However, if the appearance of your product page is not up to the mark, you can lose a lot of sales. An attractive front end of your store can make your customers stay and can help in boosting sales. The look of add to cart button also plays a vital role in making the product page look attractive.

Check it out!I will implement the procedure using a custom module. So let’s start by creating a custom module:

Configuration and Registration of Module
- Create module.xml in
app/code/Vendor/Mymodule/etc:
<?xml version="1.0"?>
<configxmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
<module name="Vendor_Mymodule" setup_version="1.0.0"></module>
</config>
- Create registration.php in
app/code/Vendor/Mymodule:
<?php
\Magento\Framework\Component\ComponentRegistrar::register(
\Magento\Framework\Component\ComponentRegistrar::MODULE,
'Vendor_Mymodule',
__DIR__
);
Copy addtocart.phtml File
Copy addtocart.phtml file from vendor/magento/module-catalog/view/frontend/templates/product/view paste this file in app/code/Vendor/Mymodule/view/frontend/templates/catalog/product/view.
Now create default.xml file in app/code/Vendor/Mymodule/view/frontend/layout and add this code in the file:
<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
<head>
<csssrc="Vendor_Mymodule::css/colorcart.css"/>
</head>
<body>
<referenceBlock name="product.info.addtocart">
<action method="setTemplate">
<argument name="template" xsi:type="string">Vendor_Mymodule::catalog/product/view/addtocart.phtml</argument>
</action>
</referenceBlock>
</body>
</page>
I have added colorcart.css file which I will use to customize add to cart button.
Edit addtocart.phtml
Now open addtocart.phtml file by going to app/code/Vendor/Mymodule/view/frontend/templates/catalog/product/view and add css class newcolor in the button tag:
<?php
/**
* Copyright © Magento, Inc. All rights reserved.
* See COPYING.txt for license details.
*/
/** @var $block \Magento\Catalog\Block\Product\View */
?>
<?php $_product = $block->getProduct(); ?>
<?php $buttonTitle = __('Add to Cart'); ?>
<?php if ($_product->isSaleable()) :?>
<div class="box-tocart">
<div class="fieldset">
<?php if ($block->shouldRenderQuantity()) :?>
<div class="field qty">
<label class="label" for="qty"><span><?= $block->escapeHtml(__('Qty')) ?></span></label>
<div class="control">
<input type="number"
name="qty"
id="qty"
min="0"
value="<?= $block->getProductDefaultQty() * 1 ?>"
title="<?= $block->escapeHtmlAttr(__('Qty')) ?>"
class="input-text qty"
data-validate="<?= $block->escapeHtml(json_encode($block->getQuantityValidators())) ?>"
/>
</div>
</div>
<?php endif; ?>
<div class="actions">
<button class=”newcolor” type="submit"
title="<?= $block->escapeHtmlAttr($buttonTitle) ?>"
class="action primary tocart"
id="product-addtocart-button" disabled>
<span><?= $block->escapeHtml($buttonTitle) ?></span>
</button>
<?= $block->getChildHtml('', true) ?>
</div>
</div>
</div>
<?php endif; ?>
<script type="text/x-magento-init">
{
"#product_addtocart_form": {
"Magento_Catalog/js/validate-product": {}
}
}
</script>
Create CSS file
Now create a css file colorcart.css in app/code/Vendor/Mymodule/view/frontend/web/css and add the following code in it:
.newcolor
{
background: #29487d !important;
box-shadow: 1px 5px 5px 1px rgba(66, 103, 178, 0.51);
font-size: 23px !important;
font-weight: bold !important;
border-radius: 10px;
height: 60px;
font-family: cursive !important;
}
Now go to your Magento 2 root directory through SSH terminal and run these commands:
php bin/magento setup:upgrade
php bin/magento setup:di:compile
php bin/magento setup:static-content:deploy -f
php bin/magento cache:flush
Launch the product’s front page and you will see the new design applied to the add to cart button:
Add products to cart using Quote Model
The AddToCart controller processes a GET request at ‘example/product/addToCart’ by retrieving product information from request parameters and adding it to the cart.
<?php
namespace Magenest\Example\Controller\Product;
use Magento\Framework\App\Action\Action;
use Magento\Framework\App\Action\Context;
use Magento\Framework\App\Action\HttpGetActionInterface;
use Magento\Framework\Controller\ResultInterface;
use Magento\Framework\Exception\LocalizedException;
/**
* Class AddToCart
* @package Magenest\BookingReservation\Controller\Product
*/
class AddToCart extends Action implements HttpGetActionInterface
{
/** @var \Magento\Checkout\Model\SessionFactory */
private $checkoutSession;
/** @var \Magento\Quote\Api\CartRepositoryInterface */
private $cartRepository;
/** @var \Magento\Catalog\Api\ProductRepositoryInterface */
private $productRepository;
/** @var \Magento\Framework\Serialize\Serializer\Json */
private $json;
/** @var \Magento\ConfigurableProduct\Model\Product\Type\Configurable */
private $configurableType;
/**
* AddToCart constructor.
* @param Context $context
* @param \Magento\Framework\Serialize\Serializer\Json $json
* @param \Magento\Checkout\Model\SessionFactory $checkoutSession
* @param \Magento\Quote\Api\CartRepositoryInterface $cartRepository
* @param \Magento\Catalog\Api\ProductRepositoryInterface $productRepository
* @param \Magento\ConfigurableProduct\Model\Product\Type\Configurable $configurableType
*/
public function __construct(
Context $context,
\Magento\Framework\Serialize\Serializer\Json $json,
\Magento\Checkout\Model\SessionFactory $checkoutSession,
\Magento\Quote\Api\CartRepositoryInterface $cartRepository,
\Magento\Catalog\Api\ProductRepositoryInterface $productRepository,
\Magento\ConfigurableProduct\Model\Product\Type\Configurable $configurableType
) {
$this->checkoutSession = $checkoutSession;
$this->cartRepository = $cartRepository;
$this->productRepository = $productRepository;
$this->json = $json;
$this->configurableType = $configurableType;
parent::__construct($context);
}
/**
* @return ResultInterface
* @throws LocalizedException
*/
public function execute()
{
$product = $this->productRepository->getById($this->getRequest()->getParam('id'));
$qty = $this->getRequest()->getParam('qty');
$session = $this->checkoutSession->create();
$quote = $session->getQuote();
$quote->addProduct($product, $qty);
$this->cartRepository->save($quote);
$session->replaceQuote($quote)->unsLastRealOrderId();
}
}
You can add products to the cart by specifying only their ID. If no quantity parameter is provided, the Quote Model will default to assuming a quantity of 1.
Add product to cart with additional options
The addProduct function supports both simple and advanced parameter formats, enabling you to include extra options and data with cart items as needed.
/**
* @throws LocalizedException
*/
public function addProductWithOptions()
{
$productSku = $this->getRequest()->getParam('sku');
$qty = $this->getRequest()->getParam('qty');
/**
* You can specify custom options for a product before adding it to cart
*/
$product = $this->productRepository->get($productSku);
$product->addCustomOption('additional_options', $this->json->serialize([
'custom_option_1' => [
'label' => __("Custom Option 1"),
'value' => 10
],
'custom_option_2' => [
'label' => __("Custom Option 2"),
'value' => 20
]
]));
/**
* The second parameter of addProduct function can either be an integer, or a Magento DataObject
* An integer will be interpreted as quantity added
* Using a DataObject will allow adding custom data to cart items; these data will be saved and can be retrieved as info_buyRequest of quote/order items
*/
$buyRequest = new \Magento\Framework\DataObject([
'qty' => $qty,
'related_product' => '',
'custom_option' => '?'
]);
$session = $this->checkoutSession->create();
$quote = $session->getQuote();
$quote->addProduct($product, $buyRequest);
$this->cartRepository->save($quote);
$session->replaceQuote($quote)->unsLastRealOrderId();
