[SOLVED] Captcha Help

[jaikob]

I have this code:

 

<img src="<?php 
$captcha = imagecreatefrompng("captcha.png");
$black = imagecolorallocate($captcha, 0, 0, 0);
$line = imagecolorallocate($captcha,233,239,239);
imageline($captcha,0,0,39,29,$line);
imageline($captcha,40,0,64,29,$line);
imagestring($captcha, 5, 20, 10, $string, $black);
header("Content-type: image/png");
imagepng($captcha); ?>" />

 

 

but all i get is a bunch of giberish like this: �8�OLW�C�A���C� �x���&���&fs6U��%R�I� V�P0Q�Y��i�t�S#��a�n%�&x�(���kv���ۘ� 7

 

how do i fix this.

 

ps, I cannot include this on an include or seperate php file, it has to be in the same file, so i can work with vars set in a previous code on the page.

You have to link to it. Thats the way it works. If you need to use other variables, either pass them in the URL, or set a session. You should have one php file, lets say captcha.php with your image generation code, and then you should use:

 

<img src="captcha.php?foo=bar" />
