need to add a form field to determine if user is human

webguync · December 4, 2010

Hi,

I want to add another form field to determine if a user is human and not spam bots. I looked into CAPTCHA, but I think those are annoying. I was thinking about just having the user enter (5+5) and if the answer is not ten, then displaying a incorrect value message. If correct submit form and info to the Database. Not sure how to do that with what I currently have coded though so need some help with that part. Here is the current code.

				<?PHP
require_once "formvalidator.php";
$show_form=true;
if(isset($_POST['Submit']))
{
   $validator = new FormValidator();
    $validator->addValidation("FirstName","req","Please fill in FirstName");
$validator->addValidation("LastName","req","Please fill in LastName");
$validator->addValidation("UserName","req","Please fill in UserName");
$validator->addValidation("Password","req","Please fill in a Password");
$validator->addValidation("Password2","req","Please re-enter your password");
$validator->addValidation("Password2","eqelmnt=Password","Your passwords do not match!");
    $validator->addValidation("email","email","The input for Email should be a valid email value");
    $validator->addValidation("email","req","Please fill in Email");
$validator->addValidation("Zip","req","Please fill in your Zip Code");
$validator->addValidation("Security","req","Please fill in your Security Question");
$validator->addValidation("Security2","req","Please fill in your Security Answer");

    if($validator->ValidateForm())
    {
        $con = mysql_connect("localhost","beatthis","Jim2Drew!") or die('Could not connect: ' . mysql_error());

        mysql_select_db("beatthis_beatthis") or die(mysql_error());





$FirstName=mysql_real_escape_string($_POST['FirstName']); //This value has to be the same as in the HTML form file

$LastName=mysql_real_escape_string($_POST['LastName']); //This value has to be the same as in the HTML form file

$UserName=mysql_real_escape_string($_POST['UserName']); //This value has to be the same as in the HTML form file

$Password= md5($_POST['Password']); //This value has to be the same as in the HTML form file

$Password2= md5($_POST['Password2']); //This value has to be the same as in the HTML form file

$email=mysql_real_escape_string($_POST['email']); //This value has to be the same as in the HTML form file

$Zip=mysql_real_escape_string($_POST['Zip']); //This value has to be the same as in the HTML form file

$Birthday=mysql_real_escape_string($_POST['Birthday']); //This value has to be the same as in the HTML form file

$Security=mysql_real_escape_string($_POST['Security']); //This value has to be the same as in the HTML form file

$Security2=mysql_real_escape_string($_POST['Security2']); //This value has to be the same as in the HTML form file



$sql="INSERT INTO Profile (`FirstName`,`LastName`,`Username`,`Password`,`Password2`,`email`,`Zip`,`Birthday`,`Security`,`Security2`) VALUES ('$FirstName','$LastName','$UserName','$Password','$Password2','$email','$Zip','$Birthday','$Security','$Security2')"; 
//echo $sql;

if (!mysql_query($sql,$con)) {

die('Error: ' . mysql_error());

}



else{



mail('[email protected]','A profile has been submitted!',$FirstName.' has submitted their profile',$body);

echo "<h3>Your profile information has been submitted successfully.</h3>";

  



}

mysql_close($con);

        $show_form=false;
    }
    else
    {
        echo "<h3 class='ErrorTitle'>Validation Errors:</h3>";

        $error_hash = $validator->GetErrors();
        foreach($error_hash as $inpname => $inp_err)
        {
            echo "<p class='errors'>$inpname : $inp_err</p>\n";
        }

I'm not sure if it was a good idea for me to use a session though - I never really use them.

thanks, I get the error msg. though even if I type in the correct value. How can I debug why this is happening?

Zero3X · December 5, 2010

I think I fixed it. Basically $human_answer was being set again when the form was submitted - so if the question was 3 + 7 and you wrote 10 when the form was submitted the question would change to 23 + 12 or something stupid. My bad. ANyway this should fix it. I also replaced the die() functions with echos.

<?PHP
session_start();
require_once "formvalidator.php";
$show_form=true;

if (!isset($_POST['Submit'])) {
$human_number1 = rand(1, 12);
$human_number2 = rand(1, 38);
$human_answer = $human_number1 + $human_number2;
$_SESSION['check_answer'] = $human_answer;
}

if(isset($_POST['Submit']))
{



if (!isset($_SESSION['check_answer'])) {
echo "<p>Error: Answer session not set</p>";
}


if($_POST['math'] != $_SESSION['check_answer']) {
echo "<p>You did not pass the human check.</p>";
}

thanks, still a problem though. The form submits even if the value is wrong in the math field.

Zero3X · December 5, 2010

Ah! Sorry, I'm quite tired.

Add

exit();

after

echo "<p>You did not pass the human check.</p>";

webguync · December 5, 2010

thanks. Seems to work now. One other thing I need help with in regards to this. Is there a way to display the form if there is an error with the human check? Right now the error displays, but no form.

need to add a form field to determine if user is human
