Zend Framework 2: How to mark form invalid?

Question

In ZF1 it was possible to mark the form invalid using the code:

$form->fieldname->addError('error message');

How can I do it in ZF2? I tried

$form->get('elementName')->setMessages(array('error message'));

but it doesn't make the form invalid.

I think this will be of great help for you http://stackoverflow.com/questions/13476164/zend-framework-2-custom-validators-for-forms also this link http://www.ivangospodinow.com/simple-form-validator-for-zend-framework-2-forms/ — Programmer man, Oct 06 '14 at 13:59
@peterpeterson The Form class doesn't have "setValid" method. Where did you get it? — Alexey Kosov, Jul 17 '15 at 12:12
just trying to guess as all method in ZF2 that are things like is....() they usually have the set....() method. but it doesn't seem to in this case — peterpeterson, Jul 19 '15 at 06:58

I wonder the same question and I dont know how to do it easy too with default Zend 2 forms.

I have no idea why it was necessary to hide manual form state manipulating and break obvious addError functionality too.

But may be it's appropriate to you to use proxy-way like this:

Create own form basic class (may be write it better later):

class BasicForm extends Form
{
    protected _isValid = null;

    public function isValid()
    {
        return isset($this->_isValid) ? $this->_isValid : parent::isValid();
    }

    public function setValid($value)
    {
        $this->_isValid = isset($value) ? (bool)$value : null;
        return $this;
    }

}

Instantiate your real forms from this custom form class intead of default Zend Form class:
```
class SomeYourForm extends BasicForm
...
```

So you will be able to set this form valid state to true or false by overlaying of this property.

May be it helps for someone too.
