Yii2-视图提交Excel文件后给我错误

我正在研究Yii2。我正在导入Excel文件。导入时,我还发送了先前模型的id。该过程如下

  1. 用户打开GUI并从下拉菜单中选择一些值,然后单击“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,
        ]);
    }
}
  1. 单击下一个按钮后,将提示用户到一个新窗口,要求他在其中上传一个excel文件。

    Excel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视图

      <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>
    
  2. 上传excel文件后,用户将单击“下一步”按钮

  3. 现在将在此窗口中要求用户将excel字段与DB字段映射起来

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选项视图

     <form action="import" method="post">
      <input type="hidden" name="file_name" value="<?=$_GET['file_name']?>" />
            <input type="hidden" name="header_index" value="<?= $_GET['header_no'] ?>"/>
            <input type="hidden" name="model_id" value="<?= $_GET['id'] ?>"/>

                </div>
            </div>
        </form>

以上视图在process动作控制器中调用。在此视图中,我将模型ID传递为隐藏字段。

  1. 映射文件并单击提交按钮后,文件中的数据将保存到数据库中。下面是导入操作,它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]);
    }
    

我到目前为止所做的事情

我能够从用户中选择数据(包括excel文件)。映射后,它应该转到导入操作,但是我遇到了错误

  

未找到(#404)   找不到页面。

URL: http://localhost:225/inventory-web/backend/web/meteracceptanceheader/process/import

enter image description here

更新1

在浏览器中检查元素时,我可以看到model id

我一定在做我不知道的错误。

任何帮助将不胜感激。

答案 0 :(得分:1)

此错误“未找到(#404)页面。”意味着它无法解析您从指定URL发出的请求。您的情况是:

http://localhost:225/inventory-web/backend/web/meteracceptanceheader/process/import

假设应该是这样的:

http://localhost:225/inventory-web/backend/web/meteracceptanceheader/import

查看本指南,了解如何在Yii2中处理请求,以及如何使用“ UrlHelper”为您的应用生成Urls。

答案 1 :(得分:0)

您确定通过帖子$file_name = $_POST['file_name']获得文件名吗?

只需尝试var_dump($_FILE)变量。

使用此文件,您将获得文件名$_FILES["file_name"]["name"]
