Error pages for form-field validation are dreadful. You’ve just filled out 20 form fields, yet you get the same bloated page thrown back in your face because a single field failed to validate. I clearly recall the often loud sighs of despair during our last usability study each time a test subject encountered a validation error page.
We reflected on this problem and got an idea that we call “error fields only” — which is exactly what this article is about. Before exploring this idea, let’s look at three traditional types of validation techniques: “same page reload,” “optimized same page reload” and “live inline validation.” http://sswi.me/LSVWs1 via @smashingmag
