Flashdata always seems one page behind - El Forum - 02-27-2008

Hi there,
just started trying to use the flash. It seems that it is always 1 request behind. Consider the following code
Code:
$this->session->set_flashdata( 'flash', 'You have already provided us with your details' );
$this->load->view( 'competition_form' );The flash message doesn't show the first time the view is loaded, only if refreshed. How can one get it to show in the view file?
I am actually trying to use it along with form validation and my full code looks like this:
Code:
if( $this->validation->run() == FALSE )
{
$this->session->set_flashdata( 'flash', 'Please fill in the form correctly…' );
}
else
{
if( !$this->session->userdata( 'competition' ) )
{
$this->load->model( 'entry' );
$this->entry->saveEntry();
$this->session->set_userdata( 'competition', TRUE );
$this->session->set_flashdata( 'flash', 'Thank you. Your details have been saved and a confirmation email sent.' );
}
else
{
$this->session->set_flashdata( 'flash', 'You have already provided us with your details. Multiple submissions are not allowed.' );
}
}
$this->load->view( 'competition_form' );Flashdata always seems one page behind - El Forum - 02-27-2008

The definition of flashdata is that it shows on the next page load. No the next view load. If you need text in a view just pass it as part of the data array.

thanks for the reply. So in what circumstance might you want to use flash data? Just so I can get some idea of when it might be useful for me. Thanks a lot.

The manual gives a few examples of circumstances gabe, take a look. I also gave a few examples on my blog when I originally wrote these. http://www.derekallard.com/blog/post/enhanced-codeigniter-session-library/

I use flash say when an event happens, such as creating an account, logging in, posting..etc
Nice feedback for the user.
