DaniWeb IT Discussion Community - Struggling with Captcha

Thank you very much for your reply.

I have given up on that particular script, and tried to install the captcha used by the author of my comment script (see here), which is the standard captcha v. 0.9.

I think my trouble is the integration because the captcha works seperately but I think the issue might be calling up php commands within the form that is in itself contained in a php file.

I am going to include and attach (1) test.php and (2)inc_rate.php (3) captcha.php.
I am trying to replicate the incorporation of captche in inc_rate.php

I have bolded and italiced my additions in the <form> part of inc_rate.php. Unfortunately, I get no more than a black bar as you can see on my .html page. :rolleyes:

This is the test.php where the captcha works in a simple form:

<html>

<head>

<title>captcha.php testing</title>

<style>

html {

border-left: 30pxsolid#222222;

}

input,textarea {

background: #333333;

color: #dddddd;

border: 2pxsolid#555555;

}

.captcha {

border: 2pxdashed: #331111;

background: #110000;

padding: 5px;

}

form {

border: 1pxdashed#551111;

padding: 2px;

}

</style>

</head>

<bodybgcolor="#000000"text="#ffffff">

<h1>CAPTCHA Test</h1>

<?php

define("CAPTCHA_INVERSE", 1);

include"captcha.php";

?>

 

<formaction="_test.1.php">

(we have an example input &lt;form&gt; here)<br>

<textareacols=50rows=3><?php

$res = captcha::check();

if (isset($res)) {

if ($res) {

$msg = "SUCCESS!!";

}

else {

$msg = "FAILED.";

}

for ($n=0; $n<5; $n++) {

echo"$msg\n";

}

}

?></textarea>

<br>

<br>

<?php

echocaptcha::form();

?>

<br>

<inputtype="submit"value="Test &amp; Save">

</form>

 

<br>

<br>

 

This is just an example. It's function-less form, which appears over

and over again. You'd typically also want to provide a more senseful

error message, if captcha::test() fails.

 

<br>

<br>

 

</body>

</html>

The following is my comment script php file - inc_rate.php:
