I have problem with login. My $results = please login.

Answer 1

First check what $result["users_login"] contains.. You are getting the please login because you don't have the session data.

I am not sure about your approach, but don't mix php session and Ionic, You can create a kind of API to check user credentials from your ionic App, or else handle it in the ionic app.
Session normally used in websites to pass data through out the page, not for API calls. Think of scenario 10 users access your app simultaneously, How you going to use the Session to verify them?

My advise is, instead of using PHP sessions, you can handle your sessions inside your app using the session storage
Read this. There are plenty of plugin available. OR you can create your as shown here
Good Luck!!
