AJAX CORS error

[OBRDForum]

Hello,

I always get the CORS error when getting data from a php file using GET (ajax jquery), the php file and js file is stored locally. Does anyone have the same issue? On another php file it works with the same script just with another POST…

Error Message:

js:

    $.ajax({
        url: 'includes/functions/getLeaderboardData.php',
        type: 'GET',
        async: true,
        data: {getLeaderboard : 'true'},
        success: function (data) {
         output += data
        }
    });
php:
session_start();
include_once('../../includes/functions/db_credentials.php');
include_once('../../includes/functions/db_connection.php');

if(isset($_GET["getLeaderboard"]))
{
    $SQL = "SELECT idUsername, dtCredits FROM tbluser ORDER BY dtCredits DESC";
    $result = mysqli_query($dbc, $SQL);


    if(mysqli_errno($dbc))
    {
        die("wrong SQL: $SQL Error: " . mysqli_error($dbc));
    }
    for($i = 0; $i < mysqli_num_rows($result); $i++)
    {
        $row = mysqli_fetch_assoc($result);
        echo"<tr>
                     <td>{$row["idUsername"]}</td>
                     <td>{$row["dtCredits"]}</td>
            </tr>";
    }

}

You’ll have to move the file to a different folder. On free hosting, any file with a pathname containing includes returns a 403.
