How To Display Stock Status for Product Variations

If you have products that tend to sell out, or that you typically sell in bulk, it might be beneficial to display the available product quantity. This can ensure your customers can order the quantity or volume they need.

Displaying your stock availability is as simple as adding a quick code snippet to your theme’s function.php.

<?php 
add_action( 'woocommerce_after_add_to_cart_form', 'dropdown_waitlist_label' );
function dropdown_waitlist_label() {
	echo "
		<script>
		jQuery(document).ready(function($) {
			var variation_data = $('form.variations_form').attr('data-product_variations');
			var variation_data = JSON.parse(variation_data);
			$('#pa_size > option').each(function() {
				for (var i = 0; i < variation_data.length; i++) {
					var variation = variation_data[i];
					if ($(this).val() == variation.attributes.attribute_pa_size) {
						if ( false == variation.is_in_stock ) {
							$(this).text( variation.attributes.attribute_pa_size + '\u00A0\u00A0\u00A0–\u00A0\u00A0\u00A0\u00A0Out of Stock');
						}
						if ( variation.min_qty == 1 && variation.max_qty == 1 ) {
							$(this).text( variation.attributes.attribute_pa_size + '\u00A0\u00A0\u00A0–\u00A0\u00A0\u00A0\u00A01 left in stock' );
						}
					}
				}
			});
		});
	</script>";
