Registering a custom validator in Zend 2

Question

I create a custom date Validator. But I keep getting this error message :

"Zend\\Validator\\ValidatorPluginManager::get was unable to fetch or create an instance for date_validator"

I did some research and tried adding in module.config.php after the view manager array.

'validators' => array(
    'invokables' => array(
        'date_validator' => 'Administrativo\InputFilter\Date_Validator'
    ),
),

What am I missing here?

Answer 1

Your configuration seems okay.

Are you sure you have a file (invokable class) with the name Date_Validator in a folder Administrativo\\InputFilter in your module?

Is the namespace inside this class Administrativo\\InputFilter and is the class name Date_Validator .

It is important that both the class name and namespace have to be correct as well as the folder names and file name . Otherwise the PluginManager will not be able to find your file.

UPDATE

If all that is fine then there is something else you should check.

If you build your input filters through config array then you should make sure that the factory inside your InputFilter class holds a correctly populated InputFilterPluginManager instance (with both ValidatorManager and FilterManager on board). Otherwise it will not inject those classes in the setInputFilterManager method and it will later create a new empty plugin manager instance which will obviously not hold your validator class.
