Hallo,
ich habe mir ein Kontaktformular mit Captcha aus dem Internet runtergeladen, hat alles geklappt.
Nun würde ich gerne einen anderen Teil meiner Seite auch mit einem Captcha-Code versehen, das ganze soll ungefähr so aussehen:
Link: [Textfeld]
Captchabild: [Textfeld]
Submit
Hier ist der Code den ich für das Kontaktformular benutze:
HTML Code:
<?php
$your_email ='
';
session_start();
$errors = '';
$name = '';
$visitor_email = '';
$visitor_skype = '';
$user_message = '';
if(isset($_POST['submit']))
{
$name = $_POST['name'];
$visitor_email = $_POST['email'];
$visitor_skype = $_POST['skype'];
$user_message = $_POST['message'];
///------------Do Validations-------------
if(empty($name)|| empty($visitor_email))
{
$errors .= "\n Name and Email are required fields. ";
}
if(IsInjected($visitor_email))
{
$errors .= "\n Bad email value!";
}
if(empty($_SESSION['6_letters_code'] ) ||
strcasecmp($_SESSION['6_letters_code'], $_POST['6_letters_code']) != 0)
{
//Note: the captcha code is compared case insensitively.
//if you want case sensitive match, update the check above to
// strcmp()
$errors .= "\n The captcha code does not match!";
}
if(empty($errors))
{
//send the email
$to = $your_email;
$subject="Contact (US)";
$from = $your_email;
$ip = isset($_SERVER['REMOTE_ADDR']) ? $_SERVER['REMOTE_ADDR'] : '';
$body = "Name: $name\n".
"Email: $visitor_email \n".
"Skype: $visitor_skype \n".
"Message: \n ".
"$user_message\n".
"IP: $ip\n";
$headers = "From: $from \r\n";
$headers .= "Reply-To: $visitor_email \r\n";
mail($to, $subject, $body,$headers);
header('Location: refresh.html');
}
}
// Function to validate against any email injection attempts
function IsInjected($str)
{
$injections = array('(\n+)',
'(\r+)',
'(\t+)',
'(%0A+)',
'(%0D+)',
'(%08+)',
'(%09+)'
);
$inject = join('|', $injections);
$inject = "/$inject/i";
if(preg_match($inject,$str))
{
return true;
}
else
{
return false;
}
}
?>
