Php 在yii2中保存多条记录

我有一个数组，但保存记录时只保存最后一条记录

这是我的密码

        if (isset($arr["transporters"])) {

           foreach ($arr["transporters"] as $other) {
                $model->company_name = $other["transportername"];
                if($model->save()){
                $allsaved = true;
                 }

            }
            if($allsaved){
                return ['data' => "Successifully created"];
            }else{
                return ['data' => "Sorry an error occured when saving the transporters"];
            }
        }

通过

var\u dump（$arr）

它回来了

array(1) {
 ["transporters"]=>
 array(2) {
  [0]=>
   array(1) {
    ["transportername"]=> string(2) "news"  //its not saved
  }
  [1]=>
   array(1) {
     ["transportername"]=> string(4) "event"  //only this one gets saved
   }
 }
}

为什么我不能保存多条记录

添加一个合适的新模型，并正确地进行上传

  if (isset($arr["transporters"])) {

       foreach ($arr["transporters"] as $other) {
            $model = new YourModel(); // add new model 
            $model->company_name = $other["transportername"];
            ..... 
            $model->others_column  // remdeber to properly populated  with all the value you needd
            .......
            if($model->save()){
            $allsaved = true;
             }

        }
        if($allsaved){
            return ['data' => "Successifully created"];
        }else{
            return ['data' => "Sorry an error occured when saving the transporters"];
        }
    }

在这种情况下，每次要保存不同的数据库行时，都需要在循环中创建

$model

的新实例。我发现它现在可以工作了
