thanks {Djordje Zeljic} it works!! you reply quickly
please how to empty post if form_validation->run() is true?

[eluser]Djordje Zeljic[/eluser]
if you think how to empty $_POST?

Code:

unset($_POST);

or

Code:

$_POST = null;

and, why you need to empty "post"?

after post a comment i need to empty all post of the form! that is to prevent user to repost same value!

[eluser]WanWizard[/eluser]
That doesn't really help, POST information comes from the client. If the user reloads his browser, or uses the back button and submits the form again, you'll get a new POST array with all the form values...

The only safe way to prevent this is to add a token to the form, and check using a form validation rule if the token in the submitted form has been used before. If so, it's a double post. You can use that same token for CSRF protection.
