How to insert multiple records in one table field and display them?

[367]

Hi,

am using jquery tokeninput (http://loopj.com/jquery-tokeninput/) to search products from products_table and insert them in input field. Now, on submit, i need to save that selected products in order_table, and then display products from that order.
The only idea that i have is to insert id's of products in one field of particular order (something like: 1/3/6/8/9) and then when am displaying order it shows products with that id's. But how to do that?

Thanks
