• try clicking on the submit button without filling the form and then, as you fill the form, to see the JavaScript validation in action
• for each example, notice how the PHP code of the form remains basically unchanged, despite the template variations
• disable JavaScript to see the server-side validation in action
• although in all my examples I use HTML output, you can switch to XHTML output by using the doctye method
• try the example in another browser and see that it works, out of the box. including IE6!
