Complex Category

Category that allows sorting of products and selecting pagination length

Installation

Install this module using composer

composer require silvercommerce/complex-category

Usage

This module adds a new category type called "Complex Category" that you can add
via the admin interface. These categories allow you to add a SortLimitForm
that will add "sort" and "show" dropdowns and automatically update the product list.

Add Form to Template

This module requires you to add a $SortLimitForm variable to your category templates.

You can add this to all category templates, or specify a specific template for your
complex category.

Customising sort and page length options

You can add custom sort and page length options via SilverStripe config. The config options
are as follows.

ComplexCategoryController.sort_options

An array of sort options, where the key is the sort (which is loaded into the DataList::sort()
call) and the value is what is loaded in the dropdown.

If you wanted to add a "Date Added" field to the sort, you could add the following to your config.yml

ComplexCategoryController:
  sort_options:
    "Created ASC": "Added (most recent first)"
    "Created DESC": "Added (oldest first)"

ComplexCategoryController.show_options

An array of page length options, where the key is the length (used by PaginatedList::setPageLength())and the value is what is loaded in the dropdown.

If you wanted to add 120 and 150 to the field, you could add the following to your config.yml

ComplexCategoryController:
  show_options:
    "120": "120"
    "150": "150"

NOTE: To attempt to help protect against attacks such as SQL injection, none of the above pass
queries are passed via the URL, instead a index of the selected option is passed and then the
controller selects the appropriate setting.
