Php 如何在Symfony表单中将默认选项与新选项合并
我有一个表单和一个子表单,我想合并定义为默认值的约束值和根表单添加的主题 我的子窗体:Php 如何在Symfony表单中将默认选项与新选项合并,php,symfony,symfony-forms,Php,Symfony,Symfony Forms,我有一个表单和一个子表单,我想合并定义为默认值的约束值和根表单添加的主题 我的子窗体: class DatesPeriodType extends AbstractType { public function buildForm(FormBuilderInterface $builder, array $options) { $builder ->add('start', DateType::class, [
class DatesPeriodType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('start', DateType::class, [
'constraints' => [
new Date(),
]
])
->add('end', DateType::class, [
'constraints' => [
new Date(),
]
])
;
}
public function configureOptions(OptionsResolver $resolver)
{
$resolver
->setDefault('error_bubbling', false)
->setDefault('constraints', [
new Callback([$this, 'validate']),
])
;
}
}
我使用新的约束选项将表单添加到根目录:
$builder
->add('judgmentPeriod', DatesPeriodType::class, [
'constraints' => [
new Valid(),
new Callback([
'callback' => [$this, 'datesAreEmpty'],
'groups' => ['insertionPeriod'],
]),
new Callback([
'callback' => [$this, 'validDates'],
'groups' => ['judgmentPeriod'],
]),
]
])
正如预期的那样,约束选项现在包含3个元素,并且回调约束没有合并。
我尝试了这种解决方案:但似乎没有调用回调方法
谢谢,Corentin在您的父表单类型上尝试以下操作:
...
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setNormalizer('constraints', function (Options $options, $value) {
// Merge the child constraints with the these, the parent constraints
return array_merge($value, [
new Assert\Callback(...),
...
]);
});
}
...
在父窗体类型上尝试以下操作:
...
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setNormalizer('constraints', function (Options $options, $value) {
// Merge the child constraints with the these, the parent constraints
return array_merge($value, [
new Assert\Callback(...),
...
]);
});
}
