Form-Field Validation: The Errors-Only form error messages html Approach By Christian Holst June 27th, 2012 FormsInteraction DesignUsability 49 Comments 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 examples of good error messages page. We also noticed that test subjects who had been exposed to validation errors began to take preventive actions to avoid them in subsequent steps, by writing things such as “N/A” in the “Company name” field if in doubt about whether the field was optional. 1 When getting the exact same page but with an error message, the user will feel they have made little or no progress, despite having typed 90% of the form fields correctly. (Image: Blue Nile2) Some of the frustration with validation error pages likely stems from the user being returned to the same page they came from. Being returned to the exact same page is problematic for a couple of reasons: With all form fields still displayed (valid or not), the user might have difficulty identifying the few erroneous fields among the many valid ones. More critically, seeing the same page twice makes it seem like the user has made no progress, despite having just filled in numerous form fields correctly.

However, people often make mistakes. This is where web form validation comes into play. The goal of web form validation is to ensure that the user provided necessary and properly formatted information needed to successfully complete an operation. In this article we will go beyond the validation itself and explore different validation and error feedback techniques, methods and approaches. Validation methods Link User's input can be validated on the server and on the client (web browser). Thus we have server-side and client-side validation. We'll discuss pros and cons of each. Server-side validation Link In the server-side validation, information is being sent to the server and validated using one of server-side languages. If the validation fails, the response is then sent back to the client, page that contains the web form is refreshed and a feedback is shown. This method is secure because it w

How you can help. While you should always validate data on your servers, additional validation of data on the Web page itself has multiple benefits. In many ways, users are annoyed by forms. By validating form data while the user is filling it out, the user can know immediately if they've made any mistakes; this saves the time of waiting for an HTTP response and saves your server from dealing with bad form input. This article covers how to validate form data within your form's Web content. Using browser-supplied form validation One of the features of HTML5 is the ability to validate most user data without relying on scripts. This is done using validation attributes on form elements. When an element is invalid When an element is invalid, two things occur: The element matches the :invalid CSS pseudo-class; thi
