'Mage_Core_Exception'帶有消息'Invalid block type：in /var/www/magento1/app/Mage.php:595

當我剛創建一個簡單的Hello World模塊時，我在日誌文件中得到了這個異常。'Mage_Core_Exception'帶有消息'Invalid block type：in /var/www/magento1/app/Mage.php:595

exception 'Mage_Core_Exception' with message 'Invalid block type: MyCompanyName_HelloWorld_Block_Helloworld' in /var/www/magento1/app/Mage.php:595

配置文件等等/ config.xml中

<?xml version="1.0"?> 
<config> 
    <modules> 
     <MyCompanyName_HelloWorld> 
      <version>0.0.1</version> 
     </MyCompanyName_HelloWorld> 
    </modules> 
    <global> 
     <blocks> 
      <helloworld> 
       <class>MyCompanyName_HelloWorld_Block</class>     
      </helloworld> 
     </blocks> 
    </global> 
    <frontend> 
     <routers> 
      <helloworld> 
       <use>standard</use> 
       <args> 
        <module>MyCompanyName_HelloWorld</module> 
        <frontName>helloworld</frontName> 
       </args> 
      </helloworld> 
     </routers> 
     <layout> 
      <updates> 
       <helloworld> 
        <file>helloworld.xml</file> 
       </helloworld> 
      </updates> 
     </layout> 
    </frontend>  
</config>

佈局文件helloworld.xml

<?xml version="1.0"?> 
<layout version="0.1.0"> 
    <helloworld_index_index> 
     <reference name="root"> 
      <action method="setTemplate"><template>page/1column.phtml</template></action> 
     </reference> 
     <reference name="content"> 
     <!--<block type="core/template" name="helloworld" template="helloworld/helloworld.phtml"/> --> 
      <block type="helloworld/helloworld" name="helloworld.helloworld" template="helloworld/helloworld.phtml"/> 
     </reference> 
    </helloworld_index_index> 
</layout>

Block類文件HelloWorld.php

class MyCompanyName_HelloWorld_Block_HelloWorld extends Mage_Core_Block_Template { 

}

controlers/indexController的。 php

class MyCompanyName_HelloWorld_IndexController extends Mage_Core_Controller_Front_Action { 
    public function indexAction() { 
     //echo "We're echoing just to show that this is what's called, normally you'd have some kind of redirect going on here"; 
     $this->loadLayout();   
     $this->renderLayout(); 
    } 
}

應用程序的/ etc /模塊MyCompanyName_HelloWorld.xml

<?xml version="1.0"?> 
<config> 
    <modules> 
     <MyCompanyName_HelloWorld> 
      <active>true</active> 
      <codePool>local</codePool> 
     </MyCompanyName_HelloWorld> 
    </modules> 
</config>

請告訴我在哪裏，我在它錯過了的東西。在此先感謝..

阿米特貝拉是在正確的軌道。但是他的回答並不完全正確。類和文件名可以包含大寫字母，但這個字母在佈局中也應該是大寫。類名的第一個字母是一個例外 - 在類名中總是大寫，在佈局中總是小寫。

在如果類名是HelloWorld的，所以在佈局塊型應該的HelloWorld/的helloWorld你這樣的情況：

<block type="helloworld/helloWorld" name="helloworld.helloworld" template="helloworld/helloworld.phtml"/>

更多專家答覆.....謝謝alexei –

我最近有同樣的問題，我的開發環境不關心這種情況出於某種原因，當我把它放到我的測試服務器上時，這個問題悄然升起。現在，如果我只知道我的虛擬機爲什麼不關心這個情況。 –

扯談，你block class name is wrong：

應該是Helloworld.php instead of HelloWorld.php.

W should be small letter

據Magento的，如果任何類文件中有兩個上字母的文件名是否應該explit到一個目錄和一個文件。

例如

In MyCompanyName_HelloWorld_Block_HelloWorld the class name after 

MyCompanyName_HelloWorld_Block is Hellword,Magenti split class 
into Hello is dir Word the class file

感謝阿米特只是我想再問一個很小的事情，我的塊級名稱'MyCompanyName_HelloWorld_Block_HelloWorld'是否正確或者它應該是「MyCompanyName_HelloWorld_Block_Helloworld」？我只是改變我的php文件名HelloWorld Helloworld –

MyCompanyName_HelloWorld_Block_Helloworld是正確的。塊類名是取決於文件名 –

'Mage_Core_Exception'帶有消息'Invalid block type：in /var/www/magento1/app/Mage.php:595
