woocommerce how to get $cart_item_key for a single product
提问by Sarah McLachlane
I'm implementing a Remove Item button next to the add to cart button however I have a problem getting the variable $cart_item_key for a single product. I have the global variables $woocommerce and $product but the only way $cart_item_key is used is a foreach which doesn't help me at all as I need my code to be added in add-to-cart.php.
我在添加到购物车按钮旁边实现了一个删除项目按钮，但是我在获取单个产品的变量 $cart_item_key 时遇到了问题。我有全局变量 $woocommerce 和 $product，但使用 $cart_item_key 的唯一方法是 foreach，它根本没有帮助我，因为我需要将代码添加到 add-to-cart.php 中。

You have to set the remove link for each product within loop like this,
您必须像这样在循环中为每个产品设置删除链接，
foreach ( $woocommerce->cart->get_cart() as $cart_item_key => $cart_item ) {
echo $cart_item_key;
if($cart_item['product_id'] == $your_product_id_to_remove ){
//remove single product
}
}
In any situation you have cart item listing; from that you have to remove, so foreachwill work with your requirement.
在任何情况下，您都有购物车项目列表；您必须从中删除，以便foreach满足您的要求。
Hope its helps..

这段代码对我有用。感谢 Jobin Jose ( https://stackoverflow.com/users/1258004/jobin-jose) 的解决方案！
foreach ( $woocommerce->cart->get_cart() as $cart_item_key => $cart_item ) {
if ($cart_item['product_id'] == $product->id ) {
echo apply_filters( 'woocommerce_cart_item_remove_link', sprintf('<a href="%s" class="remove" title="%s">×</a>', esc_url( $woocommerce->cart->get_remove_url( $cart_item_key) ), __( 'Remove this item', 'woocommerce' ) ), $cart_item_key );
}
