Form Plugin 8.1.0: Basic Captcha challenge type "Math Puzzle" doesn't work

1

After updating from Form 8.0.6 to version 8.1.0, the “Math Puzzle” challenge type no longer works.

After trying all possible settings without success, I was forced to revert to version 8.0.6.

Is this a known issue?

Is there a solution?

I read what was written about Issue #622. The problems described there concern version 8.0.6.

The crazy thing is: In Issue #622 ganakee writes, “… I was stuck in math puzzles rather than text …”.

For me, it’s the other way around: I can’t get away from “Random Characters,” even though I specify “Math Puzzle” in the settings.

@hjb, Your issue and the issue at Gitbut are both about the Math Puzzle. Andy says it has been fixed in 8.1.0, but according to you it’s not. Right?

Let Andy know by adding a comment with your version and your issue.

I’ve tested the latest 8.1.0 version quite extensively with math and chars with basic captcha and it works well.. What are your config options?

This is my ../user/config/plugins/form.yaml:

    text: '#000000'
  math:
    min: 1

    operators:
      - +
      - '-'

Note the type: math

The part concerning the captcha in form.md:

title: Anmeldung
process:
    markdown: true
    twig: true
form:
    fields:

...

        datenschutz:
            label: 'Die Datenschutzerklärung akzeptiere ich'
            type: checkbox
            validate:
                required: true
        basic-captcha:
            type: basic-captcha
            placeholder: 'Ergebnis der Rechenaufgabe...'
            label: 'Ich bin kein Roboter!'
            validate:
                required: true
    buttons:
        submit:
            type: submit
            value: senden
        reset:
            type: reset
            value: 'zurück setzen'
    process:
        basic-captcha:
            message: 'Bist Du wirklich kein Roboter?<br>Bitte versuche es noch einmal!'

And this is the result using form-8.1.0:

screenshot-math-8.1.0
screenshot-math-8.1.0537×226 17.7 KB

If I use the same settings with version 8.0.6, the result is

screenshot-math-8.0.6
screenshot-math-8.0.6792×205 13.7 KB

With version 8.0.6, both variants “math” and “characters” are rendered correctly. 8.1.0 always displays the character variant regardless of which “type” is set.

I’ve observed this problem on three different sites. All sites are running Grav v1.7.50.3 with different themes: Quark, Helium, and Typhoon.

What is wrong here?
