Question

下面是我的Entity，Form和DBAL配置，用于与Symfony2.8集成的misd-phonenumberbundle。但我仍然得到以下错误，有人能告诉我如何解决这个问题吗？我写了几行代码将字符串转换为PhoneNumber obj然后表单加载正常但我的问题是我们需要显式转换它吗？这不是自动处理的吗？

实体条目：

/**
* @ORM\Column(type="phone_number", nullable=true)
* @AssertPhoneNumber(defaultRegion="US", message="Please specify a valid phone number")
*/
private $phoneNumber;

DBAL映射：

doctrine:
dbal:
types:
phone_number: Misd\PhoneNumberBundle\Doctrine\DBAL\Types\PhoneNumberType

形式：

->add('phoneNumber', PhoneNumberType::class, array('default_region' => 'US', 'format' => PhoneNumberFormat::NATIONAL, 'required' => false))

处理错误的自定义代码：

if($user->getphoneNumber()!="")
{
   $util = $this->container->get('libphonenumber.phone_number_util');
   $phoneNUmber = $util->parse($user->getphoneNumber(), "US");
   $user->setphoneNumber($phoneNUmber);
}
else
{
    $phoneNUmber = new \libphonenumber\PhoneNumber;
    $user->setphoneNumber($phoneNUmber);
}

Error:

以下是我的解决方案。我没有在app / config.yml中做过任何学说映射

此解决方案假定MisdPhonenumber包已在AppKernel.php中注册

创建数据转换器：src / Example / Bundle / Form / DataTransformer.php

Data Transformer Class

<?php

namespace Example\Bundle\Form\DataTransformer;

use libphonenumber\PhoneNumber;
use libphonenumber\PhoneNumberFormat;
use Symfony\Component\Form\DataTransformerInterface;

class StringToPhoneNumberTransformer implements DataTransformerInterface 
{

    // The 'libphonenumber.phone_number_util' service 
    private $phoneNumberUtil; public function __construct($util)
    {
        $this->phoneNumberUtil = $util; 
    }

    /**
     * Transforms a string (number) to an object (PhoneNumber)
     *
     * @param  string $phoneNumberString
     * @return PhoneNumber
     */
    public function transform($phoneNumberString)
    {
        if ($phoneNumberString != "")
        {
            return $this->phoneNumberUtil->parse($phoneNumberString, "US");
        }
        return new PhoneNumber;
    }

    /**
     * Transforms a string (number) to an object (issue).
     *
     * @param  PhoneNumber $phoneNumberObject
     * @return string
     */
    public function reverseTransform($phoneNumberObject)
    {
        if ($phoneNumberObject != null)
        {
            return $this->phoneNumberUtil->format($phoneNumberObject, PhoneNumberFormat::NATIONAL);
        }
        return '';
    }
}

使用表单中的数据转换器

Data Transformer in Form

<?php

namespace Example\Bundle\Form\Type\User;

use Example\Bundle\Entity\User;
use Example\Bundle\Form\DataTransformer\StringToPhoneNumberTransformer;
use Example\Bundle\Services\States;
use libphonenumber\PhoneNumberFormat;
use Misd\PhoneNumberBundle\Form\Type\PhoneNumberType;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\Extension\Core\Type\ChoiceType;
use Symfony\Component\Form\Extension\Core\Type\EmailType;
use Symfony\Component\Form\Extension\Core\Type\SubmitType;
use Symfony\Component\Form\Extension\Core\Type\TextType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;

class ContactInfoType extends AbstractType
{
    // The 'libphonenumber.phone_number_util' service private $phoneNumberUtil;
    public function __construct($util)
    {
        $this->phoneNumberUtil = $util;
    }

    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->add('salutation', TextType::class, array('max_length' => 10, 'required' => false))
            ->add('firstName', TextType::class, array('max_length' => 30))
            ->add('lastName', TextType::class, array('max_length' => 30))
            ->add('email', EmailType::class, array('max_length' => 150))
            ->add('phone', PhoneNumberType::class,
                array('default_region' => 'US', 'format' => PhoneNumberFormat::NATIONAL, 'required' => false))
            ->add('stAddress1', TextType::class,
                array('label' => 'Address Line 1', 'max_length' => 60, 'required' => false))
            ->add('stAddress2', TextType::class,
                array('label' => 'Address Line 2', 'max_length' => 60, 'required' => false))
            ->add('city', TextType::class, array('max_length' => 30, 'required' => false))
            ->add('state', ChoiceType::class,
                array('choices' => States::getStates(), 'required' => false, 'choices_as_values' => true))
            ->add('zip', TextType::class, array('max_length' => 5, 'required' => false))
            ->add('submit', SubmitType::class);

        $builder->get('phone')->addModelTransformer(new StringToPhoneNumberTransformer($this->phoneNumberUtil));
    }

    public function getBlockPrefix()
    {
        return 'ContactInfo';
    }

    public function configureOptions(OptionsResolver $resolver){
        // Explicitly bind data class of form.
        $resolver->setDefaults([
            'data_class' => User::class
        ]);
    }
}

在配置文件中将表单类型定义为服务：

Form type as a service

# src/Example/Bundle/Resources/config/services.yml

services:
    example.form.contactinfo:
        class: Example\Bundle\Form\Type\User\ContactInfoType
    arguments: ["@libphonenumber.phone_number_util"]
    tags:
        - { name: form.type }
