Question

我收到如下错误

Recoverable Error: Argument 1 passed to Mage_Adminhtml_Controller_Action::_addContent() must be an instance of Mage_Core_Block_Abstract, boolean given,

我的indexAction代码如下所示

public function indexAction()
    {
        // instantiate the grid container
        $brandBlock = $this->getLayout()
            ->createBlock('digitech_brandlogo_adminhtml/brandlogo');

        // Add the grid container as the only item on this page
        $this->loadLayout()
            ->_addContent($brandBlock)
            ->renderLayout();
    }

在这种情况下，我的问题是“

是什么意思

$brandBlock = $this->getLayout()
                ->createBlock('digitech_brandlogo_adminhtml/brandlogo');

“??

我想知道关于块和布局结构/安排。

对不起，迟到的回答可能是这个帮助别人您可以使用此代码，请将“my_block_name_here”和“activecodeline / developer.phtml”替换为您的块名称和模板路径

public function indexAction()
{
//Get current layout state
$this->loadLayout();

$block = $this->getLayout()->createBlock(
'Mage_Core_Block_Template',
'my_block_name_here',
array('template' => 'activecodeline/developer.phtml')
);

$this->getLayout()->getBlock('content')->append($block);

$this->renderLayout();
}

在Magento管理面板中显示一个块
