Validation is always firing rule message

Question

My validation for my image upload is always firing the message related with the allowed size for the file to be uploaded, after I copied the code to the top of the validation array where previouslly was the is_valid rule, which was being always triggered as well, even when the file size is lower than the limit and even when the file is uploaded successfully. My is_unique rule is working as expected but the rest seem to be always triggered even when the files obey the rules .What is triggering this behaviour? I am using CakePHP 2.4.4.

Controller

public function admin_upload_image(){
        $this->set('title_for_layout', 'Inserir Fotografias');
        if(!$this->Session->check('User')) {
            $this->Session->setFlash('Está a aceder a uma zona restrita. Por favor faça Login.');
            $this->redirect(array(
                            'controller' => 'users',
                            'action' => 'login'));
        }

        $this->layout = 'admin_index';
        if($this->request->is('post') || $this->request->is('put')) {
          /*  $file = $this->request->data['gallery_images']['path']['name'];*/
       //debug($this->request->data['gallery_images']['path']['name']);
       //die;
        $file = array(
                'GalleryImage' => array(
                'path' => $this->request->data['gallery_images']['path']['name']
                                        )
                );
            move_uploaded_file($this->data['gallery_images']['path']['tmp_name'], $_SERVER['DOCUMENT_ROOT'] . '/html/PushUp/app/webroot/img/gallery/' . $this->data['gallery_images']['path']['name']);

            $this->loadModel('GalleryImage');

            $this->GalleryImage->create();
           //debug($file);
           //die;
            if($this->GalleryImage->save($file)){
                $validationErrors = $this->GalleryImage->invalidFields();
                $this->Session->setFlash($validationErrors['path']); // named key of the rule
                $this->Session->setFlash('Fotografia guardada com sucesso.', 'default', array('class'=>'alert alert-success'));
            }
            //else{
                //debug($this->GalleryImage->invalidFields());
                //die;
                //$error = $this->Notification->validationErrors;
                //$this->set('error', $error);

                //$this->Session->setFlash(__($error), 'Flash/warning');
            //}
        }
    }

Answer 1

You are passing the $file variable to be save $this->GalleryImage->save($file)

and you are setting this variable value manually

$file = array(
          'GalleryImage' => array(
          'path' => $this->request->data['gallery_images']['path']['name']
      )
);

so you are not passing file information to your model. you have to pass $this->request->data['gallery_images']['path'] to your save method
