How To Upload Images and Show Their Thumbnails From Custom Module Admin Form

Question

I have a custom grid. Need to upload product images from admin form of the custom module.

Here is the grid Edit file at:

app\code\local\Crud\Banner\Block\Adminhtml\Banner\Edit\Form.php

 $fieldset = $form->addFieldset('banner_form', array('legend'=>Mage::helper('banner')->__('Banner information')));
 $fieldset->addField('title', 'text', array(
 'label' => Mage::helper('banner')->__('Title'),
 'class' => 'required-entry',
 //'required' => true,
 //'readonly' => true,
 'name' => 'title',
 ));
 $fieldset->addField('filename', 'image', array(
 'label' => Mage::helper('banner')->__('Upload Banner'),
 'class' => 'required-entry',
 //'required' => true,
 //'readonly' => true,
 //'renderer' => 'banner/adminhtml_banner_renderer_image',
 'name' => 'filename',
 ));
 $fieldset->addField('status', 'select', array(
 'label' => Mage::helper('banner')->__('Status'),
 'name' => 'status',
 'values' => array(
 array(
 'value' => 1,
 'label' => Mage::helper('banner')->__('Desabilitado'),
 ),
 array(
 'value' => 0,
 'label' => Mage::helper('banner')->__('Habilitado'),
 ),
 ),
 ));
 if ( Mage::getSingleton('adminhtml/session')->getBannerData() )
 {
 $form->setValues(Mage::getSingleton('adminhtml/session')->getBannerData());
 Mage::getSingleton('adminhtml/session')->setBannerData(null);
 } elseif ( Mage::registry('banner_data') ) {
 $form->setValues(Mage::registry('banner_data')->getData());
 }
 $this->setForm($form);
 return parent::_prepareForm();
}

Here is the controller SaveAction:

public function saveAction()
{
 if ( $this->getRequest()->getPost() ) {
 try {
 $postData = $this->getRequest()->getPost();
 $bannerModel = Mage::getModel('banner/banner');
 $bannerModel->setId($this->getRequest()->getParam('id'))
 ->setTitle($postData['title'])
 ->setStatus($postData['status'])
 ->save();
 Mage::getSingleton('adminhtml/session')->addSuccess(Mage::helper('adminhtml')->__('Data was successfully saved'));
 Mage::getSingleton('adminhtml/session')->setBannerData(false);
 $this->_redirect('*/*/');
 return;
 } catch (Exception $e) {
 Mage::getSingleton('adminhtml/session')->addError($e->getMessage());
 Mage::getSingleton('adminhtml/session')->setBannerData($this->getRequest()->getPost());
 $this->_redirect('*/*/edit', array('id' => $this->getRequest()->getParam('id')));
 return;
 }
 }
 $this->_redirect('*/*/');
}

I have updated the save controller with image save code, Check the below code

public function saveAction()
{
 if ( $this->getRequest()->getPost() ) {
 try {
 $postData = $this->getRequest()->getPost();
 $bannerModel = Mage::getModel('banner/banner');
 if(isset($_FILES['filename']['name])) {
 try {
 $uploader = new Varien_File_Uploader('filename');
 $uploader->setAllowedExtensions(array('jpg','jpeg','gif','png')); // or pdf or anything
 $uploader->setAllowRenameFiles(false);
 $uploader->setFilesDispersion(false);
 $path = Mage::getBaseDir('media') . / ;
 $uploader->save($path, $_FILES['filename']['name']);
 $postData['filename'] = $path.$_FILES['filename']['name'];
 }catch(Exception $e) {
 Mage::getSingleton('adminhtml/session')->addError($e->getMessage());
 }
 }
 $bannerModel->setId($this->getRequest()->getParam('id'))
 ->setTitle($postData['title'])
 ->setStatus($postData['status'])
 ->setStatus($postData['filename'])
 ->save();
 Mage::getSingleton('adminhtml/session')->addSuccess(Mage::helper('adminhtml')->__('Data was successfully saved'));
 Mage::getSingleton('adminhtml/session')->setBannerData(false);
 $this->_redirect('*/*/');
 return;
 } catch (Exception $e) {
 Mage::getSingleton('adminhtml/session')->addError($e->getMessage());
 Mage::getSingleton('adminhtml/session')->setBannerData($this->getRequest()->getPost());
 $this->_redirect('*/*/edit', array('id' => $this->getRequest()->getParam('id')));
 return;
 }
 }
 $this->_redirect('*/*/');
}

Hope it will work for you.
