Question

中找到了这个很棒的片段

以下是检查购物车中是否存在特定产品的功能：

        function woo_in_cart($product_id) {
        global $woocommerce;         
        foreach($woocommerce->cart->get_cart() as $key => $val ) {
            $_product = $val['data'];

            if($product_id == $_product->id ) {
                return true;
            }
        }         
        return false;
        }

这可以在任何需要的地方使用：

      if(woo_in_cart(123)) {
     // Product is already in cart
     }

问题是如何用它来检查这样的多个产品：

      if(woo_in_cart(123,124,125,126...)) {
     // Product is already in cart
     }

感谢。

Answer 1

global $woocommerce 和 $woocommerce->cart 过时，只需替换 WC()->cart

这是一个自定义函数，其参数接受唯一的整数产品ID或产品ID数组，并返回购物车中匹配的ID数。

代码处理任何产品类型，包括可变产品和产品变体：

function matched_cart_items( $search_products ) { $count = 0; // Initializing if ( ! WC()->cart->is_empty() ) { // Loop though cart items foreach(WC()->cart->get_cart() as $cart_item ) { // Handling also variable products and their products variations $cart_item_ids = array($cart_item['product_id'], $cart_item['variation_id']); // Handle a simple product Id (int or string) or an array of product Ids if( ( is_array($search_products) && array_intersect($search_products, cart_item_ids) ) || ( !is_array($search_products) && in_array($search_products, $cart_item_ids) $count++; // incrementing items count } } return $count; // returning matched items count }

此代码位于您的活动子主题（活动主题或任何插件文件）的function.php文件中。

代码经过测试并有效。

<强> USAGE：

1）对于唯一的产品ID（整数）：

$product_id = 102; // Usage as a condition in an if statement if( 0 < matched_cart_items($product_id) ){ echo 'There is "'. matched_cart_items($product_id) .'"matched items in cart '; } else { echo 'NO matched items in cart '; }

2）对于产品ID数组：

$product_ids = array(102,107,118); // Usage as a condition in an if statement if( 0 < matched_cart_items($product_ids) ){ echo 'There is "'. matched_cart_items($product_ids) .'"matched items in cart '; } else { echo 'NO matched items in cart '; }

3）对于3个或更多匹配购物车商品的产品ID数组，例如：

$product_ids = array(102, 107, 118, 124, 137); // Usage as a condition in an if statement (for 3 matched items or more) if( 3 <= matched_cart_items($product_ids) ){ echo 'There is "'. matched_cart_items($product_ids) .'"matched items in cart '; } else { echo 'NO matched items in cart '; }

Answer 2

案例1：传递数组作为参数。

 function woo_in_cart($arr_product_id) {
        global $woocommerce;         
        $cartarray=array();

        foreach($woocommerce->cart->get_cart() as $key => $val ) {
            $_product = $val['data'];
            array_push($cartarray,$_product->id);
        }         
        $result = !empty(array_intersect($cartarray,$arr_product_id));
        return $result;

        }

如何调用功能

$is_incart=array(2,4,8,11);
print_r(woo_in_cart($is_incart));

案例2：使用您运行的代码。

$is_in_product_cart=array(123,124,125,126,..);

foreach($is_in_product_cart as $is_in_cart ) 
    if(woo_in_cart($is_in_cart))
    {
        // Product is already in cart
    }
}

Answer 3

也许更简单一些，首先我们在购物车中获取产品ID：

$product_ids = array_merge(
  wp_list_pluck(WC()->cart->get_cart_contents(), 'variation_id'),
  wp_list_pluck(WC()->cart->get_cart_contents(), 'product_id')
);

现在，如果您要检查一种产品，只需使用in_array函数：

in_array(123, $product_ids);

以及不止一种产品：

array_intersect([123, 345, 567], $product_ids);

Answer 4

woo_in_cart函数出错。这是正确的：

 function woo_in_cart($arr_product_id) {
    global $woocommerce;
    $cartarray=array();

    foreach($woocommerce->cart->get_cart() as $key => $val ) {
       $_product = $val['product_id'];
       array_push($cartarray,$_product);
    }

    if (!empty($cartarray)) {
       $result = array_intersect($cartarray,$arr_product_id);
    }

    if (!empty($result)) {
       return true;
    } else {
       return false;
    };

}

这是一个用法示例：

//Set IDs Array variable

$my_products_ids_array = array(22,23,465);
if (woo_in_cart($my_products_ids_array)) {
  echo 'ohh yeah there some of that products in!';
}else {
  echo 'no matching products :(';
}
