For some reason, the flashdata is cleared just before the view is loaded. As the log shows below.
[04/02/2021 13:45:04] INFO: START: result $item {"userdata":{"__ci_last_regenerate":1612417338,"updateeventsuccess":"Event updated successfully","__ci_vars":{"updateeventsuccess":"old"}}}
[04/02/2021 13:45:04] INFO: START: result $item {"userdata":{"__ci_last_regenerate":1612417338}}
How my program flows is that from the initial page, which I will call 'home', I click a link which brings me to an edit page, called 'form', where data fields are found. After filling out the data fields, I will submit the data. In the controller, flashdata is used to store a message about the submission of the data. Then redirect() is used to redirect back to 'home' via its controller method.
Form code where ajax happens:
webix.ajax().post(
'<?php echo base_url() . 'index.php/Administration/EventController/SaveOrUpdate';?>',
form.getValues(),
function(){
location.href = "<?php echo base_url() . 'index.php/Administration/EventController/Listing';?>"
});
The controller method where redirect() is used:
public function SaveOrUpdate()
{
$this->RequireRole('admin');
$this->load->model('Event');
//get form post data
$event_form_data = $this->ProcessPostData();
//get post assigned roles
$post_roles = $this->input->post('roles');
//check if is add or edit
if($event_form_data->Id <= 0)
{
//if add, insert race
$inserted_id = $this->Event->Insert($event_form_data);
//if successfully inserted/not
if($inserted_id!=null){
$this->session->set_flashdata('inserteventsuccess', 'Event inserted successfully');
}else{
$this->session->set_flashdata('inserteventfail', 'Failed to insert the event');
}
}
else
{
//if update, update race
$updated = $this->Event->Update($event_form_data->Id, $event_form_data);
// if successfully updated/not
if($updated){
$this->session->set_flashdata('updateeventsuccess', 'Event updated successfully');
}else{
$this->session->set_flashdata('updateeventfail', 'Failed to update the event');
}
}
//redirect('/Administration/EventController/Listing'); EDIT Stackoverflow 04/02/2021: Remove this to solve bug.
}
Finally, the controller method for 'home' where view is loaded:
function Listing() {
$this->RequireRole('admin');
$this->load->model('Prospect');
$this->load->model('Auth/User');
$this->load->model('Event');
//get user Id(email) and user Name
$user_email = $this->GetUserId();
$user = $this->User->GetByUserId($user_email);
$data['user'] = $user_email;
$data['username'] = $user->Name;
$data['users'] = $this->User->GetAll();
$data['events'] = $this->Event->GetAll();
//check whether user is admin/manager
$user_roles = $this->GetUserRoles();
$data['admin'] = false;
$data['manager'] = false;
foreach($user_roles as $key){
if($key=='admin'){
$data['admin'] = true;
}
if($key=='manager'){
$data['manager'] = true;
}
}
// $this->session->keep_flashdata('updateeventsuccess');
$message = 'START: result $item '.json_encode($this->session);
$timestamp = date('d/m/Y H:i:s');
$log_file = 'EPAerror_script.log';
error_log('['.$timestamp.'] INFO: '.$message.PHP_EOL, 3, $log_file);
//load dialect listing page
$data['title'] = 'Event Listing Page';
$this->load->view('templates/header',$data);
$this->load->view('templates/navbar',$data);
$this->load->view('Event/Listing',$data);
$this->load->view('templates/footer');
}
Some solutions I have tried is to use keep_flashdata() but it ends up being stored even after refresh and is not cleared from flashdata. This can be seen in the log below:
[04/02/2021 13:59:09] INFO: START: result $item {"userdata":{"__ci_last_regenerate":1612418277,"updateeventsuccess":"Event updated successfully","__ci_vars":{"updateeventsuccess":"new"}}}
[04/02/2021 13:59:11] INFO: START: result $item {"userdata":{"__ci_last_regenerate":1612418277,"updateeventsuccess":"Event updated successfully","__ci_vars":{"updateeventsuccess":"new"}}}
Any advice on how to work around this?
