Form Submission With No Way to Identify What Went Wrong

3.3.1 — Error Identification

Scenario

Setting

A calendar app's event-creation form

What’s wrong

No numbered W3C failure technique exists for this rule — it fails simply when the required feature/behavior is missing or inadequate (see the scenarios below).

Example

A calendar app's event-creation form runs into this exact issue: no numbered W3C failure technique exists for this rule — it fails simply when the required feature/behavior is missing or inadequate (see the scenarios below).

Why it matters

Everyone submitting forms — especially screen-reader and color-blind users who miss color-only cues. In this case (a calendar app's event-creation form), they have to guess at the correct format.

How to test

Submit a form with invalid data and check whether ANY error identification appears — visual, textual, or announced: absence of all three fails.

How to fix

A text error message must identify each field in error and be exposed to assistive technology (announced automatically or focused).

Outcome

Once corrected, a calendar app's event-creation form lets them complete the form without guessing.

Who is affected

Everyone submitting forms — especially screen-reader and color-blind users who miss color-only cues.
