Download all files with Views 2

In case someone still need this, here is my solution, it's not pretty, but it works.
I had to do some custom scripting. I created this js function in my theme script.js

function downloadSelected()
{
	var documents=Array();
	var v=0;
	$(".view-Document-list form").each(function () {
		if ($(this).find(".form-checkbox").attr('checked'))
		{
			var val = $(this).find("input[name='document_url']").val();
			documents[v] = val;
		}
		v++;
	});
	$.ajax({
		url: "/sites/all/themes/apetrovic/ajax-request.php?documents="+documents,
		success: function (data)
		{
			window.location = data;
		}
	});
}

.view-Document-list you have to replace with you own class (depending on view name), and "sites/all/themes/apetrovic/ajax-request.php" is a path to custom script where you process selected files to zip and force download:

//function to zip and force download the files using PHP
function zipFilesAndDownload($file_names,$archive_file_name,$file_path)
{
	$zip = new ZipArchive();
	//create the file and throw the error if unsuccessful
	if ($zip->open($file_path."sites/default/files/".$archive_file_name, ZIPARCHIVE::CREATE )!==TRUE) {
    	exit("cannot open <$archive_file_name>\n");
	}
	//add each files of $file_name array to archive
	foreach($file_names as $files)
	{
  		if(!empty($files))
		{			
			$file=str_replace("sites/default/files/","",$files);
			
			$zip->addFile($file_path.$files,$file);
		}
	}
	$zip->close();
	echo "sites/default/files/".$archive_file_name;
}



if($_GET['documents'])
{
	$documents=explode(",",$_GET['documents']);
	
	$file_names=$documents;
	$archive_file_name='zipped-'.time().'.zip';
	$file_path=$_SERVER['DOCUMENT_ROOT'].'/';
	zipFilesAndDownload($file_names,$archive_file_name,$file_path);
}

So now all you have to do is to add a link, that will call js function. I put it in my view footer like this:

<a href="javascript:downloadSelected()">Download selected</a>
