I am new to silverstripe. I am trying to create a customized multiple image upload field for a specific page type following Silverstripe documentation ( I am using latest Siverstripe framework & cms . Now while running mysite/?flush its showing "Fatal error: Access level to ProductPageFile::$many_many must be public (as in class Page).... ".

This is my page code:


class ProductPageFile extends Page {
private static $many_many = array('GalleryImages' => 'Image');

function getCMSFields() {

$fields = parent::getCMSFields();

$uploadField = new UploadField(
$name = 'GalleryImages',
$title = 'Upload one or more images (max 10 in total)'

return $fields;

class ProductPageFile_Controller extends Page_Controller {
function NewPublicUploads($FolderName) {
$FolderName = str_replace(" ","-",$FolderName);
return DataObject::get(
$name = 'File',
$filter = "ClassName = 'Image' and Filename like 'assets/".$FolderName."/%'",
$sort = "Created DESC",
$join = "",
$limit = ""

class GalleryImageExtension extends DataExtension {
private static $belongs_many_many = array('Galleries' => 'ProductPageFile');


can you please guide me to build a custom multiple image upload field for specific page type.

Thank you.

It sounds like you're following the documentation for 3.1 when you're using 3.0.x. This is the documentation you should be using:

Change your private static $many_many to be public static $many_many, and do the same for your private static $belongs_many_many - should be public static $belongs_many_many.

Apart from that, your code looks (at a glance) like it should work.
