仅当购物车中有来自特定类别的特定产品时才更改下单按钮文本

Question

我正在尝试更改结帐页面中的下单按钮文本的条件是，如果和只有当有一个产品在购物车中的“捐赠”类别。否则，希望将文本从“下订单”更改为“提交订单”。为此，我应用了以下代码

add_filter('woocommerce_order_button_text', 'subscriptions_custom_checkout_submit_button_text' );
function subscriptions_custom_checkout_submit_button_text( $order_button_text ) {

// set our flag to be false until we find a product in that category
$cat_check = false;

// check each cart item for our category
foreach ( WC()->cart->get_cart() as $cart_item_key => $cart_item ) {

    $product = $cart_item['data'];

    // replace 'donations' with your category's slug
    if ( has_term( 'donations', 'product_cat', $product->id ) && !has_term( 'dvds', 'product_cat', $product->id ) ){
        $cat_check = true;
        // break because we only need one "true" to matter here
        break;
    }
}



// if a product in the cart is in our category, do something
if ( $cat_check ) {


        $order_button_text =  __( 'Submit Donation', 'woocommerce-subscriptions'  );
    } else {
        // You can change it here for other products types in cart
        # $order_button_text =  __( 'Something here', 'woocommerce-subscriptions'  );
        $order_button_text =  __( 'Submit Order', 'woocommerce-subscriptions'  );
    }


    return $order_button_text;
}

它起作用了。但还有一个不同的问题..如果有来自其他类别和捐赠类别的产品。

我认为在if循环中需要应用AND条件。但是我不明白如何在if循环中应用和条件。

这对你来说应该是可行的：

add_filter('woocommerce_order_button_text', 'subscriptions_custom_checkout_submit_button_text' );
function subscriptions_custom_checkout_submit_button_text( $order_button_text ) {

    $donation = true;

    // check each cart item for our category
    foreach ( WC()->cart->get_cart() as $cart_item_key => $cart_item ) {

        $product = $cart_item['data'];

        if ( !has_term( 'donations', 'product_cat', $product->id ) ){
            $donation = false;
            break;
        }
    }


    return $donation ? 'Submit Donation' : 'Submit Order';
}
