I'm trying to get the country name and some other geolocalization details from the IP address and send them via CF7. I've using this code for some time now but I'm getting a warning of
undefined array key 'country'" city, IP, etc.
I'm trying to implement it in Wordpress and it does not work. If I use the same code in an isolated PHP file, it works perfectly. I'm a bit lost about what to do. I've tried to find documentation and find a solution by myself but I'm about to give up.
Here is my code:
$ip_address = getenv("HTTP_CLIENT_IP")?:
getenv("HTTP_X_FORWARDED_FOR")?:
getenv("HTTP_X_FORWARDED")?:
getenv("HTTP_FORWARDED_FOR")?:
getenv("HTTP_FORWARDED")?:
getenv("REMOTE_ADDR");
//CURL init. Matchs gotten IP with API values and retrives location value.
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, "http://ipinfo.io/".$ip_address."/");
curl_setopt($curl, CURLOPT_HEADER, 0);
curl_setopt($curl, CURLOPT_RETURNTRANSFER , true);
//json output.
$output = curl_exec($curl);
//CURL close.
curl_close($curl);
//"Country code to name" array.

P.D. I'VE READ ABOUT USING isset()... and some how it makes sense to me.
