Magento custom image upload doesn't work - magento

Question

I need to create an image upload field for posts in Magento Blog Module (AW blog).
Therefore, each post needs to contain an image.
I edited the following files:
/home/clients/websites/w_gale/public_html/gale/app/code/community/AW/Blog/Block/Manage/Blog/Edit/Tab/Form.php
added fieldset like this:
$fieldset->addField('fileinputname', 'image', array(
'label' => Mage::helper('blog')->__('Upload image'),
'required' => false,
'name' => 'fileinputname',
'required' => true,
'style' => 'height:100px;border:2px solid #999;',
));
on top of this file, in the right place, I defined form like this:
$form = new Varien_Data_Form(array(
'id' => 'edit_form',
'action' => $this->getUrl('*/*/save', array('id' => $this->getRequest()->getParam('id'))),
'method' => 'post',
'enctype' => 'multipart/form-data',
)
);
In Blogcontroller.php I added the following code, just bellow the if ($data = $this->getRequest()->getPost()) { line
if(isset($_FILES['fileinputname']['name']) && (file_exists($_FILES['fileinputname']['tmp_name']))) {
try {
$uploader = new Varien_File_Uploader('fileinputname');
$uploader->setAllowedExtensions(array('jpg','jpeg','gif','png')); // or pdf or anything
$uploader->setAllowRenameFiles(true);
$uploader->setFilesDispersion(false);
$path = Mage::getBaseDir('media') . DS ;
$uploader->save($path, $_FILES['fileinputname']['name']);
$data['imageurl'] = $_FILES['fileinputname']['name'];
} catch(Exception $e) {
}
} else {
if(isset($data['fileinputname']['delete']) && $data['fileinputname']['delete'] == 1)
$data['imageurl'] = '';
else
unset($data['fileinputname']);
}
However, the upload doesn't work. What am I doing wrong?
I added a special row in appropriate field in a database.
The frontend section displays the database value when I enter it manually.
Thanks

This code of method from data helper which uploads image. You need implement method getBaseDir() (which returns dir where you wish store your uploaded files) by yourself.
/**
* Upload image and return uploaded image file name or false
*
* #throws Mage_Core_Exception
* #param string $scope the request key for file
* #return bool|string
*/
public function uploadImage($scope)
{
$adapter = new Zend_File_Transfer_Adapter_Http();
$adapter->addValidator('ImageSize', true, $this->_imageSize);
$adapter->addValidator('Size', true, $this->_maxFileSize);
if ($adapter->isUploaded($scope)) {
// validate image
if (!$adapter->isValid($scope)) {
Mage::throwException(Mage::helper('mycompany_mymodule')->__('Uploaded image is not valid'));
}
$upload = new Varien_File_Uploader($scope);
$upload->setAllowCreateFolders(true);
$upload->setAllowedExtensions(array('jpg', 'gif', 'png'));
$upload->setAllowRenameFiles(true);
$upload->setFilesDispersion(false);
if ($upload->save($this->getBaseDir())) {
return $upload->getUploadedFileName();
}
}
return false;
}

You're using the right code. I solved the problem by using the right MYSQL data type. When I changed the data type from 'text' to 'varchar(255)' it solved the problem
And ... make sure that you add the following code:
$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',
)
);
in /app/code/community/AW/Blog/Block/Manage/Blog/Edit/Form.php
NOT: app/code/community/AW/Blog/Block/Manage/Blog/Edit/Tab/Form.php
