If you’ve got a website, you’ve probably got one or more forms on it. Since visitors usually don’t want to take the time to fill out the full form - and we do want all the obligatory information - we all have to use form validation. Me personally, I like to do my validation server-side, because if a visitor really wants to annoy you he (or she for PC’s sake) will disable client-side scripts. Yes, that is right, they do it; I’ve seen them do it. All your hard work and all your scripting goes down the drain and you are left empty-handed if you used them. I’ve worked a lot with forms, and I’ve come up with my own little standard way of doing this. The example I’ll give is in PHP since there’s an area for it on this website.
