无法将模型 ID 传递给视图

Question

我正在使用 yii2。我想将模型 ID 传递给视图，但这样做时出现错误。

控制器

public function actionProcess($id){
    try {
        $model = $this->findModel($id);
    } catch (NotFoundHttpException $e) {
    } // this will find my model/record based on the id
    $file_name = $_GET['file_name'];

    // $data = \moonland\phpexcel\Excel::import("uploads/test.xlsx"); // $config is an optional

    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'=>$model->id]);

}

在我看来，我正在尝试在提交按钮中传递模型 ID

 <div class="row">
                <div class="col-md-2"></div>

                <div class="col-md-4">
                    <br />
                    <a href="<?= URL::toRoute(['meteracceptanceheader/import', 'id'=>$model->id])?>" name="redirect" class="btn btn-primary" id="myid">Submit</a>
                </div>
            </div>

现在，当我尝试访问我的 excel_options 视图时，出现以下错误。

Undefined variable: model in E:\xampp\htdocs\inventory-web\backend\views\meteracceptanceheader\excel_options.php at line 103

<a href="<?= URL::toRoute(['meteracceptanceheader/import', 'id'=>$model->id])?>" name="redirect" class="btn btn-primary" id="myid">Submit</a>

我用来渲染 excel_options 的控制器在

下面

public function actionProcess($id){

        $model = $this->findModel($id);
     // this will find my model/record based on the id
    $file_name = $_GET['file_name'];

    // $data = \moonland\phpexcel\Excel::import("uploads/test.xlsx"); // $config is an optional

    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'=>$model->id]);

}

如何将我的模型 ID 传递到视图中？

任何帮助将不胜感激

Answer 1

尝试传递自己的 $model 而不是 id。

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

并让您的代码可见。

 <a href="<?= URL::toRoute(['meteracceptanceheader/import', 'id'=>$model->id])?>" name="redirect" class="btn btn-primary" id="myid">Submit</a>
