Add Category description to Order Confirmation

I have multiple categories, each category has mutilple sub-categories and each sub-category has sub-sub-categories.
Only then do I get to product,

Is it possible to add the catagory path text to the order confirmation? I imagine this would need code adding to the relevant template.

Can anyone help out with this code please or if someone could identify the the template file and the appropriate field names I can have a go myself.

Any help greatly appreciated.

I found a better way to do this - so wont be going down this route

I am curious about your solution? Can you explain please...

Yes -

I decided to reorganise the way tickets were categorised.
I have 'Adult' tickets in 'General Tickets'
In 'Special Events' I have subcategories - one for each special event - where a special event is over, say, 2 days
There will be sub-subcategoreies for, say, Sunday and Monday
In each day I will have 'Adult Tickets' (and children, family, senior citizen tickets'

Rather than have long descriptions ie 'Adult, Easter Bunny Event, Monday' for the product name I am just using 'Adult Tickets'

The problem was that on the confirmation email, and invoice, it just says 'Adult Ticket' so I wanted the path so I knew which event/day the ticket was for - so I was thinking of using the path.

However I realised it was simpler to add a text attribute to each ticket with the ticket detail set as 'attribute' value appears on the email/invoice

Got to admit though - I havent tried it yet
I have used attributes where the buyer enters text, but not a 'read only' field - but in theory it should work

Well - it works - but not quite as planned.
I used 'Model No', I gave Tickets a model no. in the form
xxxx-yy
yy is 01/02/03/04 - Adult/Child/Senior/Family
xxxx is Gen/East/Whit/etc - General/Easter/Whit/ etc to indicate which event
I added a radio button type attribute (I have only done easter - I know its a bit late but this is for future use)
to select Sunday or Monday
I tried not setting a default and making the options required - but that doesn't seem to work - you can proceed without making either selection, so I have set a default

The confirmation email and the invoice show the model no. Identifying the event, the description and model no. give the ticket type and the radio button selection is included which shows which day:cool:
