MODx (Revolution) - using CAPTCHA extra for forms

I have installed CAPTCHA extra on MODx Revolution. According to its description

"The Captcha components can also be used by other components to create captcha-style verification for front-end forms."

When changing captcha.enabled in System setting to Yes, it adds Captcha to manager login, but there's no documentation on how to use it on other components, neither I could find any example by googling.

How can I use the Captcha on a desired form? (and not on manager login if possible)

Thanks for your time.

Solution

  • You add it somewhere in your form where you want it to appear:

    <img src="[[++assets_url]]components/captcha/captcha.php" alt="Captcha Image" />

    And create a textfield for user to enter the result. Then wherever you're doing the validation for your form, compare the value of the textfield to $_SESSION['veriword'].
