I don't know if this will help, but you need to check the return of the save function, every time. It should always look like this:

Code:

if($u->save()) {
    // Everything was saved OK
} else {
    // An error occurred, check $u->error
}

I know the examples in the manual aren't very clear about this, but the example application is better. Even if you don't use the HTMLForm extension, the pattern is the same:

Code:

function edit($id) {
    $o = new Object($id);
    if(isset($_POST['submit'])) {
        $o->value1 = $_POST['value1'];
        if($o->save()) {
            redirect('wherever');
        }
    }
    $this->load->view('edit', array('object' => $o));
}

Then, in your view, you can handle showing errors. If the item hasn't been edited yet (ie: not submitted), there are no errors. If it was submitted and there were no errors, the page is redirected. If it was submitted and there are errors, then you can see them in $o->error.

The SQL UPDATE is never run before the validation. Validation is the first thing the save function does.
