Error suggestions messing on form inputs "Handyankauf"
Priority: Moderate Low Page: iPhone Erleben Observation Permalink

Observation Details

Handyankauf form input throws errors but known suggestions are not made.

  • Step 2: "IMEI ungültig" does not hint to specific format requirements (e.g. number of characters, as shown in label, omitting spaces, etc.)

  • Step 5: "Code/IMEI-Nummer ungültig." does not suggest Code/IMEI format requirements (compared to e.g. step 2)

  • Step 5: "Achten Sie genau auf die Buchstaben oder Nummern." is not accurate wording for input of IMEI number

  • Step 6:

    • "Der Vorname ist ungültig."

    • "Der Nachname ist ungültig."

    • "Die IBAN ist ungültig"

Remediation Notes

Ensure, all known error suggestions are displayed in error message or visible label.

Especially when arbitrary requirements are implemented (length minimum on "Vorname" and "Nachname"), display the requirements in the error message. Side note: setting these arbitrary requirements will exclude people.

Observation Details

Error messages merely duplicate label content ("Vorname" → "Bitte geben Sie Ihren Vornamen ein."). Error messages must inform the user about the error, not about existing information.

Remediation Notes

Instead of repeating label content, explain the actual errors to the user, so the user is helped with solving the issue at hand. This means, using error messages like:

  • "Dieses Feld darf nicht leer sein."

  • "Die E-Mail-Adresse enthält kein @ Symbol"

  • ...

Repetition of label content is not necessary, as the errored input label will still be announced to assistive technology. Repeating label content will only duplicate announcement. Navigating to an errored input via assistive technology will announce the label and the description (error message).
