Using Flashdata to pass data through a redirect()

Using Flashdata to pass data through a redirect().

Is this a good idea? What are the potential security risks associated with this?

Also, I have recently started conforming to the way that the tutorials do things, and instead of writing forms that POST to themselves

Example:

Code:

<form method="post" action="">

and handling the information with IF's, I have begun having them go to individual Controller functions,

Example:

Code:

<form method="post" action="<?php echo site_url().'/controller/do_edit_blog'; ?>">

and that is where my need comes in to have data passed through redirects.

Now, if this isn't the preferred method, I would like to stop doing it this way before I get used to it. So to you guys, the community, what do you think?

Thanks!
