Zend framework 2 how use validator chains in fieldsets

zend-framework2, zend-inputfilter, zend-validate

Solution

To answer your question we need to look at the InputFilter Factory, there we find the `populateValidators` method. As you can see, for validators it's looking for a `break_chain_on_failure` key in the spec. You just need to add that to your validator spec array...

$factory = new Factory();
$inputFilter = $factory->createInputFilter(array(
    'password' => array(
        'name'       => 'password',
        'required'   => true,
        'validators' => array(
            array(
                'name' => 'not_empty',
                'break_chain_on_failure' => true,
            ),
            array(
                'name' => 'string_length',
            ),
        ),
    ),
));

By the way, the `attachByName` method signatures for `FilterChain` (here) and `ValidatorChain` (here) are not the same. In your first example you're calling the method on a filter chain, which doesn't support break on failure at all. (you might also note that it's the third parameter of the validator chain method and not the second)

Problem

I need to use validator chains in the getInputFilterSpecification method of the fieldset to use the breakChainOnFailure parameter and get only one error message. I know make validator chains using InputFilter classes how explain the zend documentation, e.g. ``` $input = new Input('foo'); $input->getFilterChain() ->attachByName('stringtrim', true) //here there is a breakChainOnFailure ->attachByName('alpha'); ``` But I want make the same using the factory format. Where can I put the breakChainOnFailure parameter in this sample: ``` $factory = new Factory(); $inputFilter = $factory->createInputFilter(array( 'password' => array( 'name' => 'password', 'required' => true, 'validators' => array( array( 'name' => 'not_empty', ), array( 'name' => 'string_length', ), ), ), )); ```
