Error: Request header field Content-Type is not allowed by Access-Control-Allow-Headers

At times, you get errors like this when you are trying to connect your localhost application to a remote server.

What you can do is to allow access control checks. Add the following code to your request header

header('Access-Control-Allow-Origin: *');
header("Access-Control-Allow-Headers: Origin, X-Requested-With, Content-Type, Accept");
header('Access-Control-Allow-Methods: GET, POST, PUT');

There you go!

Tell me in the comments if it works for you.
