结帐前更改购物车项目订阅属性值 [英] Change cart items subscription properties values before checkout

问题描述

这可能是一个菜鸟问题，所以提前致歉.

This may be a noob question so apologies in advance.

我有可变的订阅产品，其价格随订阅时间的长短而异.我也有一个简单的订阅，其subscription_length =0.当购物车同时包含两种类型时，Woocommerce订阅会创建两个订阅.

I have variable subscription products whose price varies by subscription length. I also have simple subscriptions that have a subscription_length = 0. When the cart contains both types, Woocommerce subscriptions creates two subscriptions.

我正在尝试修改购物车中所有商品的subscription_length元数据以匹配购物车中最长的长度，因此只能创建一个订阅.

I am trying to modify the subscription_length metadata of all the items in the cart to match the longest length in the cart so only one subscription will be created.

我似乎找不到正确的方法来更新购物车.这可能只是愚蠢的人类PHP技巧.

I just can't seem to find right way to update the cart. It might just be stupid human PHP tricks.

这是该语句的最新变体，目前无法正常运行:

This is the latest variation of the statement that is not working right now:

$cart[$item_key]['data']->subscription_length = $maxlength;

我已经尝试了数十种或更多种主题，以更新$ cart数据.有些失败，有些成功，但是$ cart中的数据没有改变.

I've tried a dozen or more variations on the theme to update the $cart data. some failed and some succeeded but the data in $cart did not change.

function csi_align_subscription_length() {
    $maxlength = 0;
    $cart = WC()->cart->get_cart();

    //find the longest length
    foreach ( $cart as $item_key => $item ){
        if ( WC_Subscriptions_Product::is_subscription( $item['data'] ) ) {
            $length = WC_Subscriptions_Product::get_length( $item['data'] );
            $maxlength = ($length > $maxlength) ?  $length : $maxlength ;   //get the longest length
        }
    }   

    //set all subscription lengths to the longest lengths
    foreach ( $cart as $item_key => $item ){
        if ( WC_Subscriptions_Product::is_subscription( $item['data'] ) ) {
            echo '<pre>';
            echo "cart-item before: ". var_dump($cart[$item_key]);
            $cart[$item_key]['data']->subscription_length = $maxlength;
            echo "cart-item after:  ".var_dump($cart[$item_key]);
            echo '</pre>';
        }
    }   
    WC()->cart->set_cart_contents($cart);
}
add_filter( 'woocommerce_subscription_cart_before_grouping', 'csi_align_subscription_length', 10, 1 );

我只需要在购物车中获得订阅即可与一个普通组对齐，因此每次结帐时我只有1个订单和1个订阅.如果我在切线上迷路了，我愿意接受另一种方法.

I just need to get the subscriptions in the cart to align to a common group so I only have 1 order and 1 subscription per checkout. I am open to a different approach if I've gotten lost off on a tangent.

推荐答案

最终解决了该问题.没有用于"subscription_length"的设置器.不得不使用update_meta_data方法.元密钥为"_subscription_length".以下代码有效.

Finally resolved the issue. No setter for 'subscription_length'. Had to use update_meta_data method. The meta key is '_subscription_length'. the following code works.

function csi_align_subscription_length( $cart ) {
    if ( ( is_admin() && ! defined( 'DOING_AJAX' ) )  )
        return;

    if ( did_action( 'woocommerce_before_calculate_totals' ) >= 2 )
        return;

    $maxlength = (float) 0;

    // Find the longest subscription length
    foreach ( $cart->get_cart() as $cart_item ){
        if ( is_a( $cart_item['data'], 'WC_Product_Subscription' ) || is_a( $cart_item['data'], 'WC_Product_Subscription_Variation' ) ) {
            $length = (float) WC_Subscriptions_Product::get_length( $cart_item['data'] );
            $maxlength = ($length > $maxlength) ?  $length : $maxlength ;   //get the longest length
        }
    } 

    // set the subscription length for everything in the cart
    foreach ( $cart->get_cart() as $item_key => $cart_item ){
        if ( is_a( $cart_item['data'], 'WC_Product_Subscription' ) || is_a( $cart_item['data'], 'WC_Product_Subscription_Variation' )) {
            $cart_item['data']->update_meta_data( '_subscription_length', $maxlength );
        }
    }
}

add_action( 'woocommerce_before_calculate_totals', 'csi_align_subscription_length', 5, 1 );
