strange form validation pb

[skandaboy]

Hello,

I have a strange pb with my form for uploading image files that I dont understand. I try to upload images and create thumbnails from the uploaded files.

for example I have this definition for my form :

$builder->add('image', 'file'); (in my ImageType) with a good Class/object Image theres no pb to render the form

in my Controller I have :

Code: Select all

...some code

$image= new Image();
$formImage= $this->createForm(new ImageType(), $image);       
if ($request->getMethod() == 'POST' ) {
            $formImage->bindRequest($request);             
                $image = $formImage['image']->getData();
                $response = $this->forward('PkTestBundle:CreateImage:index', array('img' => $image));
                return $response;
..some code


Everything works fine, it uploads files and creates the thumbnails but if I try to check if the form is valid :

Code: Select all

...some code
if ($request->getMethod() == 'POST' ) {
            $formImage->bindRequest($request); 
            if ($formImage->isValid()){                 <-line added
                $image = $formImage['image']->getData();
                $response = $this->forward('PkTestBundle:CreateImage:index', array('img' => $image));
                return $response;
            }
          else throw $this->createNotFoundException('form invalid);   <-line added
..some code


It doesn't work! I have the Exception message 'form invalid'. I retired the line 'if ($formImage->isValid())'. its not normal that in one case it works and in the other case it doesn't while its exactly the same form.
Can someone explain me why? I miss something?
thanks

Hard to tell without seeing the image class' validation constraints.

well actually I changed the form declaration to this :
$formImage = $this->createFormBuilder()->add('image', 'file')->getForm();

and the controller :

Code: Select all

...
if ($request->getMethod() == 'POST') {
                    $formImage->bindRequest($request); 
                    if ($formImage->isValid()) {
                    $image = $formImage['image']->getData();
                    $response = $this->forward('PkTestBundle:CreateImage:index', array('img' => $image));
                    return $response;
                    }
                    else throw $this->createNotFoundException ('Formulaire invalid');
...


and still I have the exception message when I submit the form. So I dont get what happen
