Forms

Guidelines

• Render FlashMessage on success
• Handling errors/validation messages:
  • Render API errors using a <MessageError> or Hds::Alert at the top of forms
  • Display validation error messages onsubmit (not onchange for inputs)
  • Render an <AlertInline> beside form buttons, especially if the error banner is hidden from view (long forms). Message options:
    • The invalidFormMessage from a model's validate() method that includes an error count
    • Generic message for API errors or forms without model validations: 'There was an error submitting this form.'
  • Add has-error-border class to invalid inputs
