Magento - 2 个或更多观察者关注同一事件

Question

我的 2 个观察者正在观察相同的 sales_order_shipment_save_before 事件。 ModuleA 是我首先创建的，然后我创建了 ModuleB

现在只有 ModuleB 的观察者被调用，而不是 ModuleA >。

请让我知道我该如何解决这个问题，并且两位观察员都被召集了。

ModuleA

<?xml version="1.0"?>
<config>
    <global>

            <shipmentsave>

        return;
    }
}

问候， 索拉布

Answer 1

没有时间对此进行测试，但乍一看我会尝试使

<shipmentsave>

每个模块变得不同。类似

    <observers>
      <shipmentsave>
        <type>singleton</type>
        <class>bshipment/observer</class>
        <method>salesOrderShipmentSaveBefore</method>
      </shipmentsave>
    </observers>

和

    <observers>
      <bshipmentsave>
        <type>singleton</type>
        <class>bshipment/observer</class>
        <method>salesOrderShipmentSaveBefore</method>
      </bshipmentsave>
    </observers>

Answer 2

每个观察者都应该有一个唯一的名字。
在代码中，两个观察者具有相同的名称。
因此，为每个观察者指定唯一的名称。

Answer 3

我认为你错过了一些东西。您可以使用事件的观察者来调用尽可能多的函数。但对于每个事件，观察者的方法名称及其 ID 都应该不同。

<events>
    <sales_order_shipment_save_before>
        <observers>
            <shipmentsave>
                <type>singleton</type>
                <class>shipmentsave/observer</class>
                <method>salesOrderShipmentSaveBefore</method>
            </shipmentsave>
        </observers>
    </sales_order_shipment_save_before>
</events>

<events>
    <sales_order_shipment_save_before>
        <observers>
            <shipmentsave>
                <type>singleton</type>
                <class>bshipment/observer</class>
                <method>salesOrderShipmentSaveBefore</method>
            </shipmentsave>
        </observers>
    </sales_order_shipment_save_before>
</events>

您可以在 XML 中看到 id shipmentsave 和方法 salesOrderShipmentSaveBefore 是相同的。

只要改变这个就可以了。
