我从这个网站上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;
}
这一功能可用于任何需要的地方:
if(woo_in_cart(123)) {
// Product is already in cart
}
问题是如何使用它检查多个产品,如:
if(woo_in_cart(123,124,125,126...)) {
// Product is already in cart
}
谢谢。

global$woocommerce
和$woocommerce-
下面是一个带有参数的自定义函数,该参数接受唯一整数产品ID或产品ID数组,并将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化:
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
}
这段代码可以正常工作。活动子主题的php文件(活动主题或任何插件文件)。
代码经过测试并正常工作。
用法:
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 '<p>There is "'. matched_cart_items($product_id) .'"matched items in cart</p><br>';
} else {
echo '<p>NO matched items in cart</p><br>';
}
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 '<p>There is "'. matched_cart_items($product_ids) .'"matched items in cart</p><br>';
} else {
echo '<p>NO matched items in cart</p><br>';
}
3) 对于3个或更多匹配购物车项目的产品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 '<p>There is "'. matched_cart_items($product_ids) .'"matched items in cart</p><br>';
} else {
echo '<p>NO matched items in cart</p><br>';
}
也许更简单,首先我们在购物车中获得产品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,如果您想检查一个产品,只需使用in_数组函数:
in_array(123, $product_ids);
对于不止一种产品:
array_intersect([123, 345, 567], $product_ids);
案例1:将数组作为参数传递。
function woo_in_cart($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;
}
如何调用函数
$is_incart=array(2,4,8,11);
print_r(woo_in_cart($is_incart));
情况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
}
}
