Magento - 2个或更多的观察者在同一事件

2我的观察员观察到相同的事件sales_order_shipment_save_before。 ModuleA是我创建的第一个，然后我创建ModuleBMagento - 2个或更多的观察者在同一事件

现在只有ModuleB的观察员被称为，而不是ModuleA。

请让我知道如何解决这个问题，并且两个观察者都被调用。

ModuleA

<?xml version="1.0"?> 
<config> 
    <global> 
     <models> 
      <shipmentsave> 
       <class>My_Shipmentsave_Model</class>

         <method>salesOrderShipmentSaveBefore</method> 
        </shipmentsave> 
       </observers> 
      </sales_order_shipment_save_before> 
     </events> 
    </adminhtml> 
</config>

Observer.php

<?php 

    class My_Shipmentsave_Model_Observer 
{ 
    public function salesOrderShipmentSaveBefore(Varien_Event_Observer $observer) 
    { 
     $shipment = $observer->getEvent()->getShipment(); 
     return; 
    } 
}

ModuleB

请发表您的两个观察者规格（配置XML）。 – 2010-08-16 12:44:43

添加了xml和php – Saurabh 2010-08-16 17:47:10

没有时间来测试这一点，但乍一看我想尝试做

<shipmentsave>

不同的每个模块。像

<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>

这正是问题所在。每个事件只能有一个名为observer的实例。每个观察者都需要它自己的名字。我的标准是使用模块名称作为观察者名称。所以在这种情况下和。 – 2012-03-10 20:47:28

@Alan Storm，在你回答两年后，不接受，但它有效吗？我面临同样的问题，2个不同的模块，需要捕获相同的事件，第二个模块不工作。但如果我停用第一个然后第二个作品。 – Yaroslav 2012-09-28 07:50:56

这个答案应该被接受。由于观察员姓名必须是唯一的，因此'shipmentsave'和'bshipmentsave'将起作用。否则，读取的最后一个XML节点将简单地覆盖具有相同名称的以前的观察者。 – musicliftsme 2014-03-27 15:30:16

每个观察者的东西应该有一个唯一的名称。在代码中，两个观察者具有相同的名称。因此给每个观察者一个独特的名字。

我想你错过了一些想法，你可以使用observer来调用很多函数来完成一个事件。但对于每个事件观察者方法名称应该是不同的，也是它的ID。

<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 id shipmentsave和方法salesOrderShipmentSaveBefore中看到相同的结果。

只要改变这一点，你都完成了。
