Events #

Events can be used to extend the functionality of Postie.

Rates related events #

The beforeFetchRates event #

The event raised before the rates are fetched. Primarily used to modify the package dimensions, or store information.

use verbb\postie\base\Provider;
use verbb\postie\events\FetchRatesEvent;
use verbb\postie\providers\USPS;
use yii\base\Event;

Event::on(USPS::class, Provider::EVENT_BEFORE_FETCH_RATES, function(FetchRatesEvent $event) {
    $storeLocation = $event->storeLocation;
    $dimensions = $event->dimensions;
});

The modifyPayload event #

The event raised before the payload is sent to a provider. You can modify the payload to suit your needs before being sent.

use verbb\postie\base\Provider;
use verbb\postie\events\ModifyPayloadEvent;
use verbb\postie\providers\USPS;
use yii\base\Event;

Event::on(USPS::class, Provider::EVENT_MODIFY_PAYLOAD, function(ModifyPayloadEvent $event) {
    $provider = $event->provider;
    $payload = $event->payload;
    $order = $event->order;

    // To modify the payload, directly modify the variable via `$event->payload = ...`
});

The modifyRates event #

Plugins can get notified when rates are fetched from a provider. You can modify these rates, or access anything in the response from the provider. Be sure to modify the rates property.

use verbb\postie\base\Provider;
use verbb\postie\events\ModifyRatesEvent;
use verbb\postie\providers\USPS;
use yii\base\Event;

Event::on(USPS::class, Provider::EVENT_MODIFY_RATES, function(ModifyRatesEvent $event) {
    $rates = $event->rates; // The calculated rates from Postie
    $response = $event->response; // The raw response from the provider's API

    // To modify the rates, directly modify the variable via `$event->rates = ...`

});

The beforePackOrder event #

Plugins can get notified before the order contents are packed in boxes.

use verbb\postie\base\Provider;
use verbb\postie\events\PackOrderEvent;
use verbb\postie\providers\USPS;
use yii\base\Event;

Event::on(USPS::class, Provider::EVENT_BEFORE_PACK_ORDER, function(PackOrderEvent $event) {
    $order = $event->order;
    $packer = $event->packer;
});

The afterPackOrder event #

Plugins can get notified after the order contents are packed in boxes.

use verbb\postie\base\Provider;
use verbb\postie\events\PackOrderEvent;
use verbb\postie\providers\USPS;
use yii\base\Event;

Event::on(USPS::class, Provider::EVENT_AFTER_PACK_ORDER, function(PackOrderEvent $event) {
    $order = $event->order;
    $packedBoxes = $event->packedBoxes;
    $packer = $event->packer;
});

The modifyShippingRule event #

Plugins can modify anything about a shipping rule for a shipping method. This includes the description, price and more.

use verbb\postie\events\ModifyShippingRuleEvent;
use verbb\postie\models\ShippingMethod;
use yii\base\Event;

Event::on(ShippingMethod::class, ShippingMethod::EVENT_MODIFY_SHIPPING_RULE, function(ModifyShippingRuleEvent $event) {
    // To modify the rule, directly modify the variable via `$event->shippingRule = ...`
});

The modifyShippingMethods event #

Plugins can modify the returned shipping methods, after they have been created from the provider.

use verbb\postie\base\Provider;
use verbb\postie\events\ModifyShippingMethodsEvent;
use verbb\postie\providers\USPS;
use yii\base\Event;

Event::on(USPS::class, Provider::EVENT_MODIFY_SHIPPING_METHODS, function(ModifyShippingMethodsEvent $event) {
    $provider = $event->provider;
    $shippingMethods = $event->shippingMethods;
    $order = $event->order;

    // To modify the shipping methods, directly modify the variable via `$event->shippingMethods = ...`
});

The beforeRegisterShippingMethods event #

Plugins can modify the returned shipping methods, after they have been fetched from all providers. This differs from the modifyShippingMethods event as it is not per-provider.

use verbb\postie\events\ModifyShippingMethodsEvent;
use verbb\postie\services\Service;
use yii\base\Event;

Event::on(Service::class, Service::EVENT_BEFORE_REGISTER_SHIPPING_METHODS, function(ModifyShippingMethodsEvent $event) {
    $shippingMethods = $event->shippingMethods;
    $order = $event->order;

    // To modify the shipping methods, directly modify the variable via `$event->shippingMethods = ...`
});

The modifyVariantQuery event #

Plugins can modify the Variant query for Postie's settings. Postie will by default look at all variants across your site and report on whether weight and dimension values are set. You can modify this query to suit your needs.

use verbb\postie\controllers\PluginController;
use verbb\postie\events\ModifyShippableVariantsEvent;
use yii\base\Event;

Event::on(PluginController::class, PluginController::EVENT_MODIFY_VARIANT_QUERY, function(ModifyShippableVariantsEvent $event) {
    // To modify the query, directly modify the variable via `$event->query = ...`
});
