Hello, is there any universal/unique cart system in blesta? Suppose customer added some item in cart from a 'domain' form. Now customer goes to another form, say 'vps' form and order a vps. Now, is there anyway to checkout those items in a single cart instead of doing the checkout separately from individual carts? I couldn't find this option. So we tried to implement this. We have some issues: 1.How can we handle the session varibale data element by element? 2.Is there any speciality in the SESSION of blesta ? 3. Is there available some collections of tutorials ? 4.How can we easily handle the muldimensional arrays ? 5. How does database work? 6. are the pages working through any routing file like laravel ? 7. How can we access the database easily ? Even we able to show all the cart items in any forms cart, we can't get into the checkout page. The site gets broken. Can anyone have any suggestion how to implement universal/unique cart system in blesta? Thanks
