Question

您好我正在开发一个Sf2项目，我在整个应用程序中重新使用一个包含美国州邮政编码的数组 - 在控制器，验证和表单类中。什么是存储此类和类似“全球”数据的最佳位置，以便将其保存在一个位置？我正在考虑扩展Base Controller类并将其放在那里，但我想我会看到社区的想法。谢谢！

Answer 1

对于美国州邮政编码，我创建了一个自定义FormType，例如Acme\YourBundle\Form\UsPostalCodeType，可用于创建Symfony的FormBuilder的下拉框。

我有一张我用于英国郡县的名单。

<?php

namespace Acme\SomethingBundle\Form;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
use Symfony\Component\Form\Extension\Core\Type\ChoiceType;

class EnglandCountyType extends AbstractType
{
    public function setDefaultOptions(OptionsResolverInterface $resolver)
    {
        $resolver->setDefaults(array(
            'choices' => self::getCounties()
        ));
    }

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

    public function getName()
    {
        return 'england_county';
    }

    /**
     * A custom method to apply the values of the array as the keys also and return that array
     *
     * @return array
     */
    public static function getCounties()
    {
        $choices = array(
            "Greater London",
            "West Midlands",
            "Greater Manchester",

            "Bath and North East Somerset",
            "Southend-on-Sea",
            "North Lincolnshire",
            "Telford and Wrekin",

            "Reading",
            "Wokingham",
            "West Berkshire",
            "Poole",
            "Blackburn with Darwen",
            "Windsor and Maidenhead",
            "Blackpool",
            "Slough",

            "Hartlepool",
            "Rutland",
            "Isles of Scilly",
        );

        asort($choices);

        return array_combine($choices, $choices);
    }
}

要对其进行验证，您可以调用返回选择数组的静态方法作为回调

# src/Acme/SomethingBundle/Resources/config/validation.yml
Acme\SomethingBundle\Entity\Person:
    properties:
        county:
            - Choice: { callback: [\Acme\SomethingBundle\Form\EnglandCountyType, getCounties] }

或在实体中使用注释

use Symfony\Component\Validator\Constraints as Assert;

//....

/**
 * @Assert\Choice(callback={"\Acme\SomethingBundle\Form\EnglandCountyType","getCounties"})
 */
protected $county;

如果您将此用于验证组，则会变为

/**
 * @Assert\Choice(callback={"\Acme\SomethingBundle\Form\EnglandCountyType","getCounties"})
 * @Assert\NotBlank(groups={"group1"})
 */
protected $county;

如果你想在你的控制器中使用它，例如，foreach循环

use Acme\SomethingBundle\Form\EnglandCountyType;

$counties = EnglandCountyType::getCounties();
foreach ($counties as $county) {
    //...
}

我可能会为它创建一个服务，你可以注入任何需要它的服务。
