php - problem in many to many relationship -

-

i have 2 tables jewelry(j_id,j_name,description) , style(style_id,style_name,image) each table has many many relationship other table, 1 jewelry product can have multiple styles , there more product of same style, relationship many many.

now question how can relate these tables i.e want insert single record in jewelry table , there should multiple styles 1 jewelry product.

on jewelry html page want put style in multiple select dropdown list populated dynamically style table , if user want select 2 style same product, can.

i recommend 4 tables, 3 jewellery , style , fourth 1 orders.

jewellery : jid (pkey),jname,description

style: sid (pkey), sname, description

product : pid (pkey), sid(fkey), jid(fkey) - 1 product defines unique combination of style , kewellery

order : oid(pkey), pid(fkey), other details(name, address etc.)

for each jewellery, recover associated styles using product table , populate fields on html page. each order, store product id, uniquely identifies both jewellery , style.
