Come together with the global Drupal community in Rotterdam, 28 Sept – 1 Oct 2026. Sessions, contribution, connection, and Early Bird savings until 8 June.I'm using Captcha+Riddler, and it appears to be case sensitive.
Quick-fix...
I think it may be line 221 in captcha.module:
if($value == $_SESSION['captcha'][$seed]['value']) {
to something like:
if (! strcasecmp($value, $_SESSION['captcha'][$seed]['value'])) {
and it works for now, till I figure out how to call that function from Riddler instead of altering it in Captcha.

imerlin commentedThis fix is specific to the Captcha module. I'm not aware of any way to enforce this through Riddler except try to pre-validate the form before Captcha does, but that kind of defeats the purpose of using Captcha for this.
Unfortunately the only information I pass on from the Riddler module is the expected answer and right now, that is case sensitive.
I've forwarded the issue to the Captcha project, maybe there's a possibility of adding a case option to Captcha or a way for Captcha extensions to set it themselves.

robloachSometimes you're not comparing strings there, and usually Captchas are case-sensitive. Captcha Riddler could, however, preprocess the validation to have complete control over how the validation goes over.
