Helper classes offer functionalities for many features in Magento 2 stores. With Magento 2, the Helper can be called in controllers, models, views and other helpers.<\/p>\n\n\n\n
The below code can be used when you want to have helper\u2019s data in .phtml file in Magento 2.<\/p>\n\n\n\n
Making changes in the default Magento 2 files is not advisable and that\u2019s when the Magento 2 Helper class comes in picture to override the core files.<\/p>\n\n\n\n
The programmatic method to call helper function in phtml in Magento 2 as given below can be helpful to implement custom functionalities and enhance the store features!<\/p>\n\n\n\n
1. Call directly helper class<\/p>\n\n\n\n
$helper = $this->helper([Vendor]\\[Module]\\Helper\\Data);\n $values = $helper->HelperMethod();<\/pre>\n\n\n\n2. Using block class<\/p>\n\n\n\n
<?php \n\nnamespace [Vendoe]\\[Module]\\Block;\n\nclass BlockName extends \\Magento\\Framework\\View\\Element\\Template\n{\n protected $helper;\n\n public function __construct(\n ....\n [Vendor]\\[Module]\\Helper\\Data $helperData,\n ....\n) {\n ....\n $this->helper = $helperData;\n ....\n}\n\npublic function yourMethod()\n{\n return $this->helper->methodName();\n}\n\n}<\/pre>\n\n\n\nIf you want to call block in template file like display.phtml, write $block->yourMethod(); Here, BlockName class is block that renders the template display.phtml file.<\/p>\n\n\n\n
That\u2019s it.<\/p>\n\n\n\n
