uploading & working with Multiple files on POST (view function in page type controller)

Permalink
Trying to work with multiple files selected on a front end form, using my own theme, which is using the view function in a page type controller of a page using this:
$images = $_POST['images[]'];


The input field on my page looks like this:
<input type="file" multiple value="" name="images[]" id="images" />


Currently returns NULL on submit, what am I doing wrong??

I am aware I can get a single file in like this:
Loader::library("file/importer");
$fi = new FileImporter(); 
$newFile = $fi->import($pathToFile, $nameOfFile, $fileObject);


I presume a foreach on the multiple files array would be ok, though how would I add to a set?
