Then you should store the cart info in the database or in SESSION data. But, to answer your question directly you can pass variables from the client to the server using Javascript by performing an AJAX request - which I wouldn't suggest for cart info.

That question cannot be answered. The appropriate number of "queries" (or what I think you mean is how much data should be stored) is completely dependent upon the needs of the application. If the needs of the application requires 5 queries or 500 queries then that is what it takes.

 

To address your specific need, you are wanting to store a user's cart. There are a few different solutions and which one you choose can depend on many factors.

 

You can use sessions, but they will only persist for the user's session (obviously). This is pretty easy to manager.

 

You can store the info in cookies, which will persist across sessions. But, if a user saves a cart it would only be available to them on that same pc.

 

If you want carts to persist across sessions and PCs then you will want to store them in the DB and ties to a user login.

 

There is no right or wrong method - it depends on which one meets your specific needs. Many sites use several methods.
