Question

我创建了一个新模块，我在IndexController.php app/code/local/Ashfame/Helloblock/controllers/IndexController.php中通过以下方法创建了一个块。{/ 1}}

class Ashfame_Helloblock_IndexController extends Mage_Core_Controller_Front_Action {

    public function indexAction() {
        // this works fine
        $block = new Ashfame_Helloblock_Block_Helloblock();
        echo $block->toHtml();
    }

    public function layoutAction() {
        // this doesn't work
        $layout = Mage::getSingleton('core/layout');
        $block = $layout->createBlock('ashfame_helloblock/helloblock','root');
        var_dump( $block ); // this returns false
        echo $block->toHtml();
    }
}

我的Block类为Ashfame_Helloblock_Block_Helloblock，位于app/code/local/Ashfame/Helloblock/Block/Helloblock.php

由于$block中的layoutAction()为false，因此PHP会引发错误Call to a member function toHtml() on a non-object

在调试时我发现magento正在弄清楚类名错误。它在mage_Ashfame_helloblock_block内找出了getGroupedClassName()的班级名称。

这里有什么问题？

我认为问题出在您的配置文件中。在app/code/local/Ashfame/Helloblock/etc/config.xml，您应该：

<config>
  ...
  <global>
    ...
    <blocks>
        <ashfame_helloblock>
             <class>Ashfame_Helloblock_Block</class>
        </ashfame_helloblock>
    </blocks>
  </global>
</config>
