=====Files Handler=====

>>==See also:==
Documentation: FilesHandlerInfo.>>This is the development page for the Files handler.::c::

This is another a complete refactoring of the FilesManagementHandler I proposed previously. The new overview can be found at FilesManagementSolution

===Dependancy===
None.

===The code===
//to be saved as files.php in the handlers/page directory.// 

%%(php;1)
<div class="page"> 
<?php
if (! function_exists('mkdir_r')) {
		function mkdir_r ($dir) {
				if (strlen($dir) == 0) return 0;
				if (is_dir($dir)) return 1;
				elseif (dirname($dir) == $dir) return 1;
				return (mkdir_r(dirname($dir)) and mkdir($dir,0755));
		}
}

if ($download <> '') {
		// link to download a file
		if ($text == '') $text = $download;
		echo "<a href=\"".$this->href('files.xml',$this->GetPageTag(),'action=download&file='.urlencode($download))."\">".$text."</a>";

} elseif ($this->page AND ($this->method <> 'print.xml') AND ($this->method <> 'edit')) {

		// upload path
		if ($this->config['upload_path'] == '') $this->config['upload_path'] = 'files';
		$upload_path = $this->config['upload_path'].'/'.$this->GetPageTag();
		if (! is_dir($upload_path)) mkdir_r($upload_path);

		// upload action
		$uploaded = $_FILES['file'];
