Errors occur when an app fails to complete an action, such as:The app does not understand user inputThe system or app failsA user intends to run incompatible operations concurrentlyMinimize errors by designing apps that make it easy for users to input information flexibly. Apps should accept common data formats that use affordances to improve user understanding.

Web Form Validation: Best Practices and Tutorials By Janko Jovanovic July 7th, 2009 CaptchaFormsValidation 73 Comments Ideally, users will fill the web form with necessary information and finish their job successfully. 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 https://www.smashingmagazine.com/2009/07/web-form-validation-best-practices-and-tutorials/ 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 will work even if JavaScript is turned off in the browser and it can't be easily bypassed by malicious users. On the other hand, users will have to fill in the information without getting a response until they submit the form. This results in a slow response from the server. The exception is validation using Ajax. Ajax calls to the server can validate as you type and provide immediate feed
invalid formats), the form displays validation error messages. This post describes how you can customize the validation error messages http://contactform7.com/customizing-validation-error-messages/ that Contact Form 7 produces. Changing Text You can change the text used in each type of error message. For example, the default message for required fields is http://ux.stackexchange.com/questions/26173/what-is-best-practice-for-designing-form-error-messages "Please fill the required field." To change this message, go to the admin page and edit the text in the Messages section. Static or Floating-tip You have error messages two different style options for validation error messages: static and floating-tip. Static is the current default option. Floating-tip was once the default option in Ajax submission mode before Contact Form 7 3.6 demoted it because of poor accessibility. Look at these demo forms to see the differences between the two styles. Static style Lorem form error messages ipsum dolor sit amet, adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea consequat. Floating-tip style Lorem ipsum dolor sit amet, adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea consequat. Each style has advantages and disadvantages. Advantage Disadvantage Static style (default) Good accessibility Same behavior in Ajax and non-Ajax submission modes Possible to break the layout when used for inline fields Floating-tip style Not possible to break the layout even when used for inline fields Poor accessibility Only works in Ajax submission mode Normally, static style is recommended as it causes less accessibility issues. However, if you have inline fields in a form and inserting static error message blocks after them breaks the form layout, using floating-tip style is the better option. Sw

The only piece of advice seems to be that each error should clearly be associated with the invalid form field that it aims to correct. Has there been any research on this? I have some specific issues I'm trying to work through and would appreciate any insight or resources. Error message location When you have live form validation, where should an error (or success) message appear in relation to the form element? Some options: To the right of the input download bmml source – Wireframes created with Balsamiq Mockups To the right of the label download bmml source Above the label download bmml source Below the label download bmml source Below the input download bmml source There are some thorny issues that also need to be taken into account regarding location: How are errors displayed for radio or checkbox groups? How wide is the error message? Is the error message multi-line? Error message visibility Besides location, I'm also interested in how the visibility of the error message affects its usability. Does it matter or is it strictly a aesthetic decision? Consider the following 3 options: download bmml source Edit: There have been some excellent points on accessibility in some of the answers so far, as well as some interesting examples. However, I really would like to see some data from actual studies, if possible. Also, none of the answers so far have really addressed the two questions I had above: Where should the error be located in relation to the input and label? How does the design and visibility of the error message itself affect its usability? Regarding the accessibility of the forms, it seems to me as if there might be two potentially conflicting use cases, live validation and server-side validation (wh
