Astra』s Header Footer Builder comes with the WooCommerce Cart element that allows you to add the mini-cart to your header. By default, the mini-cart displays a number of items added to the cart together with the icon.
The mini-cart will show the number 「0」 until the first product is added to the cart.
In case you would like to hide this number, you can do it by adding a custom code (filter). Adding the filter will hide the number of products while the mini-cart is empty.
To do this, you would need to add the following filter to the functions.php file of your Child Theme:
add_filter('astra_woo_header_cart_total', 'remove_cart_count');
function remove_cart_count( $default){
if(0 == WC()->cart->get_cart_contents_count()){
return false;
}else{
return $default;
}
}
If you don』t have your Child Theme installed, please check this article on how to do it.
