DigressivePrice

Easily create and manage range of quantities with associated discounts.

Installation

Warning : to get real time changes of digressive prices on the product page, you have to use Thelia 2.4, or replace in thelia.js :

$pse.id.val(pseId);

with

$pse.id.val(pseId).trigger('change.pse', pseId);

Manually

Copy the module into <thelia_root>/local/modules/ directory and be sure that the name of the module is DigressivePrice.
Activate it in your thelia administration panel

Composer

Add it in your main thelia composer.json file

composer require thelia/digressiveprice-module:~1.0

Usage

Once activated, go into the Digressive Prices tab of the product you want to add a digressive price to. You can create a new range, edit or remove an existing one. Fill the form with following information :

Quantity
- from : the quantity which begins your range
- to : the quantity that ends you range.
Discount in %

Then click the "Add" or "Update" button.

Take care of the following :

"quantity to" has to be greater than or equal to "quantity from"
a quantity ('from' and/or 'to') can't be included into another range
a range can't surround another one
a quantity can't be negative

Once created, a table of digressive price is displayed on the product page. This table is updated when the PSE is changed.

The price will be automatically updated according to the product's quantity in the user's cart.

This module is only hooked into the Modules tab of the products. The Hook used is called "product.tab-content".

On the front-offcie, the module uses the product.details-bottom and product.javascript-initialization hooks.
