Custom Price-Rule/Shipping-Rule/Notification-Rule Conditions

Adding Price-, Shipping- or Notification-Rule Conditions is the same for all of these types. They're only difference is the tag you use and Interface you need to implement for them.

Action Type	Tag	Interface/AbstractClass
Cart Price Rule	coreshop.cart_price_rule.condition	CoreShop\Component\Order\Cart\Rule\Condition\AbstractConditionChecker
Product Price Rule	coreshop.product_price_rule.condition	CoreShop\Component\Rule\Condition\ConditionCheckerInterface
Product Specific Price	coreshop.product_specific_price_rule.condition	CoreShop\Component\Rule\Condition\ConditionCheckerInterface
Shipping Rule	coreshop.shipping_rule.condition	CoreShop\Component\Shipping\Rule\Condition\CategoriesConditionChecker
Notification Rule	coreshop.notification_rule.condition	CoreShop\Component\Notification\Rule\Condition\AbstractConditionChecker

Example Adding a new Condition

Now, lets add a new Condition for Product Price Rules.

To do so, we first need to create a new class and implement the interface listed in the table above. For Product Price Rules, we need to use CoreShop\Component\Rule\Condition\ConditionCheckerInterface

//AppBundle/CoreShop/CustomCondition.php
namespace AppBundle\CoreShop;

use CoreShop\Component\Resource\Model\ResourceInterface;
use CoreShop\Component\Rule\Model\RuleInterface;

final class CustomCondition implements \CoreShop\Component\Rule\Condition\ConditionCheckerInterface
{
public function isValid(ResourceInterface $subject, RuleInterface $rule, array $configuration, array $params = []): bool
{
//return true if valid, false if not
return true;
}

We also need a FormType for the conditions configurations:

//AppBundle/Form/Type/CustomConditionType.php
namespace AppBundle\Form\Type;

final class CustomConditionType extends AbstractType
{
/**
* {@inheritdoc}
*/
public function buildForm(FormBuilderInterface $builder, array $options): void
{
$builder
->add('some_value', TextType::class)
;
}

With configuration, comes a Javascript file as well:

//AppBundle/Resources/public/pimcore/js/custom_condition.js

pimcore.registerNS('coreshop.product.pricerule.conditions.custom');
coreshop.product.pricerule.conditions.custom = Class.create(coreshop.rules.conditions.abstract, {

    type: 'custom',

    getForm: function () {
        var some_value = 0;
        var me = this;

        if (this.data) {
            some_value = this.data.some_value / 100;
        }

        var some_valueField = new Ext.form.NumberField({
            fieldLabel: t('custom'),
            name: 'some_value',
            value: some_value,
            decimalPrecision: 2
        });

        this.form = new Ext.form.Panel({
            items: [
                some_valueField
            ]
        });

        return this.form;
    }
});

Don't forget to run the following command afterwards to deploy it if needed. If you're using the latest symfony structure, omit the web.

bin/console assets:install

Registering the Custom Condition to the Container and load the Javascript File

We now need to create our Service Definition for our Custom Condition:

app.product_price_rule.custom_condition:
  class: AppBundle\CoreShop\CustomCondition
  tags:
    - { name: coreshop.product_price_rule.condition, type: custom, form-type: AppBundle\Form\Type\CustomConditionType }

and add this to your config.yml:

core_shop_product:
    pimcore_admin:
        js:
            custom_condition: '/bundles/app/pimcore/js/custom_condition.js'
