Pre validation filters concept

[autowp]

Example situations:

• E-mail validation requires trim extra spaces before the check.
• Phone number validation requires filter unexpected character.
• Filename validator may require ToLowerCase filter

Take a look at zend-inputfilter and zend-filter, zend-validator subpackages

$inputFilterConfig = [
    'amount' => [
        'filters'  => [
            ['name' => 'StringTrim']
        ],
        'validators' => [
            ['name' => 'Digits'],
            [
                'name' => 'Between',
                'options' => [
                    'min' => 1,
                    'max' => 10
                ]
            ]
        ]
    ],
    'email' => [
        'filters'  => [
            ['name' => 'StringTrim'],
            ['name' => 'ToLowerCase'],
        ],
        'validators' => [
            ['name' => 'EmailAddress']
        ]
    ]
];

Thanks for the suggestion. I do not have plan to support data filtering in this package, for the reason of separation of concerns. It can be in a separate package.

It's also trivial to add your own pre-filtering as part of your Validate method.
