Varien_File_Uploader is not uploading files in custom module in magento - magento

Question

I am trying to save the images in my module but the images are not saving from the form.
$uploader = new Varien_File_Uploader('image'); this code is not working I dont know why. The loop breaks on this line and the control get out of the loop from here. How can I save the images.
Here is my save function in the controller
public function saveAction()
{
if ($this->getRequest()->getPost())
{
try
{
$postData = $this->getRequest()->getPost();
//echo "<pre>";print_r($postData); exit;
$articleModel = Mage::getModel('blog/article');
$imgFilename = NULL;
if($_FILES['image']['name'] != '')
{//echo "<pre>"; echo count($_FILES['image']['name']);
foreach($_FILES['image']['name'] as $_FILES['image']['name'])
{
//print_r($_FILES['image']['name']);
try
{ echo "1";
$uploader = new Varien_File_Uploader('image'); echo "hi";
//print_r($uploader);exit;
$uploader->setAllowedExtensions(array('jpg','jpeg','gif','png','flv'));
$uploader->setAllowRenameFiles(false);
$uploader->setFilesDispersion(false);
$uploader->setAllowCreateFolders(true);
// Set media as the upload dir
$media_path = Mage::getBaseDir('media') . DS . 'blog' . DS;
$imgFilename = time() . $postData['image'];
// Upload the image
//$uploader->save($media_path, $_FILES['image']['name']);echo "4";
$uploader->save($media_path, $imgFilename);
}
catch (Exception $e)
{
Mage::log($e);
$this->_redirectError(502);
}
$data['image'] = $imgFilename;
}
}
else
{
if(isset($data['image']['delete']) && $data['image']['delete'] == 1)
$data['image'] = '';
else
unset($data['image']);
}
//echo "out"; exit;
if( $this->getRequest()->getParam('id') <= 0 )
$articleModel->setCreatedTime(
Mage::getSingleton('core/date')
->gmtDate());
$articleModel
->addData($postData)
->setUpdatedTime(
Mage::getSingleton('core/date')
->gmtDate())
->setId($this->getRequest()->getParam('id'))
->save();
$lastid = $articleModel->getId();
if($data['image'] != '')
{
foreach($data['image'] as $img)
{
$imageModel=Mage::getModel('blog/image');
$imageModel->setArticleId($lastid)->setImage($data['image'])->save();
}
}
Mage::getSingleton('adminhtml/session')
->addSuccess('successfully saved');
Mage::getSingleton('adminhtml/session')
->setarticleData(false);
$this->_redirect('*/*/');
//return;
if ($this->getRequest()->getParam('back'))
{
$this->_redirect('*/*/edit',array('id' => $articleModel->getId()));
return;
}
}
catch (Exception $e)
{
Mage::getSingleton('adminhtml/session')
->addError($e->getMessage());
Mage::getSingleton('adminhtml/session')
->setarticleData($this->getRequest()
->getPost());
$this->_redirect('*/*/edit',
array('id' => $this->getRequest()
->getParam('id')));
return;
}
}
$this->_redirect('*/*/');
}
and here is my form for the image
<?php
class Vertax_Blog_Block_Adminhtml_Article_Edit_Tab_Image extends Mage_Adminhtml_Block_Widget_Form
{
protected function _prepareForm()
{
$form = new Varien_Data_Form();
$this->setForm($form);
$fieldset = $form->addFieldset('image_form',
array('legend'=>'image'));
//$fieldset->addType('image', Mage::getConfig()->getBlockClassName('blog/adminhtml_article_helper_image'));
$fieldset->addType('image', 'Vertax_Blog_Block_Adminhtml_Article_Helper_Image');
$fieldset->addField('image', 'image', array(
'label' => 'Image',
'required' => false,
'name' => 'image[]',
'multiple' => 'multiple',
'mulitple' => true,
));
if (Mage::getSingleton('adminhtml/session')->getBlogPostData()) {
$form->setValues(Mage::getSingleton('adminhtml/session')->getBlogPostData());
Mage::getSingleton('adminhtml/session')->setBlogPostData(null);
} elseif (Mage::registry('article_data')) {
$form->setValues(Mage::registry('article_data')->getData());
}
return parent::_prepareForm();
}
}
?>

Answer 1

$uploader = new Mage_Core_Model_File_Uploader(
array(
'name' => $_FILES['galleryImage']['name'][$i],
'type' => $_FILES['galleryImage']['type'][$i],
'tmp_name' => $_FILES['galleryImage']['tmp_name'][$i],
'error' => $_FILES['galleryImage']['error'][$i],
'size' => $_FILES['galleryImage']['size'][$i]
));

Answer 2

Waseem,please try code for upload image..
$uploader = new Mage_Core_Model_File_Uploader('image');
$uploader->setAllowedExtensions(array('jpg', 'jpeg', 'gif', 'png'));
$uploader->setFilesDispersion(true);
$media_path = Mage::getBaseDir('media') . DS . 'blog' . DS;
$imgFilename = time() . $postData['image'];
// Upload the image
//$uploader->save($media_path, $_FILES['image']['name']);echo "4";
$uploader->save($media_path, $imgFilename);

Answer 3

there was a problem in your code while adding fieldset
$fieldset->addField('image', 'image', array(
'label' => 'Image',
'required' => false,
'name' => 'image[]',
'multiple' => 'multiple',
'mulitple' => true,
));
here you had set the name to image[] which in turn will return the array as $_FILES['image][name][], $_FILES['image][tmp_name][].
If you want to upload single file then set 'name' = 'image' or see this question

Answer 4

Try to use
$uploader = new Varien_File_Uploader($_FILES['image']);
instead of what you use currently.
