Help, Why my spam code wont display?

[kyme]

Hello,

Im newbie in PHP, and till now stil learning php..

I'm sorry but im really a pretty slow in comes of programming.

But im trying my best not to discourage and keep it up till i get my goal.

I really2x want to learn php & be part of it and starting to love on it, cause

i know i can do it with PHP.

Now im working a project a which has a spam code before it would submit and

email it. But my problem is, It would not display the spam code or captcha..

Heres my code.

 

Html form

<form action="page/contact.php" method="post" style="size:inherit" align="center">

<p>Name: </br><input type="text" size="20" name="name" onFocus="doFocus(this,'name'); return false;"/></p>

 

<p>Email:</br><input type="text" size="20" name="email"/></p> <p>Message </p>

<textarea width="15" height="40" name="message" style="overflow-x:hidden;"

rows="5" cols="20" onFocus="doFocus(this,'message'); return false;" />

</textarea>

<br /><br/>

Enter code below:

<img src="page/secimg.php"> <br/>

<input type="text" name="Spam Code" size="7" /> <br/>

<input type="submit" name="submit" value="SEND"size="5" name="email"/>

 

</form>

 

And heres my PHP script

<?php

session_start();

 

$width = 120;

$height = 40;

$font = 'monofont.ttf';

 

$length=5;

$possible = '1234567890bcdfghjkmnprstvwxyzABCDEFJKMNPTUVWXY';

$i = 0;

while ($i < $length) {

$string .= substr($possible, mt_rand(0, strlen($possible)-1), 1);

$i++;

}

 

 

 

//$captcha = imagecreatefrompng("./captcha.png");

$captcha = imagecreate($width, $height);

 

 

$back = imagecolorallocate($captcha, 0, 0, 55);

$fore = imagecolorallocate($captcha,233,239,239);

//$fore = imagecolorallocate($captcha,255,255,255);

 

//imageline($captcha,40,0,64,29,$line);

$n_lines = mt_rand(6, ; // random number of lines

for ($i = 0; $i < $n_lines; $i++) {

$tm = mt_rand(1, 2); // random types of lines

if ($tm == 1) {

$x1 = 0;

$y1 = mt_rand(0, $height);

$x2 = $width;

if ($y1 > $height / 2)

$y2 = mt_rand(0, $height * 0.3);

else

$y2 = mt_rand($height * 0.5, $height);

}

elseif ($tm == 2) {

$x1 = mt_rand(0,$width);

$y1 = 0;

if ($x1 > $width / 2)

$x2 = mt_rand(0, $width * 0.3);

else

$x2 = mt_rand($width / 2,$width);

$y2 = $height;

}

imageline($captcha,$x1,$y1,$x2,$y2,$fore);

}

 

$angle = mt_rand(-14,14); // add some angle

$fontsize = $height * 0.70;

$bounds = imagettfbbox($fontsize, $angle, $font, $string);

//var_dump($bounds);

list(,$btmleftY,,$btmrightY,$toprightX,$toprightY,,) = $bounds;

//$x = ($width - $toprightX)/2;

$y = ($height - $toprightY)/2;

$x = mt_rand(5, $width - $toprightX - 5);

 

$shootL = $height - $btmleftY;

$shootR = $height - $btmrightY;

if ($shootL > 0) $y - $shoot;

else if ($shootR > 0) $y - $shoot;

 

imagettftext($captcha, $fontsize, $angle, $x, $y, $fore, $font , $string);

 

 

$_SESSION['key'] = md5($string);

 

/*

Output the image

*/

header("Content-type: image/png");

imagepng($captcha);

imagedestroy($captcha);

?>

 

In this part were it all checks the each textbox to verify

<?php

define("kContactEmail","name@email.com");

 

// init variables

$error_msg = "The following fields were left empty or contain invalid information:<ul class='error'>";

$error = false;

 

 

function checkEmpty($names, $data) {

$n = count($names);

$emptys = array();

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

if (empty($data[$names[$i]])) $emptys[] = $names[$i];

}

return $emptys;

}

 

 

function createUList($arr) {

$n = count($arr);

echo '<ul>';

for ($i = 0; $i < $n; $i++)

echo " <li>".str_replace('_',' ',$arr[$i])."</li>\n";

echo '</ul>';

}

 

 

// determine is the form was submitted

$submit = $_POST['submit'];

if (empty($submit))

$form_submitted = false;

else

$form_submitted = true;

 

if ($form_submitted) {

 

$emptyFlds = checkEmpty($infoToCheck,$_POST);

 

if($emptyFlds){

}

else{

 

// read out data

$name = $_POST['name'];

$email = $_POST['email'];

// $subject = $_POST['subject'];

$message = $_POST['message'];

 

 

$validSecurityCode = md5($_POST['Spam_Code']) == $_SESSION['key'];

 

 

// verify required data

 

if ($noEmptyFlds && $validSecurityCode)

{

unset($_SESSION['key']); // prevent multiple send

$headers .= "MIME-Version: 1.0\r\n";

$headers .= "Content-type: text/html; charset=iso-8859-1\r\n";

}

if(!$name) { $error_msg .= "<li>Full Name</li>"; $error = true; }

if(!$email) { $error_msg .= "<li>E-mail Address</li>"; $error = true; }

// if(!$subject) { $error_msg .= "<li>Subject</li>"; $error = true; }

if(!$message) { $error_msg .= "<li>Message</li>"; $error = true; }

if($email) { if(!eregi("^[a-z0-9_]+@[a-z0-9\-]+\.[a-z0-9\-\.]+$", $email)){ $error_msg .= "<li>E-mail Address</li>"; $error = true; }}

$error_msg .= "</ul>";

 

// email message if no errors occurred

if (!$error) {

// prepare message

$msg = "Full Name: \t $name \n";

$msg .= "E-mail Address: \t $email \n";

$msg .= "Message: \n---\n $message \n---\n";

 

// prepare message header

$mailheaders = "MIME-Version: 1.0\r\n";

$mailheaders .= "Content-type: text/plain; charset=iso-8859-1\r\n";

$mailheaders .= "From: $name <$email>\r\n";

$mailheaders .= "Reply-To: $name <$email>\r\n";

 

// send out email

mail(kContactEmail, $subject ,stripslashes($msg), $mailheaders);

}

}

}

?>

  Hello sir,

            I tried to read it and i dont understand a little bit. What does GD do?

  And how to work out?

 

  My friend just tested this up before i have implemented on it. And it works fine and

  100% working. Now i have tried the codes but in my page doesnt work and never it

  displayed

 

  Could anyone help me that more understandable and i can easly catch up.

  Thanks..

GD takes care of image processing, so any images, like captchas require this image processing so they can be displayed. PHP uses the library to create the images...try uploading a php file, and using phpinfo(); function.... gd should be listed....and it will tell you if its on or off...

Now it works, it displays now an spam code but the problem now is the

How it test if it is correct...

 

Heres the code , In this part it wont test if the spam box was correct filling on it.

<?php

define("kContactEmail","name@email.com");

 

// init variables

  $error_msg = "The following fields were left empty or contain invalid information:<ul class='error'>";

  $error = false;

 

 

  function checkEmpty($names, $data) {

  $n = count($names);

  $emptys = array();

  for ($i = 0; $i < $n; $i++) {

if (empty($data[$names[$i]])) $emptys[] = $names[$i];

  }

  return $emptys;

}

 

 

  function createUList($arr) {

$n = count($arr);

echo '<ul>';

for ($i = 0; $i < $n; $i++)

echo " <li>".str_replace('_',' ',$arr[$i])."</li>\n";

echo '</ul>';

}

 

 

  // determine is the form was submitted

  $submit = $_POST['submit'];

  if (empty($submit))

$form_submitted = false;

  else

$emptyFlds = checkEmpty($infoToCheck,$_POST);

 

if($emptyFlds){

}

else{

 

  // read out data

  $name = $_POST['name'];

$email = $_POST['email'];

  //   $subject = $_POST['subject'];

$message = $_POST['message'];

 

 

$validSecurityCode = md5($_POST['Spam_Code']) == $_SESSION['key'];

      $error_msg .= "</ul>";

 

I think i have problem in this part, i have something miss it? Still no solution..

[kyme]

Actually it wont test once i fill w/ the spam code..

[stelthius]

you will know if captcha is working as it will tell you wrong security code, if you know the code is correct id suggest looking at the rest of your script i have a catpcha script i wrote up and use it on a register form, email us form, and a bulletin blog ill show you a example let me dig out my code and ill post it up it may or may not help you.
