Online multi-channel retailing can be interpreted as an approach to sale online store products on additional platforms like Instagram, Facebook, relevant marketplaces, etc.<\/p>\n\n\n\n
For Magento 2 stores going for this approach needs to offer an excellent shopping experience. For example, a visitor checks your product on a Facebook shop and decides to buy it. On clicking it, he should be redirected to your store, and the product must be added to the cart for checkout.<\/p>\n\n\n\n
However, Magento 2 needs to identify the product that is to be added to the cart. And to do so, you need to pass parameter to URL in Magento 2.<\/p>\n\n\n\n
Implement the below method to identify the particular product by passing a parameter through URL:<\/p>\n\n\n\n
<?php\nnamespace Vendor\\Module\\Helper;\n\nuse Magento\\Framework\\App\\Helper\\Context;\nuse Magento\\Framework\\UrlInterface;\n\nclass Data extends AbstractHelper\n{\n protected $urlBuilder;\n \n public function __construct(\n Context $context,\n UrlInterface $urlBuilder\n )\n {\n $this->urlBuilder = $urlBuilder;\n parent::__construct($context);\n }\n\n public function GetParamUrl()\n {\n $queryParams = [\n 'param_1' => value1, \/\/ value for parameter\n 'param_2' => value2\n ];\n \n return $this->urlBuilder->getUrl('route\/controller\/action', ['_current' => true,'_use_rewrite' => true, '_query' => $queryParams]);\n \/\/Ex: $this->urlBuilder->getUrl('custom\/addcart\/index', ['_current' => true,'_use_rewrite' => true, '_query' => $queryParams]);\n }\n}<\/pre>\n\n\n\nNote:<\/strong> For phtml file, you can use:<\/p>\n\n\n\n$block->getUrl('route\/controller\/action',['param'=>'value'])<\/pre>\n\n\n\nThat\u2019s all.<\/p>\n\n\n\n
