Hallo Martin,
Ersatzweise zeig uns den relevanten Quellcode.
So long
Ja, es ist tatsächlich etwas long!
mailform.php: (ich weiß nicht, was davon alles wichtig ist - also lasse ich es komplett)

Ich habe jetzt extra nichts geändert, auch die Leerzeilen drin gelassen. Wie gesagt, es funktionierte perfekt. Es verwendet auch noch button.php:
<?php
session_start();
class createCaptcha {
function generateCode($characters) {
/* list all possible characters, similar looking characters and vowels have been removed */
$possible = '23456789bcdfghjkmnpqrstvwxyz';
$code = '';
$i = 0;
while ($i < $characters) {
$code .= substr($possible, mt_rand(0, strlen($possible)-1), 1);
$i++;
}
return $code;
}
function createCaptcha() {
$code = $this->generateCode(5);
$my_img = imagecreatefrompng('button.png');
$background = imagecolorallocate( $my_img, 0, 0, 255 );
$text_colour = imagecolorallocate( $my_img, 255, 255, 0 );
imagestring( $my_img, 4, 20, 3, $code, $text_colour );
header( "Content-type: image/png" );
imagepng($my_img);
imagecolordeallocate($text_color);
imagedestroy( $my_img );
$_SESSION['security_code'] = $code;
}
}
$captcha = new createCaptcha();
?>
Dazu gehört als letztes button.png (93 x 23 pixel, farbe: 444444)
Ich hoffe das hilft.
