[SOLVED] Issues with Captcha

[Eggzorcist]

I have one major issue with my captcha, It's doing everything I want it to but one thing.

I thinks its alone on the page and makes my register.php a png image and outputting nothing else but itself.

 

heres my code:

<?php
function create_captcha($length){

//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;  

//image size
$width = 150;
$height = 50;

//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, 5, 15, 55, $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); 
}
?>

 

thanks

Instead of making it a function, just make it a standalone file. Then you need to call the filename as the image src.

 

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