MySql and C# Communication

So I've looked at a few tutorials about communicating between MySql and C# scripts in Unity. When I run the Coroutine, the console tells me that the upload was completed successfully; however, when I run SELECT * FROM StudentUsers in my terminal, it says empty set. Now, I know I have an error with something somewhere but i don't know where... Thanks for the help.

My PHP Script:

Code (CSharp):

1. <?php
2.         $db = mysql_connect('localhost', '****', '****') or die('Could not connect: ' . mysql_error());
3.         mysql_select_db('MFHS_FanApp_db') or die('Could not select database');
4.         // Strings must be escaped to prevent SQL injection attack.
5.         $first_name = mysql_real_escape_string($_GET['first_name'], $db);
6.         $last_name = mysql_real_escape_string($_GET['last_name'], $db);
7.         $username = mysql_real_escape_string($_GET['username'], $db);
8.         $email = mysql_real_escape_string($_GET['email'], $db);
9.         $password = mysql_real_escape_string($_GET['password'], $db);
10.         $grad_year = mysql_real_escape_string($_GET['grad_year'], $db);
11.         $points = mysql_real_escape_string($_GET['points'], $db);
12.         $hash = $_GET['hash'];
13.         $secretKey="mySecretKey"; # Change this value to match the value stored in the client javascript below
14.  
15.         $real_hash = md5($first_name . $last_name . $username . $email . $password . $grad_year . $points . $secretKey);
16.         if($real_hash == $hash) {
17.             // Send variables for the MySQL database class.
18.             $query = "insert into StudentUsers values (NULL, '$first_name', '$last_name', '$username', '$email', '$password', '$grad_year', '$points');";
19.             $result = mysql_query($query) or die('Query failed: ' . mysql_error());
20.         }
21. ?>

My C# Method:

Code (CSharp):

1.     IEnumerator AddStudentUser(string first_name, string last_name, string username, string email, string password, int grad_year, int points)
2.     {
3.         print ("Begin AddStudentUser");
4.         //This connects to a server side php script that will add the name and score to a MySQL DB.
5.         // Supply it with a string representing the players name and the players score.
6.         string hash = Md5Sum(first_name + last_name + username + email + password + grad_year + points + secretKey);
7.        
8.         string post_url = URL_addStudentUser + "first_name=" + WWW.EscapeURL(first_name) + "&last_name=" + WWW.EscapeURL(last_name) + "&username=" + WWW.EscapeURL(username) +
9.                             "&email=" + WWW.EscapeURL(username) + "&password=" + WWW.EscapeURL(username) + "&grad_year" + grad_year + "&points=" + points + "&hash=" + hash;
10.         print (post_url);
11.         // Post the URL to the site and create a download object to get the result.
12.         WWW hs_post = new WWW(post_url);
13.         yield return hs_post; // Wait until the download is done
14.        
15.         if (hs_post.error != null)
16.         {
17.             print("There was an error posting the high score: " + hs_post.error);
18.         } else {
19.             print ("Successfully uploaded");
20.         }
21.     }

 

You're sending the email and the password as the username.

 

I feel stupid now haha. That would be why the hashes aren't matching. Thank you!
