What may seem obvious to the author of a form may be much less so for its users: help them whenever possible.

Goal

  • Help users understand what is expected and, by doing so, facilitate their progression to the next step.
  • Prevent user frustration in the face of mistakes for which they don’t have an immediate solution.
  • Improve the accessibility of content for people with disabilities.

Implementation

For each field containing rejected data, indicate the nature of the error and provide correction help

  • Either at the start of the form, in a list of incorrect fields;
  • Or in the context of each field, as much as possible using itslabel label.

Control

For each form checked:

  • Check for the various possible errors in each form - no input in a field, non-compliance with a requested or predictable format (format of email address, date, etc.), case sensitivity, etc.
  • If the input is rejected, check that the nature of the error is specified to help in its correction, by one of the means indicated in the implementation paragraph.
