How to check if form was submitted in the view - El Forum - 01-22-2012

I'm trying to do the following: I would like to have 1 view that is used for the form and the form validation and the form success as well. I'm using flashdata to inform the user about the process. But I would like to check wether or not the following code in the view is considered safe and good practice.

I placed this line:

Code:
$this->session->set_flashdata('exito', 'some message');

only to show when the form was saved to the database, so I should be covered right?

form_view.php

Code:
&lt;!-- Flash Data --&gt;

   &lt;?php if ($this->session->flashdata('success')) { 

       echo '<div class="msj success">'.$this->session->flashdata('success').'</div>'; 

   } elseif ($this->session->flashdata('error')) {

    echo '<div class="msj error">'.$this->session->flashdata('error').'</div>'; 

   } ?&gt;

   &lt;!-- if form was sent succesfull  --&gt;

   &lt;?php if($this->session->flashdata('success')) :?&gt;

    // Thank you message and some information about the next steps to follow...

   &lt;?php else :?&gt;

   &lt;!-- Render form --&gt;

         // Render form

                        &lt;?php endif :?&gt;

Unless you are redirecting after the form is processed, you don't need session data. Just pass a variable to your view like you would any other data, and give it a true or false value saying whether or not the form was processed successfully.
