Protect the script.

Let's see if I've got this straight......

OK...I've created a form using Dreamweaver...(typical delivery/billing form).
Now I hear that if I use Javascript to validate a form on a dynamic site, server side, a user could alter the Javascript and therefore alter the form. How can I avoid this?

edit the javascript...i think you may be lost here.
Using javascript for validating forms is good, however it can be turned off, meaning bad information can be passed into the prossesing....i think thats what you meant.

you should use server side validation aswell (for example in asp ..... if request.form("name") = "" then etc etc )
what language are you using to prosess the form,we can help you out better then.

Thanks for the advice. I'm still unclear on some aspects of
server-side script/Javascript.

If Javascript can be turned off I don't understand the point of using it.
You're right I'm a bit lost. (got no formal teaching, just picking up knowledge off the web and "Sams" self-teach books).
Does this mean that a shopping cart, for instance, should only validate using PHP or asp or Perl etc. server side?
I plan to process the form using PHP.

A good point - it can be turned off for security reasons. with javascript being client side you should not rely on just javascript to validate your forms. PHP (as you said you were using it) should be the basic way of validation, javascript would be a nice plus side. When using javascript for elements such as those, you allways need somthing to fall back on.

:wink: hope tht helps
