Unable to pass model id to view - php

Question

I am using yii2. I want to pass the model id to a view but while doing so I am getting an error.
Controller
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'=>$model->id]);
}
View
In my view, I am trying to pass the model id in a submit button
<div class="row">
<div class="col-md-2"></div>
<div class="col-md-4">
<br />
Submit
</div>
</div>
Now when I try to access my excel_options view, I am getting the below error.
Undefined variable: model
in E:\xampp\htdocs\inventory-web\backend\views\meteracceptanceheader\excel_options.php at line 103
Submit
Update 1
The controller from which I am rendering the excel_options is below
public function actionProcess($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]);
}

How can I pass my model id into the view?
Any help would be highly appreciated

Answer 1

Try to pass not id but $model it self.
return $this->render('excel_options',['headers'=>$headers,'file_name'=>$file_name,'header_index'=>$header_index,'model'=>$model]);
and Keep you code in view.
