OK, the setup I'm working out is a basic WP install. Within the root there'll be a folder containing a shopping cart (say, 'store') - ecommerecetemplates
I want to be able to have posts, display products as and where I wish using WP. That's easy. Then, if people want to go to the store from a post, I'll create manual links to the purchase page within the store.
The bit I don't understand is, how can I maintain WP sidebar tags within the store - for example, <?php wp_list_categories('title_li='); ?> etc.
Do I put wp-blog-header in the tops of all the pages ? That seems to be for a previous version of WP.
Thanks!
