Request Form with PHP Captcha script not working

Wolverine68 · May 13, 2010

I created a request form with a CAPTCHA script (for filtering out spammers). If the form is submitted without the correct string it is suppose to give an error message. If the form is submitted with the correct string then it's suppose to give a thank you message along with the current time and date.

I've tested both scenarios but in both cases it just goes to a blank screen. Here's the link to the form:

HTML form code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<?php
session_start();

The captcha doesn't appear to actually do anything, but first things first. Change your feedback11.php to the following, and see what happens.

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 strict//EN" "[url=http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd]http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd[/url]">
<html>
<body>
<?php
$checkbox0 = $_POST['Programs'][0];
$checkbox1 = $_POST['Programs'][1];
$checkbox2 = $_POST['Programs'][2];
$checkbox3 = $_POST['Programs'][3];
$checkbox4 = $_POST['Programs'][4];
$checkbox5 = $_POST['Programs'][5];
$formBody="Name:$name\nEmail:$email\nPhone:$phone\nAddress:$address\nI'd like more information on the following programs: $checkbox0, $checkbox1, $checkbox2, $checkbox3, $checkbox4, $checkbox5 \nComments:$comments";
$headers = "From:$email";

if ($submit) {
   mail("[email][email protected][/email]", "Church Information Request",$formBody, $headers);
   print "Thank you. Your request has been submitted <br /> <br />";
   print "Current date and time :";
   print date("F j, Y  g:i A T");
} else {
   echo "Submit is NOT set.";
}
?>
