Question 18. What is MVC?

=> MVC is a software approach that separates application logic from presentation.
Question 19. Features of MVC in Zend Framework?
=> Declare custom routing rules
Not limited to “controller/action/param” format
=> Optional Controller Plugins, Action Helpers, and View Helpers
ErrorHandler plugin handles exceptions, 404 errors, etc.
FlashMessenger, Redirector, ViewRenderer helpers
Output common HTML elements in views
=> Extensible interfaces
Write your own plugins and helpers
Question 20. Why can't Zend_Form render my File element without errors?
The file element needs a special file decorator, which is added by default. When you set your own decorators for file elements, you delete the default decorators.
For example:
$element->setDecorators(array(
array('ViewHelper'),
array('Errors')
));
You should use a File decorator instead of the ViewHelper for the file element, like so:
$element->setDecorators(array(
array('File'),
array('Errors')
));
