Hiding product images under one category but not another

[robgt]

Hi,
The product listing page displays with Image, Description, Price, etc columns.
This is fine for most pages, but how would I go about not displaying that product image when that same product is displayed under a different category (as a linked product in admin).

I can't provide a site URL I'm afriad, but hopefully the question is self explanatory?
Any ideas/suggestions?

I've hunted through the forums without success so far.
Cheers,
Rob

You could edit /includes/modules/your_template/product_listing.php to include a test for $cPath being equal to the category you wish to hide...

Gallery Category does exactly the kind of thing you want for the price and add button; you could transfer the logic to the image case and hide that on your selected categories.

Thanks for the speedy reply.
Having read several threads on testing the $cPath - I have a question that relates to my main question.

If I have a category ID=20, would checking $cPath for 20 and hiding a column in product_listing.php carry through to sub categories of category 20 (20_243 etc), or do I have to specify all those sub categories too?

If so, I'm not sure how I might proceed, as there are a lot of categories and sub-categories within them that I want this modified product listing layout on - but it can't affect the rest of the site.

If this is the only way to go (adding them all manually) then ok... but could you suggest a code snippet to help me on my way please?
Cheers,
Rob

There are a couple of ways to test for the top category in $cPath.
I'll go look one up.

Here is one way. Replace 23 with your desired category id:

if (ereg("(^23$|^23_)",$cPath)) { //do something in category 23 and its subcats (replace 23 with your cat id)
  your code;
}

Thank you for looking that up for me - very much appreciated!

I'll give it a go and post back if I have any further issues with it

Would I be right in thinking that to have the same effect on several top level categories and their sub cats, I could just keep adding the or pipe | and another pair of numbers, one with underscore?

i.e. (^23$|^23_|^45$|^45_) etc...
