Uploading a file + hash gives me a problem when the size is larger than the maximum size

Question

I notice something strange and wondered if anyone could check my code on their side and let me know if they get the same thing.

I have a simple simple form (see the full form code and action code below), in which there is only a download button + hidden hash + submit button. The maximum size of the file installed in the file is 10,000,000 (about 9.5 MB).

When I try to upload a file that exceeds the limit, the form should not be checked, but I get an error in the hash mark itself Value is required and can't be empty. Can anyone confirm? It seems like the token is being destroyed. I assume that this can happen in the case of a redirect or something else, but I do not do any redirects if something does not happen in the background, which I do not notice.

Here is the form code and my action code

class Application_Form_TestForm extends Zend_Form
{

    public function init()
    {   

    $file = new Zend_Form_Element_File('file');
    $file->setDestination(APPLICATION_PATH);
    $file->addValidator('Size', false, 10000000);
    $file->setMaxFileSize(10000000);
    $this->addElement($file);

    $hash = new Zend_Form_Element_Hash('hash');
    $hash->setIgnore(true)
         ->setSalt('mysalt');
    $this->addElement($hash);  

    $submit = new Zend_Form_Element_Submit('submit');       
    $submit->setLabel('Test')
           ->setIgnore(true);            
    $this->addElement($submit);  

    $this->setAttrib('enctype', 'multipart/form-data');
    $this->setMethod('post');
}
}

In my controller I do a normal check

public function indexAction()
{
    $form = new Application_Form_TestForm();
    $this->view->form = $form;

    if($this->_request->isPost()){          
        echo "post";
        if($form->isValid($this->_request->getPost())){
           echo " valid";
        }
    }

}

This is similar to your post_max_size or upload_max_filesize values ​​in your php.ini. For example, the default value of post_max_size is 8M, which is less than your maximum file size.
