Magento campo de formulario de carga de imágenes

Question

que siguieron this link para hacer el trabajo de carga de imágenes dentro de mi módulo de Magento, pero lo más grande que todo lo que hace es pasar el código de nombre de archivo seleccionado mediante POST: $_FILES matriz está vacía cada vez que agrego image o file campos.

Aquí está mi código:

<?php 
class Moo_News_Block_Adminhtml_News_Edit_Tab_Form extends Mage_Adminhtml_Block_Widget_Form 
{ 
    protected function _prepareForm() 
    { 
     $form = new Varien_Data_Form(); 
     $this->setForm($form); 
     $fieldset = $form->addFieldset('news_form', array('legend' => Mage::helper('news')->__('Item information'))); 

     $fieldset->addField('title', 'text', array(
      'label'  => Mage::helper('news')->__('Title'), 
      'class'  => 'required-entry', 
      'required' => true, 
      'name'  => 'title', 
     )); 

     $fieldset->addField('published', 'select', array(
      'label'  => Mage::helper('news')->__('Published'), 
      'name'  => 'published', 
      'required' => true, 
      'values' => array(
       array(
        'value'  => 1, 
        'label'  => Mage::helper('news')->__('Yes'), 
       ), 

       array(
        'value'  => 0, 
        'label'  => Mage::helper('news')->__('No'), 
       ), 
      ), 
     )); 

     $fieldset->addField('short_description', 'editor', array(
      'name'  => 'short_description', 
      'label'  => Mage::helper('news')->__('Short Description'), 
      'title'  => Mage::helper('news')->__('Short Description'), 
      'style'  => 'width:98%; height:200px;', 
      'wysiwyg' => false, 
      'required' => true, 
     )); 

     $fieldset->addField('body', 'editor', array(
      'name'  => 'body', 
      'label'  => Mage::helper('news')->__('Body'), 
      'title'  => Mage::helper('news')->__('Body'), 
      'style'  => 'width:98%; height:400px;', 
      'wysiwyg' => false, 
      'required' => true, 
     )); 


     $fieldset->addField('image', 'file', array(
      'label'  => Mage::helper('news')->__('Image'), 
      'required' => false, 
      'name'  => 'image', 
     )); 

     if (Mage::getSingleton('adminhtml/session')->getNewsData()) 
     { 
      $form->setValues(Mage::getSingleton('adminhtml/session')->getNewsData()); 
      Mage::getSingleton('adminhtml/session')->setNewsData(null); 
     } elseif (Mage::registry('news_data')) { 
      $form->setValues(Mage::registry('news_data')->getData()); 
     } 

     return parent::_prepareForm(); 
    } 
} 

y el código del controlador:

<?php 

/** 
* 
* 
*/ 

class Moo_News_Adminhtml_NewsController extends Mage_Adminhtml_Controller_Action 
{ 

    protected function _initAction() 
    { 
     $this->loadLayout() 
      ->_setActiveMenu('news/items') 
      ->_addBreadcrumb(Mage::helper('adminhtml')->__('Items Manager'), Mage::helper('adminhtml')->__('Item Manager')); 
     return $this; 
    } 

    public function indexAction() { 
     $this->_initAction(); 
     $this->_addContent($this->getLayout()->createBlock('news/adminhtml_news')); 
     $this->renderLayout(); 
    } 

    public function editAction() 
    { 
     $newsId  = $this->getRequest()->getParam('id'); 
     $newsModel = Mage::getModel('news/post')->load($newsId); 

     if ($newsModel->getId() || $newsId == 0) { 

      Mage::register('news_data', $newsModel); 

      $this->loadLayout(); 
      $this->_setActiveMenu('news/items'); 

      $this->_addBreadcrumb(Mage::helper('adminhtml')->__('Item Manager'), Mage::helper('adminhtml')->__('Item Manager')); 
      $this->_addBreadcrumb(Mage::helper('adminhtml')->__('Item News'), Mage::helper('adminhtml')->__('Item News')); 

      $this->getLayout()->getBlock('head')->setCanLoadExtJs(true); 

      $this->_addContent($this->getLayout()->createBlock('news/adminhtml_news_edit')) 
       ->_addLeft($this->getLayout()->createBlock('news/adminhtml_news_edit_tabs')); 

