Automatically Update Cart when quantity changed in WooCommerce


Today’s blog will allow you to have your cart totals automatically update when you modify the amount field without having to click the update button on the cart page.

Remove the WooCommerce Update Cart Button

add_action( 'wp_head', 'cxc_cart_refresh_update_hide_button' );
function cxc_cart_refresh_update_hide_button() { 
		.woocommerce button[name="update_cart"],
		.woocommerce input[name="update_cart"] { display: none; }

Automatically WooCommerce Cart when Quantity Changes

Now that the button is hidden, all we need to do is “click” it with JQuery and let WooCommerce handle the rest.

add_action( 'wp_footer', 'cxc_cart_refresh_update_qty' ); 
function cxc_cart_refresh_update_qty() { 
	if ( is_cart() || ( is_cart() && is_checkout() ) ) {
			jQuery( function( $ ) {
				let timeout;
				jQuery('.woocommerce').on('change', 'input.qty', function(){
					if ( timeout !== undefined ) {
						clearTimeout( timeout );
					timeout = setTimeout(function() {
						jQuery("[name='update_cart']").trigger("click"); // trigger cart update
					}, 1000 ); // 1 second delay, half a second (500) seems comfortable too
			} );
