How to Add Facebook Share Option in Magento 2

Magento 2 is a powerful eCommerce platform, but it does not come with built-in social media share buttons like Facebook out of the box. Adding a Facebook share option to your Magento 2 store can significantly enhance your product visibility and increase engagement. By using PHP and a simple HTML anchor tag, you can integrate a Facebook share button that allows users to share product details directly to their Facebook feed. In this guide, we will walk through the steps required to add a functional Facebook share option to your Magento 2 store.

Step 1: Fetch Product Data in Magento 2

To begin, you need to fetch essential product details such as the product name and URL. This will allow the Facebook share button to include accurate and dynamic information when sharing a product. In Magento 2, you can use the Object Manager to retrieve product data. The code snippet below shows how to fetch the necessary product details:

Place this code inside a relevant block or template file (e.g., catalog_product_view.xml or a .phtml file) where you want to display the share button:

<?php
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$productCollection = $objectManager->create('Magento\Catalog\Model\ResourceModel\Product\CollectionFactory');
$collection = $productCollection->create()
    ->addAttributeToSelect('*')
    ->load();

foreach ($collection as $_product){
    $proName = $_product->getName();
    $proUrl = $_product->getProductUrl();
}
?>

$proName → This variable stores the product name
$proUrl → This variable stores the product URL
These variables are used to dynamically generate the share link for Facebook
It’s especially useful for adding the Facebook share button on custom product listing pages
For better practice, it’s recommended to use dependency injection instead of ObjectManager

Step 2: Add Facebook Share Button

Now that you have retrieved the necessary product data, the next step is to add the Facebook share button to your template. This button will allow users to share the product on their Facebook profile. The code below shows how you can create the share button using a simple HTML anchor tag:

<a href="https://www.facebook.com/sharer/sharer.php?u=<?php echo urlencode($proUrl); ?>&t=<?php echo urlencode($proName); ?>"
   onclick='javascript:window.open(this.href,"","width=640,height=480,left=0,top=0,location=no,status=yes,scrollbars=yes,resizable=yes");return false'
   title="Share on Facebook">
   <span class="fab fa-facebook"></span> Share on Facebook
</a>

URL Encoding: The urlencode() function ensures that the product URL and name are properly encoded for the Facebook share link.
Popup Window: The JavaScript window.open() function creates a small popup window where the user can confirm sharing the product on Facebook.
Cross-Platform: This button works on both desktop and mobile browsers, ensuring a consistent user experience across devices.
FontAwesome Icons: The button uses the FontAwesome icon for Facebook, which can be customized with CSS for better visual appeal.

Step 3: Customize the Facebook Share Button

The default share button can be customized in several ways to better fit the design and functionality of your website. You can change the look of the button by replacing the FontAwesome icon with a custom image, adjusting the button’s size and color using CSS, or adding hover effects to make the button more interactive.

For example, if you want to use a custom image instead of the FontAwesome icon, you can modify the code as follows:

<a href="https://www.facebook.com/sharer/sharer.php?u=<?php echo urlencode($proUrl); ?>&t=<?php echo urlencode($proName); ?>"
   onclick='javascript:window.open(this.href,"","width=640,height=480,left=0,top=0,location=no,status=yes,scrollbars=yes,resizable=yes");return false'
   title="Share on Facebook">
   <img src="path/to/facebook-icon.png" alt="Share on Facebook" />
</a>

Custom Image: You can replace the <span> tag with an <img> tag to display a custom Facebook share icon.
CSS Styling: Use CSS to adjust the size, position, and hover effects of the button to make it align with your site’s overall design.
Interaction: Add hover or click animations to make the button more engaging for users, increasing the chances of interaction.

Comparative Analysis: Native vs Custom Social Share

While Magento 2 does not natively support a Facebook share button, implementing one manually offers several advantages over using a third-party extension. Let’s compare the native implementation versus using an extension:

Customization: A custom implementation gives you full control over the design, behavior, and placement of the share button.
Performance: Custom code is lightweight and does not require loading additional scripts or plugins, ensuring a faster page load time.
Cost: Adding a Facebook share button manually is free, unlike third-party extensions that may come with a cost, especially for premium features.

Best Practices for Social Sharing Integration

When integrating social sharing options like Facebook, it’s important to follow best practices to ensure functionality and user experience are optimal. Here are some key best practices to consider:

Ensure Mobile Responsiveness: Social sharing buttons should be easily accessible and function well on mobile devices. Ensure that the button is displayed correctly on smaller screens.
Consider Multiple Platforms: While Facebook is a popular platform, consider adding other social media sharing options, such as Twitter, LinkedIn, or WhatsApp, to increase your reach.
Use Clear Call-to-Action: Your share button should have a clear and compelling call-to-action, such as “Share this product” or “Let your friends know,” to encourage users to interact with it.

Conclusion

Adding a Facebook share button to your Magento 2 store is a straightforward process that can yield significant benefits in terms of product visibility and engagement. By manually implementing a Facebook share option, you gain full control over the design and functionality of the button while keeping your site lightweight and fast. Additionally, following best practices ensures that your social share buttons are responsive, accessible, and optimized for a seamless user experience. Overall, the integration of social media sharing options is an essential step towards enhancing your store’s online presence and improving customer engagement.
