问题描述
限时送ChatGPT账号..我有一个 moneyFieldset,有 2 个字段,金额和货币.
I have a moneyFieldset with 2 fields, amount and currency.
class MoneyFieldset ...
{
public function __construct($name = null, $options = array())
{
parent::__construct($name, $options);
$this->setHydrator(...);
$this->add(array(
'name' => 'currency',
'type' => 'select',
'options' => array(
'value_options' => \Core\Service\Money::getAvailableCurrencies(true),
),
'attributes' => array(
'value' => \Core\Service\Money::DEFAULT_CURRENCY,
),
));
$this->add(array(
'name' => 'amount',
'type' => 'text',
));
}
}
public function getInputFilterSpecification()
{
$default = [
'amount' => [
'required' => false,
'allow_empty' => true,
'filters' => [
['name' => AmountFilter::class]
],
'validators' => [
]
],
'currency' => [
'required' => false,
'allow_empty' => true,
'filters' => [
['name' => StringToUpper::class]
],
'validators' => [
]
]
];
return \Zend\Stdlib\ArrayUtils::merge($default, $this->filterSpec, true);
}
我在其他字段集中使用 moneyFieldset,如下所示:
I'm using moneyFieldset in my other fieldsets like this:
// Price Field
$this->add(array(
'name' => 'price',
'type' => 'form.fieldset.moneyFieldset',
'attributes' => array(
'required' => true,
'invalidText' => 'Please type an amount'
),
'options' => array(
...
),
));
当我这样设置过滤器时:
When I set filter like this:
function getInputFilterSpecification()
{
'price' => [
'required' => true,
'allow_empty' => false,
],
}
它不起作用,因为 price 有 2 个字段,所以我怎么能说 price[amount] 和 price[curreny] 是必需的?
It's not working because price has 2 fields, so how can I say price[amount] and price[curreny] is required?
推荐答案
您可以使用以下数组结构为嵌套字段集(在表单的上下文中)提供输入规范.
You can provide the input specifications for the nested fieldset (within the context of the form) using the following array structure.
public function getInputFilterSpecification()
{
return [
// ...
'price' => [
'type' => 'Zend\InputFilter\InputFilter',
'amount' => [
'required' => true,
],
'currency' => [
'required' => true,
]
],
//...
];
}
如果您要动态修改输入过滤器的值,可能值得考虑使用服务工厂类创建验证器,然后使用对象 API 而不是数组将其附加到表单.
If you are dynamically modifying the values of the input filter it might be worth considering creating the validator using a service factory class and then attaching it to a form using the object API rather than arrays.
