I'm desiging a form which uses fields drawn out of a mysql db. I've already managed to figure out how to display a drop-down menu that's drawn from a mysql table. My problem, however, is with a sub-menu. Basically, it's a form that's supposed to give network technicians some information about the clients to which they're sent. Whoever fills out the form picks a router/fw type from a drop-down menu (connected to a table in the mysql db), and then a sub-menu is supposed to open up, another drop-down, from which they pick the specific model. I've created one big table containing all the models we use, and it can be sorted according to manufacturer. My question is - I want to have one single query made from the db (SELECT *), from which I can extract the appropriate records later. I suppose I need to set up an array, but i'm not sure how to... Could use your help :)
