Example usage

This module was not hooked up with any particular module that adds products to allow flexibility. The examples here will use FoxyStripe.

ProductWishList Extension

A product relation must be added to Dynamic\Wishlist\Model\ProductWishList through a DataExtension.

Dynamic\Wishlist\Model\ProductWishList:
  extensions:
    - Foo\Bar\ORM\WishListExtension

<?php

namespace Foo\Bar\ORM;

use Dynamic\FoxyStripe\Page\ProductPage;
use SilverStripe\ORM\DataExtension;

class WishListExtension extends DataExtension
{
    /**
     * @var array
     */
    private static $many_many = [
        'Products' => ProductPage::class,
    ];
}

Product Relation

The Product must also have a reciprocal relation to wishlists.

Dynamic\FoxyStripe\Page\ProductPage:
  extensions:
    - Foo\Bar\ORM\ProductExtension

<?php

namespace Foo\Bar\ORM;

use Dynamic\Wishlist\Model\ProductWishList;

class ProductExtension extends DataExtension
{
    /**
     * @var array
     */
    private static $belongs_many_many = [
        'WishLists' => ProductWishList::class,
    ];
}

WishList Form

The ProductControllerExtension should be applied to the controller that handles showing a product.

Dynamic\FoxyStripe\Page\ProductPageController:
  extensions:
    - Dynamic\Wishlist\Extensions\ProductControllerExtension

The form can be passed a product id to avoid using the current controller's page id. The form will not show if the user is not logged in.

AddToWishListForm and RemoveFromWishListForm

The only real difference between these forms are the actions the forms call and an extra class.

updateWishLists

An extension point for updating the wishlists visible in the dropdown field. It is passed a DataList of the wishlists associated with the current user.

/**
 * @param SilverStripe\ORM\DataList $lists
 */
public function updateWishLists($lists)
{
    // Stuff here
}

updateFields

An extension point for updating the fields for the form. It is passed a FieldList and an int.

/**
 * @param SilverStripe\Forms\FieldList $fields
 * @param int $productID
 */
public function updateFields($fields, $productID)
{
    // Stuff here
}

updateActions

An extension point for updating the actions for the form. It is passed a FieldList and an int.

/**
 * @param SilverStripe\Forms\FieldList $actions
 * @param int $productID
 */
public function updateActions($actions, $productID)
{
    // Stuff here
}

WishList Form Handling

Handling the addToWishList and removeFromWishList actions is not included by default. The example implementations should be on a controller, or an extension applied to a controller.

addToWishList Example

/**
 * @param $data
 * @param \SilverStripe\Forms\Form $form
 * @return \SilverStripe\Control\HTTPResponse
 * @throws \Exception
 */
public function addToWishList($data, Form $form)
{
    /** @var ProductWishList|\Foo\Bar\Extension\WishListExtension $list */
    $list = ProductWishList::get()->filter([
        'ID' => $data['List'],
    ])->first();

    $list->Products()->add($data['ProductID']);

    return $this->owner->redirectBack();
}

removeFromWishList Example

/**
 * @param $data
 * @param \SilverStripe\Forms\Form $form
 * @return \SilverStripe\Control\HTTPResponse
 * @throws \Exception
 */
public function removeFromWishList($data, Form $form)
{
    /** @var ProductWishList|\Foo\Bar\Extension\WishListExtension $list */
    $list = ProductWishList::get()->filter([
        'ID' => $data['List'],
    ])->first();

    $list->Products()->removeByID($data['ProductID']);

    return $this->owner->redirectBack();
}
