PHP Session
The grid header displays, but then an error is presented:
Notice: Undefined index: _oPHPGRID_tablename_sql in /home/hcw/public_html/phpGrid/data.php(1) : eval()'d code on line 1
Notice: Undefined index: _oPHPGRID_tablename_sql_key in /home/hcw/public_html/phpGrid/data.php(1) : eval()'d code on line 1
....
Solution:The error is caused by a PHP session issue. Make sure PHP Session is enabled and set to a valid directory. Use phpinfo() to view your PHP configuration. Be sure that session.save_path is set to a valid path that exists and is writable by your web server. In Linux, by default, the path is usually /var/php_sessions/
In addition, session.auto_start should be set to
off or 1. If sessions auto-start and you try to store objects in sessions, PHP needs to know about the class definitions before the session startsj. This can cause errors when unserializing objects. phpGrid starts sessions automatically when loading using session_start() if session has not started yet. Some web hosting services such as iPage, disallows shared user session folder for security reasons. Users MUST create and maintain their own session folder.
