Ajax Powered Cart Items Count In WooCommerce

In WooCommerce, it's possible to use AJAX to update the number of items in a user's cart without requiring the page to be reloaded.

This can be useful for creating a more seamless shopping experience for your customers.

Here is an example of how you might use AJAX to update the cart item count in WooCommerce:

Add the following code to your theme's functions.php file.

This code should be added to the functions.php file of your active WordPress theme. It hooks into the woocommerce_add_to_cart_fragments filter and updates the #cart-count element with the number of items in the cart.

functions.php


_10add_filter( 'woocommerce_add_to_cart_fragments', 'ajax_add_to_cart_fragment' );
_10
_10function ajax_add_to_cart_fragment( $fragments ) {
_10	ob_start();
_10	$fragments['#cart-count'] = '<span id="cart-count">' . WC()->cart->get_cart_contents_count() . '</span>';
_10	ob_get_clean();
_10	return $fragments;
_10}

Add HTML element to WordPress theme.

Finally, in your WordPress theme's header.php you need to add HTML element to show the cart item count, that id should be cart-count for example, something like:


<span id="cart-count"></span>

When the visitor add an item to the cart, it triggers the added_to_cart event, which in turn triggers the AJAX request to update the cart item count. This allows the visitor to see the number of items in your cart.
