WWWForms keeps inserting blank values into mySQL

Hello everyone, I am trying to insert values from Unity to a PHP then to mySQL. I've tried inserting manually in a browser's address bar and it works fine, but when i use the WWW Form AddField, it connects successfully but inserts nothing, just blank values. I dont really know what's wrong.

Code (csharp):

1. public class addInfo : MonoBehaviour
2. {
3.     private string addInfoURL = "http://myurl.net/addInfo.php";
4.     private string username1 = "Albert";
5.     private string info1 = "this is my info";
6.    
7.     void Update ()
8.     {
9.         if(Input.GetKeyDown("h"))
10.         {
11.             WWWForm form = new WWWForm();
12.             form.AddField("username",username1);
13.             form.AddField("info",info1);
14.             WWW www = new WWW(addInfoURL, form);
15.             StartCoroutine(addInfoToDB(www));
16.         }
17.     }
18.    
19.     public IEnumerator addInfoToDB(WWW www)
20.     {
21.        
22.         yield return www;
23.         if (www.error == null)
24.         {
25.             Debug.Log("WWW Ok!: " + www.text);
26.         }
27.         else
28.         {
29.             Debug.Log("WWW Error: "+ www.error);
30.         }    
31.     }
32. }

Here's my php:

PHP:

<?php 
        $db = mysql_connect('host', 'username', 'pass') or die('Could not connect: ' . mysql_error()); 
        mysql_select_db('myDB') or die('Could not select database');

        $username = $_GET['username'];
        $info = $_GET['info'];
    
        $query = "insert into myDB values (NULL, '$username', '$info')"; 
        $result = mysql_query($query) or die('Query failed: ' . mysql_error()); 
?>

 

form data will not go through $_GET, that would be part of the url.
form data enter the php through $_POST

 

It worked! thank you very much.
