I have a question on Captcha. I would like to change the font color of the random questions that are asked to white? I would like to know what code to write and where to place it.

Here is the code:

<?PHP

class FGSimpleCaptcha extends FG_CaptchaHandler
{
var $error_str;
var $captcha_varname;
var $uniquekey;

function FGSimpleCaptcha($captcha_var_name)
{
$this->captcha_varname=$captcha_var_name;
$this->uniquekey='KHJhsjsy65HGbsmnd';
}

/*Add more simple questions here.*/
function GetSimpleCaptcha()
{
$arrQuestions = array(
"What color is the sky?"=>"blue",
"What is 1+1?" => "2",
"What is the color of grass?"=>"green",
"Are you a robot?"=>"no",
"Are you human?"=>"yes");

$question = array_rand($arrQuestions);
$answer = $arrQuestions[$question];

$_SESSION['FGCF_Captcha_Answer'] = $this->Md5CaptchaAnswer($answer);

return $question;
}

function SetFormKey($key)
{
$this->uniquekey = $key;
}
function GetKey()
{
return $this->uniquekey;
}
function Validate()
{
$ret=false;
if(empty($_POST[$this->captcha_varname]))
{
$this->error_str = "Please answer the anti-spam question";
$ret = false;
}
else
{

$scaptcha = trim($_POST[$this->captcha_varname]);

$scaptcha = strtolower($scaptcha);

$user_answer = $this->Md5CaptchaAnswer($scaptcha);

if($user_answer != $_SESSION['FGCF_Captcha_Answer'])
{
$this->error_str = "Failed the anti-spam check!";
$ret = false;
}
else
{
$ret = true;
}
}//else
return $ret;
}
function Md5CaptchaAnswer($answer)
{
return md5($this->GetKey().$answer);
}
function GetError()
{
return $this->error_str;
}
}
?>

you would change the font color of the random questions by using CSS on the page where the random question is displayed.


<span style="color: red;"><display random question></span>

Thanks, Jason! Worked like a charm. Sometimes the solution turns out to be easier than first perceived.
