Installation Instructions

Composer

Run the following to add this module as a requirement and install it via composer.

composer require "webfox/silverstripe-dropzone-sortable"

Setup

Setting up the Relation

We need a SortOrder column on the Image/File relation that FileAttachmentField is hooked onto.
For a has_many to a custom DataObject simply add the 'SortOrder' => 'int' and private static $default_sort = 'SortOrder'; to the DataObject.

If you are relating to Image or File directly then you will need a many_many setup with many_many_extrafields and an accessor to loop over in the template
<% loop $SortedImages>...<% end_loop %> or you can do <% loop $Images.Sort('SortOrder') %>...<% end_loop %>. This package will automatically sort the files in the FileAttachmentField.

Here is an example many_many setup:

class MyPage extends Page {
    
    private static $many_many = [
        'Images' => 'Image'
    ];

    private static $many_many_extraFields = [
        'Images' => ['SortOrder' => 'Int']
    ];
    
    public function getSortedImages(){
        return $this->Images()->sort('SortOrder');
    }
}

Enabling Sorting

To enable sorting simply call ->sortable() on the FileAttachmentField e.g. FileAttachmentField::create('Images')->sortable()->imagesOnly();

Customization

The only customization available is changing the sort column. FileAttachmentField::create('Images')->sortable()->setSortableColumn('OtherSortColumn');
