Update price on quantity change in Single Product Page – Woocommerce

Update price on quantity change in Single Product Page - Woocommerce


In a Woocommerce based online store wordpress, the price of a product may depend on the number of items a customer wants to purchase. For instance, a customer buying a single item may be charged at a different rate than someone buying multiple quantities of the same item.

To ensure that customers are billed correctly, it is necessary to update the price of the product on the single product page when a customer changes the quantity of the item they wish to purchase.

This functionality can be achieved through custom coding or by using a plugin specifically designed for this purpose in wordpress.

By updating the price on quantity change, customers can have a more accurate understanding of the cost of their purchase, making for a smoother shopping experience in wordpress site.

Method 1: Use the “Woo Product Quantity Range Price” Plugin

The “Woo Product Quantity Range Price” plugin is a sophisticated tool created for the popular e-commerce platform WooCommerce. This plugin enables online store owners to create quantity-based pricing for their items, providing price flexibility based on order numbers.

With this plugin, retailers may create pricing ranges for certain product quantities, giving consumers discounted rates or special incentives when they buy in bulk. By promoting bulk purchases and encouraging users to spend more, the plugin improves the shopping experience.

Method 2: Programmatically (Without Plugin)

Get the sub-total amount as customers increase the number of products on the single product page by adding the following codes to your function.php file.

add_action( 'woocommerce_after_add_to_cart_button', 'cxc_product_price_recalculate_call_back' );

function cxc_product_price_recalculate_call_back() {
	global $product;
	$price = $product->get_price();
	$currency = get_woocommerce_currency_symbol();
	<div class="cxc-sub-totals">
		<span class="cxc-sub-head">Sub Total:</span><span class="cxc-app-price"></span>
	<style type="text/css">
		.cxc-sub-totals { display: inline-block; border: 1px solid #000; padding: 14px; letter-spacing: 1px; }
		.cxc-sub-totals span.cxc-sub-head { margin-right: 5px; }
	<script type="text/javascript">
		jQuery( document ).ready( function() {
			setTimeout( function() {
			}, 100 );
			jQuery(document).on('change', 'input[name=quantity]', function() { 
				var cxc_qty = jQuery(this).val();
				var price = '<?php echo esc_js( $price ); ?>';
				var comman_price = '<?php echo esc_js( $price ); ?>';
				var cxc_currency = '<?php echo esc_js( $currency ); ?>';
				if( jQuery(this).closest( '.entry-summary' ).find('.cart').hasClass('variations_form') ){
					var variation_arr = jQuery.parseJSON(jQuery(this).closest( '.entry-summary' ).find('.cart').attr('data-product_variations'));
					var v_id = jQuery(this).closest( '.entry-summary' ).find('.cart .variation_id').val();	
					if( variation_arr !== undefined && variation_arr.length > 0 ){										
						jQuery(variation_arr).each(function (key, value) {
							if( v_id == value.variation_id ){
								price = value.display_price;
					if( v_id == '' || v_id == 0 || v_id === undefined ){
						price = comman_price;
				var cxc_price = ( price * cxc_qty ).toFixed(2);
				jQuery('.cxc-sub-totals > span.cxc-app-price').html( cxc_currency +''+cxc_price );
			jQuery(document).on('change', '.variations select', function() { 
				setTimeout( function() {
				}, 100 );				
		} );

  1. For variation product it’s not working, it’s picking up the first variation price always and makes the whole calculation with it.

    1. Thank you for bringing this to our attention. Our technical team worked diligently to address the problem, and we can now confirm that the correct prices for all product variations are being accurately displayed.

  2. I confirm that your code takes the lowest price of all variations of a product and multiplies that price with the quantity selected. So it doesn’t take the price of the selected variation as it should do. Maybe you could revise the code? Thx, Frank
