Flashdata don't show up

Hello everyone,

I am having issues with flashdata. For some reason any of them won't show up. 

I am setting it like this:

Code:

// Controller
$this->session->set_flashdata('user_registered', 'You Registered Successfully!');
redirect('/'); // redirects to the index page (login page)

Code:

// View
<?php if($msg=$this->session->flashdata('user_registered')): ?>
  <?php '<p class="alert alert-danger">'.$msg.'</p>' ?>
<?php endif; ?>

I have tried 'keep_flashdata' but doesn't seem to work.
These are the configurations:

$config['sess_driver'] = 'files';
$config['sess_cookie_name'] = 'ci_session';
$config['sess_expiration'] = 7200;
$config['sess_save_path'] = NULL;
   // $config['sess_save_path'] = sys_get_temp_dir();
$config['sess_match_ip'] = FALSE;
$config['sess_time_to_update'] = 300;
$config['sess_regenerate_destroy'] = FALSE;

$autoload['libraries'] = array('database', 'email', 'form_validation', 'session');

Any help is very appreciated. 
Thank You!

You need to set your session path directory, this is how I do it.

Create a new directory under your ./application directory called writable.

Then set your session save path to this.

PHP Code:

$config['sess_save_path'] = APPPATH.'writable'; 


This works fine for me.

What did you Try? What did you Get? What did you Expect?

The sessions  are being saved to the folder but flashdata are still not showing up. 

You can set flash session message using this line
$this->session->set_flashdata('success_message', 'Csv Data Imported Succesfully');

And you can Retrieve Flash session message using this line

<div class="alert alert-success successMessage">' . $this->session->flashdata('success_message') . '</div>

and $this->load->library('session');


Also updated these lines in cofig.php file
$config['sess_driver'] = 'database';
$config['sess_cookie_name'] = 'ci_session';
$config['sess_expiration'] = 7200;
$config['sess_save_path'] = 'ci_sessions';
$config['sess_match_ip'] = FALSE;
$config['sess_time_to_update'] = 300;
$config['sess_regenerate_destroy'] = FALSE;

You forgot the echo command. Try:

PHP Code:

 <p class="alert alert-danger"><?php echo $msg;?></p> 


Or with the shorthand notation:

PHP Code:

 <p class="alert alert-danger"><?= $msg;?></p> 


OMG, thank you Wouter60
