Question about captcha in DX Auth library

[eluser]Toad[/eluser]
Hi,

I'm using the DX Auth library to authenticate users. It works fine. I just noticed that a new image is created in the captcha folder every time a captcha is need in the application. The problem is that those images are not removed when not needed anymore...

After a few weeks of tests, I have more than a hundred captcha images in the folder. Is there a way to automatically delete them?

Thanks a lot =)

Sure, just setup a cron job and use a variation of the find command to delete images older than x number of days

[eluser]Toad[/eluser]
I already thought about cron. I just expected another solution, included in the library...

Anyway, your solution seems to be the best one...

Thanks =)

You could use this recaptcha example and then you wouldn't have to deal with cleaning up images at all.

I will stay on the DX_Auth captcha and cron job. I have already seen recaptcha on the internet but I don't like the communication between my server and their server, for security reasons (yeah sometimes I'm a bit paranoiac...)

Thanks for your help =)

Hi all,
I'm in trouble with captcha, I have installed dx_auth with captcha enabled and recaptcha disabled.
Session in db is disabled too (just for more informations).
the problem is everytime I use captcha (registration,login,ecc) the $this->dx_auth->get_auth_error() method return this error: "Your confirmation code has expired. Please try again."
The captcha is visible and the file .png was created in the right folder, please can you help me?
Thanks in advance

Ok, I solve it....

The flash_data was removed every request and the captcha infos with these.
The flash_data was removed because session expires every request.
The session expires because the cookie domain in config file was wrong.

Bye

I solved this By using Normal session data instead Flashdata, in Tank_Auth.
