I'm working in Vtiger (MVC set up), The modules contain the MVC files. Modules extend other modules by extending the class of the other module. In the case I am looking at, the Quote extends the Inventory module. The outcome is a custom block inside the Quote, not a whole new "page".
I want that "block" which is really a whole module. So this should be simple, except that I ran into PHP "inheritance" issues. The class I need to extend is an extended class already.
My logic was: ( B gets C ) works! now A gets B stuff. This did not work.
The Parent Class Class Event extends Calendar (shows event details / "final page")
The exiting "working" class Class Event extends Inventory (creates new block)
I need these two classes to communicate, since Calendar already "talks" to Events, and Events talks to Inventory, the variables are unrelated, but I cannot get the Output to work, I assume because of class "inheritance"
So the direct question is: can an existing child class be extended?
- Stack addresses this in few posts but I'm not able to "grasp" how this applies here since no variables are shared, there should not be any bad obj calls.
Here are my resources for learning to "connect" child classes:
- Stack Solution - should have worked
- php.net - Example #2 Extendable Interfaces
- killerphp.com - When and Why to use interfaces
I tried to explain my reference to the problem as it may not be php related but rather my understanding. Thank you in advance.
