You busted me, Amanda! I do wish I had time to do better form validation and to integrate it into WordPress. I especially like the <a href="http://labs.adobe.com/technologies/spry/" rel="nofollow">Adobe Spry</a> validation framework and would love to see someone integrate the two! Thanks! (And I always appreciate that there are multiple opinions on any topic). Doug Doh! You busted me, Amanda! I do wish I had time to do better form validation and to integrate it into WordPress.

I realise that you're using Wordpress to blog your thoughts onto the internet, but perhaps ensuring that you practice what you preach isn't such a bad idea either. :) Good post, by the way, even if I don't necessarily agree with all you've written.

And its lazy to just post a message that its wrong, when you can fix it without having to guess at the format. However, I also agree with Nicolas about using Server Side logic in conjunction with AJAX.

Some forms look fine, but it doesn't offer good validation. Personal information are given and it's only proper to take it seriously just like any business forms in hard copy. I agree with you.

However, it is more important to make sure that the validations themselves actually make sense. You provided a brilliant example of how validation can mislead users and, worse, drive them away from our site: Geek Wisdom's password strength validation from considers <em>tZhKwnUmIss</em> to be a weak password. Not only is this a perfectly strong password but it will also alienate users because it gives them the false impression that logging into your site using this password will be somehow insecure. It would be much better (and easier) to simply hint users that a good password is at least six characters long and should contain both numbers and letters. Other questionable validations include user names that need a certain minimum length or may not contain spaces. What's wrong with the usernames <em>X</em>, <em>john doe</em>, or even <em>#*!§</em>? I can handle that. I agree that client validation can be a very user friendly feature. However, it is more important to make sure that the validations themselves actually make sense.

Passwords are really important and must be taken seriously. I think it's only normal for almost all form to type the password twice, but not showing the validity of the two passwords shows that it's not being considered seriously. I agree.

As a team lead, I usually find myself sending code back to be "finished" for reasons such as missing validations or restricting text input lengths. For most things I work on I find it takes about 50% of the time to get something working, under normal conditions and if users use the system the way I intended. The other 50% of the development time comes from checking their input, ensuring data integrity is maintained, and making the form fields not allow malicious data to be entered. I wrote a post on how I use InputVerifiers in my hava swing apps, and show how I verify an email text field. The regular expression I use is easily modifiable to validate phone numbers, zipcodes, SSNs, etc. My blog post is at <a href="http://timarcher.com/?q=node/36" rel="nofollow">http://timarcher.com/?q=node/36</a> Good writeup Doug!
