I want to add more than one function to a ViewHelper. Usually there is one function named like the class and like the file name.
How can I add several functions into one ViewHelper?
Eg like this:
class Zend_View_Helper_MyMenuHelper extends Zend_View_Helper_Abstract
{
public function Horizontal($parameter)
{
return "...";
}
}
echo $this->MyMenuHelper()->Horizontal($parameter);
Alex was on the right path, but missed something in his answer: the actual myMenuHelper()
method has to return the view helper itself, for this to work:
class Zend_View_Helper_MyMenuHelper extends Zend_View_Helper_Abstract
{
public function myMenuHelper()
{
return $this;
}
public function horizontal() { ... }
// more methods...
}
And then, as mentioned:
echo $this->myMenuHelper()->horizontal();
Sometimes you don't want to pass through the main method of a view helper, although it's not that bad for some kinds of logic. In that case, use getHelper()
:
class Zend_View_Helper_MyMenuHelper extends Zend_View_Helper_Abstract
{
public function myMenuHelper()
{
// some logic, maybe the main one
}
public function horizontal()
{
// some other logic
}
}
The following examples bypass myMenuHelper()
completely:
// in controller
$this->view->getHelper('MyMenuHelper')->horizontal();
// in view
$this->getHelper('MyMenuHelper')->horizontal();`
In some cases for example, I populate the view helper with some internal data in the controller , the call its main method directly in the view , which acts on that data.
// in controller
$this->view->getHelper('MyMenuHelper')->storeData($someArray);
// in view
$this->myMenuHelper(); // iterates over $someArray
try to start the function name with a lower case letter
class Zend_View_Helper_MyMenuHelper extends Zend_View_Helper_Abstract
{
public function horizontal($parameter)
{
return "...";
}
}
in the view:
echo $this->myMenuHelper()->horizontal($parameter);
