TCaptchaValidator class TCaptchaValidator validates user input against a CAPTCHA represented by a TCaptcha control. The input control fails validation if its value is not the same as the token displayed in CAPTCHA. Note, if the user does not enter any thing, it is still considered as failing the validation. To use TCaptchaValidator, specify the ControlToValidate to be the ID path of the input control (usually a TTextBox control}. Also specify the CaptchaControl to be the ID path of the CAPTCHA control that the user input should be compared with. Since: 3.1.1 Author: Qiang Xue <qiang.xue@gmail.com>

Output
boolean | whether the validation succeeds
Exception
## findCaptchaControl
protected TCaptchaControl findCaptchaControl | ()
Output
TCaptchaControl | the CAPTCHA control to be validated against
Exception
throws | TConfigurationException if the CAPTCHA cannot be found according to CaptchaControl
## getCaptchaControl
public string getCaptchaControl | ()
Output
string | the ID path of the CAPTCHA control to validate
Exception
## getClientClassName
protected string getClientClassName | ()
Gets the name of the javascript class responsible for performing validation for this control. This method overrides the parent implementation.
Output
string | the javascript class name
Exception
## getClientScriptOptions
protected array getClientScriptOptions | ()
Returns an array of javascript validator options.
Output
array | javascript validator options.
Exception
## setCaptchaControl
public void setCaptchaControl | (string $value )
Sets the ID path of the CAPTCHA control to validate. The ID path is the dot-connected IDs of the controls reaching from the validator's naming container to the target control.
