[NSFW] Validation returns always false.

Hello,

I am fighting with this from one hour and still I can not fix it. So I have to ask you for help. I hope I can count on you!

So, I created fields, image and the result is:

View post on imgur.com

HTML:

To validate my code is in different function:

$value = $_POST['code_captcha'];
$captcha = new ReallySimpleCaptcha();
if($captcha->check( $_POST['captcha_prefix'], $value ) == false){
return $error;
}

Before I wrote this psot I checked if there is genereted a new captcha during validation – no, is not. The validation still using old “prefix” and “answer” ($value). I checked also sent requests to “check” – they are still the same as in the form.

I do not know how to fix it. I tried already almost every thing… but it still does not work. Could you help me with it?

Thank you in advance!
