php - Unable to connect to my web API from Java Bukkit Plugin -

i have made web api want bukkit plugin connect to. plugin sends post httpurlconnection file 'registerplugin.php' in website. code file is:

<?php     require("api.php");      registerplugin($_post["name"], $_post["ip"], $_post["port"], $_post["online"], $_post["uuid"]); 

?>

the code registerplugins method in file 'api.php' is:

    function registerplugin($name, $ip, $port, $playersonline, $uuid) {         $sql = "insert api_activeplugins (plugin_name, plugin_ip, plugin_port, players_online, plugin_uuid) values ('$name', '$ip', '$port', '$playersonline', '$uuid')";         get_mysql()->query($sql);     } 

and code in bukkit plugin is:

private void connect(string api, string args) {     try {         byte[] data = args.getbytes(charset.forname("utf-8"));         int datalength = args.length();         plugin.getlogger().info(args);         string request = "http://www.theperkyturkey.tk/admin/api/" + api + ".php";         url url = new url(request);         httpurlconnection connection = (httpurlconnection) url.openconnection();         connection.setdoinput(true);         connection.setdooutput(true);         connection.setrequestmethod("post");         connection.setrequestproperty("content-type", "application/x-www-form-urlencoded");         connection.setrequestproperty("charset", "utf-8");         connection.setrequestproperty("content-length", string.valueof(datalength));          dataoutputstream out = new dataoutputstream(connection.getoutputstream());         out.write(data);         out.flush();         out.close();     } catch(exception e) {         e.printstacktrace();     } } 

which called in onenable() method by:

    string name = plugin.getdescription().getname();     string ip = plugin.getserver().getip();     string port = string.valueof(plugin.getserver().getport());     string online = string.valueof(plugin.getserver().getonlineplayers().size());     string uuid = "test";     connect("registerplugin", "name=" + name + "&ip=" + ip + "&port=" + port + "&online=" + online + "&uuid=" + uuid); 

it not error database because able use method registerplugin() inside 'api.php' file without errors. error lies in connection between plugin , web api. in advance help! (by way being hosted hostinger)
