Usage

We have it prepared to be setup in an Horizontal or Vertical way (css changes and the number of images showing). Type 0 is Horizontal and 1 is Vertical. By default, Horizontal is applied, so if you want to show it vertically, you can use:

printCaptcha('frm_sample',1);

Overview

Captcha is a great thing, it makes it more difficult (hopefully impossible) for bots to submit forms "blindly", creating/sending junk to mails/databases.

However, through time, we've become more and more aware it doesn't work as expected. It difficults communication, and as such, people make mistakes often in the common Captcha forms, making it sometimes a reason for giving up filling a form (specially when the form is big and it doesn't refill the sent information).

So, we thought: "wouldn't it be great to find a way to make a Captcha work better for humans and still be impossible to be submitted automatically by bots?"

We found a great concept for this answer at Ajax Fancy Captcha - jQuery Plugin, but also found in it a few bugs and easy ways for bots to "learn" how to bypass it. As there was nothing really good and innovative as we wanted it, we built our own!

    I would like to use it in a project but I need to show it working in live sites. Could you provide a few examples of sites already using it please? Thanks

      Hi, Sergio. Because visualCaptcha is self-hosted, we don't have a way to track who's using it and where, only the donations we get, number of downloads, and messages saying they loved visualCaptcha, as a way to measure. Sorry!

    I created a function called function_captcha which allows me show and validate the CAPTCHA from anywhere but it doesn't validate the form even if I drag the correct image. It however works if I use the accessibility option, further testing showed that the variable fieldname isn't set, how do I use it? Can't even find it in your demo.

      Hi, Love. It seems like the normal variable might be being overwritten by something else, but that's strange. Can you open a ticket with a few more details (including HTML and PHP code)?
    • L Love 2 years ago
      Okay. From your demo, your form contains an array CAPTCHA-VALUE, mine does not. Thanks.
