Drawing on three years daily experience using ChronoForms and supporting users there is valuable help for new users and experienced developers alike. We will take you through form development step by step: from creating your first form using ChronoForms’ built-in drag-and-drop tool; validating user input; emailing the results; saving data in the database, showing the form in your Joomla! site and much more.Each chapter addresses a topic like ‘validation’ or ‘email’ and the recipes in the chapter each address a different user question from the beginners’ question ‘How do I set up an email?’ through to more advanced questions like using some PHP to create a custom email Subject line.Over eight chapters and eighty recipes we cover all of the ‘Frequently Asked Questions’ that new users and developers have about using ChronoForms.

Preface

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. 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...
