This package allows you to define flexible pricing rules based on various conditions and apply actions like discounts or markups. Installation ------------ [](#installation) You can install the package via composer: ``` composer require php-junior/pricing-engine ``` You can publish the config file with: ``` php artisan vendor:publish --provider="PhpJunior\PricingEngine\Providers\PricingEngineServiceProvider" ``` You can run the migrations with: ``` php artisan migrate ``` Configuration ------------- [](#configuration) The configuration file `config/pricing-engine.php` allows you to customize: - Model classes - Table names - Priority order (highest first or lowest first) - Save Usage Records - Available operators - Available actions Usage ----- [](#usage) ### Creating Pricing Rules [](#creating-pricing-rules) You can create pricing rules using the `PricingEngine` facade or service. ``` use PhpJunior\PricingEngine\Facades\PricingEngine; use PhpJunior\PricingEngine\Data\ConditionData; use PhpJunior\PricingEngine\Data\ActionData; PricingEngine::make()->savePricingRule( name: 'VIP Discount', priority: 1, conditions: [ new ConditionData( attribute: 'customer_group', operator: '=', value: 'vip' ), new ConditionData( attribute: 'price_total', operator: '>', value: '100' ) ], actions: [ new ActionData( type: 'percentage_discount', value: 10 ) ] ); ``` Attributes in conditions can be any key. To update an existing rule, provide the rulr ID in them `make` method: ``` PricingEngine::make(id: 1)->savePricingRule( ... ); ``` To delete a rule, use the `deletePricingRule` method: ``` PricingEngine::make(id: 1)->deletePricingRule(); ``` Fetch all pricing rules: ``` $rules = PricingEngine::make()->getAllPricingRules(); ``` ### Calculating Price [](#calculating-price) To calculate the price based on the defined rules, use the `calculatePrice` method. You need to provide the base price and a context array containing attributes used in your conditions. ``` use PhpJunior\PricingEngine\Facades\PricingEngine; $result = PricingEngine::calculatePrice( basePrice: 200, context: [ 'customer_group' => 'vip', 'price_total' => 200 ] ); // $result will contain: // [ // 'original_price' => 200, // 'final_price' => 180, // 'applied_rules' => [ ... ] // ] ``` Location-based pricing example: ``` use PhpJunior\PricingEngine\Facades\PricingEngine; use PhpJunior\PricingEngine\Data\ConditionData; use PhpJunior\PricingEngine\Data\ActionData; PricingEngine::make()->savePricingRule( name: 'Location Based Discount', priority: 1, conditions: [ new ConditionData( attribute: 'location', operator: 'location_in', value: ['US', 'CA'] ) ], actions: [ new ActionData( type: 'fixed_discount', value: 20 ) ] ); $result = PricingEngine::calculatePrice( basePrice: 150, context: [ 'location' => 'ip_address_here' ] ); // $result will contain: // [ // 'original_price' => 150, // 'final_price' => 130, // 'applied_rules' => [ ... ] // ] ``` for location-based conditions, used this package `stevebauman/location` to resolve IP addresses to locations. get more info [here](https://github.com/stevebauman/location) ### Available Operators [](#available-operators) - `=` - `!=` - `>` - `>=` - ` [ 'custom_operator' => App\Operators\CustomOperator::class, ], 'actions' => [ 'custom_action' => App\Actions\CustomAction::class, ], ``` Then you can use them in your pricing rules. ``` use PhpJunior\PricingEngine\Facades\PricingEngine; use PhpJunior\PricingEngine\Data\ConditionData; use PhpJunior\PricingEngine\Data\ActionData; PricingEngine::make()->savePricingRule( name: 'Custom Rule', priority: 2, conditions: [ new ConditionData( attribute: 'custom_attribute', operator: 'custom_operator', value: 'some_value' ) ], actions: [ new ActionData( type: 'custom_action', value: 15 ) ] ); ``` Testing ------- [](#testing) ``` composer test ``` Credit ------ [](#credit) - [Steve Bauman](https://github.com/stevebauman) for his location package which is used for location-based pricing rules.
