In WooCommerce, the popular e-commerce platform for WordPress, the single product page plays a crucial role in showcasing your products to potential customers. One important aspect of the single product page is the product image, which can significantly impact the overall appearance and user experience.
By default, WooCommerce provides predefined image sizes for product images, such as thumbnail, medium, large, and full. However, you might have specific requirements for the size of your product images that aren’t covered by these defaults. In such cases, you can use coding to get a custom single product image size in the WooCommerce single product page. Let’s explore the steps involved in achieving this.
Step 1: Determine the Desired Image Size
Before diving into the coding aspect, you need to determine the custom image size you want to implement on your single product page. Consider factors such as the dimensions, aspect ratio, and how the image will fit within the overall product page layout. Once you have a clear idea of the image size you want, proceed to the next step.
Step 2: Modify the Functions.php File
The functions.php file of your active theme contains the necessary code for adding custom functionality to your WooCommerce store. To get started, access the file using a code editor or through the WordPress dashboard (Appearance → Theme Editor → functions.php). Within the functions.php file, you’ll need to add a new image size using the add_image_size() function provided by WordPress. This function takes parameters such as a unique name for the image size, the desired width, height, and whether to crop the image to exact dimensions. Here’s an example code snippet to add a custom image size named ‘custom-single-product’ with a width of 800 pixels and a height of 600 pixels:function custom_single_product_image_size() {
add_image_size( ‘custom-single-product’, 800, 600, true );
}
add_action( ‘after_setup_theme’, ‘custom_single_product_image_size’ );
Step 3: Regenerate Thumbnails (Optional)
If you have already uploaded product images to your WooCommerce store before adding the custom image size, you may need to regenerate the thumbnails to ensure that the new size is generated for those images. You can use plugins like “Regenerate Thumbnails” or “Force Regenerate Thumbnails” to accomplish this task easily.
Step 4: Display the Custom Image Size on the Single Product Page
With the custom image size added, the final step is to display it on the WooCommerce single product page. To achieve this, you’ll need to locate the relevant code in your theme’s template files responsible for displaying the product image. Typically, the single product page template file is called ‘single-product.php’ or ‘content-single-product.php’. Look for the code that outputs the product image, which is usually enclosed within a loop. Within that code block, find the functionwoocommerce_get_product_thumbnail(). By default, this function uses the ‘woocommerce_thumbnail’ image size. To make it use your custom image size, replace 'woocommerce_thumbnail' with 'custom-single-product' in the function call. Here’s an example: <?php echo woocommerce_get_product_thumbnail( ‘custom-single-product’ ); ?>
Save the changes to the template file and view a single product page to see your custom image size in action.
Congratulations! You have successfully implemented a custom single product image size in your WooCommerce single product page using coding.
Remember to consider the impact of larger image sizes on page load times and optimize your images accordingly. With custom image sizes, you can tailor your product images to match your store’s design and improve the overall
