Hello,
I'm a total newbie with RSForm Pro! and I have trying to find the best way to create anti-spam filters and i was wondering if there is a way to make the following:
- Add an form field and hide it with CSS and if the field is being filled out, the form doesn't submit and sends to an error page.
- Add a question like: "Are you human? 2+2=" and the user needs to fillout "4". If the answer is not right, the user is sent to an error page

I know about the "invisible" option from the built-in captcha system.

Any help or guide will be great.

Thanks for your time.

Hello,

1. The best regarding for what are you trying to do is to create a invisible CAPTCHA.The result will be similar to what you are trying to accomplish.

2.You can read the documentation here:

For example you can try this:

Sorry to bump this thread..

But I can't make it work, nothing happens at submit. No email is send, even if the answer is correct. There to put the code?

Joomla 2.5.7
RSform!Pro 1.4.0 rev 44

The easiest way is to use the default hidden captcha anti-spam option. You should do the following:

- Add a new form field of type CAPTCHA Antispam.
- Name your field something like "Comment" or "Question".
- Leave the Caption field empty.
- Go to the Attributes tab.
- For Image Generation choose "Invisible".
- Save the field.

Now your form has a new hidden form field. Normal website visitors will not see the field and leave it empty. Spambots might see the field and insert some content in it. The form will then not validate and will not be sent.

Good luck!

The invisible captcha don't work for me, I receive a lot o spam.

I'm very sorry to bump up a 3 year old topic but my question is legitimate.
I usually use the No reCAPTCHA but in some situations where I put the form within a NoNumber slider (accordion menu type) to hide the form unless the user wants to file it, the No reCAPTCHA does not validate.

So instead, I've setup the form with the invisible CAPTCHA methode like renekreijveld mentioned and the form gets sent.

Now my question is,,, can someone confirm to me if that invisible CAPTCHA method is really working today with the latest version of RSForm PRO?

I wouldn't want my client to get buried in SPAM mail.

Thanks in advance four your help.

Best regards,

Denis.

Any news for my question? Please?

There is no such thing as bulletproof spam prevention methods. There some that perform better then others. The invisible captcha method does its job and prevents spam submissions.
