For next version of ShoutBox module I thought I would revisit the use of captcha images for anonymous posts. By rights the image id tag of the captcha image should be unique so there are no conflicts if another instance appears on the same page. For example, the person who reported this had defined the shoutbox block to appear in the Right column on All Pages. Therefore it would appear on the Registration page which also employs captcha. So now we have two instances of captcha but both images have the same id tag, which is the default one provided in the class config file.

I am working with 2.3.3 as I explore this issue. I thought it should be as simple as calling setConfig() but it appears not. Here is what my code looks like in the block.



Calling setConfig appears to have no affect on the config value. Am I overlooking something?

Is the name not to be added as second argument in the new XoopsFormCaptcha?

You are correct ghia. That is actually where I started. As I worked through how the class is supposed to work I eventually narrowed it down to the setConfig method that appears to be the problem.

The image.php file contains the code which renders the image and makes the tag assignment. Here is the specific code I am looking at:



From what I have been able to figure out I believe that once the "name" value is assigned in the config array contained in the config.php it can not be changed. This is based on the following found in xoopscaptcha.php:



As soon as the config array is loaded $this->name is also assigned so performing the setConfig can reassign $this->name but not $this->config["name"].

Even though I figured out a hack to make the image id's unique the first image is still overwritten by the second image.
