Custom Component 3 levels deep

Question

IM building a component and im trying to work out how to do this

Bookings / Orders / Order

I have a bookings view and form I have a orders view and form

However...

Im having trouble getting bookings to show orders based on booking id. I have added to the models file WHERE bid=GET[bid]

However that messes things up when coming back from editing an order.

The steps are

• click bookings
• view orders based on booking id ( my custom hack in the models file for orders )
• open order
• edit order
• click save
• return to orders view where booking id=booking id

I can manage this by adding a little hack into the controllers order.php file

but...

That works for saving and going back and yet it crashes all other actions like publish,archive etc..

There must be a section in the mvc where i can put the additional &bid=$_GET['bid'] and it works across all submission actions.

What is the correct way to build a component with views that are parent to each other.

Im happy to provide code but theres quite a lot. So maybe if you could direct me first.

some other notes:

here is my link to the orders from the bookings view

JRoute::_('index.php?option=com_tourbookings&view=orders&bid='.(int) $row->id)

Here is my hack within the models/orders.php

$query->where('a.bid = '.$_GET['bid']);

So far that works good, if i click it ill get the orders based on bid.

Then i am lost. Because if i try to hack from here i am completely stuck as it wont come back to the orders based on bid without crashing.

If i hack the controllers/order.php ( which has changed again in joomla 3.3+ )

I find that it kind of works and allows me to go back to the previous page with bid=bid attached but if i try to archive,unpublish or do anything of that sort im stuck.

Cheers John

The question is very general. At first glance:

• The question depends on how you are implementing a MVC in Joomla! and which Controller flavour are you following. In my perspective, I avoid any MVC issue just relaying on FoF, instead of elucidating how to implement a native controller in Joomla 2.5, 3, or 3.x.
• DO NOT use $_GET, for security reasons. Instead of using the raw variables, implement JInput. For example, FoF implements F0FInput, extending JInput.
