Here's a method that is flexible enough for a webstore owner to use in conjunction with their web designer (to apply the css rule).
Scenario: you want the same background image for a category & its children.
1) You apply a layout update to the parent category within the Category manager:
<reference name=”root”><action method=”addBodyClass”><className>caravan-motorhome-lighting</className></action></reference>
2) Set the parent category not to Use Parent Category Settings.
3) Set the child categories to Use Parent Category Settings
4) add body class declaration like so body.caravan-motorhome-lighting{background: url(..)}
You can find a fuller explanation Magento - changing the body class by category
I've used this technique in Magento 1.6.1.0 but should work with earlier versions where you can apply layout updates to a category.
You could do it off category name quite easily. Magento, by default, adds the following to the body tag:
It follows that you could define your stylesheet to work off the
.category-{$category_name}class instead of a.category-{$category_id}, or similar. It would make more sense to the next person that comes along and edits your stylesheet too :)Back to your question, if you would actually like to modify the code and actually used a category ID, then you'd have to modify the category controller, in the usual manner, and add:
..in the
Mage_Catalog_CategoryController::viewAction()at around the same point as the other classes are added.
