CAPTCHA Not Working

[LaneLester]

All I'm seeing in the CAPTCHA is lines, no characters. This is in Firefox and IE.

Also, I am unable to disable the CAPTCHA function. I uncheck the box in Admin, save the change, but the box remains checked, and the CAPTCHA request is still displayed to the user.

Hi,

Can you post your phpinfo() page?

Also, I am unable to disable the CAPTCHA function. I uncheck the box in Admin, save the change, but the box remains checked, and the CAPTCHA request is still displayed to the user.

This is already fixed in CVS.

Thanks for testing!

bye

Hi,

'--with-ttf' '--with-freetype-dir=/usr' '--enable-gd-native-ttf'

you're mixing different TTF libraries in your PHP... I don't know if this breaks something... I think it's breaking something because you don't see any characters in the captcha.

Too bad, I'd like to use the system with captcha for the security. I have other sites with captcha on the same server; I guess they use a different approach (seen here).

Hi,

can you try this esample if this is working on your server?

http://de3.php.net/manual/en/function.imagettftext.php

When I upload the file to the server and then execute this:
http://www.newsandvie.ws/function.imagettftext.php
I get a page that lists a zillion php functions and then a section that starts with this:

imagettftext
(PHP 4, PHP 5)
imagettftext — Write text to the image using TrueType fonts
Description
array imagettftext ( resource $image, float $size, float $angle, int $x, int $y, int $color, string $fontfile, string $text )

Writes the given text into the image using TrueType fonts.

Hi,

can you create a test.php file with the following content and open the file inside your browser:

Code: Select all

<?php
// Set the content-type
header("Content-type: image/png");

// Create the image
$im = imagecreatetruecolor(400, 30);

// Create some colors
$white = imagecolorallocate($im, 255, 255, 255);
$grey = imagecolorallocate($im, 128, 128, 128);
$black = imagecolorallocate($im, 0, 0, 0);
imagefilledrectangle($im, 0, 0, 399, 29, $white);

// The text to draw
$text = 'Testing...';
// Replace path by your own font path
$font = 'arial.ttf';

// Add some shadow to the text
imagettftext($im, 20, 0, 11, 21, $grey, $font, $text);

// Add the text
imagettftext($im, 20, 0, 10, 20, $black, $font, $text);

// Using imagepng() results in clearer text compared with imagejpeg()
imagepng($im);
imagedestroy($im);
?>

This is what I get:

Firefox:

Hi,

the arial.ttf file have to be in the same folder as the PHP file...

They are.

And I just figured out the problem: I had gFTP set to upload in ASCII instead of binary. After arial.ttf was uploaded in binary, the test file worked perfectly.

Hi,

can you check that for the three .ttf files in the phpMyFAQ font/ folder, too?

That was it!

My usual practice is to upload everything except the images folder as ASCII. I guess I need to watch out for those TTF's!
