Here is something that I have found useful from Montana Programmer

But there are many other tutorials and I recommend you do a Google search for "php form validation."

But Nancy's answer is really bugging me here. I do not use JavaScript for form validation, I use php. But I do use JavaScript a lot for lots of things. I also have a web store (wanna a cookie anyone?) that requires that JavaScript be active, because I have to get data from the HTML page—ribbon color, quantity and the like.

First, are you confusing Java (developed by James Gosling at Sun Microsystems, bought by Oracle) with JavaScript (originally developed in Netscape, by Brendan Eich)? Gawd, I hope so.

Second, does this mean that my shopping cart will break with JavaScript disabled? Really, what I'm doing is just passing ribbon and other cart information to php using ajax.

Mind you, there's no form validation here, just looking at quantities of what we have picked, ribbon color and putting information on the page that indicates to the user that they have XX items in their cart at the present time, based on their session ID.

The Java coding language is an entirely different animal from Javascript.

Java has been the recently vulnerable technology

Ooooops, just noticed thi has already been addressed by mhollis

My bad

When you can create a fully-functioning menu with drop-downs (and overs) using CSS like this one, I do not recommend using JavaScript for menus.

That was the result of a "pure CSS drop-down menu" search using Google.

Project 7 is using JavaScript in Pop Menu Magic 2 and Tree Menu Magic 2 as well. There's animation in these two menuing systems. For non-drop-down menus, Project 7 uses JavaScript for Menu Bar Magic animations (and I quite like those). I don't know how PMM2 and TMM 2 menuing degrades without JavaScript. Good Question for Al Sparber, who does participate here. For MBM animations, they "degrade" quite nicely, as a rollover won't cause any animation, but it won't cause the menu to disappear, either.

 

Nancy, you have me really worried. I use more and more JavaScript these days and HTML5 seems to be pointing the way for even more. I want my websites to be dymanic and look cool. I'm not sure what a future without JavaScript would look like.

 

In this day and age, "browsers with script disabled" is pretty much statistically irrelevant. That said, the latest versions of all of our menu products are fully accessible with script disabled. PMM2 reverts to a pure CSS menus and the drop-downs actually work. Tree Men uMagic simply expands to fully show all of the links, which is how our widgets behave. There is no problem.

The issue of forms handling is a problem. Validation should be done with server-side scripting in PHP or a similar language and not via client-side JavaScript. Typically, though, it is not a fatal problem as most people forced to browse at work with constrained systems should not be browsing your site anyway. They should be working. If they need to access one of your client's sites (likely for personal reasons) they will likely be very comfrotable with waiting until they leave the office. Understand too, that the major social media sites, like Facebook, will not even allow you to log in unless JavaScript is enabled.

To test your page with script disabled, simply use the developer tools that come with Chrome or IE9/10 and toggle script off.
