[SOLVED] Vericode Problems

Hi,

I’m trying to add vericode to my eForm that uses version 1.4.4. but it isn’t displaying an image. I am getting a "not available image" which points to http://site.com/manager/includes/veriword.php?rand=2003364844 This problem is not really eForm specific, but hopefully in the correct place anyways.

Now if I target that address directly I get an fatal error which is probably the cause of the problem:
Fatal error: Call to undefined function imagettfbbox() in /site/manager/includes/veriword.php on line 126

Line 126 looks like:
$box = imagettfbbox ( $text_size, $text_angle, $text_font, $this->word);

Initially I thought that GD image wasn’t installed but according to phpinfo.php (and the provider) it is, using version "bundled (2.0.28 compatible)".

I’m using a 0.9.6 MODx & PHP 5.1.2 and would be grateful for any solution anyone can offer!
[EDIT]
After some more hunting it would appear that FreeType Support hasn’t been enabled. For anyone else as clueless as me when it comes to this sort of thing you can create a snippet with

<?php
var_dump(gd_info());
?>

which will return an array showing what exactly has been turned on and what not.

Here is the output regarding GD etc:

array(12) { ["GD Version"]=> string(13) "2.0 or higher" ["FreeType Support"]=> bool(true) ["FreeType Linkage"]=> string(13) "with freetype" ["T1Lib Support"]=> bool(true) ["GIF Read Support"]=> bool(true) ["GIF Create Support"]=> bool(true) ["JPG Support"]=> bool(true) ["PNG Support"]=> bool(true) ["WBMP Support"]=> bool(true) ["XPM Support"]=> bool(false) ["XBM Support"]=> bool(false) ["JIS-mapped Japanese Font Support"]=> bool(false) }

So, it looks like its on and ready, but images are still not showing up for me. Any ideas ?

Without more info about your form and eform calls no, no idea. I’m guessing you’re missing the

 <img src="[+verimageurl+]" />

in your template?

The form part is ok it seems. So what happens if you type in the /manager/includes/veriword.php?rand=1850393639 address directly into your browser?

I spent a lot of time futzing with the veriword function while working on the SPForm snippet. It’s very cranky and hard to troubleshoot. If you put any code in the veriword file to help you debug (echo or print statements) it won’t work because the image has to be the only output.

If the GD functions are on, the most likely culprit is the path to the veriword file, especially if you get output using TobyL’s suggestion. Another test is to turn on CAPTCHA for the manager login and see if you get an image that way (although, if you don’t, you may have to turn it back off in the database using PhpMyAdmin in order to log in).

I ended up moving the veriword file to the snippet directory and using something like this:

$verifyUrl=$modx->config[’site_url’].$spformPath.’spfveriword.php’;

Remember, too, that you have to clear the site cache and your browser cache each time you make a change or you may not see the results of your change.

1. There is no output if I visit that image url directly. Just an empty page (no source code either).

2. If I enable captcha in the site’s general configuration settings, it does not appear on the manager login page, which makes me suspect GD related issues.

3. None of the modx code has been modified, including any debugging stuff.

4. This issue occurs on multiple installs of modx.

Here is my GD as displayed on phpinfo:

GD Support 	enabled
GD Version 	2.0 or higher
FreeType Support 	enabled
FreeType Linkage 	with freetype
FreeType Version 	2.2.1
T1Lib Support 	enabled
GIF Read Support 	enabled
GIF Create Support 	enabled
JPG Support 	enabled
PNG Support 	enabled
WBMP Support 	enabled

It sure sounds like a problem with the hosting service’s GD setup.
