Zend Framework Validate field is integer between 1 and 5 - validation

Question

I use Zend\InputFilter\InputFilter class for form validation. point field should accept only integers between 1 and 5. But it doesn't work properly it accepts string starting with integers between 1 and 5. For example 1kjhkjh, 2tgfjhgfjhf, 4jhkljg...
What is wrong in my code?
$inputFilter->add (
$inputFilter->getFactory()->createInput (
array (
'name' => 'point',
'required' => true,
'validators' => array (
array(
'name' => 'Digits'),
array (
'name' => 'Between',
'options' => array (
'min' => 1,
'max' => 5,
'messages' => array('notBetween' => 'Point must be between %min% and %max%')
)
)
)
)
)
);

Answer 1

Use the the second parameter of zend validator to break the validators chain and return an error, breakChainOnFailure (documentation) tells the element to stop validating if this error is triggered, so in your case if it is not a digit the user gets an error, when the user has fixed the error the second validator will get triggered too:
$inputFilter->add (
$inputFilter->getFactory()->createInput (
array (
'name' => 'point',
'required' => true,
'validators' => array (
array(
'name' => 'Digits', 'breakChainOnFailure' => true),
array (
'name' => 'Between',
'options' => array (
'min' => 1,
'max' => 5,
'messages' => array('notBetween' => 'Point must be between %min% and %max%')
)
)
)
)
)
);
Another option would be to replace Zend_Validate_Digits with Zend_Validate_Int (docmentation) depending of what error message you prefer to give to the user if he enters non valid data. Of course as suggested in the comments you could also use the Zend_Filter_Int if what you want is to handle any non valid data by fixing it yourself and do not give the user feedback about what he did wrong.

Answer 2

'breakChainOnFailure': true
should be
'breakChainOnFailure'=> true
