How to use liuggio/ExcelBundle to post excel data to database - symfony

Question

Without Symfony, this is how I post excel data to database.
// Include PHPExcel_IOFactory
require_once ('../Classes/PHPExcel/IOFactory.php');
$inputFileName = 'abc.xls';
// Read your Excel workbook
try {
$inputFileType = PHPExcel_IOFactory::identify($inputFileName);
$objReader = PHPExcel_IOFactory::createReader($inputFileType);
$objPHPExcel = $objReader->load($inputFileName);
} catch(Exception $e) {
die('Error loading file "'.pathinfo($inputFileName,PATHINFO_BASENAME).'": '.$e->getMessage());
}
// Get worksheet dimensions
$sheet = $objPHPExcel->getSheet(0);
$highestRow = $sheet->getHighestRow();
$highestColumn = $sheet->getHighestColumn();
// Loop through each row of the worksheet in turn
for ($row = 1; $row <= $highestRow; $row++){
// Read a row of data into an array
$rowData = $sheet->rangeToArray('A' . $row . ':' . $highestColumn . $row,
NULL,
TRUE,
FALSE);
// Insert row data array into your database of choice here
}
Now with the ExcelBundle, I am stuck. The documentation doesn't help me at all in this task. I've tried every advice given in similar questions and I cant manage to do this.
Creating an object from a file like the example below doesn't work at all:
$phpExcelObject = $this->get('phpexcel')->createPHPExcelObject('file.xls');
How to achieve this task?

Answer 1

I worked this out as follows:
Make sure the path Liuggio/ExcelBundle/Controller/FakeController.php exists
Make sure you update the app/config config.yml and routing.yml are updated with the provided files (Liuggio/ExcelBundle/Tests/app)
Assuming that you are updating the product table, Update the FakeController as follows:
<?php
namespace Liuggio\ExcelBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Response;
use AppBundle\Entity\Product;
class FakeController extends Controller
{
public function insertAction()
{
$data = [];
$appPath = $this->container->getParameter('kernel.root_dir');
$file = realpath($appPath . '/../web/excelFiles/abc.xls');
$phpExcelObject = $this->get('phpexcel')->createPHPExcelObject($file);
$sheet = $phpExcelObject->getActiveSheet()->toArray(null, true, true, true);
$em = $this->getDoctrine()->getManager();
$data['sheet'] = $sheet;
//READ EXCEL FILE CONTENT
foreach($sheet as $i=>$row) {
if($i !== 1) {
$product = new Product();
$product->setProductCode($row['A']);
$product->setProductName($row['B']);
$product->setProductRetailPrice($row['C']);
$product->setProductCost($row['D']);
$product->setProductTax($tax);
$product->setCategory($category);
//... and so on
$em->persist($product);
$em->flush();
//redirect appropriately
}
}
$data['obj'] = $phpExcelObject;
return $this->render('excel/read.html.twig', ['data' => $data ] );
}
}
