I have problem with form validation in symfony2.
In my case the $form->isValid() command results in The file could not be found. even though that I provide a file during filling in the form
Additionally debuging of setFile function in documents entity leads to conclusion that file value is set correctly. The setFile function and results of print_r are provided below:
/**
* 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 result:
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 )
My questions is why even though the file is provided correctly the form validator fails?
When I comment out part of my setFile() function it starts to work resulting in move exception.
'
/**
* Sets 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 {

}
My form class:
<?php

use Symfony\Component\Form\AbstractType;

->add('file', 'file')
->add('notes', 'text', array('required' => "false"))

}
My controller in which is_valid function results in negative result:
