A flexible condition evaluation system for Symfony applications, providing a framework for defining, managing, and evaluating various types of conditions.

Features

• Flexible Condition System: Create and manage various types of conditions with custom handlers
• Evaluation Engine: Evaluate conditions against specific contexts and actors
• Extensible Architecture: Easy to add new condition types by implementing handlers
• Trigger Support: Built-in support for different condition triggers
• Validation: Comprehensive configuration validation for conditions
• Batch Evaluation: Evaluate multiple conditions at once

Installation

You can install this bundle via Composer:

composer require tourze/condition-system-bundle

Requirements

• PHP 8.1 or higher
• Symfony 6.4 or higher
• Doctrine ORM 3.0 or higher

Quick Start

1. Register the bundle in your config/bundles.php:

return [
    // ...
    Tourze\ConditionSystemBundle\ConditionSystemBundle::class => ['all' => true],
];

1. Create a custom condition handler:

use Tourze\ConditionSystemBundle\Handler\AbstractConditionHandler;
use Tourze\ConditionSystemBundle\Interface\ConditionInterface;
use Tourze\ConditionSystemBundle\ValueObject\EvaluationContext;
use Tourze\ConditionSystemBundle\ValueObject\EvaluationResult;

class MyCustomConditionHandler extends AbstractConditionHandler
{
    public function getType(): string
    {
        return 'my_custom_condition';
    }

    public function evaluate(ConditionInterface $condition, EvaluationContext $context): EvaluationResult
    {
        // Your evaluation logic here
        $passed = true; // Determine based on your logic
        
        return $passed 
            ? EvaluationResult::pass()
            : EvaluationResult::fail(['Condition not met']);
    }
}

1. Use the condition manager:

use Tourze\ConditionSystemBundle\Service\ConditionManagerService;

// Create a condition
$condition = $conditionManager->createCondition($subject, 'my_custom_condition', [
    'threshold' => 100,
    'operator' => '>='
]);

// Evaluate a condition
$context = new EvaluationContext($actor, ['value' => 150]);
$result = $conditionManager->evaluateCondition($condition, $context);

if ($result->isPassed()) {
    // Condition passed
} else {
    // Condition failed
    $errors = $result->getMessages();
}

Configuration

Dependencies

This bundle depends on:

• tourze/doctrine-timestamp-bundle: Provides timestamp functionality for entities
• tourze/enum-extra: Enhanced enum support

Advanced Usage

Condition Triggers

The bundle supports different condition triggers through the ConditionTrigger enum. You can filter available condition types by trigger:

$availableTypes = $conditionManager->getAvailableConditionTypes(ConditionTrigger::BEFORE_ACTION);

Batch Evaluation

Evaluate multiple conditions at once:

$results = $conditionManager->evaluateConditions($conditions, $context);

Testing

Run the test suite:

./vendor/bin/phpunit packages/condition-system-bundle/tests
