Process of prepping

[eluser]williamparry[/eluser]
Hi,

I've been reading the documentation about "prepping data" and I am wondering if someone could give me a practical example of doing this with a database?

If I have:

Code:

$rules['firstName']        = "trim|required";

How can I insert the trimmed data into the database? What variable do I use?

Once the validation runs the post data is overwritten with the new values.

So in this case just do

Code:

$this->input->post('firstName');

If I do that, it ignores my rules. I've tried it with passwords and md5 and it just ignored converting it to md5.

Make sure you run the validation first:

Code:

if ($this->validation->run() == FALSE)
{
    //Changed, but validation error
}
else
{
    //Insert them into db here
}

EDIT: Also make sure you called $this->validation->set_rules($rules);
