My form vars are often namespaced, as in <input name="someTable[someField]"
... /> (The idea is stolen from CakePHP, thank you.)
My controllers can then, if need be, recycle form input with a simple
$this->view->someTable = $this->_request->getParam('someTable')
But I am thinking about ajaxifying my current project just because it takes
this issue right off the table (and it's hip and cool).
This is a good and obvious question. There ought to be a Best Practice
enshrined in the ZF Scriptures.
