Configuration-based setup of zend-validator, zend-filter and zend-inputfilter for Zend Expressive applications.

This package provides factories that allow to define custom filters and validators using configuration:

return [
    'filters' => [
        'factories' => [
            'Foo' => FooFilterFactory::class,
        ],
    ],
    'validators' => [
        'factories' => [
            'Bar' => BarValidatorFactory::class,
        ],
    ],
];

Later on they can be used directly when building an input filter:

$filter = $factory->createInputFilter(
    [
        [
            'name' => 'name',
            'filters' => [
                ['name' => 'Foo'],
            ],
            'validators' => [
                ['name' => 'Bar'],
            ],
        ],        
    ]
);

return $filter;

Installation

This package supports installation with composer:

$ composer require mtymek/blast-input-filter

Usage

Define your custom filters and validators

blast-inputfilter allows to set-up respective plugin managers using filters and validators keys:

return [
    'filters' => [
        'factories' => [
            'Foo' => FooFilterFactory::class,
        ],
    ],
    'validators' => [
        'factories' => [
            'Bar' => BarValidatorFactory::class,
        ],
    ],
];

This works exaclty like when using zend-mvc, only without performance penalty of ZF's module manager.

Create input filter

There are couple of ways of creating input filter and injecting it with elements. One of them is to use __construct method to create all inputs and specify validators:

namespace App\InputFilter;

use Zend\InputFilter\InputFilter;

class ContactInputFilter extends InputFilter
{
    public function __construct()
    {
        $this->add(
            [
                'name' => 'name',
                'filters' => [
                    ['name' => 'Foo'],
                ],
                'validators' => [
                    ['name' => 'Bar'],
                ],
            ]
        );

        $this->add(
            [
                'name' => 'content',
                'filters' => [
                    ['name' => 'StringTrim'],
                ],
            ]
        );
    }
}

Create factory for your filter

In order for custom filters and validators to work, you need to pull Zend\InputFilter\Factory from service container and inject it into your input filter:

namespace App\InputFilter;

use Interop\Container\ContainerInterface;
use Zend\InputFilter\Factory;

class ContactInputFilterFactory
{
    public function __invoke(ContainerInterface $container)
    {
        $inputFilter = new ContactForm();
        $inputFilter->setFactory($container->get(Factory::class));
        return $inputFilter;
    }
}

Please note that you can use more generic factory to instantiate more input filters:

namespace App\InputFilter;

use Interop\Container\ContainerInterface;
use Zend\InputFilter\Factory;

class InputFilterFactory
{
    public function __invoke(ContainerInterface $container, $requestedName)
    {
        $inputFilter = new $requestedName();
        $inputFilter->setFactory($container->get(Factory::class));
        return $inputFilter;
    }
}
