此集合输入过滤器允许您为集合项定义多个输入过滤器。实用场景是如果您有一个包含不同结构项的数组（集合），那么您需要不同的输入过滤器来过滤/验证集合中的每个项。

示例

class ExampleInputFilter extends InputFilter
{
    public function init()
    {
        $this->add((new MixedCollectionInputFilter())
            ->setNameKey('type')
            ->setInputFilters([
                'picture' => $this->picture(),
                'link' => $this->link(),
                'comment' => $this->comment(),
            ])
            ->setFactory($this->getFactory()), 'content');
    }

    private function picture() : InputFilter
    {
        return (new InputFilter())
            ->add(['name' => 'type'])
            ->add(['name' => 'alt'])
            ->add(['name' => 'src']);
    }

    private function link() : InputFilter
    {
        return (new InputFilter())
            ->add(['name' => 'type'])
            ->add(['name' => 'title'])
            ->add(['name' => 'href'])
            ->add(['name' => 'target']);
    }

    private function comment() : InputFilter
    {
        return (new InputFilter())
            ->add(['name' => 'type'])
            ->add(['name' => 'author'])
            ->add(['name' => 'email'])
            ->add(['name' => 'title'])
            ->add(['name' => 'text'])
            ->add([
                'name' => 'notifications',
                'filters' => [
                    ['name' => \Laminas\Filter\Boolean::class],
                ],
                'validators' => [
                    [

                        'options' => [
                            'haystack' => ['0', '1'],
                        ],
                    ],
                ],
            ]);

$inputFilter = new ExampleInputFilter();
$inputFilter->init();

$data = [
    'content' => [
        [
            'type' => 'picture',
            'alt' => 'Some picture',
            'src' => 'url',

            'email' => 'dummy@email.com',
            'title' => 'Example',
            'text' => 'Got nothing more to say',
            'notifications' => '1',
        ],
        [
