我目前正在从事一个项目，该项目的最终目标是能够创建一个网页，您可以在该网页中从excel文件中写入数据库而不会影响原始文件。当我在页面上书写时，它会写在数据库中，但是保存后原始的excel文件不会更改。 我正在按照该教程进行操作，有时，我被要求将以下脚本放置在phph文件中：
<?php
$req = $bdd->prepare('INSERT INTO [dbo].[T_PRODUIT_PRO]([SCA_ID], [PRO_CODE], [PRO_LIBELLE], [PRO_PRIX], [PRO_REFERENCE], [PRO_DESCRIPTION1], [PRO_DESCRIPTION2], [PRO_LIBELLE2], [ESB_ID], [TBR_ID], [FPL_ID], [PRO_APARTIR_DE], [PRO_DESCRIPTION_DETAILLEE1], [PRO_DESCRIPTION_DETAILLEE2])');
$req->execute(array(
'id' => $id,
'code' => $code,
'libelle' => $libelle,
'prix' => $prix,
'reference' => $reference,
'description1' => $description1,
'description2' => $description2,
'libelle2' => $libelle2,
'esbid' => $esbid,
'prix' => $prix,
'tbrid' => $tbrid,
'fplid' => $fplid,
'apartirde' => $apartirde,
'descriptiondetaille' => $descriptiondetaille,
'descriptiondetaille2' => $descriptiondetaille2,
));
echo 'The file has been added';
?>
因此，我为此更改了控制器：
<?php
// src/Controller/DefaultController.php
// src/Controller/Readfile.php
namespace App\Controller;
//require 'vendor/autoload.php';
use App\Entity\Product;
use App\Form\ProductType;
use PhpOffice\PhpSpreadsheet\Reader\Csv;
use PhpOffice\PhpSpreadsheet\Spreadsheet;
use PhpOffice\PhpSpreadsheet\Reader\Xlsx;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\HttpFoundation\RedirectResponse;
use Symfony\Bundle\FrameworkBundle\Controller\Readfile;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\File\Exception\FileException;
class DefaultController extends AbstractController
{
public function index()
{
return $this->render('Advert/index.html.twig');
}
public function upload()
{
return $this->render('Advert/form.html.twig');
}
public function bdd()
{
return $this->render('Advert/write.html.twig');
}
public function submit() {
$file_mimes = array('text/x-comma-separated-values', 'text/comma-separated-values', 'application/octet-stream', 'application/vnd.ms-excel', 'application/x-csv', 'text/x-csv', 'text/csv', 'application/csv', 'application/excel', 'application/vnd.msexcel', 'text/plain', 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
if(isset($_FILES['file']['name']) && in_array($_FILES['file']['type'], $file_mimes)) {
$arr_file = explode('.', $_FILES['file']['name']);
$extension = end($arr_file);
if('csv' == $extension) {
$reader = new \PhpOffice\PhpSpreadsheet\Reader\Csv();
} else {
$reader = new \PhpOffice\PhpSpreadsheet\Reader\Xlsx();
}
$spreadsheet = $reader->load($_FILES['file']['tmp_name']);
$sheetData = $spreadsheet->getActiveSheet()->toArray();
print_r($sheetData);
//return $this->render('Advert/write.html.twig');
}
}
/**
* @Route("/product/new", name="app_product_new")
*/
public function nouveau(Request $request)
{
$product = new Product();
$form = $this->createForm(ProductType::class, $product);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
// $file stores the uploaded PDF file
/** @var Symfony\Component\HttpFoundation\File\UploadedFile $file */
$file = $product->getBrochure();
$fileName = $this->generateUniqueFileName().'.'.$file->guessExtension();
// Move the file to the directory where brochures are stored
try {
$file->move(
$this->getParameter('brochures_directory'),
$fileName
);
} catch (FileException $e) {
// ... handle exception if something happens during file upload
}
// updates the 'brochure' property to store the PDF file name
// instead of its contents
$product->setBrochure($fileName);
// ... persist the $product variable or any other work
return $this->redirect($this->generateUrl('app_product_list'));
}
return $this->render('product/new.html.twig', [
'form' => $form->createView(),
]);
}
/**
* @return string
*/
private function generateUniqueFileName()
{
// md5() reduces the similarity of the file names generated by
// uniqid(), which is based on timestamps
return md5(uniqid());
}
}
我也为我服务：
# This file is the entry point to configure your own services.
# Files in the packages/ subdirectory configure your dependencies.
# Put parameters here that don't need to change on each machine where the app is deployed
# https://symfony.com/doc/current/best_practices/configuration.html#application-related-configuration
parameters:
brochures_directory: '%kernel.project_dir%/public/uploads/brochures'
services:
# default configuration for services in *this* file
_defaults:
autowire: true # Automatically injects dependencies in your services.
autoconfigure: true # Automatically registers your services as commands, event subscribers, etc.
# makes classes in src/ available to be used as services
# this creates a service per class whose id is the fully-qualified class name
App\:
resource: '../src/*'
exclude: '../src/{DependencyInjection,Entity,Migrations,Tests,Kernel.php}'
# controllers are imported separately to make sure services can be injected
# as action arguments even if you don't extend any base controller class
App\Controller\:
resource: '../src/Controller'
tags: ['controller.service_arguments']
# add more service definitions when explicit configuration is needed
# please note that last definitions always *replace* previous ones
App\Controller\test\:
resource: '../src/Controller/script.php'
tags: ['controller.service_arguments']
和路径：
#app_test_page:
# path: /test
# controller: App\Controller\DefaultController::index
hello_the_world:
path: /home
controller: App\Controller\DefaultController::index
upload_fichier:
path: /upload_file
controller: App\Controller\DefaultController::upload
submit_fichier:
path: /read_file
controller: App\Controller\DefaultController::submit
submit_fichier:
path: /write_file
controller: App\Controller\DefaultController::bdd
所有这些，当我尝试运行命令“ php bin / console server：run”时遇到的错误是：
In FileLoader.php line 166:
Notice: Undefined variable: bdd in C:\xampp\htdocs\importservicesetproduits\config/services.yaml (which is loaded in resource "C:\xampp\htdocs\importservicesetproduits\config/services.yaml").
In script.php line 2:
Notice: Undefined variable: bdd
如果您需要查看项目的特定页面，请告诉我，我将向您展示，但是我的问题是：我该如何解决我的问题？而且，如果您对我的项目有更多的想法，除此以外，我还有什么要做的事情吗？
