verifying use of form ("please enter code below")

Hi,

I have developed a form using HTML and PHP.

How easy is it to get a code verification box to stop spammers?

I want a box that above it says "please enter the code in the box below". The code would be random every time.

Hope you can help,

Matt.

 

User this captcha code http://www.google.com/recaptcha

 

Code for creating captcha box:
<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">
Add this code to your html form before submit code.
After this ,add below code to verify
<?php
if ($_SERVER['REQUEST_METHOD'] == 'POST')
{
if ($_POST['captcha'] == $_SESSION['cap_code'])
{
// Captcha verification is Correct. Do something here!
}
else
{
// Captcha verification is wrong. Take other action
}
}
?>..
Thanks...

 

Hi CreativeWebmaster.

I have used their code. And the ReCaptcha box appears. But it does not work with the form. How do I integrate it so that people cannot click send without entering the code?
