Value of member variable disappears in CodeIgniter/PHP -

i have situation of loosing value stored in $member variable.

class user extends ci_controller {     protected $message;      function list()     {         $data['message'] = $this->message; // it's empty         $this->load->view('view', $data);     }      function delete($id)     {         $this->user_model->delete($id);         $this->message = "success";          redirect('user/list');     }  } 

the reason of using redirect clean url. empty value $this->message in list() after getting redirected.

i tried making static, still no luck.

you try using flash messages:

function delete($id) {     $this->user_model->delete($id);     $this->session->set_flashdata('message', 'success');      redirect('user/list'); } 

for need load session library in constructor of controller:

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

in view use this:

<?php echo $this->session->flashdata('message');?> 

you can preserve data in flash messages several requests this:

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