过滤商品中的货币，并将其从美元转换为印度卢比 - Filter currency in wocoommerce and convert it from usd to inr for ccavenue

我在我的wordpress网站上使用ccavenue支付网关。
插件网址 https://wordpress.org/plugins/ccavenue-payment-gateway-woocommerce/
但是我有一个问题，我的基础货币是印度卢比，而ccavenue只接受印度卢比付款，所以当用户将货币转换为美元时，ccavenue将40美元作为40印度卢比。
我想在将货币发送到ccavenue页面之前转换货币。
相同的代码片段是。

 public function generate_ccavenue_form($order_id){
        global $woocommerce;
        $order = new WC_Order($order_id);
        $redirect_url = ($this -> redirect_page_id=="" || $this -> redirect_page_id==0)?get_site_url() . "/":get_permalink($this -> redirect_page_id);
      //For wooCoomerce 2.0
        $redirect_url = add_query_arg( 'wc-api', get_class( $this ), $redirect_url );
        $order_id = $order_id.'_'.date("ymds");
        $checksum = $this -> getCheckSum($this -> merchant_id, $order->order_total, $order_id, $redirect_url, $this -> working_key);

        $ccavenue_args = array(
            'Merchant_Id' => $this -> merchant_id,
            'Amount' => $order->order_total,
            'Order_Id' => $order_id,
            'Redirect_Url' => $redirect_url,
            'Checksum' => $checksum,
            'currency_code' => get_woocommerce_currency(),
            'billing_cust_name' => $order -> billing_first_name .' '. $order -> billing_last_name,
            'billing_cust_address' => $order -> billing_address_1,
            'billing_cust_country' => $order -> billing_country,
            'billing_cust_state' => $order -> billing_state,
            'billing_cust_city' => $order -> billing_city,
            'billing_zip' => $order -> shipping_postcode,
            'billing_cust_tel' => $order -> billing_phone,
            'billing_cust_email' => $order -> billing_email,
            'delivery_cust_name' => $order -> shipping_first_name .' '. $order -> shipping_last_name,
            'delivery_cust_address' => $order -> shipping_address_1,
            'delivery_cust_country' => $order -> shipping_country,
            'delivery_cust_state' => $order -> shipping_state,
            'delivery_cust_tel' => $order -> shipping_phone,
            'delivery_cust_notes' => '',
            'Merchant_Param' => '',
            'billing_zip_code' => $order -> billing_postcode,
            'delivery_cust_city' => $order -> shipping_city,
            'delivery_zip_code' => $order -> shipping_postcode
            );
        $ccavenue_args_array = array();
        foreach($ccavenue_args as $key => $value){
            $ccavenue_args_array[] = "<input type='hidden' name='$key' value='$value'/>";
        }

我想我必须在函数.php中为此添加一个过滤器钩子。但是我无法为此制作和添加过滤器。

您可以使用 Google API 进行货币转换。

您必须

在woocommcerce中放置一些自定义函数来实时转换您的货币，因为CCavenue不支持INR，因此您必须首先转换为美元，然后将此可变金额发送到CCavenue表单。

将以下代码添加到函数中.php并执行所需的适当操作。

<?php
$from_currency    = 'USD';
$to_currency    = 'INR';
$amount            = 1;
$results = converCurrency($from_currency,$to_currency,$amount);
$regularExpression     = '#'<span class=bld'>(.+?)'<'/span'>#s';
preg_match($regularExpression, $results, $finalData);
echo $finalData[0];
function converCurrency($from,$to,$amount){
    $url = "http://www.google.com/finance/converter?a=$amount&from=$from&to=$to"; 
    $request = curl_init(); 
    $timeOut = 0; 
    curl_setopt ($request, CURLOPT_URL, $url); 
    curl_setopt ($request, CURLOPT_RETURNTRANSFER, 1); 
    curl_setopt ($request, CURLOPT_USERAGENT,"Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1)"); 
    curl_setopt ($request, CURLOPT_CONNECTTIMEOUT, $timeOut); 
    $response = curl_exec($request); 
    curl_close($request); 
    return $response;
} 
?>
