codeigniter ci問題總結

codeigniter Message: mkdir(): Invalid path  Filename: drivers/Session_files_driver.php

緣由不明,解決辦法:

$config['sess_save_path'] = NULL;

改成

$config['sess_save_path'] = FCPATH.'public/sess_save_path';
//在根目錄下新建public/sess_save_path,並給寫文件權限

自動加載session報錯:

解決辦法:

$this->load->library('encryption');
$key = bin2hex($this->encryption->create_key(16));
echo $key;

生成key,$config['encryption_key'] = 'aab3162f9de3bdd00f7dd52662fed21d';
