[SOLVED] CAPTCHA Session NULL

Recommended Posts

I'm not sure why my capcha session is null when I try to echo it nothing shows up.

 

<?php

$length = 5;
$width = 150;
$height = 50;

//Creates md5 hash
$hash = md5(rand(0, 9999));

//creates a code with $length  
$code = substr($hash, 15, $length);

//stores the code into a session
$_SESSION['captcha'] = $code;


//creates the image
$image = imagecreate($width, $height); 

//creates background and text colours
$background = imagecolorallocate($image, 0, 0, 0);
$text = imagecolorallocate($image, 255, 255, 255);

//creates the image
imagefill($image, 0, 0, $background); 

//Specifies font and text
imagettftext($image, 42, 8, 12, 60, $text, "captcha.ttf", $code);

//Tells the browser what kind of image is being outputted. 
header("Content-Type: image/png"); 

//creates the image
imagepng($image);

//frees up resources
imagedestroy($image); 

?>

 

this is how i included it.

<img src="captcha/captcha.php" alt="captcha" />
