Need Help With Form Submission

[eluser]vincej[/eluser]
Ok - CroxNix - if I could buy you a beer I'd buy you 10!
Changed my query to include, puid. so it now read:

Code:

function Updatelocation(){
    foreach( $_POST as $pickupid=>$location) {
    $data = array(
  'puid' => db_clean($_POST['puid']),
  'dates' => db_clean($_POST['TheDates[0]']),
  'dates' => db_clean($_POST['TheDates[1]']),
  'dates' => db_clean($_POST['TheDates[2]']),
  'dates' => db_clean($_POST['TheDates[3]'])
    );
  $this->db->where($_POST['puid'], 'puid');
  $this->db->update('pudates',$data);
  $this->session->set_flashdata('message', 'Table Updated');
   }
  
  }

and I still get "undefined Index TheDates[0]" through to [3]

I'm also getting:

Cannot modify header information - headers already sent by (output started at C:\xampp\htdocs\CountryLane\system\core\Exceptions.php:185)
