Codeigniter session-> userdata（）返回相反的......！

I'm trying to fix an issue with permissions in my app, I have a session->userdata('usrclass') set when login with different account class.

I have an ADMIN user who has a usrclass of ADMIN and I need to show some content based on that.

BUT when I do this:

<?= ($this->session->userdata('usrclass') == "ADMIN") ? 'yes' : 'no'; ?>

It outputs "no"... While it should output "yes". So I tried reading into the sessiondata with this code:

<?= echo $this->session->userdata('usrclass') ?>

This outputs the word ADMIN... This is a weird behavior, I've tried using ===, I've tried to figure out other stuff but couldn't.

What could it be?

I'm going to attach some pics of this:

may be there are some extra whitespace(s) in your session data value, try:

<?php
    $sess_data = $this->session->userdata('usrclass');
    $sess_data = trim($sess_data);
    //and echo
    echo ($sess_data == "ADMIN") ? "si" : "no";
?>

You could try making sure it's a string coming back from the session. ((string) $this->session->userdata('usrclass') == "ADMIN") ? 'yes' : 'no';

Maybe a long shot but could the first userdata('usrclass') be wiping the value. Try removing the test code. echo $this->session->userdata('usrclass')
