Geeklog Forums

I'm trying to impliment GL Captcha 1.0 and can't seem to the something right. Maybe I'm just dense.

Anyway when I try to modify my lib-custom get errors. something about variable being already declared. Can someone drop me a pre hacked lib-custom or tell me where to make the modifications.

Thanks,
Ron

Ron,

If you can give me a specific error message, I bet we can get you fixed up. Sorry, but I don't work so well with 'something about variable being already declared', that could be all kinds of problems and I wouldn't know where to start. But, the actual error message will help narrow it down.

Thanks!

I added the lines to lib-custom and I get this. Also the memberdetail example doesn't find the images. I am using gd lib.

Okay I seem to have everything installed and working except that the image doesn't display. When I look at properties it says

www.mysite.com/captcha/captcha.php?.png

I'm trying to figure out what it's not displaying properly but if you have an idea let me know. Maybe I have something in the wrong location.

Ron,

There are a couple of configurations you can try to see if you can get things to work. First, try the different graphic drivers. In public_html/captcha.php change the $gfxDriver to 0 for GD libs, if that doesn't work, then try 1 for ImageMagick and if that fails, give the static image method a try by setting it to 2.

What I've seen happen is that a lot of GD and ImageMagick graphic package installs do not seem to support True Type Fonts which are used to actually create the image. This is why I have the static image option, it doesn't rely on any external graphic packages.

Let me know if this helps.

Thanks!
Mark

I've tried all 3 and get the same results for all three.

Ron,

Where do you have the static images stored?

The program is looking for them in the:

$_CONF['path'] . '/captcha-images/ directory. Where $_CONF['path'] is defined in your Geeklog config.php file.

Are they there? And are the permissions set properly on that directory so the web server can read files there?

Thanks!
Mark

F:\geeklog\captcha-images

OK, in your Geeklog config.php, what is $_CONF['path'] set to? If it isn't F:\Geeklog then we'll need to move the captcha-images so the /captcha-images/ directory is under whatever directory is show in $_CONF['path'].

But, if it is in the right place, are you sure the web server can read that directory. It looks like you are running on a Windows box, are you using Apache or IIS as the web server? If it is IIS, you'll probably need to specifically add the proper permissions to that directory so the web server can open and read the graphic images stored there.

Thanks!
Mark

$_CONF['path'] = 'F:/geeklog/';


Neither, I am on Win XP running Xitami web server. However what you said may give me an idea. Of course the web server can find and read the geeklog files. I am running gd lib and ImageMagick and have tested ImageMagick and it seems to work ok.

Where can I change the path information if I were to put the captcha-images elsewhere?

Ron

The path is hardcoded in captcha.class.php. You can edit it and change line 179, it will look like this:


Just change the $_CONF['path'] . '/captcha-images/' to wherever you put the images.

Thanks!
Mark

I tried running http://www.miplanet.com/captcha/captcha.php?.png by itself and it returns text no matter which I try 0, 1 or 2. With 2 (static) I also get the css text. Go ahead and take a look.

Ron

Ron,

I think the issue may be with how the image is being sent. I went to the URL you gave me and sure enough it doesn't work, but if I view the source of the page, I can actually see all the binary data for the image.

The way I send the image is this:

I send a header stating the image type and then send the image data. My guess is that the Xitami web server does not like this method. I'm not sure how to correct this, sending image data this way is pretty standard stuff. Anything in the server docs that might give me a hint on how I can do it differently for that server?

Thanks!
Mark

It very well could be the header. All Xitami documentation is on it's website www.xitami.com.

here are the Xitami mime types I can add whatever we need.

Okay, I have made a little progress. It appears that the Geeklog header is over riding the header sent by the captcha script. Now I need to figure out why. What I did was create a small php file like so just to test. If I include the require_once line it doesn't work if I remark it out like below it works.

Ron,

I'm not sure the CAPTCHA will work properly without lib-common.php being included. It sounds like your web server doesn't like having a content header sent mid-stream. I've done extensive testing with Apache and IIS and haven't seen any issues like this with them. Maybe you could use the server's support forums and see if anyone else has had an issue like this or has a work around?

Thanks!
Mark

I got the same problem.

If some one will find this topic hope this solusion will help him.

You need to remove any symbols aftrer "?>" "cr" "lf" and others characters in all included files by lib-common.php (plugin's functions.inc and so).
Server understand it as HTML code and send it to client with own headers.
Then capthca whant to send its own headers but it cause errors because headers was sent already.

Are you actually using Captcha 1.0? The latest version is 3.0.2 assuming you are running GL 1.4.1.

Actually our project based on GL 1.3.11 and can't be upgraded for now because of many changes implemened in GL core.

Thanks, I will look at new version when I have a time.
