CodeIgniter “flashdata” doesn't work

Question

I use CodeIgniter 2.1.0, i want after insert data in database get a message like \"Your information was successfully updated.\". For this work i have in CI_Controller follow

Answer 1

I had the same problem. After checking the code I have found, that I am calling $this->session->sess_destroy();, which causes the problem.

Answer 2

As I am observing about codeigniter flashdata. When I use it in second request using codeigniter redirect() method it is working fine in mozila but in the case of chrome it is not working.

Answer 3

I had Chrome developer console open and flashdata was removed. After closing it and retrying it works. Version 71.0.3578.98 (Official Build) (64-bit)

Answer 4

I had that problem too. I don't remember where I saw but here's my solution.

redirect('url/myurl','refresh');

CodeIgniter didn't treated redirect as another request. So flashdata wasn't set in the redirect, but it was on the next page I loaded.

Answer 5

Except one page, I am able to display/pass values using session. I tried using the var_dump($this->session) and I get:

["flash:old:Array"]=> bool(false)
["flash:new:message"]=> string(10) "My Message"

I have tried echoing the flash data within the page without redirecting just after setting the data, but the result was same. I recommend to trim down the code, and try to set session in other pages. If the problem persists check your var_dump. This might not be the solution, but I think it can help.

UPDATE : trimming down spaces and newlines within the text worked. I was passing 2 long sentences with empty line breaks and spaces.

if (0) //Assume this condition is false
{   
    $this->load->view('error_page');
    // Generate validation error
}
else
{
    //Show success message
    $data = array(
                'message' => 'My message'
                           );
    $this->session->set_flashdata($data);
    $this->session->keep_flashdata($data);                      
    echo $this->session->flashdata('message');
    //echo var_dump($this->session);
    //redirect(base_url().'success_page');
}

Answer 6

I know I am very late but I was having this problem and I couldn't believe that in my case the solution was very easy

just replace

$this->session->flashdata('message');

to

print_r($this->session->flashdata('message'));
