我正在Magento2中创建自定义模块。我想在phtml文件中调用块函数。但这并不奏效。请帮帮我.
这是我在adminhtml文件夹文件中的块。
namespace Question\Topic\Block\Adminhtml;
class Topic extends \Magento\Framework\View\Element\Template {
public function getSample() {
return "abhishek";
}
}
view/adminHTML/layout中的topic_order_view.xml文件是
<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../../../../lib/internal/Magento/Framework/View/Layout/etc/page_configuration.xsd">
<body>
<referenceContainer name="content">
<block class="Magento\Framework\View\Element\Template" name="view" template="Questions_Topic::view.phtml" />
</referenceContainer>
</body>
</page>
下面是我的控制器，位于controller/adminHTML/order/view.php中--
namespace Question\Topic\Controller\Adminhtml\Order;
use Magento\Backend\App\Action;
use Magento\Backend\App\Action\Context;
use Magento\Framework\View\Result\PageFactory;
use Magento\Framework\App\Config\ScopeConfigInterface;
class View extends \Magento\Backend\App\Action
{
/**
* @var PageFactory
*/
protected $resultPageFactory;
/**
* @var scopeConfig
* Needed to retrieve config values
*/
protected $scopeConfig;
public function __construct(
Context $context,
PageFactory $resultPageFactory,
ScopeConfigInterface $scopeConfig // Needed to retrieve config values
) {
parent::__construct($context);
$this->resultPageFactory = $resultPageFactory;
$this->scopeConfig = $scopeConfig; // Needed to retrieve config values
}
public function execute()
{
$resultPage = $this->resultPageFactory->create();
$resultPage->getConfig()->getTitle()->prepend(__('Orders')); //
return $resultPage;
}
}
view/adminHTML/templates/order/view.phtml中的我的view.phtml文件
<?php
//echo $this->getSample();
echo $block->getSample();
?>
<h1>Hello </h1>
显示的是“你好”字。但不回显上述分组码
事先谢谢..
您应该“告诉”您的布局您想要传递给内容的块。
<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
<body>
<referenceContainer name="content">
<block class="Question\Topic\Block\Adminhtml\Topic" name="question.topic.view" template="Questions_Topic::view.phtml" />
</referenceContainer>
</body>
</page>
