Usually handing forms involves coding the form in HTML and performing client and server side validation, which usually makes the code for complex forms quite unwieldy. Zend_Form which is available in Zend Framework version 1.5 aims at simplifying this process.

With this new version comes the ability to add in methods for validation right into the form definition. His example shows a traditional login form that checks things like if it's required, checking the length and adding filters to modify the input.

I got a question in the comments about my previous post on simple user registration about how to do some of the necessary validation for registration in the model. I thought I'd show some code I did to do exactly that.

He includes the code for his example with the key, he explains, being the use of a second field (the confirm password field) to do the validation.
