There are two problems here. First, don't override the constructor.
You're doing it wrong above, because it's not following the signature of
Zend_Controller_Action::__construct(), which is why you're getting the
issues you have below (it expects a request object, response object, and
an array of parameters injected from the dispatcher). We provide another
method you can call if you need specialized initialization: init():
class MyController extends Zend_Controller_Action
{
public function init()
{
/* ... */
}
}
Second, there are two better ways to do this. One is to use the
controller's _getParam() method with a second argument indicating the
default to use, and the second is to do as you do above, but, again,
passing the second argument, which indicates a default value; I'd
personally use _getParam() as it'll lead to more succinct syntax.
class MyController extends Zend_Controller_Action
{
public function init()
{
$this->value = $this->_getParam('value', 0);
}
}
The above should accomplish what you're expecting.
