Support/Comments for Captcha 3.2.4-beta1

This is an auto-generated topic for Captcha 3.2.4-beta1 by bobray.

Brief Description:

This utility provides captcha verification in the MODxManager login.It uses 5 system settings:
captcha.enabled - If set, the captcha function is turned on
captcha.use_mathstring - If set, the image is a simple equation for the user to solve
captcha.words - Selection of words used for the image if captcha.use_mathstring is off
captcha.height - Height of captcha image in pixels
captcha.width - Width of captcha image in pixels

The Captcha components can also be used by other components to create captcha-style verification for front-end forms.

great, thanks bob.
i’m sure i’ll check it later.

The only real changes in the last few versions are bugfixes related to installation. It now checks for the necessary graphics functions before installing and I fixed a problem with case-sensitivity on the package name for some servers.

Would love to see this integrated into other extras like quip or forms.

I think FormIt and Quip do reCapthca and FormIt has its own mathstring. I think you could use Captcha in FormIt with a placeholder for the image, a preHook to render the Captcha image and set the placeholder, and a custom validator to check the $_SESSION variable.

I don’t like recaptcha as I find it awkward occasionally, especially for smaller website where highest level of spam protection is really not necessary.

Same here. In theory, it shouldn’t be too hard to copy, rename, and modify the recaptcha code to create a captcha hook.

Well, that’s still few steps ahead of my modx knowledge - I’m still learning. In mean time I will keep close look to this part of the forum until I come up with something.

Hello All,

I am very annoayed because I installed MODx Revo, yesterday and I actived captcha.

Now, when I go to manager, I have a captcha calcul and when I press "Login" it ternun an error message "$_SESSION Variable not set"

Also I went to my database, to the table "modx_system_setting" -> captcha.enabled and cnaged the value to 0.

I still have the calcul to do and the error message.

Any idea to let me login and solved a such error message

After changing the DB, you need to manually delete the files in the core/cache directory before trying to log in.

It looks like your install has trouble saving Session variables, which are required for Captcha to work. It’s hard to know why.
