Usage

<?php

use gorriecoe\Link\Models\Link;
use gorriecoe\LinkField\LinkField;

class MyClass extends DataObject
{
    private static $has_one = [
        'Button' => Link::class
    ];

    private static $many_many = [
        'Buttons' => Link::class
    ];

    private static $many_many_extraFields = [
        'Buttons' => [
            'Sort' => 'Int' // Required for all many_many relationships
        ]
    ];

    /**
     * CMS Fields
     * @return FieldList
     */
    public function getCMSFields()
    {
        $fields = parent::getCMSFields();
        $fields->addFieldsToTab(
            'Root.Main',
            [
                LinkField::create(
                    'Button',
                    'Button',
                    $this
                ),
                LinkField::create(
                    'Buttons',
                    'Buttons',
                    $this
                )
            ]
        );
        return $fields;
    }
}

Sort column

By default the LinkField assumes that the sort column is named Sort. If you want to use another field name such as SortOrder, you can specify it using the setSortColumn method like so:

LinkField::create(
    'Buttons',
    'Buttons',
    $this
)->setSortColumn('SortOrder')

You can also globally define the sort column. In your config.yml add the following:

gorriecoe\LinkField\LinkField:
  sort_column: 'SortOrder'

Belongs many many

We can also add a belongs_many_many relation to the Link class. In your config.yml add the following:

gorriecoe\Link\Models\Link:
  belongs_many_many:
    MyCustomObject : MyCustomObject.Buttons
