### Error Message

Access to XMLHttpRequest at ‘[http://niceday.free.nf/api.php](http://niceday.free.nf/api.php)’ from origin ‘[http://localhost:3000](http://localhost:3000)’ has been blocked by CORS policy: Response to preflight request doesn’t pass access control check: No ‘Access-Control-Allow-Origin’ header is present on the requested resource.

```
if($_SERVER["REQUEST_METHOD"] == "POST" ){
    $data = json_decode(file_get_contents("php://input"), true);
    include '../config/db.php';
    
    $username = $data["username"];
    
    $query = $conn->prepare("SELECT * FROM `user` WHERE `username` = ?");
    $query->bindParam(1, $username, PDO::PARAM_STR);
    if($query->execute()){
        $user = $query->fetch(PDO::FETCH_ASSOC);
        if($user){

        }else{
            echo json_encode(array("message" => "Wrong Username", "status" => false));    
        }
    }else{
        echo json_encode(array("message" => "Wrong Username", "status" => false));    
    }

To give a little bit of context to @anon90933456’s post: our hosting does not support or allow CORS. We provide hosting for websites, not API’s.

If you are building a frontend Javascript application with a PHP backend, you can host it on our hosting, as long as you’re hosting them on the same hostname. And for development, you should run both the Javascript application and the PHP backend locally.
