HomeBackend DevelopmentPHP TutorialYii2如何批量添加数据_PHP

批量添加这个操作,在实际开发中经常用得到,今天小编抽空给大家整理些有关yii2批量添加的问题,感兴趣的朋友一起看看吧。

在上篇文章给大家介绍了关于浅析Yii2 gridview实现批量删除教程,当然,着重点在于怎么去操作gridview了,今儿我们来好好谈谈yii2如何批量添加数据?

有同学嚷嚷了,这还不简单,我foreach一循环,每个循环里面直接把数据插入到数据库,简单粗暴完事!我擦嘞,哥,你要是跟我在一个公司,我觉得第二天见到你的概率可就不大了!

话不多说,说多了你在骂我,我们步入正题,先看一个简单到小学生都认识的表结构

//test 
id 
name

我们现在就是要在yii2中对这张数据表批量插入10条数据

我们想要的方式肯定是下面这样的,一条sql多么干脆直接了事

insert into test (name) values ('zhangsan'), ('lisi');

分析都分析完了,好吧,赶紧看看具体实现

//假如 $names = ['zhangsan', 'lisi']; 
$data = []; 
foreach ($names $k => $v) { 
$data[] = [$v]; 
} 
Yii::$app->db->createCommand()->batchInsert('test', ['name'], $data)->execute();

我相信很多人都是冲着AR能不能实现批量插入来的,理由无非就是更安全更方便操作呗。但是官方手册貌似没有,没有,没有。。。心都碎了,竟然没有,至少我没有找到,你找到了请点击原文找到我并联系我,我也si分的需要方法啊。

不过不巧的是,我找到一个跟AR相关联的操作方法,我们共同分享参考一下看看具体怎么回事

假设有一个Post类的数组 $models,你就可以这样操作

use yii\helpers\ArrayHelper; 
$rows = []; 
foreach ($models as $model) {
if ($model->validate()) { 
$rows[] = $model->attributes;
} 
} 
$rows = ArrayHelper::getColumn($models, 'attributes'); 
$postModel = new Post; 
Yii::$app->db->createCommand()->batchInsert(Post::tableName(), $postModel->attributes(), $rows)->execute(); 
//当然啦,上面给出的是插入所有的字段,但事实往往事与愿违,也简单,稍作调整即可 
$rows[] = [ 
'title' => $model->title, 
'content' => $model->content, 
]; 
Yii::$app->db->createCommand()->batchInsert(Post::tableName(), ['title', 'content'], $rows)->execute();

虽然又回到了batchInsert上,不过没关系,该验证的都验证了,安全是无须担心的。

以上所述是小编给大家介绍的Yii2如何批量添加数据的相关知识,希望对大家有所帮助!
