Form Validation Javascript!

[stevesh]

in the similar vein, while making changes to create_account I was wondering why the form validation seems to be duplicated in both the php and in the javascript.

Yes, I'm pretty sure that's why it's duplicated. One of the things I like about Zencart is that it works in all browsers, regardless of the settings the visitor prefers.

Is it because we still supposed to be looking after people with javascript disabled?

Only if you want us as customers, I guess.

I looked up some stats and at last 6% have Javascript turned off, which is more than I would have thought and a significant number of customers!!

So to cater for all, one should duplicate the validation, which leads to thinking that although javascript is easily added to a page, unless you want double work in two (programming) languages any validation on extra fields is best done once in php and left at that.

Why add the extra javascript at all?

Or am I missing something, as is often the case...

Javascript is run client side whereas php requires you to send the information to the server first. For simple form validation it is often easier on the user and on the server to catch errors before the page is sent.

That being said javascript can easily be turned off and circumvented so PHP validation is a must.
