Hi everyone, Maya here!
Today, I’ll share a custom code snippet that allows you to create a sleek and responsive product carousel without relying on a third-party plugin.
Let’s dive into it!

Woocommerce Product Carousel Slider Without Plugin

Product carousels are a fantastic way to:

  • Showcase featured products: Highlight your best-selling or latest items.
  • Promote special offers: Draw attention to discounted products.
  • Increase product visibility: Give more products a chance to shine.
  • Enhance user engagement: Carousel rotation keeps visitors interested.

Step 1: Add the Code to your functions.php file

Access your WordPress dashboard and navigate to Appearance > Theme File Editor. Locate the functions.php file of your active theme and paste the following code snippet:

You must create a child theme before making any changes to functions.php file. Otherwise, the applied changes will be lost after each update.

Step 2: Use the Shortcode in your pages

The above code registers a shortcode in WordPress, which you can use to add a product carousel to your site. Here’s how it works:

[woo-slider sale_badge="on" rating="on" card="4" description="off" check_stock="off" on_sale="off" cats="" type="" auto_paly="off" theme="1"]

You can insert this shortcode anywhere on a page or post to display the carousel. Here’s a breakdown of the attributes you can use with the shortcode:

  • card="4" sets the number of cards (products) displayed in each slide to 4.
  • num="10" limits the number of loaded products to 10 (default value).
  • sale_badge="off" hides the sale badge on discounted products.
  • rating="off" hides the product rating.
  • description="off" hides the short product description (default).
  • check_stock="on" excludes out-of-stock products from the carousel.
  • on_sale="on" displays only discounted products.
  • cats="10,15," displays products from specific categories (separate IDs with commas).
  • type="featured" displays only featured products.
  • type="bestselling" displays best-selling products first.

For example, this shortcode displays a carousel showcasing discounted products from 12 and 17 categories:

[woo-slider num="15" on_sale="on" cats="12,17" ]

Product Carousel PLUS+

The Plus version of this code has all the features of the standard version, along with two new exciting features:

  • If you set the auto_play attribute to “on” the carousel will automatically start playing.
  • In addition to the standard theme, you will also have access to a new theme, which can be activated by setting the theme attribute to “2”

If you want to enjoy the benefits of the Plus version, you need to update your code with the following snippet.

Why Go Plugin-Free?

While plugins offer convenience, they can introduce drawbacks:

  • Security: Plugins can be vulnerable to attacks, putting your site at risk. Custom code minimizes this risk.
  • Performance: Plugins can slow down your site, negatively impacting user experience and SEO. Custom code keeps your site lean and fast.
  • Compatibility: Plugins can conflict with each other or with your theme, causing issues. Custom code avoids these problems.
  • Control: Custom code gives you full control over the carousel’s functionality and appearance, allowing you to tailor it to your needs.

Got Questions?

Here are some additional points you might be curious about:

Can I use this code if I’m not familiar with web development?

Yes! This guide provides a simple, step-by-step process that anyone can follow, regardless of their technical knowledge. Just copy the provided code snippets and follow the instructions.

Can I use this code to create multiple carousels on the same page?

Yes, you can use the shortcode multiple times with different attributes to create distinct carousels on the same page.

Is this carousel mobile-responsive?

Absolutely! The carousel is built with responsive design principles, ensuring it adapts seamlessly to different screen sizes and devices.

How can I customize the appearance of the carousel further?

If you’re comfortable with CSS, you can add custom styles to your theme’s stylesheet to modify the carousel’s appearance. Use the browser’s developer tools to identify the carousel’s elements and apply your custom styles.
