encoded issue

[thegbomb]

I am passing an array:
$postParams = array(
'order_id' => $cart_order_id,
'price_amount' => $grandTotal,
'price_currency' => 'XBT',
'receive_currency' => 'XBT',
Etc
Which seems to be passed into the curl_exec as:
“order_id=180605-102147-3094&price_amount=0.002831367&price_currency=XBT&receive_currency=XBT&”

(http_build_query($params) produces the above string)

It looks like there is encoding is happening somewhere because when I look in https://coingate.com/account/apps/api-requests

I can see “{"order_id":"180605-102147-3094","amp;price_amount":"0.002831367","amp;price_currency":"XBT","amp;receive_currency":"XBT","amp;” etc

Obviously somewhere the & is encoded to & but then not decoded again.

Any clues to solving this?

This seems to solve the issue

After some pondering, I suspect this could also work:

-            curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query($params));
+            curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query($params, '', '&'));
