Question

我可以指定表单字段如何映射到数据类吗？

我们说我的表格带有复选框，在我的数据实体上，该字段存储为字符串。

class FormType extends AbstractType {

    public function configureOptions(OptionsResolver $resolver) {
        $resolver->setDefaults([
            'data_class' => DataEntity::class,
        ]);
    }

    public function buildForm(FormBuilderInterface $builder, array $options) {
        $builder->add('issueType', CheckboxType::class, [
            'label' => 'issueType',
        ]);
    }

}

class DataEntity {

    /** @var string Either PLASTIC or PAPER */
    private $issueType;

    public function getIssueType() {
        return $this->issueType;
    }
    public function setIssueType($issueType) {
        $this->issueType = $issueType;
    }

}

我可以将复选框映射为＆＃39; PLASTIC＆＃39;如果真的和＆＃39; PAPER＆＃39;如果是假的？

Answer 1

您可以使用数据转换器将bolean转换为字符串。请参阅本教程：https://symfony.com/doc/current/form/data_transformers.html。

SELECT * FROM `locations` ORDER BY id DESC limit 1

Answer 2

尝试：

$builder->add('newsletter', 'choice', array(
    'label' => 'Newsletter erhalten',
    'attr' => array(
        'class' => 'form-control',
    ),
    'choices' => array(array('yes' => 'plastic'), array('no' => 'paper')),
    'expanded' => true,
    'multiple' => true,
    'required' => false,
));
