I find that every build I have requires me looking up the functions to target specific Shopp template pages, so I’m compiling a list for quick reference.
is_account_page()
returns true when the current page request is for the account page
is_cart_page()
returns true when the current page request is for the cart page
is_catalog_frontpage()
returns true if viewing the base catalog landing page request, and not a product taxonomy, product collection, or single product page request.
is_catalog_page()
returns true for WordPress Shopp product taxonomy requests, WordPress Shopp product page requests, and Shopp smart product collection requests
is_checkout_page()
returns true if the requested page is the checkout page
is_confirm_page()
returns true when the current page request is for the confirm order page
is_shopp_collection()
determines if the current request is for a registered dynamic Shopp collection
is_shopp_page()
determines if the requested page is a Shopp page or if the current loaded query is a Shopp product, product taxonomy, or product collection
is_shopp_product()
determines if the current request is for a Shopp product custom post type
is_shopp_taxonomy()
determines if the current request is for a Shopp product taxonomy
is_thanks_page()
determines if the requested page is the thanks/order receipt page
All this information was compiled from the Shopp Development API documentation.
