so how to use this?

submit to insert the record into the database and with 3 click times and had 3 same records, so that it's not good for my aim, i just want only record will be insert into db[/quote]

I made my own CSRF library, and you can use it too if you want:

https://bitbucket.org/skunkbad/community...s/csrf.php

Use is really easy, especially if you use the MY_form_helper:

https://bitbucket.org/skunkbad/community...helper.php

All you have to do is load the library in your controller:

Code:

$this->load->library('csrf');

Then, to check for valid form submission:

Code:

if( $this->csrf->token_match )
{
   // ...
}

CodeIgniter has it's own CSRF protection now, but this library can be used in older version of CI, or in combination with CI's CSRF protection. It's been fully tested and I use it every day.
