Yii框架记录后台操作日志

配置main.php

##在backend/config/main.php添加
#和components同级
'on beforeRequest' => function($event) {
        \yii\base\Event::on(\yii\db\BaseActiveRecord::className(),     
 \yii\db\BaseActiveRecord::EVENT_AFTER_UPDATE, ['common\models\TbLog', 'write']);##日志model和写日志静态方法
    },

配置日志model和写入方法

<?php
namespace common\models;
use Yii;
use yii\db\ActiveRecord;

class TbLog extends \common\models\BaseModel
{
    public static function tableName()
    {
        return "{{%tb_log}}";
    }

    public static function write($event)
    {
        // 排除日志表自身,没有主键的表不记录（没想到怎么记录。。每个表尽量都有主键吧，不一定非是自增id）
        if($event->sender instanceof \common\models\TbLog || !$event->sender->primaryKey()) {
            return;
        }
        $log_format = "修改 {%s} 由 {%s} 修改为 {%s}，";
        $cookie = \Yii::$app->request->cookies;
        $admin_id = $cookie->getValue('uid', 0);
        $admin_name = $cookie->getValue('name', '');
        // 显示详情有待优化,不过基本功能完整齐全
        if ($event->name == ActiveRecord::EVENT_AFTER_INSERT) {
            $description = "%s新增了表%s %s:%s的%s";
        } elseif($event->name == ActiveRecord::EVENT_AFTER_UPDATE) {
            $description = "%s修改了表%s %s:%s的%s";
        } else {
            $description = "%s删除了表%s %s:%s%s";
        }

        if (!empty($event->changedAttributes)) {
            $desc = '';
            foreach($event->changedAttributes as $name => $value) {
                if ($value == $event->sender->getAttribute($name)) {
                    continue;
                }
                $desc .= sprintf($log_format, $name,$value, $event->sender->getAttribute($name));
            }
            $desc = substr($desc, 0, -1);
        } else {
            $desc = '';
        }
        $userName = $admin_name;
        $tableName = $event->sender->tableSchema->name;
        $description = sprintf($description, $userName, $tableName, $event->sender->primaryKey()[0], $event->sender->getPrimaryKey(), $desc);
        $log = new TbLog();
        $log->admin_id = $admin_id;
        $log->admin_name = $admin_name;
        $log->info = $description;
        $log->create_time = time();
        $log->save();
    }
}

可以了，只需要两步，操作时就能自动增加没个对数据库的操作日志，自行测试日志是否增加吧
