Hi, it's my first time using captcha with PHP, I think I'm pretty close. I can get it echo everything is right or whatever when the fields are filled in correctly and correct words are entered, but what I can't do is make it run the script from another file when everything does work as I can't use PHP header as html is already there and I tired javascript but the variables weren't passed. Any help will be very appreciated, here is the code:
<?php
$link = mysql_connect('', '', '');
if (!$link) {
die('Could not connect: ' . mysql_error());
}
echo 'Connected successfully';
mysql_select_db();
if (eregi('^[[:alnum:]\.\'\-]{4,30}$', stripslashes(trim($_POST['username']))) ) {
$username = mysql_real_escape_string($_POST['username']);
$query = "SELECT username FROM users WHERE username = '$username'";
$result = @mysql_query($query);
$num = @mysql_num_rows($result);
if ($num> 0) {
$errors[] = '<font color="red">The username you have chosen has already been taken, please try again.</font>';
} else {
$username = mysql_real_escape_string($_POST['username']);
}
} else {
$errors[] = '<font color="red">Please provide a valid username between 4 and 30 characters.</font>';
}
if (!eregi('^[a-zA-Z]+[a-zA-Z0-9_-]*@([a-zA-Z0-9]+){1}(\.[a-zA-Z0-9]+){1,2}', stripslashes(trim($_POST['email'])) )) {
$errors[] = '<font color="red">Please provide a valid email address.</font>';
} else {
$email = mysql_real_escape_string($_POST['email']);
}
if (!empty($_POST['password1'])) {
if ($_POST['password1'] != $_POST['password2']) {
$errors[] = '<font color="red">The 2 passwords you have entered do not match.</font>';
} else {
$password = $_POST['password1'];
}
} else {
$errors[] = '<font color="red">Please provide a password.</font>';
}
//Recaptcha script
// call the lib..
require_once('recaptchalib.php');
// Get a key from http://recaptcha.net/api/getkey
$publickey = "xxxxxxxxxxxxxxxxxxxxxxxxxx";
$privatekey = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
# was there a reCAPTCHA response?
if ($_POST["submit"]) {
$response = recaptcha_check_answer($privatekey,
$_SERVER["REMOTE_ADDR"],
$_POST["recaptcha_challenge_field"],
$_POST["recaptcha_response_field"]);
if (empty($errors) && ($response->is_valid)) {
*** //Here is where I would to insert the header or whatever to registerscript.php
***
} elseif (!empty($errors)) {
echo '<h3>Error!</h3>
The following error(s) occured:<br />';
foreach ($errors as $msg) {
echo " - <font color=\"red\">$msg</font><br />\n";
}
}
else {echo 'Sorry, those words did not match the image';}
}
?>
<html>
<h3>Register</h3>
<form method="post">
<p><input type="text" name="username" value="<?php if (isset($_POST['username'])) echo $_POST['username']; ?>" size="30" maxlength="30" /> <small>Username</small></p>
<p><input type="password" name="password1" size="30" maxlength="40" /> <small>Password</small></p>
<p><input type="password" name="password2" size="30" maxlength="40" /> <small>Confirm Password</small></p>
<p><input type="text" name="email" size="30" maxlength="30" value="<?php if(isset($_POST['email'])) echo $_POST['email']; ?>" /> <small>Email Address</small></p>
<?php echo recaptcha_get_html($publickey, $error); ?>
<input style="width: 317px" type="submit" value="submit" name="submit"/>
</form>
<p>If you are already registered, <a href="http://...login.php">log in</a></p>
</html>
It all works properly, the erros messages etc., so just the redirect bit.
I also realise I haven't encrypted password and probably have escaped MySql but will do that before it goes live.
Thanks for your help
