README
A front-end control for sorting SilverStripe lists easily. The aim of this module is to make sorting lists as simple as it is to use PaginatedList.
Requirements
- SilverStripe 4+ or 5+
Usage
There are a few ways you can define sort options within an array.
Make a public function on your controller:
public function getSorter(){ $sorts = [ 'Title', //DB field name only 'Popularity' => 'Popularity DESC', //map title to sort sql 'Price' => ['BasePrice' => 'ASC'], //map title to data list sort ListSorter_Option::create('Age', ['Created' => 'DESC'], //object ListSorter_Option::create('Age', ['Created' => 'ASC']) //reverse ) ; return ListSorter::create($this->request,$sorts); }
Call that function when updating your list:
public function getSortableChildren() { $list = $this->Children(); $list = $this->getSorter()->sortList($list); return $list; }
Use my template or roll your own.
<% include Sorter %>
<ul>
<% loop SortableChildren %>
<li>$Title</li>
<% end_loop %>
</ul>
Usage with Silvershop
Silvershop's PageCategoryController comes with some sortings predefined. If you want to define your own sorting possibilities, you can add an Extension to ProductCategory like this:
<?php namespace MyNamespace\SilverShop\Extensions; use SilverShop\ListSorter\ListSorter; use SilverShop\ListSorter\ListSorterOption; use SilverStripe\Core\Extension; use SilverStripe\Security\Security; class ProductCategorySorting extends Extension { public function updateSorter(ListSorter $sorter) { $basePriceOptionDESC = ListSorterOption::create('BasePrice highest first', ['BasePrice' => 'DESC']); $basePriceOptionASC = ListSorterOption::create('BasePrice lowest first', ['BasePrice' => 'ASC']); $titleOptionASC = ListSorterOption::create('Title a-z', ['Title' => 'ASC']); $titleOptionDESC = ListSorterOption::create('Title z-a', ['Title' => 'DESC']); $newestOption = ListSorterOption::create('Newest first', ['Created' => 'DESC']); $popularityOption = ListSorterOption::create('Most Popular', ['Popularity' => 'DESC']); //overwrite all settings //you can use $sorter->addSortOption($option) if you want to add a sort option $sorter->setSortOptions([ $basePriceOptionASC, $basePriceOptionDESC, $titleOptionASC, $titleOptionDESC, $newestOption, $popularityOption ]); } }
Then add this extension to ProductCategoryController in your config:
SilverShop\Page\ProductCategoryController: extensions: - MyNamespace\Silvershop\Extensions\ProductCategorySorting
