Update Form Validation

[eluser]Jaketoolson[/eluser]
Within the controller you should do the DB vs $_POST comparison/processing/merging of the results then pass a results array to the view.

Here's a very bland example:

Code:

// $options = the DB array.
// $_POST = the $_POST array.  
// array_merge will overwrite existing key->value pairs (if they exist).

$options = array('ridetime' => '2 hours', 'distance' => '26 miles');
$_POST = array('distance' => '28 miles', 'ridedate' => '2011-02-01');

$data = array_merge($options,$_POST);

// $data outputs the following array:
array (
  'ridetime' => '2 hours',
  'distance'  => '28 miles',
  'ridedate'  => '2011-02-01'
)

$this->load->view('update', $data);

As it pertains to form validation rules, you can create an array with rules and use them throughout the site. See 'Setting Rules Using an Array'.
