTranslation();
$frenchTranslation->setLanguage($frenchLanguage);
$frenchTranslation->setTitle('Title on french');
$blogger->addTranslation($frenchTranslation);

$em->persist($blogger);
$em->flush();

使用表单轻松翻译实体。

创建BloggerTranslationType类

在CMSBundle/Form/Translation/BloggerTranslationType.php

添加所有可翻译列，如BloggerTranslation.php（实体）

<?php

namespace PN\Bundle\CMSBundle\Form\Translation;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;

class BloggerTranslationType  extends AbstractType {

    /**
     * {@inheritdoc}
     */
    public function buildForm(FormBuilderInterface $builder, array $options) {
        $builder->add('title')
        ;
    }

    /**
     * {@inheritdoc}
     */
    public function configureOptions(OptionsResolver $resolver) {
        $resolver->setDefaults(array(
            'data_class' => \PN\Bundle\CMSBundle\Entity\Translation\BloggerTranslation::class
        ));
    }

    /**
     * {@inheritdoc}
     */
    public function getBlockPrefix() {
        return 'pn_bundle_cmsbundle_blogger';
    }
}

在您的主表单中添加翻译字段到BloggerType.php

<?php

namespace PN\Bundle\CMSBundle\Form;

use Doctrine\ORM\EntityRepository;
use Symfony\Bridge\Doctrine\Form\Type\EntityType;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;
use VM5\EntityTranslationsBundle\Form\Type\TranslationsType;
use PN\Bundle\CMSBundle\Form\Translation\BloggerTranslationType;
use PN\Bundle\CMSBundle\Entity\BloggerTag;
use PN\Bundle\SeoBundle\Form\SeoType;

class BloggerType extends AbstractType {

    /**
     * {@inheritdoc}
     */
    public function buildForm(FormBuilderInterface $builder, array $options) {
        $builder->add('title')
                ->add('publish')
                ->add('seo', SeoType::class)
                ->add('post', PostType::class)
                ->add('translations', TranslationsType::class, [
                    'entry_type' => BloggerTranslationType::class,
                    'entry_language_options' => [
                        'en' => [
                            'required' => true,
                        ]
                    ],
                ])
        ;
    }

    /**
     * {@inheritdoc}
     */
    public function configureOptions(OptionsResolver $resolver) {
        $resolver->setDefaults(array(
            'data_class' => 'PN\Bundle\CMSBundle\Entity\Blogger'
        ));
    }

    /**
     * {@inheritdoc}
     */
    public function getBlockPrefix() {
        return 'pn_bundle_cmsbundle_blogger';
    }

}

对于特定区域，将entry_language_options中的required包括在内很重要，因为验证仅在语言不为空或为必填时触发。

如果至少有一个字段被填写，则假定语言不为空。
