php - texto - No se pudo encontrar el archivo al usar LifecycleCallbacks

string strip_tags

Question

Tengo un problema con la form validation en symfony2 .

En mi caso, el comando $form->isValid() da como resultado The file could not be found. a pesar de que proporciono un archivo durante el llenado del formulario

Además, la setFile función setFile en la documents entity lleva a la conclusión de que el valor del archivo está configurado correctamente. La función setFile y los resultados de print_r se proporcionan a continuación:

/**
* 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'';
}
}

resultado de print_r:

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 ) 

Mi pregunta es por qué a pesar de que el archivo se proporciona correctamente, el validador de formulario falla?

Cuando comente una parte de mi función setFile() , comienza a funcionar y se produce una excepción de movimiento.

''

/**
* 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'';
}*/
}

Mi clase de formulario:

<?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"))
;
}

Mi controlador en el cual la función is_valid resulta en resultado negativo:

 /**
* 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()) {

Answer 1

He descubierto cuál es el problema. He marcado la columna "enlace" como un archivo y, por lo tanto, el validador fallaba porque el enlace era texto y no un archivo.

Mi código de enlace fue:

/**
* @ORM/Column(type="string", length=220)
* @Assert/File(maxSize="6000000")
*/
protected $link;

y la línea:

 * @Assert/File(maxSize="6000000")

no debería estar allí.
