Create Dynamic Discounts with Custom Conditions on Laravel With the Discountify Package image

Discountify is a Laravel package designed for managing dynamic discounts with custom conditions. You can use this package to create flexible conditions around discounts using the following Condition class:

use Safemood\Discountify\Facades\Condition;
 
// If items are more than 2, apply a 10% discount.
Condition::define('more_than_2_products_10', fn (array $items) => count($items) > 2, 10)
// ...
->defineIf('client_has_renewal_10', auth()->user()->hasRenewal(), 10);

The documentation has more examples of complex conditions around dates or special items that can apply even more discounts.

Once you create conditions, you can then pass items of data to them, set global discounts, taxes, etc., and get the total back:

// Set the items in the cart
Discountify::setItems($items)
->setGlobalDiscount(15) // Set a global discount for all items
->setGlobalTaxRate(19); // Set a global tax rate for all items
 
// Calculate the total amount considering the set conditions and discounts
$total = Discountify::total();
 
// Calculate the total amount with the applied global discount
$totalWithDiscount = Discountify::totalWithDiscount();

This package is relatively new, but I like the idea of a package that can take in an array or model of products and conditionally apply discounts. At the time of writing (v1.2.0), it supports the following features:

  • Set global discount and tax rates
  • Calculate total amounts with discount, including tax
  • Dynamic field names through configuration or on the fly
  • Class-based discount conditions based on any custom logic you want
  • Ability to skip discounts
