PHP：pop显示应用服务器超时

Question

I have a PHP app written in codeIgniter. Getting some complaints from clients about the app timing out. Their session times out after two hours of inactivity and they can't seem to remember that.

Is there a way and if so, how, to show a pop up message when a users session has timed out?

Thank you in advance.

Answer 1

PHP cannot display a pop up by itself, but you could probably have a JavaScript query the session status and display a pop up when the session is expired, or even better, count the time since the session opened and let the user know in advance that his session is about to time out

If you want change the duration of the session, see this line in your config.php

$config['sess_expiration']      = 7200;

7200 is 120 minutes * 60 seconds. If you change it to 0, the session will not expire.

To add a warning, the very simplest method would probably to add a JavaScript similar to

setTimeout(function(){alert("Your session will expire in 5 minutes")},6900000); // 6900 seconds (115 minutes) * 1000 milliseconds
