Hi sandra-ch,

When your form is submitted with a blank capture code it is still being accepted. Also with wrong input to captch request. I dont think your captcha is working at all.

In fact, I can see that you have switched off the captha code setting to access your manager. That is why the captcha result of 'false' is being ignored. Just switch it on from the configuration panels (cant remember which panel - sorry).

Hope this helps,

Paul.

Captcha needs to be implemented in 2 ways..1) to show the code, 2) to validate the code. See the documentation for the 2 calls that can be used together:

Quote

getCaptchaNumber($length, $alt='Captcha Number', $title='Security Code')

// returns a Captcha Number image to caller and stores value in $_SESSION['captchNumber']
// $length = number of digits to return
// $alt = alternate text if image cannot be displayed
// $title = message to display for onhover event
validCaptchaNumber($number)

// returns Captcha Number validation back to caller - boolean (true|false)
// $number = number entered by user for validation (example: $_POST['captchaNumber'])

Also, if you want to see an example of how this was implemented, you can refer to the etComment snippet that has it integrated:

//Initiate Captcha
 if($useCaptcha == true && isset($_POST['captchaCode']))
 {
	$captchaEntry=htmlentities($_POST['captchaCode']);
 
	if(!$etomite->validCaptchaCode($captchaEntry)) { 
	   $captchaError = true;
	   $errorsOut .=$text['NotValidCaptcha']."<br />";
	   }
 }

if($useCaptcha){
$formArr['captchaInput']='<input type="text" name="captchaCode" />';
$formArr['CaptchaMessage'] = $text['CaptchaMessage'];
$formArr['captcha'] = $etomite->getCaptchaCode();
}

$formChunk .= $etomite->parseChunk($etoCommentForm, $formArr, '{', '}');

If this is too tricky for you to adapt to Guestbook, Ralph may assist.

Edited to fix code block nesting.

The site in question was already fixed before sandra-ch made her last post... CAPTCHA is working... Any remaining issues are related to dated snippet code which could be totally re-written... There is a remote possibility that I may release a new snippet that stores messages in the user_messages table... I started the code yesterday after discovering how old the GuestBook snippets are getting...
