i have a problem! I have create a app with Ionic that connects to a external database (mysql) through a file php.
I have inserted the following lines of code in the file:
header("Access-Control-Allow-Headers: Access-Control-, Origin, X-Requested-With, Content-Type, Accept”);
but I keep having the following error
“[Error] Origin http://localhost:8103 is not allowed by Access-Control-Allow-Origin.
[Error] Failed to load resource: Origin http://localhost:8103 is not allowed by Access-Control-Allow-Origin. (retrive_data.php, line 0)
[Error] XMLHttpRequest cannot load /app_es/retrive_data.php due to access control checks.”
Can someone help me, thanks!
