Symfony以树枝形式主题获取实体名称

标签: php forms twig entity symfony

我有一些表格类型。然后我正在创建形式,例如。像这样:

$application = new \AppBundle\Entity\Application();
$applicationWidgetForm  = $this->formFactory->create(\AppBundle\Form\WidgetApplicationType::class, $application);

在树枝上,我正在使用

{% form_theme applicationWidgetForm 'form.html.twig' %}

在这个表单主题中,我想获取属性名称和实体名称。我可以获得这样的属性名称(例如,在{%block form_widget%}中):

{{ form.vars.name }}

但我无法弄清楚如何获取映射的实体名称。在这种情况下,我只想在此表单主题中获得类似\AppBundle\Entity\Application() or AppBundle:Application的内容(用作数据属性)。

是否可以通过某种方式获得此值?是的,我可以在每个FormType等中设置它。但我正在寻找更优雅的方式。

谢谢答案!

编辑:整个代码就像这样

控制器

$application = new \AppBundle\Entity\Application();
$applicationWidgetForm  = $this->formFactory->create(\AppBundle\Form\WidgetApplicationType::class, $application);
return $this->render('form/application_detail.html.twig', [
         'applicationForm' => $applicationWidgetForm->createView(),
    ]);

形式/ application_detail.html.twig

 {% form_theme applicationForm 'form.html.twig' %}
 {{ form(applicationForm) }}

form.html.twig

{% block form_widget %}
{{ form.vars.name }} # with this, I can get property name. But what about entity name / class?
{% endblock form_widget %}

你是否通过树枝模板传递了你的实体?渲染Twig模板时,可以将变量传递给View。在您的控制器中:

return $this->render('your_own.html.twig', [
    'entity' => $application,
]);

但请注意您的实体是空的。也许你想渲染表单而不是实体?比你需要将表单传递给视图

return $this->render('your_own.html.twig', [
    'form' => $applicationWidgetForm->createView(),
]);

render the form在你看来。

最终我使用TypeExtension

完成了它
class TextTypeExtension extends AbstractTypeExtension {

/**
 * Returns the name of the type being extended.
 *
 * @return string The name of the type being extended
 */
public function getExtendedType() {
    return TextType::class;
}

public function buildView(\Symfony\Component\Form\FormView $view, \Symfony\Component\Form\FormInterface $form, array $options) {
    $propertyName = $view->vars['name'];
    $entity = $form->getParent()->getData();

    $validationGroups = $form->getParent()->getConfig()->getOption('validation_groups');

    if ($entity) {
        if (is_object($entity)) {

            $entityName = get_class($entity); //full entity name
            $entityNameArr = explode('\\', $entityName);

            $view->vars['attr']['data-validation-groups'] = serialize($validationGroups);
            $view->vars['attr']['data-entity-name'] = array_pop($entityNameArr);
            $view->vars['attr']['data-property-name'] = $propertyName;
        }
    }
}

}
