Image doesn't upload in custom module magento

Question

I have created custom module in magento with image upload attribute. Image name was successfully stored in DB table. But image doesn't upload to the target folder.

I have tried with this following code. please show me "what am i doing wrong here"

 $uploader = new Varien_File_Uploader('fileinputname');
 $uploader->setAllowedExtensions(array('jpg','jpeg','gif','png'));
 $uploader->setAllowRenameFiles(false);
 $uploader->setFilesDispersion(false);
 $path = Mage::getBaseDir('media') .DS. 'foo'.DS ;
 $uploader->save($path, $_FILES['fileinputname']['name']);

• Magento Learner: Check if target folder has write permissions
• Shathish: i think you verified magentocommerce.com/wiki/5_-_modules_and_development/admin/…, for this, first check print_r($_FILES);exit; before the if condition if(isset($_FILES['fileinputname']['name']) and (file_exists($_FILES['fileinputname']['tmp_name']))) {, you'll find the key you used is wrong.

Answer 1

I just edit file path like

 $path = Mage::getBaseDir('media').'/foo/';

instead of

$path = Mage::getBaseDir('media') .DS. 'foo'.DS ;

That's All. Now Its working well

Try Below code,Below code works for me and just I give permission to directory where image will be stored

$uploader = new Varien_File_Uploader('fileinputname');
 $uploader->setAllowedExtensions(array('jpg','jpeg','gif','png'));
 $uploader->setAllowRenameFiles(false);
 $uploader->setFilesDispersion(false);
 $path = Mage::getBaseDir('media') .DS. 'foo'.DS ;
 if(!is_dir($path))
 mkdir($path, 0777, true);
 $uploader->save($path, $_FILES['fileinputname']['name']);
