У меня проблема с form validation в symfony2 .
В моем случае команда $form->isValid() приводит к тому, что The file could not be found. хотя я предоставляю файл при заполнении формы
Кроме того, setFile функции setFile в documents entity приводит к выводу, что значение файла задано правильно. Функция setFile и результаты print_r приведены ниже:
/** * Sets file. * * @param UploadedFile $file */ public function setFile(UploadedFile $file = null) { $this->file = $file; print_r($this->file); // [THIS IS FOR TEST] // check if we have an old image path if (is_file($this->getAbsolutePath())) { // store the old name to delete after the update $this->temp = $this->getAbsolutePath(); } else { $this->link = 'initial'; } }
print_r результат:
Symfony\Component\HttpFoundation\File\UploadedFile Object ( [test:Symfony\Component\HttpFoundation\File\UploadedFile:private] => [originalName:Symfony\Component\HttpFoundation\File\UploadedFile:private] => firefox.exe [mimeType:Symfony\Component\HttpFoundation\File\UploadedFile:private] => application/octet-stream [size:Symfony\Component\HttpFoundation\File\UploadedFile:private] => 338032 [error:Symfony\Component\HttpFoundation\File\UploadedFile:private] => 0 [pathName:SplFileInfo:private] => C:\wamp\tmp\php9DC3.tmp [fileName:SplFileInfo:private] => php9DC3.tmp )
Мои вопросы – почему, несмотря на то, что файл предоставлен правильно, метод проверки формы не работает?
Когда я комментирую часть моей функции setFile() она начинает работать, в результате чего setFile() исключение перемещения.
'
/** * Sets file. * * @param UploadedFile $file */ public function setFile(UploadedFile $file = null) { $this->file = $file; /*if (is_file($this->getAbsolutePath())) { // store the old name to delete after the update $this->temp = $this->getAbsolutePath(); } else { $this->link = 'initial'; }*/ }
Мой класс формы:
<?php namespace AppBundle\Form; use Symfony\Component\Form\AbstractType; use Symfony\Component\Form\FormBuilderInterface; use Symfony\Component\OptionsResolver\OptionsResolverInterface; class DocumentsType extends AbstractType { /** * @param FormBuilderInterface $builder * @param array $options */ public function buildForm(FormBuilderInterface $builder, array $options) { $builder ->add('marker') ->add('document_date', 'date', array('widget' => 'single_text', 'format' => 'yyyy-MM-dd')) ->add('file', 'file') ->add('notes', 'text', array('required' => "false")) ; }
Мой контроллер, в котором функция is_valid приводит к отрицательному результату:
/** * This code is aimed at checking if the book is choseen and therefore whether any further works may be carried out */ $session = new Session(); if(!$session->get("App_Books_Chosen_Lp")) return new RedirectResponse($this->generateUrl('app_listbooks')); // Authorization goes here $documents = new Documents(); $form = $this->createForm(new DocumentsType(), $documents); $form->add('save', 'submit', array('label' => 'Dodaj dokument')); $form->handleRequest($request); if ($form->isValid()) {
Класс моих документов:
<?php namespace AppBundle\Entity; use Doctrine\ORM\Mapping as ORM; use Symfony\Component\Validator\Constraints as Assert; use Symfony\Component\HttpFoundation\File\UploadedFile; /** * @ORM\Entity * @ORM\HasLifecycleCallbacks * @ORM\Table(name="Documents") */ class Documents { /** * @ORM\Column(type="integer") * @ORM\Id * @ORM\GeneratedValue(strategy="AUTO") */ protected $id; /** * @ORM\ManyToOne(targetEntity="Books", inversedBy="documents") * @ORM\JoinColumn(name="book_id", referencedColumnName="id") */ protected $book; /** * @ORM\Column(type="string", length=220) */ protected $marker; /** * @ORM\Column(type="date", length=220) */ protected $document_date; /** * @ORM\Column(type="string", length=220) * @Assert\File(maxSize="6000000") */ protected $link; /** * @ORM\Column(type="text") */ protected $notes; /** * Get id * * @return integer */ public function getId() { return $this->id; } /** * Set marker * * @param string $marker * @return Documents */ public function setMarker($marker) { $this->marker = $marker; return $this; } /** * Get marker * * @return string */ public function getMarker() { return $this->marker; } /** * Set document_date * * @param \DateTime $documentDate * @return Documents */ public function setDocumentDate($documentDate) { $this->document_date = $documentDate; return $this; } /** * Get document_date * * @return \DateTime */ public function getDocumentDate() { return $this->document_date; } /** * Set link * * @param string $link * @return Documents */ public function setLink($link) { $this->link = $link; return $this; } /** * Get link * * @return string */ public function getLink() { return $this->link; } /** * Set notes * * @param string $notes * @return Documents */ public function setNotes($notes) { $this->notes = $notes; return $this; } /** * Get notes * * @return string */ public function getNotes() { return $this->notes; } /** * Set book * * @param \AppBundle\Entity\Books $book * @return Documents */ public function setBook(\AppBundle\Entity\Books $book = null) { $this->book = $book; return $this; } /** * Get book * * @return \AppBundle\Entity\Books */ public function getBook() { return $this->book; } /* * ### FILE UPLOAD PROCESS ### */ /** * @Assert\File(maxSize="6000000") */ private $file; /** * Stores temporay path */ private $temp; /** * Sets file. * * @param UploadedFile $file */ public function setFile(UploadedFile $file = null) { $this->file = $file; print_r($this->file); // [THIS IS FOR TEST] // check if we have an old image path if (is_file($this->getAbsolutePath())) { // store the old name to delete after the update $this->temp = $this->getAbsolutePath(); } else { $this->link = 'initial'; } } /** * @ORM\PrePersist() * @ORM\PreUpdate() */ public function preUpload() { if (null !== $this->getFile()) { $this->link = $this->getFile()->guessExtension(); } } /** * Get file. * * @return UploadedFile */ public function getFile() { return $this->file; } public function getAbsolutePath() { return null === $this->link ? null : $this->getUploadRootDir().'/'.$this->id.'.'.$this->link; } public function getWebPath() { return null === $this->link ? null : $this->getUploadDir().'/'.$this->link; } protected function getUploadRootDir() { // the absolute directory where uploaded // documents should be saved return __DIR__.'/../../../web/'.$this->getUploadDir(); } protected function getUploadDir() { // get rid of the __DIR__ so it doesn't screw up // when displaying uploaded doc/image in the view. return 'uploads/documents'; } /** * @ORM\PostPersist() * @ORM\PostUpdate() */ public function upload() { if (null === $this->getFile()) { return; } // check if we have an old image if (isset($this->temp)) { // delete the old image unlink($this->temp); // clear the temp image path $this->temp = null; } // you must throw an exception here if the file cannot be moved // so that the entity is not persisted to the database // which the UploadedFile move() method does $this->getFile()->move( $this->getUploadRootDir(), $this->id.'.'.$this->getFile()->guessExtension() ); $this->setFile(null); } /** * @ORM\PreRemove() */ public function storeFilenameForRemove() { $this->temp = $this->getAbsolutePath(); } /** * @ORM\PostRemove() */ public function removeUpload() { if (isset($this->temp)) { unlink($this->temp); } } }
