Custom Risk Rules

Shopware 5.1.2 introduced a new event to provide custom risk rules: Shopware_Modules_Admin_Execute_Risk_Rule_sRisk[RiskName].

Extend Risk Management Backend Module

To add a new risk rule to the ExtJS store used by the backend module we use the smarty block backend/risk_management/store/risk/data that can be found in themes/Backend/ExtJs/backend/risk_management/store/risks.js.

<?php
// SwagCustomRiskRule/Subscriber/RiskManagement.php
namespace SwagCustomRiskRule\Subscriber;

use Enlight\Event\SubscriberInterface;

class RiskManagement implements SubscriberInterface
{
    /*
     * @var  $pluginPath string
     */
    private $pluginPath;
    /**
     * @param $pluginPath
     */
    public function __construct($pluginPath)
    {
        $this->pluginPath = $pluginPath;
    }
    /**
     * @return array
     */
    public static function getSubscribedEvents()
    {
        return [
            'Enlight_Controller_Action_PostDispatchSecure_Backend_RiskManagement' => 'onRiskManagementBackend'
        ];
    }
    public function onRiskManagementBackend(\Enlight_Event_EventArgs $args)
    {
        /** @var \Shopware_Controllers_Backend_Customer $controller */
        $controller = $args->get('subject');

        $view = $controller->View();
        $request = $controller->Request();

        $view->addTemplateDir($this->pluginPath . '/Resources/views');

        if ($request->getActionName() == 'load') {
            $view->extendsTemplate('backend/swag_custom_risk_rule/store/risks.js');
        }
    }
}

The file SwagCustomRiskRule/Resources/views/backend/my_risk_rule/store/risks.js adds a new entry to the existing store:

// SwagCustomRiskRule/Resources/views/backend/my_risk_rule/store/risks.js

//{block name="backend/risk_management/store/risk/data"}
//{$smarty.block.parent}
{ description: 'My Custom Rule', value: 'MyCustomRule' },
//{/block}

Handle custom Risk Rule

Given the new rule is named MyCustomRule the event we have subscribed to is Shopware_Modules_Admin_Execute_Risk_Rule_sRiskMyCustomRule.

// extend existing subscriber or define a new one

public static function getSubscribedEvents()
{
    return [
        'Shopware_Modules_Admin_Execute_Risk_Rule_sRiskMyCustomRule' => 'onMyCustomRule'
    ];
}

In the event callback we have access to the the name of the rule, the user, the basket and to the value:

/**
 * @param Enlight_Event_EventArgs $args
 * @return bool
 */
public function onMyCustomRule(Enlight_Event_EventArgs $args)
{
    $rule   = $args->get('rule');
    $user   = $args->get('user');
    $basket = $args->get('basket');
    $value  = $args->get('value');

    if ($basket['AmountNumeric'] > $value) {
        return true; // it's a risky customer
    }

    return false;
}
