If you want to open a new window when you click on the button & use the empty layout in it then you have to follow the below steps.
Step 1: Place a new button in the admin and you have to make the on-click as per the below code.
|
1 2 3 4 5 6 7 8 9 10 |
$this->setChild( 'add_print_button', $this->getLayout()->createBlock('Magento\Backend\Block\Widget\Button')->setData( [ 'label' => __('Print Registry'), 'onclick' => "window.open('".$printUrl."','_blank', 'toolbar=yes,scrollbars=yes,resizable=yes')", 'class' => 'task action-primary registry-print', ] ) ); |
Step 2: Now in your controller you have to copy-paste the below code in the execute method to display your content in the empty layout.
|
1 2 3 4 5 6 7 8 9 10 11 |
/** @var \Magento\Backend\Model\View\Result\Page $resultPage */ $resultPage = $this->resultFactory->create(ResultFactory::TYPE_PAGE); $registryId = $this->getRequest()->getParam('registry_id'); $registry = $this->registryFactory->create()->load($registryId); $items = $this->getPrintItems($registryId); $resultPage->addHandle('admin-empty'); $this->_addContent($resultPage->getLayout()->createBlock('\Mirasvit\Giftr\Block\Mail\Printitems')->setRegistry($registry)->setPrintItems($items)); return $resultPage; |
That’s it. Now I can see content in the empty layout page in the Magento admin side by clicking the button.
