                  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]
                     ];
                  }
                  

                • 检查 $bulkInsertArray 是否为空

                • Check $bulkInsertArray in not empty

                  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.

                  Hope these code may be helpful.
