[英]Lost old value file when edit form submit symfony2
我有一個帶有字段文件的編輯表單(項目),可以上傳圖片。 在我的數據庫中,我有一列“ img”來保存我的上傳圖片。
但是我想要用戶,如果他不上傳新圖片,他會得到舊的img。
我得到了帶有存儲庫的舊img:
public function editAction(Request $request, Projet $projet)
{
$editForm = $this->createForm('BBW\ProjetsBundle\Form\ProjetType', $projet);
$editForm->handleRequest($request);
$em = $this->getDoctrine()->getManager();
$repository = $em->getRepository('BBWProjetsBundle:Projet');
$old = $repository->findOneById($projet->getId()); // Données BDD Actuel
$old_img = $old->getImg();
var_dump( $old_img ); // Got the old name for img in database - Ex: img.png
if ($editForm->isSubmitted() && $editForm->isValid()) {
var_dump( $old_img ); // Got null img ..
$file = $projet->getImg(); // New File upload - Here got null img ( when i upload no file )
if( $file != null ){ // If i send an image - So the field img is not empty and got the new picture
// Want delete the old img - But not as i get the name of the old img, it doesn't remove
$fs = new Filesystem();
$fs->remove( $this->getParameter('uploads_dir_projets') . '/' . $old_img ); // old_img = null :(
$fileName = md5(uniqid()).'.'.$file->guessExtension();
$file->move( // Move new file, etc ..
$this->getParameter('uploads_dir_projets'),
$fileName
);
$projet->setImg( $fileName );
}else{
// In case i leave the field empty img - Here no new file is upload so file = null
// But When i submit the edit form,
// it replace the old value in database with null. I don't want it replace the old value if no new picture is upload
$projet->setImg( $old_img ); // Normally set the same name img
}
//$em->persist($projet);
//$em->flush();
//$request->getSession()->getFlashBag()->add('success', 'Projet modifié avec succès');
//return $this->redirectToRoute('bbw_projet_home');
}
return $this->render('BBWProjetsBundle:projet:edit.html.twig', array(
'projet' => $projet,
'edit_form' => $editForm->createView(),
));
}
我不知道該怎么辦:/非常感謝您的幫助。
檢查以下代碼:如果沒有要上傳的圖片,則舊值保持不變:
$projet = $editForm->getData();
if (isset($projet['file']) && $projet['file'] instanceof UploadedFile) {
if ($projet['file']->getError() == 0) {
$fileName = md5(uniqid()).'.'.$file->guessExtension();
// Move file...
$projet->setImg( $fileName );
} else {
// Report/track error
}
$em->persist($projet);
$em->flush();
}
