问题描述

我想将当前系统时间添加到数据库中，同时将新记录插入数据库中，如time_created"列.yii2 不支持 PHP 的 time() 函数.我想要 yii2 特定的时间函数来帮助我保存当前时间戳.有人知道吗????

I want to add the current system time into database while inserting new record into database as in "time_created" column. PHP's time() function don't have support in yii2. I want yii2 specific time function that will help me save current timestamp. Anyone knows????

推荐答案

Yii 2 对此有特殊行为.只需将其附加到模型上即可.将此添加到您的模型到 behaviors() 方法:

Yii 2 has special behavior for this. Just attach it to the model. Add this to your model to behaviors() method:

use yii\behaviors\TimestampBehavior;
use yii\db\Expression;

public function behaviors()
{
    return [
        // Other behaviors
        [
            'class' => TimestampBehavior::className(),
            'createdAtAttribute' => 'time_created',
            'updatedAtAttribute' => false,
            'value' => new Expression('NOW()'),
        ],
    ];   
}
