I need help from someone smarter than I am... I'm loading Xenforo into a PHP page, and writing a new user to it. That part works fine. My code is: PHP: require($fileDir.'/library/XenForo/Autoloader.php'); XenForo_Autoloader::getInstance()->setupAutoloader($fileDir . '/library'); $startTime = microtime(true); XenForo_Application::initialize($fileDir . '/library', $fileDir); XenForo_Application::set('page_start_time', $startTime); XenForo_Application::disablePhpErrorHandler(); // create new user $writer = XenForo_DataWriter::create('XenForo_DataWriter_User'); // set all the values $writer->set('username', $strUsername); $writer->set('email', $Email); $writer->setPassword($strPassword, $strPassword); $writer->set('user_group_id', XenForo_Model_User::$defaultRegisteredGroupId); // save user $writer->save(); Here's the problem: Immediately after this above code executes, I want to insert a user into another xenforo forum, into a different xenforo install from the first. I tried repeating this same code again, pointing to the second xenforo install by specifying the second forum's file directory to variable $fileDir... but unfortunately, it gives me errors the second time around. It doesn't like to see this line a second time, right there that crashes the page: Code: require($fileDir.'/library/XenForo/Autoloader.php'); And when I remove that line of code and try different things, it still fails. My question is, how do I insert a user into one xenforo install, and then immediately into another xenforo install? Is this possible?
