header('Access-Control-Allow-Origin: http://localhost:8100'); header ("Access-Control-Expose-Headers: Content-Length, X-JSON"); header ("Access-Control-Allow-Methods: GET, POST, PATCH, PUT, DELETE, OPTIONS"); header ("Access-Control-Allow-Headers: Content-Type, Authorization, Accept, Accept-Language, X-Authorization"); header('Access-Control-Max-Age: 86400'); if ($_SERVER['REQUEST_METHOD'] === 'OPTIONS') { // The request is using the POST method header("HTTP/1.1 200 OK"); return; }

Access to XMLHttpRequest at 'http://localhost/MySQL_pracs/InsertUser.php' from origin 'http://localhost:4200' has been blocked by CORS policy: Request header field content-type is not allowed by Access-Control-Allow-Headers in preflight response.

//Access to XMLHttpRequest at 'http://localhost/[api path].php' from origin 'http://localhost:4200' has been blocked by CORS policy: Request header field content-type is not allowed by Access-Control-Allow-Headers in preflight response.

//The error is simply saying that "Content-Type" is missing from "Access-Control-Allow-Headers".

//Therefore we need to add "Content-Type" to "Access-Control-Allow-Headers".

<?php 
header('Access-Control-Allow-Headers: Content-Type');
-----
?>
