php - Zend Form File upload won't validate or upload files -

i'm trying file upload zend form, cannot file uploads work.

here's form code:

public function __construct($options = null)     {         parent::__construct($options);         $this->setname('modelupload');         $this->setmethod('post');         $this->setaction('/model/upload');         $this->setattrib('enctype', 'multipart/form-data');          // ... other elements ... //          $file = new zend_form_element_file('file');         $file             ->setattrib('title', 'select file upload.')             ->setattrib('required',"")             ->setrequired(true)             ->addvalidator('count',false,1)             ->addvalidator('size',false,104857600)             ->setmaxfilesize(104857600)             ->setvaluedisabled(true)             ->setdestination(application_path . "/../data/models/temp/")             ->setlabel('select file upload.');          $submit = new zend_form_element_submit('submit', array(               'label' => 'upload'           ));         $submit->removedecorator('dtddwrapper');          $this->setdecorators( array( array('viewscript',         array('viewscript' => 'formviews/_form_upload_model.phtml'))));          $this->addelements(array($name, $description, $file, $submit));     } 

and here controller code:

public function uploadaction() {     // action body     error_reporting(e_all);     $this->view->pagetitle = "model upload";      $form = new application_model_formmodelupload();      if ($this->_request->ispost()) {         $formdata = $this->_request->getpost();         if ($form->isvalid($formdata)) {             echo "<h1>valid</h1>";              $upload = new zend_file_transfer();             $files  = $upload->getfileinfo();              $form->getvalues();          } else {             echo "<h1>not valid</h1>";         }         echo "<pre>";         print_r($formdata);         echo "</pre>";     }      $this->view->form = $form; } 

and when try , upload something, this:

not valid array (     [name] => title     [description] => description     [max_file_size] => 104857600     [file] => filename.extension     [submit] => upload ) 

i.e form not passing validation , have no idea why. aside this, file isn't being uploaded. i've tried many things , i'm @ wit's end. i'm using zend server ce on local environment if makes difference.

i thank in advance can offer!

edit:

tried miss poo's code below , got this:

array ( ) array (     [name] => array         (         )      [description] => array         (         )      [file] => array         (         )      [submit] => array         (         )  ) array ( ) 

absolutely no errors being returned...

i had same issee, when removed setmaxfilesize(104857600) form got error [fileuploaderrorinisize] => file 'image' exceeds defined ini size, had change php.ini config , add form enctype="multipart/form-data".
