I want to set the value of a view-variable (a) a variable that is already
defined under controller's view object (2) assigning new variable to view
object, in my custom helper, as follows;
public function formAssembly()
{
$this->view->title = "This is Form Assembly"; // title is
already set in
controller
$this->view->ahmed = "World is helloed"; // new variable
in the helper
}
While in my view (.phtml) file I am calling the helper as;
$this->formAssembly()
And in my controller;
public function createAction()
{
$this->view->title = "Create Form";
$this->view->addHelperPath("../../views/helpers","FormAssembly");
}
But
(1) the title is not getting overwritten when displayed. Seems like _title_
under controller is getting preference or the output is being rendered
before the helper call
(2) the new variable _ahmed_ is not being used in the view file. Seems like
view object is not being passed as reference
Any help?
