The captcha helper lets you integrate an image-based captcha into your forms, to help prevent spam. Uses the third party SecureImage library.
Loading the Helper
$captcha = Loader::helper('validation/captcha');
Displays a dynamically generated image, for use with the captcha input text field.
Creates the text field for that instance of the captcha. This text input element automatically has the name "ccmCaptchaCode"
$captcha->check($field = 'ccmCaptchaCode')
Automatically checks the request array for the passed $field. Returns true if the field contains the same text as the current instance of the captcha, false if the captcha has been failed.
