php WooCommerce：将产品添加到购物车并覆盖价格？

WooCommerce: Add product to cart with price override?

提问by dcolumbus

$replace_order = new WC_Cart();
$replace_order->empty_cart( true );
$replace_order->add_to_cart( "256", "1");

The above code add product 256to the Cart 1time. But the issue I'm having is that I want to be able to completely override the product price... as far as I can tell, the only thing I can do it apply a coupon to the Cart.

上面的代码将产品添加256到购物车1时间。但我遇到的问题是我希望能够完全覆盖产品价格......据我所知，我唯一能做的就是将优惠券应用到购物车。

Is there a way to completely override the price to something totally custom?

有没有办法将价格完全覆盖为完全定制的东西？

Here is the code for overriding price of product in cart

这是覆盖购物车中产品价格的代码

add_action( 'woocommerce_before_calculate_totals', 'add_custom_price' );

function add_custom_price( $cart_object ) {
    $custom_price = 10; // This will be your custome price  
    foreach ( $cart_object->cart_contents as $key => $value ) {
        $value['data']->price = $custom_price;
        // for WooCommerce version 3+ use: 
        // $value['data']->set_price($custom_price);
    }
}

Hope it will be useful...

希望它会很有用...

You need to introduce an ifstatement for checking product id, in above code:

你需要if在上面的代码中引入一个检查产品id的语句：

add_action( 'woocommerce_before_calculate_totals', 'add_custom_price' );

function add_custom_price( $cart_object ) {
    $custom_price = 10; // This will be your custome price  
    $target_product_id = 598;
    foreach ( $cart_object->cart_contents as $value ) {
        if ( $value['product_id'] == $target_product_id ) {
            $value['data']->price = $custom_price;
        }
        /*
        // If your target product is a variation
        if ( $value['variation_id'] == $target_product_id ) {
            $value['data']->price = $custom_price;
        }
        */
    }
}

Add this code anywhere and make sure that this code is always executable.

在任何地方添加此代码并确保此代码始终可执行。

After adding this code, when you'll call:

添加此代码后，何时调用：

global $woocommerce; 
$woocommerce->cart->add_to_cart(598);

Only this product will be added with overridden price, other products added to cart will be ignored for overriding prices.

只有此产品会添加覆盖价格，其他添加到购物车的产品将被忽略覆盖价格。

Hope this will be helpful.

希望这会有所帮助。

    foreach ( WC()->cart->get_cart() as $cart_item_key => $cart_item ) {
        $cart_item['data']->set_price($custom_price);

For eveeryone that got here from Google. The above is now deprecated as i found out updating to WooCommerce 3.0.1.

对于从 Google 来到这里的每个人。当我发现更新到 WooCommerce 3.0.1 时，上述内容现已弃用。

Instead of the above you now need to use set_priceinstead of price

您现在需要使用set_price代替上面的代替price

Here is an example:

下面是一个例子：

add_action( 'woocommerce_before_calculate_totals', 'add_custom_price' );
function add_custom_price( $cart_object ) {
    $custom_price = 10; // This will be your custome price  
    foreach ( $cart_object->cart_contents as $key => $value ) {
        $value['data']->set_price = $custom_price;
    }
}

I hope this helps people in the future :)

我希望这对未来的人们有所帮助:)

To make it dynamic ( override price for each item in cart separately ), you need to save the override product price in session with cart item key as session key using woocommerce_add_to_carthook.

为了使其动态化（分别覆盖购物车中每件商品的价格），您需要使用woocommerce_add_to_cart钩子将购物车项目键作为会话键保存在会话中的覆盖产品价格。

by using these session values you can calculate correct Cart Total and make the altered price appear in the Order Item as well

通过使用这些会话值，您可以计算正确的购物车总数并使更改后的价格也出现在订单项中

With WooCommerce 2.5 I found this to be a 2-part process. The first step is to change the run-time display of pricing when added to the cart via the woocommerce_add_cart_item filter. The second part is to set the persistent session data which is read during checkout via the woocommerce_get_cart_item_from_session filter. This seems to be faster than hooking the calculate totals filters (such as woocommerce_before_calculate_totals) as they are run very frequently in WooCommerce.

在 WooCommerce 2.5 中，我发现这是一个由两部分组成的过程。第一步是在通过 woocommerce_add_cart_item 过滤器添加到购物车时更改定价的运行时显示。第二部分是通过 woocommerce_get_cart_item_from_session 过滤器设置在结账期间读取的持久会话数据。这似乎比挂钩计算总计过滤器（例如 woocommerce_before_calculate_totals）更快，因为它们在 WooCommerce 中运行非常频繁。

This is how i did it, first i add my custom price to cart_item_data witch can save custom data to cart items, then i use woocommerce_before_calculate_totals, loop the cart and add the previously added price.

我就是这样做的，首先我将自定义价格添加到 cart_item_data 女巫可以将自定义数据保存到购物车项目，然后我使用 woocommerce_before_calculate_totals，循环购物车并添加之前添加的价格。

function add_donation_to_cart() { 

    $cart_item_data = array('price' => $_REQUEST['donate_amount']);
    $woocommerce->cart->add_to_cart( 5395, 1, '', array(), $cart_item_data);
}


add_action( 'woocommerce_before_calculate_totals', 'add_custom_price' );

function add_custom_price( $cart ) {
    foreach ( $cart->cart_contents as $key => $value ) {
        $value['data']->price = $value['price'];
    }
}

You can use the following

您可以使用以下

add_filter( 'woocommerce_cart_item_price', 'kd_custom_price_message' );

function kd_custom_price_message( $price ) {

        $textafter = ' USD'; 
        return $price . $textafter;
}
