If you are wondering how to get/print the information of the current product and even the current category, the topic is all things you need to find. Two steps are recommended in this topic, please get them and do any thing you need.

Overview

Step 1: Declare in Mageplaza_HelloWorld
Step 2: Print out the current product in the template phtml file
Step 3: Print out current category in the template phtml file

Step 1: Declare in Mageplaza_HelloWorld

You will use a block class of the module Mageplaza_HelloWorld, then possibly inject the object of \Magento\Framework\Registry in the constructor of the module’s block class.

app/code/Mageplaza/HelloWorld/Block/HelloWorld.php

<?php
namespace Mageplaza\HelloWorld\Block;
class HelloWorld extends \Magento\Framework\View\Element\Template
{
        protected $_registry;
        
    public function __construct(
        \Magento\Backend\Block\Template\Context $context,        
        \Magento\Framework\Registry $registry,
        array $data = []
    )
    {        
        $this->_registry = $registry;
        parent::__construct($context, $data);
    }
    
    public function _prepareLayout()
    {
        return parent::_prepareLayout();
    }
    
    public function getCurrentCategory()
    {        
        return $this->_registry->registry('current_category');
    }
    
    public function getCurrentProduct()
    {        
        return $this->_registry->registry('current_product');
    }    
    
}
?>

Step 2: Get current product in the template `phtml` file

The current product includes the following information: name, sku, final price, url and associated category ids. And the current category comes with the information as name and url. Now please run the command to print out the current product and the current category.

$myBlock = \Magento\Framework\App\ObjectManager::getInstance()->get('Mageplaza\HelloWorld\Block\HelloWorld');
 

// print current product data
if ($currentProduct = $myBlock->getCurrentProduct()) {
    echo $currentProduct->getName() . '<br />';
    echo $currentProduct->getSku() . '<br />';
    echo $currentProduct->getFinalPrice() . '<br />';
    echo $currentProduct->getProductUrl() . '<br />';
    print_r ($currentProduct->getCategoryIds()) . '<br />';    
}

Step 3: Get current category in the template `phtml` file

$myBlock = \Magento\Framework\App\ObjectManager::getInstance()->get('Mageplaza\HelloWorld\Block\HelloWorld');
 
// print current category data
if ($currentCategory = $myBlock->getCurrentCategory()) {    
    echo $currentCategory->getName() . '<br />';
    echo $currentCategory->getUrl() . '<br />';        
}
