php，檢查購物車是否包含要求 - 添加優惠券

Question

我試圖讓php檢查購物車在應用免費產品和優惠券之前是否有數組中指定的2個項目。我列出的這個具體例子是檢查價格是否超過一定數量。我試過這個，因爲我無法讓這兩個項目工作。

function bbloomer_add_gift_if_sku_added_cart($passed, $product_id, $quantity) { 
global $woocommerce; 


$skuswithgift = array('SMWB-M23','001-SLW'); 


$giftsku = 'comb'; 

$coupon_code = 'combfree'; 

$product = wc_get_product($product_id); 

if ($product->get_sku() && in_array($product->get_sku(), $skuswithgift) && $woocommerce->cart->total > 26.00) { 
    WC()->cart->add_to_cart(wc_get_product_id_by_sku($giftsku)); 
    wc_add_notice(__('Hey there! As promised, you recieved a free comb with the purchase of two towels and we added it to your cart for you!', 'woocommerce'), 'success'); 
    $woocommerce->cart->add_discount($coupon_code); 
} 

else { 
    WC()->cart->remove_cart_item(wc_get_product_id_by_sku($giftsku)); 
    $woocommerce->cart->remove_coupon($coupon_code); 
} 

return $passed; 
} 

add_filter('woocommerce_add_to_cart_validation', 'bbloomer_add_gift_if_sku_added_cart', 10, 3);

嘗試這樣做，它不工作

function bbloomer_add_gift_if_sku_added_cart($passed, $product_id, $quantity) { 
global $woocommerce; 

$skuswithgift = array('SMWB-M23','001-SLW'); 

$giftsku = 'comb'; 

$coupon_code = 'combfree'; 

$product = wc_get_product($product_id); 

$total_towels = 0; 

// Determine how many towels there are 
// Loop through every cart item 
foreach ($woocommerce->cart->get_cart() as $cart_item) { 

    $product = $cart_item['data']; 
    //$product = $cart_item; 

    // Is it in Gift SKUs 
    $is_towel = in_array($product->get_sku(), $skuswithgift); 
    if($is_towel){ 
    // Add this quantity to the total towels 
    $total_towels += intval($cart_item['quantity']); 
    } 

} 


// Apply Discount 
if ($total_towels <= 2) { 
    WC()->cart->add_to_cart(wc_get_product_id_by_sku($giftsku)); 
    wc_add_notice(__('Hey there! As promised, you recieved a free comb with the purchase of two towels and we added it to your cart for you!', 'woocommerce'), 'success'); 
    $woocommerce->cart->add_discount($coupon_code); 
} 

else { 
    WC()->cart->remove_cart_item(wc_get_product_id_by_sku($giftsku)); 
    $woocommerce->cart->remove_coupon($coupon_code); 
} 

return $passed; 
} 

add_filter('woocommerce_add_to_cart_validation', 'bbloomer_add_gift_if_sku_added_cart', 10, 3);

試試下面的代碼

add_action('woocommerce_add_to_cart_redirect','customeApplyCode'); 
function customeApplyCode() 
{ 
    global $woocommerce;  
    $items = $woocommerce->cart->get_cart(); 
    $productSku = array(); 
    foreach($items as $item => $values) { 
     // Retrieve WC_Product object from the product-id: 
     $product = wc_get_product($values['product_id'] ); 
     // Get SKU from the WC_Product object: 
     $productSku[] = $product->get_sku(); 
    } 
    $skuswithgift = array('SMWB-M23','001-SLW'); 
    $result=array_intersect($skuswithgift,$productSku); 
    if(count($result)>0) 
    { 
     //product id of free product 
     $product_id = 1312; 
     $woocommerce->cart->add_to_cart($product_id); 
     add_filter('woocommerce_product_needs_shipping', 'hide_shipping_when_free_is_available', 10, 2);  
    } 

} 
function hide_shipping_when_free_is_available($rates, $package) { 
    return false; 
}
