magento - '无效块类型'异常

[英]magento - 'invalid block type' exception

我在自己的Customer模块中创建了一个新块,这里是config.xml:

<?xml version="1.0"?>
<config>
    <modules>
        <Nauba_Customer>
            <version>1.6.2.0.3</version>
        </Nauba_Customer>
    </modules>
    <global>
        <resources>
            <nauba_customer_setup>
                <setup>
                    <module>Nauba_Customer</module>
                </setup>
            </nauba_customer_setup>
        </resources>
        <blocks>
            <nauba_customer>
                <class>Nauba_Customer_Block</class>
            </nauba_customer>
            <customer>
                <rewrite>
                    <form_register>Nauba_Customer_Block_Form_Register</form_register>
                </rewrite>  
            </customer>
        </blocks>  
        <models>
            <customer>
                <rewrite>
                    <customer>Nauba_Customer_Model_Customer</customer>
                </rewrite>
            </customer>
        </models>    
    </global>  
    <frontend>
        <routers>
            <customer>
                <args>
                    <modules>
                        <Nauba_Customer before="Mage_Customer">Nauba_Customer</Nauba_Customer>
                    </modules>
                </args>
            </customer>
        </routers>
    </frontend>         
</config>

现在我想在主页中调用它,所以我在page.xml布局中指定了它:

<!-- this is only the home page section -->


<page_homepage translate="label">
    <label>Homepage</label>
    <reference name="root">
        <!--reference name="head">
            <action method="removeItem"><type>skin_css</type><name>css/styles.css</name></action>
            <action method="removeItem"><type>skin_css</type><name>css/styles-ie.css</name></action>
            <action method="removeItem"><type>skin_css</type><name>css/widgets.css</name></action>
            <action method="removeItem"><type>skin_css</type><name>css/print.css</name></action>                
        </reference-->

        <block type="page/html" name="category_links" template="page/html/category_links.phtml" />

        <block type="cms/block" name="homepage_slider_image_1" as="homepage_slider_image_1">
            <action method="setBlockId"><block_id>homepage_slider_image_1</block_id></action>
        </block>
        <block type="cms/block" name="homepage_slider_image_2" as="homepage_slider_image_2">
            <action method="setBlockId"><block_id>homepage_slider_image_2</block_id></action>
        </block>
        <block type="cms/block" name="homepage_slider_image_3" as="homepage_slider_image_3">
            <action method="setBlockId"><block_id>homepage_slider_image_3</block_id></action>
        </block>
        <block type="cms/block" name="homepage_slider_image_4" as="homepage_slider_image_4">
            <action method="setBlockId"><block_id>homepage_slider_image_4</block_id></action>
        </block>

        <block type="cms/block" name="homepage_event_banner_1" as="homepage_event_banner_1">
            <action method="setBlockId"><block_id>homepage_event_banner_1</block_id></action>
        </block>
        <block type="cms/block" name="homepage_event_banner_2" as="homepage_event_banner_2">
            <action method="setBlockId"><block_id>homepage_event_banner_2</block_id></action>
        </block>
        <block type="cms/block" name="homepage_event_banner_3" as="homepage_event_banner_3">
            <action method="setBlockId"><block_id>homepage_event_banner_3</block_id></action>
        </block>
                    <block type="nauba_customer/list_ordercrosssell" name="ordercrosssell" as="ordercrosssell" template="nauba_customer/list/ordercrosssell.phtml">   

                    </block>
        <action method="setTemplate"><template>page/home.phtml</template></action>
        <!-- Mark root page block that template is applied -->
        <action method="setIsHandle"><applied>1</applied></action>
        <action method="setLayoutCode"><name>page_homepage</name></action>
    </reference>        
</page_homepage>   

但是当我在主页模板中调用它时,它不起作用:

($this->getChildHtml('ordercrosssell'))

我也尝试通过以下方式创建它:

$this->getLayout()->createBlock('ordercrosssell')

但它引发了这个异常' 无效块类型 '。 任何帮助?

createBlock()方法将接受整个块别名( nauba_customer/list_ordercrosssell ),而不仅仅是ordercrosssell getChildHtml()只能接受ordercrosssell的原因是因为子块的名称是在布局xml中定义的。

不完全确定layout.xml可能有什么问题,但你应该在你的别名中删除下划线。 所以代替nauba_customer只需要使用naubacustomer或理想情况下比使用naubacustomer东西稍微短一些。

我不是百分之百确定它是否是一个问题,但总的来说,最好遵循现有的约定,因为@Herve提到了下划线与类别名中的斜杠,b / c事情可能会有点毛茸茸。

在某些情况下(Magento 1.9),如果我们忘记在块PHP文件中使用构造函数然后放入它,问题将得到修复:

 protected function _construct()
    {
        parent::_construct();
    }
