This osCommerce contribution makes it fast and easy to display products related to the currently-displayed product.
Administrator can easily type in product model numbers to find the product for which you want cross sells, rather than browsing page by page through potentially hundreds or thousands of products
Administrator can easily and quickly add cross sell products to that product by typing their product model numbers
Administrator can immediately see which products are already cross sells for that product
Administrator can easily and quickly delete existing cross sells per product
Tool checks if cross sell products are active before letting Administrator add them
Tool loads and works quickly because only one database table is used, product images are not displayed, and only the searched-for product is shown at one time
Cross sell products display immediately, unless site caching is turned on
If site caching is turned on, it caches the cross sell products per page to reduce overhead
Thanks go to other contributions, like the X-Sells Contribution, which this is partly based on, and for which I have expanded and hopefully made simpler and more efficient to use.
