WooCommerce: Switch Image Background On Color Variation Selection

You could upload 10 images, one for each color of your variable product… or you could be slightly smarter and simply upload 1 “blank” image, and then when the user selects a color trigger a background color change!

Easier to code than to explain, so let’s take a look at the screenshot below (image must be a PNG with transparent background) and the PHP snippet. This could be a time-saver, enjoy!

The final output: background-color switches to “Red” once the “Red” variation is selected.
  • When yellow is selected
  • When no variation is selected

Where to add this snippet?

You can place PHP snippets at the bottom of your child theme functions.php file (delete "?>" if you have it there). CSS, on the other hand, goes in your child theme style.css file. Make sure you know what you are doing when editing such files - if you need more guidance, please take a look at my free video tutorial "Where to Place WooCommerce Customization?"

Does this snippet (still) work?

Please let me know in the comments if everything worked as expected. I would be happy to revise the snippet if you report otherwise (please provide screenshots). I have tested this code with Storefront theme, the WooCommerce version listed above and a WordPress-friendly hosting on PHP 7.3.

    Is it possible to do the same with the Variation gallery and change the image based on selected color while having 2 attributes with 2 variations like color + size. But use something similar to change images based on selected color and don’t wait to choose size?

      Hi Zimmer, thanks so much for your comment! Yes, this is definitely possible, but I’m afraid it’s custom work. If you’d like to get a quote, feel free to contact me here. Thanks a lot for your understanding!

    Hi Rodolfo,
    Code works great. Is there a way to make it autonomous so that we don’t have to code the available colors names and hex numbers? If you just get the selected color and adjust the background color acording to the color that is set on the selected attribute?

        Hi Rodolfo,
        I couldn’t get it working,
        I added a variable product with a color option. I can see the JS function is loading in my browser, but I am guessing the class or ID I am trying to reference is wrong. Something that I really havent got my head around fully yet.

          It could be you have a custom theme and something may need to be changed

            I got it sorted,

            I I am just using storefront with a pretty vanilla child theme.

            This is what I did:

            function bbloomer_switch_image_background_variable_colors() {
    
   wc_enqueue_js( "
    
      $('#color').change(function(){
	  	console.log('on change function')
         if('' != $('#color').val()) {
		 console.log('2 on change function')
            if($('#color').val() =='Red'){
			console.log('3 on change function')
               $('.woocommerce-product-gallery figure').css('background-color', 'red');
            } else if($('#color').val() =='Yellow'){
               $('.woocommerce-product-gallery figure').css('background-color', 'yellow');
            } 
         } else {
            $('.woocommerce-product-gallery figure').css('background-color', 'transparent');
         }
      });
    
   ");
    
}

            Thanks for your reply though.

            Cheers,

            Aaron.
