Besides the BAD BEHAVIOR and the hack to aprove entry's in the Admin there still aint a hack for the generated numbers.
I believe that's the only way so the guestbook stays a guestbook. If i post a comment in a guestbook and have to wait 2 days before it shows up I realy don't call that a guestbook.
anyone the knowhow for the generated numbers before my visitors may post?
Let's make a start:
Code: Select all
<?php /*
example of usage:
inside your form
<input type="text" name="validator" id="validator" size="4" />
<img src="random.php" alt="CAPTCHA image" width="60" height="20" vspace="1" align="top" />
and test the value of the "validator" form field like:
if (!empty($_POST['validator']) && $_POST['validator'] == $_SESSION['rand_code']) {
process your form here
at least destroy the session
unset($_SESSION['rand_code']);
*/
// save this code in your random script
session_start();
if (empty($_SESSION['rand_code'])) {
$str = "";
$length = 0;
for ($i = 0; $i < 4; $i++) {
// this numbers refer to numbers of the ascii table (small-caps)
$str .= chr(rand(97, 122));
}
$_SESSION['rand_code'] = $str;
}
$imgX = 60;
$imgY = 20;
$image = imagecreatetruecolor(60, 20);
$backgr_col = imagecolorallocate($image, 238,239,239);
$border_col = imagecolorallocate($image, 208,208,208);
$text_col = imagecolorallocate($image, 46,60,31);
imagefilledrectangle($image, 0, 0, 60, 20, $backgr_col);
imagerectangle($image, 0, 0, 59, 19, $border_col);
$font = "VeraSe.ttf"; // it's a Bitstream font check www.gnome.org for more
$font_size = 10;
$angle = 0;
$box = imagettfbbox($font_size, $angle, $font, $_SESSION['rand_code']);
$x = (int)($imgX - $box[4]) / 2;
$y = (int)($imgY - $box[5]) / 2;
imagettftext($image, $font_size, $angle, $x, $y, $text_col, $font, $_SESSION['rand_code']);
header("Content-type: image/png");
imagepng($image);
imagedestroy ($image);
?>
Does anyone know which file builds the form? and maybe a litle hint to the right setup....
