将免费产品添加到woocommerce购物车

Question

我有一个片段，根据所选的变体向woocommerce购物车添加了免费产品。 代码工作正常，但是问题是当我重新加载页面时，数量增加了。 我需要知道如何检查购物车的更新时间，或要防止几次添加免费产品的方法。

这是片段。

  if ( sizeof( WC()->cart->get_cart() ) > 0 ) { foreach(WC()->cart->get_cart() as $cart_item ) { global $product,$post; $added=false; $i=1; $item_name = $cart_item['data']->get_title(); $quantity = $cart_item['quantity']; $price = $cart_item['data']->get_price(); $variation_id = $cart_item['variation_id']; $variation = wc_get_product($variation_id); $terms = get_the_terms( $cart_item['product_id'], 'product_cat' ); foreach ($terms as $term) { $product_cat_id = $term->term_id; if($product_cat_id==65){ if(strpos($variation->get_formatted_name(),"Dinner for 2",0) !== false ){ WC()->cart->add_to_cart(104748); $added=true; }else if(strpos($variation->get_formatted_name(),"Dinner for 4",0) !== false ){ WC()->cart->add_to_cart(104748,2); $added=true; }else if(strpos($variation->get_formatted_name(),"Dinner for 6",0) !== false ){ WC()->cart->add_to_cart(104748,3); $added=true; }else if(strpos($variation->get_formatted_name(),"Dinner for 8",0) !== false ){ WC()->cart->add_to_cart(104748,4); $added=true; }else if(strpos($variation->get_formatted_name(),"Dinner for 10",0) !== false ){ WC()->cart->add_to_cart(104748,5); $added=true; }else if(strpos($variation->get_formatted_name(),"Dinner for 12",0) !== false ){ WC()->cart->add_to_cart(104748,6); $added=true; } } } } } 

感谢任何帮助谢谢

您需要每次检查您的产品是否已经在购物车中。 如果不是，则仅将产品添加到购物车，否则您需要跳过。

请使用此功能将您的产品添加到购物车-

function add_in_cart($product_id) { 
    global $woocommerce;
    var $isProductExist = false;

    foreach( $woocommerce->cart->get_cart() as $key => $val ) { 
        $_product = $val['data']; 
        if($product_id == $_product->id ) { 
        $isProductExist =true;
        break;
    } 
    if($isProductExist=false)
        $woocommerce->cart->add_to_cart($product_id);
}
