Simple HTML form for coupon codes?

[SMedia]

I'm trying to set up a VERY simple form box for a single coupon code.

Is it possible to send a user to a different page when they enter a specific code?

Nothing fancy, as there will be only one code that works.

For example, customer enters "XYZ" in the box, hit's submit, and get's sent to a discounted version of the product.

If they enter the wrong code, they get redirected to a different page.

Is this possible in HTML only?

Welcome to the forums, SMedia.

No, that's not something you can do with HTML alone. It's going to take scripting of some flavor or other. The script will run either server-side (most likely) or possibly client-side (like javascript) if the number of possibilities are minimal and not changing very frequently.

If you run it client-side, I can get to your discounted version.

Of course it is possible to work around any client side coding, how javascript savvy are your visitors likely to be? Its a risk that you must consider if going for JS but most web users (and a significant number of amature webmasters) don't even understand that the source code exists.
