Cannot Identify Non-Logged-In User

Similar issue here, only for me it just shows the regular Privacy Tools page when I click the link from the email. All that is shown is the “Please identify yourself via e-mail” field, no user data.

SOLVED IT!

This was caused by attempting to read $_COOKIE[‘gdpr_key’] in the same request as setcookie(‘gdpr_key’…); setcookie() does not update $_COOKIE until the next page load, so I added $_COOKIE['gdpr_key']=$email . '|' . $key; to the end of the setIdentificationCookie function in wp_content/plugins/gdpr-framework/src/DataSubject/DataSubjectAuthenticator.php as follows:-

    /**
     * Set the identification cookie with the given key
     *
     * @param $key
     */
    public function setIdentificationCookie($email)
    {
        $key = $this->dataSubjectIdentificator->generateKey($email);

        setcookie(
            'gdpr_key',
            $email . '|' . $key,
            time() + (15 * 60),
            COOKIEPATH,
            COOKIE_DOMAIN,
            false,
            true
        );
        
        $_COOKIE['gdpr_key']=$email . '|' . $key;
    }

I hope the plugin author fixes this in the next update so my edit doesn’t get overwritten.

Great work again, thanks for tracking down the issue. I wonder if this issue might depend on the environment as well, because this functionality is definitely working for us as well as many other users.

Will add the fix ASAP.

I think I jumped the gun. This edit made it work for a while but it is now behaving the way it was before. Most peculiar. I thought it might be something to do with caching but I don’t think that’s it either since the /privacy-tools/ page on our test site includes Cache-Control: max-age=0, private, no-store, no-cache, must-revalidate in the response header.

Update: The test site was using server side caching; after turning it off, the email link now works about 50% of the time, the other half giving the message about the link having expired – this is with SET_COOKE removed, so back to the original code.

Hi there!

Did you get this issue completely resolved? If so, what did you do exactly?
