File Selection That Auto-Submits the Form With No Warning
3.2.2 — On Input
Scenario
Setting
A car-rental site's checkout flow
What’s wrong
File input auto-submitting on selection with no advisement.
Example
On a car-rental site's checkout flow, a visitor hits this wall: file input auto-submitting on selection with no advisement.
Why it matters
Keyboard and screen-reader users, and people who need predictable form behavior. Here, on a car-rental site's checkout flow, the result is they have to relearn the layout on every page.
How to test
Select a file in a file input: if the form auto-submits on selection with no prior advisement, it fails.
How to fix
Changing a field's value must not navigate, submit, close, or change context unless the user was told beforehand or explicitly confirms.
Outcome
After the fix, the same visitor to a car-rental site's checkout flow can now move confidently between pages.
Who is affected
Keyboard and screen-reader users, and people who need predictable form behavior.
