Magento 2：将参数从 controller 传递到 phtml 视图

Question

There's a way to passing parameters from controller to phtml view using PageFactory class?

Controller code:

use Magento\Backend\App\Action;
use Magento\Backend\App\Action\Context;
use Magento\Framework\App\Action\HttpGetActionInterface;
use Magento\Framework\View\Result\Page;
use Magento\Framework\View\Result\PageFactory;
use MyModule\Services\Service\CurlService;

class Index extends Action implements HttpGetActionInterface
{

protected $resultPageFactory;
protected $curlService;

public function __construct(
    Context $context,
    PageFactory $resultPageFactory,
    CurlService $curlService
) {
    parent::__construct($context);

    $this->resultPageFactory = $resultPageFactory;
    $this->curlService = $curlService;
}

public function execute()
{
    if(isset($_GET['action']) && $_GET['action'] == true)
    {
        $response = json_decode($this->curlService->response());
        switch($response->status)
        {
            case 'ok': $msgReturn = 'Successfull'; break;
            default:   $msgReturn = 'Error'; break;
        }
    }
    
    $resultPage = $this->resultPageFactory->create();
    $resultPage->setActiveMenu(static::MENU_ID);
    
    $resultPage->getConfig()->getTitle()->prepend(__('Page Title'));
    
    return $resultPage;
}

I need passing $msgReturn using PageFactory to the corresponding view

Answer 1

To add data to your phtml block, simply enter this example in the controller where you set your data.

use Magento\Framework\View\Result\PageFactory;

$page = $this->pageFactory->create();
$block = $page->getLayout()->getBlock('block_alias');
$block->setData('name_var', $data);

And then in the phtml file

$data = $block->getData('name_var');
