To use forms in an MVC web application, you need to install at least the
zendframework/zend-mvc-form
Composer metapackage:
php composer.phar require zendframework/zend-mvc-form
When you install this metapackage, there will be installed all necessary
components implementing forms in ZF3: Zend\Form
, Zend\InputFilter
, Zend\Filter
, Zend\Validator
,
and probably others.
