我想做这样的事情:
$builder->add('firstname', 'text', array(
'myCustomOption' => 'optionValue'
));
所以我可以在myForm.html.twig中使用myCustomOption
,如下所示:
{% block form_row -%}
{{ myCustomOption }}
{%- endblock form_row %}
但在这种情况下,我得到:
选项" myCustomOption"不存在。已知的选项是:[..]

这就是答案:类型扩展
它允许扩展所需的表单类型email/phone/checkbox
或组text/entity/choice
,甚至可以扩展所有可用的form
。
(请记住,一个元素可以包含少量类型。例如,输入email
将是form, text, email
的类型
只需创建扩展程序类:
use Symfony\Component\Form\AbstractTypeExtension;
use Symfony\Component\Form\FormView;
use Symfony\Component\Form\FormInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
class TextTypeExtension extends AbstractTypeExtension {
public function getExtendedType() {
return 'form'; // What type should be extended
}
public function setDefaultOptions(OptionsResolverInterface $resolver) {
// Add optional option - you can also add required options
// and available values of this option
$resolver->setOptional(array('myOption'));
}
public function buildView(FormView $view, FormInterface $form, array $options) {
// You can put any logic here
// For example 'myOption' => 'big' can be transformed to
// 'myOption' => '300px'
if (array_key_exists('myOption', $options)) {
// Add your option to twig template
$view->vars['myOption'] = $options['myOption'];
}
}
}
将课程添加为服务:
services:
acme_demo_bundle.image_type_extension:
class: Acme\DemoBundle\Form\Extension\TextTypeExtension
tags:
- { name: form.type_extension, alias: form }
现在你可以这样做:
$builder->add('MyInput', 'text', array('myOption' => array('whateverYouNeed')));

尝试这样的事情:
class MyTextType extends AbstractType
{
public function getParent()
{
return 'text';
}
public function getName()
{
return 'my_text';
}
....
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver
->setDefaults([
'myOption' => null
])
;
}
....
}
服务定义:
acme_demo_bundle.text_type:
class: Acme\DemoBundle\Form\Type\MyTextType
tags:
- { name: form.type, alias: my_text }
用法:
$builder->add('someName', 'my_text', ['myOption' => $value])
