Custom form - Submission fails

Is the console showing any JS errors when you are on the form page?

Did you try reinstalling the module, the issue goes away for most of the users after that.

@guardian87 Thanks for sharing this information. I will keep this issue open and use it for improving the documentation.

Had the same issue when updated to 1.5, happened on a custom form with field by field basis. Adding form.antibot_no_js didn't solved it.

For now I have to go back using 1.4

I will take a look at it.

What I mentioned in #9 isn't a problem anymore. I assume it had something to do with another module. My apologies!

I'm facing the same issue on a custom user registration form. Was working fine until the v1.5 upgrade, so I've downgraded back to v1.4 for the time being. Drupal 9.3.2, PHP 7.4.25

I'm including the antibot key in a twig template called "form.html.twig" like so:

{% block form %}
  <form{{ attributes }}>
    {{ element['antibot_key'] }}
    {{ children }}
  </form>
{% endblock %}

I had this issue again recently and I noticed that I had printed the {{ attributes }} twice in the same twig template #facepalm, so I thought to post this here as well in case anyone did something the same as me.

Antibot Module version: 2.0.2
Drupal Version: 9.3.12

I had custom Webforms that weren't working on a site with the Antibot module enabled and protection enabled in the Webforms settings. Once I included {{ element.antibot_no_js }}{{ element.antibot_key }} in the form Twig template, everything worked fine. I only needed to include it once in the template and I did so at the very bottom with some of the other hidden fields like form_token and form_id. This bit of information is no where in the documentation unless I missed it somewhere. Preferably, the module page and the README file. Here is what my block looks like the the bottom of the webform Twig template:

            <div class="row">
                <div class="col-md-2 offset-md-1 offset-lg-2">
                    {{ element.elements.message }}
                    {{ element.elements.url_redirection }}
                    {{ element.form_build_id }}
                    {{ element.form_token }}
                    {{ element.form_id }}
                    {{ element.elements.actions }}
                    # Antibot keys to render.
                    {{ element.antibot_no_js }}
                    {{ element.antibot_key }}
                </div>
            </div>
        </div>
</form>

#18 Worked for my custom forms! Thank you very much jumpsuitgreen! Pretty incredible that this solution was posted at the exact time as I was having the problem.

form_id was returning null or empty when executing form validation logic.
This code _antibot_generate_key($form['#form_id']); in antibot.module

Changed to
_antibot_generate_key($form_state->getValue('form_id'));
Now the form_id is returning the correct value and the form is processed with no antibot related errors.

I included the instructions for the fix from #18 in the README.md file in this MR.

Can be reviewed anytime.

I'll merge this, it's just documentation changes.

Thank you everyone.
