Re: calling user-defined php functions from <a href> tag

Hmm. Hey, Mathieu. Many thanks for the reply. However, I currently AM using a form. What I'm trying to get away from, is the two step process: 1. pick your option 2. click submit I'm trying to get a one-step process, where the user can click on a link, and that calls the function. JavaScript won't work, because it's client side, and can't be used to call a server-side php function (unless you tell me some neat trick I don't know about yet). See my struggle now?
