Hi I've tried adding a recaptcha for my register page.  For some reason it doesn't register , it also does't do recap check properly here is the code:  any ideas?

 

 

<html>

<head>

<link rel="stylesheet" type="text/css" href="./css/page.css" />

<br>Be sure to use only lowercase letters for account for account.<br />

</head>

 

<body>

<table

 

<?php

                    # Get the reCAPTCHA library

                    require_once('recaptchalib.php');

 

                    # These are /not/ real keys - you must replace them with your *own* keys

                    # obtained from http://recaptcha.net/api/getkey

                    define('PUBLIC_KEY',  'recap public key');

                    define('PRIVATE_KEY', 'recap private key');

 

                    # Did the user fail the captcha test?

                    $error = null;

require('./configs/reg_conf.php');

function doesUsernameExist($name){

    $exit = FALSE;

    $result = @mssql_query("SELECT * FROM ACCOUNT_TBL WHERE account='$name'");

    if (mssql_num_rows($result) != 0){

        $exit = TRUE;

    }

    return $exit;

}

 

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

    $user = preg_replace ("[^A-Za-z0-9]", "", $_POST['username']);

    $pass = preg_replace ("[^A-Za-z0-9]", "", $_POST['password']);

    if($_POST['username'] == ""){

        echo '<font color="red">Enter a user.</font><br /><br />';

    }

    else if($_POST['password'] == ""){

echo '<font color="red">Enter a password.</font><br /><br />';

    }

    else if ((strlen($_POST['username']) > 16) || (strlen($_POST['username']) < 3)){

echo '<font color="red">The user should be 3 to 16 characters.</font><br /><br />';

    }

    else if ((strlen($_POST['password']) > 16) || (strlen($_POST['password']) < 3)){

echo '<font color="red">The password should be 3 to 16 characters.</font><br /><br />';

    }

    else if($_POST['username'] != $user){

echo '<font color="red">User with invalid characters.</font><br /><br />';

    }

    else if($_POST['password'] != $pass){

echo '<font color="red">Password with invalid characters.</font><br /><br />';

    }

    else {

$pass = md5('kikugalanet' . $pass);

                if ($_POST["recaptcha_response_field"]) {

                        $response = recaptcha_check_answer(

                            PRIVATE_KEY, $_SERVER['REMOTE_ADDR'],

                            $_POST['recaptcha_challenge_field'],

                            $_POST['recaptcha_response_field']

                        );

 

                        if ( $response->is_valid ) {

                            # The user passed the reCAPTCHA test: form submission should continue

                            # Your other form validation logic should go here.

                       

                            # For example

                            # ... validate user input ...

                            # ... store form data in a database ...

                            # ... redirect to 'thank you' page

                       

                        }

                        else {

                            # The user failed the reCAPTCHA test so we need

                            # to fill in the error message and re-try the

                            # form submission

                            $error = $response->error;

                        }

                    }

            if(!doesUsernameExist($user)){

                $stmt = mssql_init('createaccount', $link);

                mssql_bind($stmt, '@account', $user, SQLVARCHAR, false, false, 15);

                mssql_bind($stmt, '@password', $pass, SQLVARCHAR, false, false, 32);

 

 

                mssql_execute($stmt) or die ("Something is wrong on the execution");

                mssql_free_statement($stmt);

echo '<font color="blue">Register Successful.</font><br /><br />';

            }

            else {

echo '<font color="red">User already Exist.</font><br /><br />';

            }

        }

mssql_close();

    }

 

echo '<form action="register.php" method="post">';

echo  recaptcha_get_html( PUBLIC_KEY, $error );

echo 'Username: <input type="text" name="username" /><br />';

echo 'Password: <input type="password" name="password" /><br />';

echo '<input type="submit" name="submit" value="Register" />';

echo '</form>';

 

?>

</body>

</html>

 

Also heres a test code for just recapture on its own which works:

 

    <html>

        <body>

            <form action="" method="post">

                <?php

                    # Get the reCAPTCHA library

                    require_once('recaptchalib.php');

 

                    # These are /not/ real keys - you must replace them with your *own* keys

                    # obtained from http://recaptcha.net/api/getkey

                    define('PUBLIC_KEY',  'public');

                    define('PRIVATE_KEY', 'private');

 

                    # Did the user fail the captcha test?

                    $error = null;

 

                    # This is where we process the user's response. We don't

                    # do this when the form is initially displayed - only

                    # when the user submits it.

                    if ($_POST["recaptcha_response_field"]) {

                        $response = recaptcha_check_answer(

                            PRIVATE_KEY, $_SERVER['REMOTE_ADDR'],

                            $_POST['recaptcha_challenge_field'],

                            $_POST['recaptcha_response_field']

                        );

 

                        if ( $response->is_valid ) {

                            # The user passed the reCAPTCHA test: form submission should continue

                            # Your other form validation logic should go here.

                       

                            # For example

                            # ... validate user input ...

                            # ... store form data in a database ...

                            # ... redirect to 'thank you' page

                       

                        }

                        else {

                            # The user failed the reCAPTCHA test so we need

                            # to fill in the error message and re-try the

                            # form submission

                            $error = $response->error;

                        }

                    }

               

                    # Display the reCAPTCHA challenge. The first time

                    # through $error will be null.

 

                    echo recaptcha_get_html( PUBLIC_KEY, $error );

                ?>

                <br />

                <!-- example form fields - your own fields go here -->

                Username: <input type="text" name="username" value="" /><br />

                Email address: <input type="text" name="email"    value="" /><br />

                <input type="submit" value="submit" />

            </form>

        </body>

    </html>

Here's mine... Hopefully you can take the bits you need:

 

<?php
include "recaptcha.php";

if (isset($_POST['submit'])) {
	$username = trim($_POST['username']); $password = trim($_POST['password1']); $password2 = trim($_POST['password2']); $email = trim($_POST['email']);
	$captcha = recaptcha_check_answer ($privatekey, $_SERVER['REMOTE_ADDR'], $_POST['recaptcha_challenge_field'], $_POST['recaptcha_response_field']);

	if ($password == NULL || $password2 == NULL || $email == NULL || $username == NULL)
		$error = "Please ensure that every field is complete.";
	else if (!$captcha->is_valid)
		$error = "The Captcha you entered was invalid. If you cannot read the text please click the refresh button. If you feel there's a problem with the Captcha system please <a href=\"mailto:[email protected]\">e-mail us</a> on: <a href=\"mailto:[email protected]\">[email protected]</a>";
	else if (!preg_match("/^[a-zA-Z0-9 ]+$/", $username))
		$error = "Your username can only contain numbers, letters and spaces.";
	else if (!preg_match("/^[a-zA-Z0-9 ]+$/", $password))
		$error = "Your password can only contain numbers, letters and spaces.";
	else if ($password != $password2)
		$error = "Your passwords did not match. Please ensure they're the same.";
	else if (strlen($username) > 25 || strlen($username) < 2)
		$error = "Your username must be between 2 and 25 characters in length.";
	else if (strlen($password) > 16 || strlen($password) < 4)
		$error = "Your password must be between 4 and 16 characters in length.";
	else if (strlen($email) > 70 || strlen($email) < 10)
		$error = "Your e-mail must be between 10 and 70 characters in length.";
	else if (!preg_match("/^\b[A-Z0-9._-]+@(?:[A-Z0-9-]+\.)+[A-Z]{2,4}$\b/i", $email))
		$error = "Your e-mail seems to be invalid.";
	else {
?>
