Adobe Exam AD0-E716 Topic 11 Question 46 Discussion

To display the 'file upload' field and process the actual CSV import, the following two requirements must be met:

The developer must create a new system configuration setting that specifies the path to the CSV file.

The developer must create a new controller action that handles the file upload and import process.

The system.xml file is used to define system configuration settings. The following XML snippet shows how to define a new system configuration setting for the CSV file path:

XML

<config>

<system>

<config>

<shipment_fees_csv_path>/path/to/csv/file</shipment_fees_csv_path>

</config>

</system>

</config>

The ControllerAdminhtmlShipmentFees controller class is used to handle the file upload and import process. The following code shows how to create a new controller action that handles the file upload and import process:

PHP

public function uploadAction()

{

$file = $this->getRequest()->getFile('shipment_fees_csv_file');

if ($file->isUploaded()) {

$importer = new ShipmentFeesImporter();

$importer->import($file);

}

return $this->redirect('adminhtml/system_config/edit/section/shipment_fees');

}
