SilverStripe Sortable Upload Field Module

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');
