我一直在关注No Frills Magento布局书。所有示例都正常工作，直到本节：

本地/ Nofrills / Booklayout的/ etc / config.xml中：

本地/ Nofrills / BookLayout /砌块/ HelloWorld.php：

<?php
class Nofrills_Booklayout_Block_HelloWorld extends Mage_Core_Block_Template 
{
    public function _construct()
    {
        $this->setTemplate('helloworld.phtml');
        return parent::_construct();
    }

    public function _beforeToHtml()
    {
        $block_1 = new Mage_Core_Block_Text();
        $block_1->setText('The first sentence. ');
        $this->setChild('the_first', $block_1);

        $block_2 = new Mage_Core_Block_Text();
        $block_2->setText('The second sentence. ');
        $this->setChild('the_second', $block_2);
    }

    public function fetchTitle() 
    {
        return 'Hello Fancy World';
    }
}

本地/ Nofrills / Booklayout /控制器/ IndexController.php：

public function layoutAction()
{
    $layout = Mage::getSingleton('core/layout');
    $block = $this->getLayout()->createBlock('nofrills_booklayout/helloworld');
    echo $block->toHtml();
}

这让我：

Call to a member function toHtml() on a non-object in...

Answer 1

试试这个：

public function layoutAction()
{
    $this->loadLayout();
    $this->_addContent($this->getLayout()->createBlock('nofrills_booklayout/helloworld'));
    $this->renderLayout();
}

Answer 2

正如马吕斯在评论部分所说，改变＆＃34; helloworld＆＃34; to＆＃34; helloWorld＆＃34;让它成真。

尝试创建块时没有Frills Magento Layout错误
