the code u gave is a very useful but simple. u can use a html contact from with capctha,
following is the code if u want to use

The contact form with CAPTCHA

Here is the HTML code for the contact form:

<form method="POST" name="contact_form"
action="<?php echo htmlentities($_SERVER['PHP_SELF']); ?>">
<label for="name">Name: </label>
<input type="text" name="name"
value="<?php echo htmlentities($name) ?>">
<label for="email">Email: </label>
<input type="text" name="email"
value="<?php echo htmlentities($visitor_email) ?>">
<label for="message">Message:</label>
<textarea name="message" rows=8 cols=30
><?php echo htmlentities($user_message) ?></textarea>
<img src="captcha_code_file.php?rand=<?php echo rand(); ?>"
id="captchaimg" >
<label for="message">Enter the code above here :</label>
<input id="6_letters_code" name="6_letters_code" type="text">
<input type="submit" value="Submit" name="submit">
</form>
The HTML form above contains the fields for name, email and message. In addition, we have the CAPTCHA image. The <img> tag for the CAPTCHA image points to the script captcha_code_file.php. The PHP script in 'captcha_code_file.php' creates the image for the captcha and saves the code in a session variable named '6_letters_code'.

Validating the CAPTCHA

When the form is submitted, we compare the value in the session variable(6_letters_code) with the submitted CAPTCHA code( the value in the text field 6_letters_code). If the codes match, then we proceed with emailing the form submission. Else we display an error.

Here is the code that does the server side processing:

if(isset($_POST['submit']))
{
if(empty($_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="New form submission";
$from = $your_email;
$ip = isset($_SERVER['REMOTE_ADDR']) ? $_SERVER['REMOTE_ADDR'] : '';
$body = "A user $name submitted the contact form:\n".
"Name: $name\n".
"Email: $visitor_email \n".
"Message: \n ".
"$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: thank-you.html');
}
}
Customizing the CAPTCHA

The CAPTCHA script in the sample code download can be customized. If you open the script, you can see the first few lines of the code as shown below:

$image_width = 120;
$image_height = 40;
$characters_on_image = 6;
$font = './monofont.ttf';
//The characters that can be used in the CAPTCHA code.
//avoid confusing characters (l 1 and i for example)
$possible_letters = '23456789bcdfghjkmnpqrstvwxyz';
$random_dots = 0;
$random_lines = 20;
$captcha_text_color="0x142864";
$captcha_noise_color = "0x142864";
You can change the size of the CAPTCHA by changing $image_width & $image_height. The number of characters in the CAPTCHA can be changed by updating $characters_on_image. Similarly, the text color of the CAPTCHA can be customized by updating $captcha_text_color. The code adds some 'noise' in the image by adding random lines and dots. you can increase or decrease the noise. Please note that increasing the noise may make it difficult for your genuine visitors to read the code.

Hi, I'm new with php.
I tried copy&paste the html and php files ,which was posted by RibbitHost on 7/3/2011, on to my website and uploaded both, but it didn't work for me. When I input contact form and click send, I get error and connect to 000webhost site.
In order for form to work, i need to upload the html form file and the php files, right?

I've been trying to figure out php form for days. Can any body help me?

I don't quite understand what you mean, tomyam.

I wound up going to mycontactform.com. Their version worked.
