[Dev] Convert prices of woocommerce to btc/sats

100 sats \ 5 comments \ @gzoo 10 Oct 2022

hi guys! how are you? I have a question for worpress developers. What would be the easiest way to convert the currency I have set in my woocommerce shop to btc? Right now I have my products with prices set in € but I would like to show the equivalent in btc/sats. I was thinking in a snippet in function.php or something. do any of you already have a solution for this?

Im using btcpayserver connected to my node, but i dont find any setting to do that

I am grateful for any help or guidance you can give me.

It's been many moons since I wrote some PHP, but let's give this a go:

1function fiat_to_btc($price, $currency_code) {
2    $price_oracle_url = "https://blockchain.info/tobtc?currency=$currency_code&value=$price";
3        
4    $ch = curl_init($price_oracle_url);
5    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
6    curl_setopt($ch, CURLOPT_HEADER, 0);
7    $data = curl_exec($ch);
8    curl_close($ch);
9    
10    return $data;
11}

14print(fiat_to_btc(99.99, "EUR"));

Thanks man it really helps!! I have adapted the function to work in the front end of wordpress, just add this to the function.php file of your theme.

In case anyone wants to use/understand it: What the function does is to take the regular price of the woocommerce product, store it in the variable $product_p and then pass the price acquired through the get of $price_oracle_url. after that the price of the product converted to btc with an updated exchange rate appears in the front end through add_action and inside a html span tag with the css class btc-price, so you can play with a custom css.

1function woocommerce_regular_price_tobtc(){
2	$all_meta_data = get_post_meta(get_the_ID());
3	$product_p=$all_meta_data['_regular_price'][0];
4	$price_oracle_url = "https://blockchain.info/tobtc?currency=eur&value=$product_p";
5	$ch = curl_init($price_oracle_url);
6	curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
7    curl_setopt($ch, CURLOPT_HEADER, 0);
8    $data = curl_exec($ch);
9	curl_close($ch);
10    print "<span class='btc-price'>{$data}₿</span>";
