README

This module creates a subclass of UploadField that allows for sorting the managed files.

Also changes the upload interface which is heavily inspired by the more complete but use-specific Gallery module (https://github.com/frankmullenger/silverstripe-gallery).

Still in development.

Usage

By default the field will use the File's Sort attribute for sorting. You'll need to make a subclass of File or Image to give it a sort field and $default_sort:

class SlideshowImage extends Image {
	static $default_sort = 'Sort ASC';

	static $db = array(
		'Sort' => 'Int'
	);
	static $has_one = array(
		'Page' => 'Page'
	);
}

And in the page:

	...

	private static $has_many = array(
		'Slides' => 'SlideshowImage'
	);

	public function getCMSFields() {
		$fields = parent::getCMSFields();

		$fields->addFieldToTab('Root.Slides', $field = SortableUploadField::create('Slides', 'Slides'));

		return $fields;
	}

	...

This will produce

You can change the name of the sort attribute with $sortableField->setSortField('SortOrderOrWhatever');
