session error in codeigniter?
Sharing a solution that helped me, try set your config variable like:
$config['sess_save_path'] = sys_get_temp_dir();
This error comes when we use directory bases session approach in CodeIgniter. If we use database based session approach error will go. Use code below -
change your application->config->config.php and set
$config['sess_driver'] = 'database';$config['sess_cookie_name'] = 'ci_session';$config['sess_expiration'] = 7200;$config['sess_save_path'] = 'ci_sessions';$config['sess_match_ip'] = FALSE;$config['sess_time_to_update'] = 300;$config['sess_regenerate_destroy'] = FALSE;& Run SQL query
CREATE TABLE IF NOT EXISTS `ci_sessions` ( `id` varchar(40) NOT NULL, `ip_address` varchar(45) NOT NULL, `timestamp` int(10) unsigned DEFAULT 0 NOT NULL, `data` blob NOT NULL, PRIMARY KEY (id), KEY `ci_sessions_timestamp` (`timestamp`));
In config.php sess_save_path should be sys_get_temp_dir(); then it will resolve the error of mkdir(): Invalid path
