Login.php

i stored the value

PHP Code:

$_SESSION['logvalue']="89"; 


Redirect.php

This is working on local Apache server. but not working on PLESK and 000Webhost..?

Code:

A PHP Error was encountered
Severity: Notice
Message: Undefined index: logvalue

Thanks..

Why you just not using :

Code:

$this->session->set_userdata()

 
Or for CI4

Code:

$session->set()

Before it you must call the session library.

Both ways work the same as i understand it, only difference between them being the CI session library has helper functions that makes things easier to do/work with.
 
In my case, I personally prefer pushing/deleting all my values to/from the $_SESSION variable (the way I learned way back in '03) and use the CI helper functions as needed.
