contact form

It depends on what sorts of fields you want to validate, in general you can:

• Mix HTML5 input patterns with a JQuery fallback
• Combine that with server-side PHP
• Add in a healthy dose of regex
• Stir and served chilled.

As James says make sure you validate server sde, this is a must since JS can be turned off in the browser so you can't rely on that alone.

I've used the following jquery plugin which is good http://bassistance.de/jquery-plugins/jquery-plugin-validation/

HTML5 has brought some great new features, cool keyboard changes on smartphones etc

Hey Israel,

James has it right. We have some content online in the latest projects that discuss this. Andrew talks about jQuery validation here:

• jQuery: Form Validation and Manipulation

I talk about creating the form and doing basic server-side validation in PHP here ...

• PHP: Adding A Contact Form

... and then how to handle some more advanced server-side validation and send the email here ...
