Yii2-观点给了我错误提交一个excel文件后Yii2-观点给了我错误提交一个excel文件后(Y

我的工作Yii2 。我在导入Excel文件。虽然在导入我也发送id以前的模型。过程如下

用户打开GUI，并从下拉列表中选择一些值，然后点击创建按钮。

创建控制器

 public function actionCreate()
  {
    $model = new MeterAcceptanceHeader();
    $model->prepared_by = Yii::$app->user->id;
    $model->prepared_at = date('Y-m-d H:i:s');

    if ($model->load(Yii::$app->request->post()) && $model->save()) {
        return $this->redirect(['excel','id'=>$model->id]);
    } else {
        return $this->render('create', [
            'model' => $model,
        ]);
    }
}

点击下一步按钮后，用户会提示一个新的窗口，要求他上传的Excel文件。

Excel的控制器

 public function actionExcel($id){ $file_name = "excel_" . Yii::$app->user->id . ".xlsx"; $error = ""; if(isset($_FILES['file'])) { $path_parts = pathinfo($_FILES["file"]["name"]); $extension = $path_parts['extension']; if(!in_array($extension,['xlsx','xls'])){ $error = "Invalid file"; }else { if (move_uploaded_file($_FILES['file']['tmp_name'], 'uploads/' . $file_name)) { $this->redirect([ 'process', 'file_name' => $file_name, 'header_no' => $_POST['header_no'], 'id'=>$id ]); } } } return $this->render("excel",['error'=>$error,'id'=>$id]); }

Excel检视

  <div class="box-body"> <?php if($error != ""){?> <div class="alert alert-danger"><?=$error?></div> <?php } ?> <form action="" method="post" enctype="multipart/form-data"> <input type="hidden" name="_csrf" value="<?= Yii::$app->request->getCsrfToken() ?>"/> <input id="btn" class="form-control" type="file" name="file" /> <div class="form-group"> <br /> Header Row <br /> <select name="header_no" class="form-control"> <option value="1">1</option> <option value="2">2</option> <option value="3">3</option> <option value="4">4</option> <option value="5">5</option> <option value="6">6</option> <option value="7">7</option> <option value="8">8</option> </select> <br /> <input type="submit" value=" Next " class="btn btn-primary" /> </div> </form> </div>

上传Excel文件中的用户后会点击下一步按钮
现在，在这个窗口的用户将被要求地图数据库领域的Excel领域

过程控制器

 public function actionProcess(){

    $file_name = $_GET['file_name'];
     $id = $_GET['id'];

    try {
        $header_index = $_GET['header_no'];

        $data = \moonland\phpexcel\Excel::widget([
            'mode' => 'import',
            'fileName' => 'uploads/' . $file_name,
            'setFirstRecordAsKeys' => false, // if you want to set the keys of record column with first record, if it not set, the header with use the alphabet column on excel.
            'setIndexSheetByName' => false, // set this if your excel data with multiple worksheet, the index of array will be set with the sheet name. If this not set, the index will use numeric.
            'getOnlySheet' => 0, // you can set this property if you want to get the specified sheet from the excel data with multiple worksheet.

        ]);

        if (isset($data[0])) {
            $headers = $data[0][$header_index];
        } else {
            $headers = $data[$header_index];
        }

    }catch (Exception $x){
        print_r($x->errorInfo);
    }

    return $this->render('excel_options',['headers'=>$headers,'file_name'=>$file_name,'header_index'=>$header_index,'id'=>$id]);

}

Excel选项查看

上述观点被称为在process动作控制器。而在该图中，我传递模型ID作为隐藏字段。

映射文件，并点击提交按钮后，文件中的数据将被保存到数据库中。下面是导入操作，将数据保存到数据库中

 public function actionImport() { $file_name = $_POST['file_name']; $header_index = $_POST['header_index']; $fieldSet = $_POST['field']; $model_id = $_POST['model_id']; print_r($model_id); die(); . . . return $this->render('excel_finish', ['records_saved' => $ok_count,'status_arr'=>$status_arr]); }

什么到目前为止，我已经做了

我能够从用户（包括Excel文件），选择数据。映射后，它应该对进口行动，但我得到以下错误
