flashdata not working as expected without redirect() - El Forum - 09-30-2010

Hi all,

I am developing an application that makes use of session->flashdata() for error/success messages on pages that use forms.

As the admin of the site, I also use the Profiler to track what queries are being executed. When I enabled the profiler, I noticed that some of the queries were not showing up. For example, when a user wants to update their profile, a db->update() function is executed.

After some digging, I realized that when I update the database, I set a flashdata variable and redirect to the same page, and the queries were not being saved to display in the profiler, but the flashdata never fails. When I modify my controller to load->view() instead of redirect(), the profiler shows the query, but now my flashdata is all messed up - it will never show until the next page load (sometimes 2 page loads.)

All I did was comment out the redirects, as shown below.

Controller:

Code:
if ($this->form_validation->run() !== false){

  $upd = $this->users_model->update_user($clean, $user->email);

  if ($upd){

    $this->session->set_flashdata('message', '<p class="success">Your profile has been updated.</p>');

    //redirect('auth/edit_user/'.$user->id);

  } else {

    $this->session->set_flashdata('message', '<p class="fail">Something went wrong, please try again or contact the helpdesk.</p>');        

    //redirect('auth/edit_user/'.$user->id);

  }

}

//this block executes if the form is not submitted, and/or after the validation succeeds/fails. 

$data['content'] = "auth/edit_user";

$this->load->view('template', $data, false);

View:

Code:
<h1>Edit Your Profile</h1>

<div class="message">&lt;?php echo $this->session->flashdata('message');?&gt;</div>

//form stuff...

Other information that may be useful:

Config:

Code:
$config['sess_use_database'] = TRUE;

Is there a better (native CI) solution for success/error messages other than using session->flashdata()? I'm not opposed to adding an extra library or a function to one of my custom helpers, but it seems like this can be fixed without a bunch of excess coding.

If this post is not in the right area, can a mod please move it?

Thanks,

Quote:Flashdata

CodeIgniter supports "flashdata", or session data that will only be available for the next server request

You could try my Message Library which solves this.

What happens when you try

Code:
if ($this->form_validation->run() !== false){

  $upd = $this->users_model->update_user($clean, $user->email);

  if ($upd)

    $this->session->set_flashdata('message', '<p class="success">Your profile has been updated.</p>');

  else

    $this->session->set_flashdata('message', '<p class="fail">Something went wrong, please try again or contact the helpdesk.</p>');        

  redirect('auth/edit_user/'.$user->id, 'refresh'); 

}

@noctrum
So loading a view doesn't really make another http request?

@pickupman
If your solution does not work, I will try n0xie's library.

Thanks for the replies!

No... redirect() makes another http request

--Edited--

My question changed, so I will make another post. Thanks for the help -- I am going to use n0xie's message lib.
