Magento ECG discourage $_FILES superglobal

Question

I'm using the magento ECG coding standards on a project and am getting the following:

ERROR | Direct use of $_FILES Superglobal detected.

I've grepped through the code and can see that core uses the $_FILES superglobal, does magento have a wrapper function for this or should i ignore the error?

Answer 1

use below in place of $_FILES

try {
    $uploader = Mage::getModel('core/file_uploader', 'field_name');
    $uploader->setAllowedExtensions(array('jpg', 'jpeg', 'gif'));
    $result = $uploader->save($path); 
} catch (Exception $e) {
    echo $e->getMessage();
}

To know more what possibly can be done with this approach, go to /app/code/core/Mage/Adminhtml/controllers/Catalog/Product/GalleryController.php

Hope it helps.
