Magento sort media folder files by filename - sorting

Question

I want to sort media folder files by filename.I tried with
$collection = $this->getCollection($path)
->setCollectDirs(false)
->setCollectFiles(true)
->setCollectRecursively(false)
->setOrder('filename', Varien_Data_Collection::SORT_ORDER_ASC);
but it is not case sensitive.It sorts all upper case words first then lowercase. (Apple,Bat,apple)
Please help !!!

Answer 1

You have to rewrite lib/Varien/Data/Collection/Filesystem.php
and change function
protected function _usort($a, $b)
{
foreach ($this->_orders as $key => $direction) {
$result = $a[$key] > $b[$key] ? 1 : ($a[$key] < $b[$key] ? -1 : 0);
return (self::SORT_ORDER_ASC === strtoupper($direction) ? $result : -$result);
break;
}
}

Answer 2

Please try this:
- create a test.php file in magento root directory.
- change the name of media folder to $sub_dir variable.
<?php
require_once 'app/Mage.php';
Mage::app();
$file = new Varien_Io_File();
$sub_dir = "wysiwyg/new";
$dir = Mage::getBaseDir('media') . DS . $sub_dir . DS;
$file->open(array('path' => $dir));
$fileDetails = $file->ls();
$allFiles = array();
foreach ($fileDetails as $value) {
$allFiles[] = $value['text'];
}
echo "<pre>";
print_r($allFiles);
echo "</pre>";
?>
