如果其他购物车商品属于特定类别，请将产品添加到woocommerce购物车

如果购物车中的任何商品来自特定类别，我需要能够有条件地将产品的 one 添加到WooCommerce订单/购物车 . 这是我尝试的代码，但它锁定了结帐和购物车页面，返回没有woocommerce信息，或之后的任何内容（没有页脚，没有其他页面元素等等......直到前面的WooCommerce数据 - 结束后，有一个很大的空白） . 如果有人能指出我正确的方向，那将是非常感谢！

这是我在functions.php文件中的内容：

/**
 * Checks the cart to verify whether or not a product from a Category is in the cart
 * @param $category Accepts the Product Category Name, ID, Slug or array of them
 * @return bool
 */
function qualifies_basedon_product_category( $category ) {
    foreach( WC()->cart->cart_contents as $key => $product_in_cart ) {
        if( has_term( $category, 'fee', get_id_from_product( $product_in_cart, false ) ) ) {
            return true;
        }
    }
    // Return false in case anything fails
    return false;
}

/**
 * Adds a specific product to the cart
 * @param $product_id Product to be added to the cart
 */
function add_incentive_to_cart( $product_id ) {
    // Check the cart for this product
    $cart_id = WC()->cart->generate_cart_id( $product_id );
    $prod_in_cart = WC()->cart->find_product_in_cart( $cart_id );
    // Add the product only if it's not in the cart already
    if( ! $prod_in_cart ) {
        WC()->cart->add_to_cart( $product_id );
    }
}



add_action( 'woocommerce_check_cart_items', 'qualifies_for_incentive' );
function qualifies_for_incentive() {
    // Incentive product
    $incentive_product_id = 506;

    if( qualifies_basedon_product_category( 'fee' ) ) {
        add_incentive_to_cart( $incentive_product_id );
    } 
}

    你可以调查以下代码 -

    add_action('woocommerce_add_to_cart', 'my_woocommerce_add_to_cart', 10, 6);

function my_woocommerce_add_to_cart( $cart_item_key, $product_id, $quantity, $variation_id, $variation, $cart_item_data ){
    $incentive_product_id = 506;
    $category = 'fee';
    $taxonomy = 'fee';

    if( has_term( $category, $taxonomy, $product_id ) ){    
        $cart_id = WC()->cart->generate_cart_id( $incentive_product_id );
        $prod_in_cart = WC()->cart->find_product_in_cart( $cart_id );

        // Add the product only if it's not in the cart already
        if( ! $prod_in_cart ) {
            WC()->cart->add_to_cart( $incentive_product_id );
        }
    }
}

    希望这可能对你有所帮助 .

    把它放在你的functions.php中：

    function df_add_ticket_surcharge( $cart_object ) {
global $woocommerce;
$specialfeecat = 20763; // category id you want to check for
$spfee = 0.00; // initialize special fee
$spfeeperprod = 0.00; //special fee per product
$found = $false; //required to make the code later only add the item once, also stop loops.
$product_id = 38607; //product id of the one you want to add

foreach ( $cart_object->cart_contents as $key => $value ) {

    $proid = $value['product_id']; //get the product id from cart
    $quantiy = $value['quantity']; //get quantity from cart
    $itmprice = $value['data']->price; //get product price

//check if the desired product is already in cart.
if ( sizeof( $woocommerce->cart->get_cart() ) > 0 ) {
        foreach ( $woocommerce->cart->get_cart() as $cart_item_key => $values ) {
            $_product = $values['data'];
            if ( $_product->id == $product_id )
                $found = true;
        }
    }

//check for the category and add desired product
    $terms = get_the_terms( $proid, 'product_cat' ); //get taxonomy of the products
    if ( $terms && ! is_wp_error( $terms ) ) :
        foreach ( $terms as $term ) {
            $catid = $term->term_id;
            if($specialfeecat == $catid && ! $found) {
                WC()->cart->add_to_cart( 38607 );
            }
        }
    endif;  
   }
}
add_action( 'woocommerce_cart_calculate_fees', 'df_add_ticket_surcharge' );

    我修改了现有代码中的代码，这就是为什么spfee和spfeeperprod仍在那里，但你并不真正需要它们，这就是为什么我把它们设置为0.我注意到让这段代码工作的缺点是这部分：

    if ( sizeof( $woocommerce->cart->get_cart() ) > 0 ) {
        foreach ( $woocommerce->cart->get_cart() as $cart_item_key => $values ) {
            $_product = $values['data'];
            if ( $_product->id == $product_id )
                $found = true;
        }
    }

    这将检查您要添加的项目的产品ID，该产品ID指定为“$ product_id” . 希望这会有所帮助（我昨天与它斗争了很多，但今天早上终于有了突破！）
