Magento 2 call any block function in phtml

This tutorial is about magento 2 call block function in phtml. First of all i assume that you are familiar with magento 2 and hence you are at this level where you want to know how in magento 2 call any block function in phtml. Above all if you are not familiar and are looking for basics please look for magento 2 basic tutorials.

Seems like i have conveyed my message so lets start our tutorial and focus on our topic. For example if you want to call your custom block function in product list.phtml?.How can we do it? I will try to explain it in a simple way.

Call custom block funtion

Lets have a look at the code.
For example your block class is as below

<?php
namespace QaisarSatti\HelloWorld\Block;
use Magento\Framework\View\Element\Template;

class Test extends Template
{
    public function getMyCustomMethod()
    {
        return 'Get Your custom method';
    }
}

Then in any phtml file,you can use the following code to get method of this block.

<?php
$blockObj= $block->getLayout()->createBlock('QaisarSatti\HelloWorld\Block\Test');
echo $blockObj->getMyCustomMethod();
?>

That is how it can be done.Certainly, i have tried to explain these codes and their logic in a simple way, i hope they help you learn in an easy and better way. That’s it from this tutorial.

Since these tutorials are for learning purpose please feel free to drop any suggestions or queries in comments section. That will definitely be highly appreciated.

Magento 2 get media path

Today we discuss about Magento 2 get media path .This tutorial include how to get media path in your block or phtml file. There are two ways to do it. One is factory method and other is use object manager. So let start with our example.

Factory Method

In this example we will get media path. First your need to inject \Magento\Store\Model\StoreManagerInterface.

<?php
/**
* Simple Hello World Module
*
* @category QaisarSatti
* @package QaisarSatti_HelloWorld
* @author Muhammad Qaisar Satti
* @Email [email protected]
*
*/

namespace QaisarSatti\HelloWorld\Block;
class HelloWorld extends \Magento\Framework\View\Element\Template
{
protected $storeManager;

public function __construct(
   
    \Magento\Store\Model\StoreManagerInterface $storeManager,
   
) {
   
    $this->storeManager = $storeManager;
   
}

public function getMediaUrl()
{
    return $mediaUrl = $this->storeManager
                     ->getStore()
                     ->getBaseUrl(\Magento\Framework\UrlInterface::URL_TYPE_MEDIA);
   
}


}

Object Manager

In this example we will get media path. Using object manager is not recommended.

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
echo $objectManager->get('Magento\Store\Model\StoreManagerInterface')
                    ->getStore()
                    ->getBaseUrl(\Magento\Framework\UrlInterface::URL_TYPE_MEDIA);

    }

public function getGroupId(){

   //Get current group
         echo $this->_customerSession->getCustomer()->getId();  // get customer id
         echo $this->_customerSession->getCustomer()->getName();  // get  customer Full Name
         echo $this->_customerSession->getCustomer()->getEmail(); // get customer Email
else:

   echo “no logged in”;            


endif;

}

Object Manager

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$customerSession = $objectManager->create('Magento\Customer\Model\Session');

if ($customerSession->isLoggedIn()):
   //Get current group
         echo $this->_customerSession->getCustomer()->getId();  // get customer id
         echo $customerSession->getCustomer()->getName();  // get  customer Full Name