      $this->renderLayout(); 
     } else { 
      Mage::getSingleton('adminhtml/session')->addError(Mage::helper('news')->__('Item does not exist')); 
      $this->_redirect('*/*/'); 
     } 
    } 

    public function newAction() 
    { 
     $this->_forward('edit'); 
    } 

    public function saveAction() 
    { 
     if ($this->getRequest()->getPost()) { 
      try { 
       $postData = $this->getRequest()->getPost(); 
       $newsModel = Mage::getModel('news/post'); 

       $imgFilename = NULL; 

       //if (isset($postData['image']) && $postData['image'] != '') { 
       //if (isset($_FILES['image']['name']) && $_FILES['image']['name'] != '') { 
       if (false) { 
        try { 
         $uploader = new Varien_File_Uploader('image'); 

         $uploader->setAllowedExtensions(array('jpg','jpeg','gif','png')); 
         $uploader->setAllowRenameFiles(false); 
         $uploader->setFilesDispersion(false); 

         // Set media as the upload dir 
         $media_path = Mage::getBaseDir('media'); 

         $imgFilename = $media_path . $postData['image']; 

         while (file_exists($filename)) { 
          $pieces = array(); 

          $res = preg_match('/^(.+)_(\d+)$/', $filename, $pieces); 

          if (!$res) { 
           $filename .= '_1'; 
          } else { 
           $filename .= '_' . strval(intval($pieces[2]) + 1); 
          } 
         } 

         // Upload the image 
         $uploader->save($media_path, $postData['image']); 
        } 
        catch (Exception $e) { 
         Mage::log($e); 
         $this->redirectError(502); 
        } 
       } else { 
        if(isset($postData['image']['delete']) && $postData['image']['delete'] == 1) { 
         $imgFilename = NULL; 
        } 
       } 

       if(isset($imgFilename)) 
        $newsModel->setImage($imgFilename); 

       $newsModel->setId($this->getRequest()->getParam('id')) 
        ->setTitle($postData['title']) 
        ->setBody($postData['body']) 
        ->setShortDescription($postData['short_description']) 
        ->save(); 

       Mage::getSingleton('adminhtml/session')->addSuccess(Mage::helper('adminhtml')->__('Item was successfully saved')); 
       Mage::getSingleton('adminhtml/session')->setNewsData(false); 

       $this->_redirect('*/*/'); 
       return; 
      } catch (Exception $e) { 
       Mage::getSingleton('adminhtml/session')->addError($e->getMessage()); 
       Mage::getSingleton('adminhtml/session')->setNewsData($this->getRequest()->getPost()); 
       $this->_redirect('*/*/edit', array('id' => $this->getRequest()->getParam('id'))); 
       return; 
      } 
     } 
     $this->_redirect('*/*/'); 
    } 

    public function deleteAction() 
    { 
     if($this->getRequest()->getParam('id') > 0) { 
      try { 
       $newsModel = Mage::getModel('news/post'); 

       $newsModel->setId($this->getRequest()->getParam('id')) 
        ->delete(); 

       Mage::getSingleton('adminhtml/session')->addSuccess(Mage::helper('adminhtml')->__('Item was successfully deleted')); 
       $this->_redirect('*/*/'); 
      } catch (Exception $e) { 
       Mage::getSingleton('adminhtml/session')->addError($e->getMessage()); 
       $this->_redirect('*/*/edit', array('id' => $this->getRequest()->getParam('id'))); 
      } 
     } 
     $this->_redirect('*/*/'); 
    } 
    /** 
    * Product grid for AJAX request. 
    * Sort and filter result for example. 
    */ 
    public function gridAction() 
    { 
     $this->loadLayout(); 
     $this->getResponse()->setBody(
       $this->getLayout()->createBlock('importedit/adminhtml_news_grid')->toHtml() 
     ); 
    } 
} 

Entonces, la pregunta es: ¿cómo debo hacer esto de una manera correcta?

Answer 1

El truco consistía en cambiar el código de creación de formulario predeterminado

$form = new Varien_Data_Form(array(
    'id' => 'edit_form', 
    'action' => $this->getUrl('*/*/save', array('id' => $this->getRequest()->getParam('id'))), 
    'method' => 'post', 
)); 

a

$form = new Varien_Data_Form(array(
    'id' => 'edit_form', 
    'action' => $this->getUrl('*/*/save', array('id' => $this->getRequest()->getParam('id'))), 
    'method' => 'post', 
    'enctype' => 'multipart/form-data' 
)); 

No

dentro del código que he proporcionado, pero dentro de la persona que llama para ese parcial (..._Adminhtml_News_Edit_Form en lugar de ..._Adminhtml_News_Edit_Tab_Form)
