在WooCommerce购物车中获取购物车商品的商品ID

Question

$cart_item = $woocommerce->cart->get_cart(); 

我有上面的代码.

如果我在cart_item上运行print_r,我会得到一个多维数组:

Array(    [a6292668b36ef412fa3c4102d1311a62] => Array        (            [product_id] => 6803

我如何才获得product_id？

我试过$ test = $cart_item['data'];

print_r($test);

没工作.

Answer 1

要获取product IDforeach循环中的每个购物车项目(对于简单的产品):

foreach( WC()->cart->get_cart() as $cart_item ){
    $product_id = $cart_item['product_id'];
}

如果它是一个可变产品,那么得到variation ID:

foreach( WC()->cart->get_cart() as $cart_item ){
    $variation_id = $cart_item['variation_id'];
}

或两种情况( Woocommerce 3+中$cart_item['data'] 的 WC_Product Object):

foreach( WC()->cart->get_cart() as $cart_item ){
    // compatibility with WC +3
    if( version_compare( WC_VERSION, '3.0', '<' ) ){
        $product_id = $cart_item['data']->id; // Before version 3.0
    } else {
        $product_id = $cart_item['data']->get_id(); // For version 3 or more
    }
}

更新:在循环外使用产品ID

1)打破循环(只是为了得到购物车的第一个商品ID(产品ID)):

foreach( WC()->cart->get_cart() as $cart_item ){
    $product_id = $cart_item['product_id'];
    break;
}

您可以直接使用$product_id购物车中第一个项目的变量.

2)使用产品ID数组(购物车中的每个项目一个).

$products_ids_array = array();

foreach( WC()->cart->get_cart() as $cart_item ){
    $products_ids_array[] = $cart_item['product_id'];
}

• 要获得第一个商品ID: $products_ids_array[0];
• 要获得第二项产品ID:$products_ids_array[1]; 等...

要检查购物车项目中的产品类别或产品标签,请使用WordPress has_term():

foreach( WC()->cart->get_cart() as $cart_item ){
    // For product categories (term IDs, term slugs or term names)
    if( has_term( array('clothing','music'), 'product_cat', $cart_item['product_id'] ) ) {
        // DO SOMETHING
    }

    // For product Tags (term IDs, term slugs or term names)
    if( has_term( array('clothing','music'), 'product_tag', $cart_item['product_id'] ) ) {
        // DO SOMETHING ELSE
    }
}

$cart_item['product_id']当购物车项目是产品变体时,我们总是使用,因为我们得到了父变量产品.

产品类型不会将任何自定义分类作为产品类别和产品标记处理
