使用woocommerce中的ajax删除购物车中的产品

Question

我想使用ajax删除woocommerce购物车中的产品而不点击链接.

如果您遇到过这种功能,请帮助我们.

add_action( 'wp_footer', 'add_js_to_wp_wcommerce');

function add_js_to_wp_wcommerce(){ ?>
    <script type="text/javascript">
    jQuery('.remove-product').click(function(){
        var product_id = jQuery(this).attr("data-product_id");
        jQuery.ajax({
            type: 'POST',
            dataType: 'json',
            url: "/wp-admin/admin-ajax.php",
            data: { action: "product_remove", 
                    product_id: product_id
            },success: function(data){
                console.log(data);
            }
        });
        return false;
    });
    </script>
<?php }

add_action( 'wp_ajax_product_remove', 'product_remove' );
add_action( 'wp_ajax_nopriv_product_remove', 'product_remove' );
function product_remove() {
    global $wpdb, $woocommerce;
    session_start();
    foreach ($woocommerce->cart->get_cart() as $cart_item_key => $cart_item){
        if($cart_item['product_id'] == $_POST['product_id'] ){
            // Remove product in the cart using  cart_item_key.
            $woocommerce->cart->get_remove_url($cart_item_key);
        }
    }
    print_r($woocommerce->cart->get_cart());
    //echo json_encode(array('status' => 0));
    exit();
}

Answer 1

你可以使用WC_Cart set_quantity方法

并在你的PHP中这样做:

$cart = WC()->instance()->cart;
$id = $_POST['product_id'];
$cart_id = $cart->generate_cart_id($id);
$cart_item_id = $cart->find_product_in_cart($cart_id);

if($cart_item_id){
   $cart->set_quantity($cart_item_id,0);
}

Answer 2

用这个 :

$cart = $woocommerce->cart;

foreach ($woocommerce->cart->get_cart() as $cart_item_key => $cart_item){
    if($cart_item['product_id'] == $_POST['product_id'] ){
        // Remove product in the cart using  cart_item_key.
        $cart->remove_cart_item($cart_item_key);
    }
}
