public function updateArticle(Request $request, $id) { $article = Article::findOrFail($id); $article->title = $request->input('title'); $article->content = $request->input('content'); $article->save(); return redirect()->back()->with('success', 'Article updated successfully!'); }
public function updateArticle(int $id, Request $request, EntityManagerInterface $entityManager) { $article = $entityManager->getRepository(Article::class)->find($id); if (!$article) { throw $this->createNotFoundException('No article found for id '.$id); } $article->setTitle($request->request->get('title')); $article->setContent($request->request->get('content')); $entityManager->flush(); return $this->redirectToRoute('article_show', [ 'id' => $article->getId() ]); }In this example, we are using the Symfony framework to update an article. We first retrieve the article from the database using its ID. We then update the title and content fields using the input data from the form. Finally, we use EntityManagerInterface to save the changes to the database and redirect the user to the updated article page. Package library that can be used for the updateArticle method in PHP could be Doctrine ORM, which is a powerful PHP library for database abstraction and object-relational mapping.
