在 Yii 2 中将多个数据插入数据库

问题描述

当我尝试将多个数据同时保存到数据库时，我的代码有问题，这是我保存到数据库中的代码:

I have problem with my code when i'm trying to save multiple data into database at the same time, this is my code to save into database:

foreach ($data as $value) {
   $model->route = $value[0][1];
   $model->begin_point = $value[0][2];
   $model->begin_point = $value[0][3];
   $model->save();
}
return $this->redirect('index');

每次我试图保存时，我只得到最后一个数据数组可以保存到数据库中.有人可以帮我吗?或者如果有人可以提供教程，那将是真正的帮助.

every i'm trying to save, i'm only get the last data array can save into database. could someone help me? or if someone could provide a tutorial, that would be a real help.

推荐答案

1. 通过循环多个值来创建一个数组.

1. Create an array by looping your multiple values.

$data- has multiple values
$bulkInsertArray = array();
foreach($data as $value){
   $bulkInsertArray[]=[
       'columnName1'=>$value[0][1],
       'columnName2'=>$value[0][2],
       'columnName3'=>$value[0][3]
   ];
}

if(count($bulkInsertArray)>0){
    $columnNameArray=['columnName1','columnName2','columnName3'];
    // below line insert all your record and return number of rows inserted
    $insertCount = Yii::$app->db->createCommand()
                   ->batchInsert(
                         $tableName, $columnNameArray, $bulkInsertArray
                     )
                   ->execute();
}

希望这些代码可能会有所帮助.
