Magento 2 create  and use helper

Using helper you can put your methods in there that you have no idea where to put them. For example if you want create the thumbnail of image you use the helper method. The method you don’t know where to put put in helper class.

Now creating the helper and use of it.

Create Helper folder in module directory.



namespace QaisarSatti\HelloWorld\Helper

 

Now create the your helper class what name you want to put.In my case i will use Data file. Now the complete path will be.

namespace QaisarSatti\HelloWorld\Helper\Data.php



This file will be extend with.



 \Magento\Framework\App\Helper\AbstractHelper



Now create helper Data class.

 


<?php

/**

* Simple Hello World Module

*

* @category QaisarSatti

* @package QaisarSatti_HelloWorld

* @author Muhammad Qaisar Satti

* @Email [email protected]

*

*/


namespace QaisarSatti\HelloWorld\Helper;



use Magento\Store\Model\Store;



class Data extends \Magento\Framework\App\Helper\AbstractHelper

{



public function getTitle()

{

return  'First Hello World Module';

}

}

Now we will use helper method  in our block.

<?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 $_helper;

public function __construct(

\QaisarSatti\HelloWorld\Helper\Data $_helper,

) {



$this->_helper=$_helper;



}

public function _prepareLayout()

{

parent::_prepareLayout();

$this->pageConfig->getTitle()->set($this->_helper->getTitle());

return $this;

}

}

I am assuming that you are already familiar with magento 2 and has the know how, how things work in magento 2. So i will directly switch to our topic, and if you are not familiar please start from the basics.Having said that lets come to our topic, so if you are doing the custom theme then you must know how to Override default theme template files in magento 2,in your custom theme.And if you want to override all the files then simply go to.

vendor/magento/module-theme/view/frontend/

And copy the templates folder in your theme. In my case theme name is “theme”. So go to my theme folder and create the Magento_Theme Folder. And paste the templates folder there. Now your theme structure will look like this.

app/design/frontend/QaisarSatti/theme/Magento_Theme/templates

If you want to override the single file like header.phtml. Then copy the file from

vendor/magento/module-theme/view/frontend/templates/html/header.phtml

Paste it in your theme.And the file structure then will look like this

app/design/frontend/QaisarSatti/theme/Magento_Theme/templates/html/header.phtml
