Adding an ImageVerification captcha / anti-spam check
One of the most common features of forms are "Captcha" checks, which try and verify that the submitter is not a "spambot". There's a constant battle to try to keep out the spammers without blocking legitimate users.
ChronoForms has a built-in "imageverification Captcha check" and, as we'll see in the next recipe, there is also an option to use an external check instead.
Getting ready
As usual, we're going to add this to the newsletter form.
How to do it...
1. This is a two-step process — first we will add a "place-holder" to the Form HTML using the Wizard Edit, then we'll enable it in the Form Editor.
Open the form using Wizard Edit, drag across a "Captcha" element, set the Label text in the Properties box, and click Apply to save it. Save the form and return to the Forms Manager.
Note
If you prefer to edit the Form HTML directly, then you need to make sure that the
{imageverification}placeholder is included where you want the Captcha check...
