注册用户CRUD操作和其他操作

Question

我需要将所有活动注册到我的webapp中，例如当用户删除，添加或编辑某些记录和特定事件时。有任何想法吗？我使用codeigniter进行编程。

例如GLPI：

GLPI Events Table

这很简单。创建一个名为activity的模型并创建一个日志方法：

$this->activity->log("{$this->curr_user->name} logged in.");

我个人使用短代码和开关语句（如果你有很多活动，可能会变得非常笨重 - 不确定是否推荐）：

$this->activity->log('page_access', array('uri' => uri_string()));

或

$this->activity->log('modified', array('table' => $table, 'id' => $id));

这是我的活动模型：

class User_activity_model extends CI_Model {

    /**
     * Admin-only log types
     * 
     * @var array
     */
    private $admin_types = array('page_access', 'user_registered', 'logged_in', 'login_failed', 'login_failed_sa');

    /**
     * Main user activity logging function
     * 
     * @param string $action
     * @param array $arr Additional attributes per case
     * @return void
     */
    public function log($action, $arr = array()) {
        switch ($action) {
            default:
                return;
            case 'backup_created':
                $username = $this->curr_user->details()->username;
                $msg = "{$username} created a backup {$arr['filename']} at {time}.";
                break;
            case 'backup_restored':
                $username = $this->curr_user->details()->username;
                $msg = "{$username} restored backup {$arr['filename']} at {time}.";
                break;
            case 'user_registered':

                $msg = "{$username} added item {$arr['id']} to the {$arr['table']} table.";
                break;
