I have a MySQL database and I want to insert a data into it by using php. Here are my php codes:

<?php 
    $db = mysql_connect('host', 'user', 'pass') or die('Could not connect: ' . mysql_error()); 
    mysql_select_db('dbname') or die('Could not select database');
    $ThreeNumber = $_GET["tn"];
    $Number = $_GET["n"];
    $Counter = $_GET["c"];
    $UserId = $_GET["u"];
    $hash = $_GET['hash']; 
    $secretKey="mySecretKey";
    $real_hash = md5( $ThreeNumber . $Number . $Counter . $UserId . $secretKey); 
    if($real_hash == $hash) { 
        $query ="INSERT INTO chapter (threeNum, num , count,user)  VALUES ('$ThreeNumber','$Number','$Counter','$UserId')"; 
        $result = mysql_query($query) or die('Query failed: ' . mysql_error()); 
    } 
    else
    {
        die('HASH ERROR'); 
    }
 ?>

Here are my C# codes:

  public void startPostScores()
    {
        StartCoroutine(SendScore(_three, _num, _count, _user));
    }

IEnumerator SendScore(int three, int num, int count, string user)
    {
        string hash = Md5Sum(three.ToString() + num.ToString() + count.ToString() + user + secretKey);
        string post_url = "http://mywebsite.com/postScore.php?" + "tn=" + three +
                                                                     "&n=" + num +
                                                                     "&c=" + count +
                                                                     "&u=" + WWW.EscapeURL(user) +
                                                                     "&hash=" + hash;
        Debug.Log(post_url);
        WWW www = new WWW(post_url);
        yield return www;
        if (!string.IsNullOrEmpty(www.error))
        {
            Debug.Log("There was an error posting to the SQL: " + www.error);
        }
    }

When my post_url is **localhost **, it works, the data is inserted, but when it is another domain name, it doesn’t work. In addition, when I paste the full URL into a browser it works, too.

SOLVED!!

My code was like that:

 public void startPostScores()
     {
         StartCoroutine(SendScore(_three, _num, _count, _user));
         SceneManager.LoadScene(0);
     }

The problem is this line:

 SceneManager.LoadScene(0);

When I Send a request by WWW, the scene changes immidiately so time doesn’t enough for request. I removed the line and it works.

Thanks.
