I have purchased the Cart66 e-commerce plugin and would like to be able to show a number of 'Items for sale' on a single page along with an image and 'Add to Cart button'. I naturally thought that the easiest way to do this would be to create a bunch of Boxes and/or Banners with the appropriate item. However if I try to use a Box or Banner to create the Image & Description I can not place the short code needed for the Cart66 buttons. The support on the Cart66 webpages list a similar type issue for a plugin called Custom Post Types which seems to give an identical situation. The solution provided by Cart66 is to go to the Themes function.php file and add some short code along with the 'slug for the custom post types one wants to use'... Please see the attached file.
So does this mean that there is a 'slug' for Boxes and/or Banners which I can insert in the functions.php file as described that will enable me to enter the short code needed to generate the buttons in the Boxes or Banners ?
