connector.phpcurrently uses the PHP magic constant__FILE__to specify the current directory and then traverses up using thedirname()function to locateconfig.core.php.Our installation of MODX revolution has its resources directory outside the core directory, and includes it via a symlink instead, with the installation directory being
/srv/modx/revolution/$ ls -l /srv/modx/revolution/includes the following lines:... lrwxrwxrwx 1 apache apache 9 Feb 16 17:00 assets -> ../assets ... -rw-r--r-- 1 apache apache 101 Mar 19 15:15 config.core.php ...Since PHP 4.0.2,
__FILE__always contains an absolute path with symlinks resolved.In our particular case
__FILE__resolves to/srv/modx/assets/components/formsave.config.core.phpis found nowhere on that path (it's in/srv/modx/revolution/) soconnector.phpfails when trying to open the "view stored forms" component in MODX manager. The following message appears in the apache error log:[Sat Apr 12 18:48:58 2014] [error] [client <IP address removed>] PHP Fatal error: require_once(): Failed opening required '/srv/config.core.php' (include_path='.:/usr/share/pear:/usr/share/php') in /srv/modx/assets/components/formsave/connector.php.new on line 32, referer: <removed>A possible work-around is to copy
/srv/modx/revolution/config.core.phpto/srv/config.core.php.This patch replaces the use of
__FILE__with$_SERVER["SCRIPT_FILENAME"]as suggested in this StackOverflow question. I've tested this on MODX Revolution 2.2.13-pl (git) and it works without having to resort to copying config.core.php.Fixes #19
