在 WooCommerce 中为 WC_Order 添加自定义函数 [英] Add custom function to WC_Order in WooCommerce

问题描述

我刚刚为 WooCommerce 创建了一个自定义插件，所以我可以添加一种新的手动付款方式，到目前为止我已经可以运行它了.但我现在面临的问题是我得到了一个 0 值.

I just created a custom plugin for WooCommerce, so I can add a new manual payment method, so far I already can get it running. But the problem I face right now is I get a 0 value.

我创建了一个扩展WC_Order()的类，这是代码

I create a class that extend WC_Order(), here is the code

class WC_Order_Extender extends WC_Order {

    public function __construct( $order_id ) {

        parent::__construct( $order_id );

        $this->data['price_in_btc'] = 0.0;

        print_r($this->data);
    }

    public function get_price_in_btc() {

        return $this->get_prop( 'price_in_btc' );
    }

    public function set_price_in_btc( $value ) {

        $this->set_prop( 'price_in_btc', wc_format_decimal( $value, 7 ) );
    }
}

这里是调用函​​数的时间

and here is when the function is called

public function process_payment( $order_id ) {

    //$order = new WC_Order( $order_id );
    $order_extended = new WC_Order_Extender( $order_id );

    // get_price_in_btc() always return 0 in thankyou.php page
    $order_extended->set_price_in_btc( $this->get_bitcoin_rate( $order_extended->get_total() ) );

    // Mark as On-Hold (We're waiting for the payment)
    $order_extended->update_status( 'on-hold', __( 'Awaiting for manual BTC payment ', 'wc-manual-btc-gateway' ) );

    // Reduce item stocks
    wc_reduce_stock_levels( $order_id );

    // Clean up the cart
    WC()->cart->empty_cart();

    // Return thank you redirect
    return array(
        'result'    => 'success',
        'redirect'  => $this->get_return_url( $order_extended )
    );
}

这是在thankyou.php页面中调用price_in_btc值的代码

Here is the code to call price_in_btc value in thankyou.php page

$extended_order = new WC_Order_Extender( $order->get_id() );

echo $extended_order->get_price_in_btc(); // Always return 0

一开始我以为是因为返回0.00*****币，所以四舍五入到0，所以我以为是小数点的问题，所以我设置prop时添加wc_format_decimal，但返回0，即使实际返回比特币价格为0.0004***.

at first I thought because it return 0.00***** coin, so it rounded to 0, so I thought it's a problem with the decimal, so I add wc_format_decimal when set the prop, but it's still return as 0, even the actual return bitcoin price is 0.0004***.

请帮忙，我在代码中犯的错误在哪里?

Please help, where is the mistake I made in my code?

存储在扩展$order

证明price_in_btc()函数返回一个值console.log()

这是代码

public function get_bitcoin_rate( $total_price ) {

    $cUrl = curl_init();

    curl_setopt_array( $cUrl, array(
        CURLOPT_URL => 'https://api.coindesk.com/v1/bpi/currentprice/IDR.json',
        CURLOPT_RETURNTRANSFER => true,
        CURLOPT_TIMEOUT => 30,
        CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
        CURLOPT_CUSTOMREQUEST => "GET",
        CURLOPT_HTTPHEADER => array(
            "cache-control: no-cache"    
        )
    ) );

    $data = json_decode( curl_exec( $cUrl ), true );

    $err = curl_error( $cUrl );

    curl_close( $cUrl );

    echo "<script>console.log( '" . wc_format_decimal( $total_price / $data['bpi']['IDR']['rate_float'], 7 ) . "' );</script>";

    return $total_price / $data['bpi']['IDR']['rate_float'];
}

这里是 wc_format_decimal()

我在set_price_in_btc()下面添加了$order_extended->save();:

$order_extended->set_price_in_btc( $this->get_bitcoin_rate( $order_extended->get_total() ) );
$order_extended->save();

但它仍然返回一个 0 值.请帮助我不知道该怎么办.

But it's still return a 0 value. Please help I don't know what to do.

推荐答案

在谷歌上徘徊，寻找答案后，我终于有点放弃我目前的编码，删除订单扩展器 然后创建一个非常非常简单的代码，我不知道这样行不行.

After wandering around across the google, and finding for some answer, finally I kinda give up with my curent coding, delete the order extender and then create a really-really simple codes, that I don't know is this OK or not.

对于和我有同样问题并且没有找到答案的任何人，请使用以下代码:

For anyone that having some troubles the same with me and didn't found the answer, use this code:

add_action( 'woocommerce_checkout_create_order', 'wc_add_custom_meta_order', 20, 2 );

function wc_add_custom_meta_order( $order, $data ) {

    $order->update_meta_data( '_price_in_btc', $data );
}

用于插入新的自定义元数据

For inserting the new custom meta data

$price_in_btc = number_format( $this->get_bitcoin_rate( $order->get_total() ), 5 );

before_checkout_create_order( $order, $price_in_btc );

这很好地解决了我的问题，尽管这样做有点愚蠢，而且在thankyou.php页面中，我只需要使用get_post_meta($order->get_id(),'_price_in_btc', 真)

this solves my problem very well even though it's kinda the stupid way to do it, and in the thankyou.php page I just need to call the meta directly using get_post_meta( $order->get_id(), '_price_in_btc', true )

希望这个回答对你有用！干杯!:D
