Cart Library - Multi dimensional array

[eluser]Ray G[/eluser]
I am using the cart library and having a problem inserting a multi-dimensional array. The array seems fine but only the first will insert. Here is the code to create the array and insert items

Code:

// Add an item to the cart
function validate_add_cart_item($postdata){
    //print_r($postdata['pnpattr']);
    $qty = 1;                 // Assign posted quantity to $cty
  $pkg = $postdata['pkg'];
    $i=0;
    foreach($postdata['pnpattr'] as $items)
    {
      //echo 'hello<br>';
    $item = explode('|', $items);
    $id = $item[0];     // Assign posted product_id to $id
    $code = $item[1];   //
    $color = $item[2];

    $this->db->where('id', $id); // Select where id matches the posted id
      $this->db->where('qoh !=', '0'); // Select where id matches the posted id
    $query = $this->db->get('inventory', 1); // Select the products where a match is found and limit the query by 1
      $rows = $query->num_rows();
      $row = $query->row();
      $query->free_result();
      //echo "<br>$rows<br>";
      //echo $this->db->last_query();
    // Check if a row has been found
      $error = array();
    if($rows > 0){
      //echo 'hello<br>';
        // Create an array with product information
        if($pkg == '1')
        {
          $data[] = array('id' => $id, 'qty' => $qty, 'price' => '14.95', 'name' => $row->desc, 'options' => array('pcode' => $code, 'pcolor' => $color, 'pkg' => $pkg));
          //$this->cart->insert($data);
        } else {
          if($pkg == '2' && $i == 0)
         {
           //echo "<br>$i";
          $data[] = array('id' => $id, 'qty' => $qty, 'price' => '19.95', 'name' => $row->desc, 'options' => array('pcode' => $code, 'pcolor' => $color, 'pkg' => $pkg));
            //$this->cart->insert($data);
            $i++;
         } else {
           if($pkg == '2' && $i == 1)
            {
              //echo "<br>$i";
              $data[] = array('id' => $id, 'qty' => $qty, 'price' => '0', 'name' => $row->desc, 'options' => array('pcode' => $code, 'pcolor' => $color, 'pkg' => $pkg));
              //$this->cart->insert($data);
           }
          }
        }
      // Nothing found! Return FALSE!
    }else{
      $error[] = 1;
    }
    }
    $this->cart->insert($data);
    print_r($data);
  }

Variable $postdata['pnpattr'] is formatted as "2|PNPCAR|Candy Apple Red"

Which produces this array
Array ( [0] => Array ( [id] => 2 [qty] => 1 [price] => 19.95 [name] => Prep N Pop (Candy Apple Red) [options] => Array ( [pcode] => PNPCAR [pcolor] => Candy Apple Red [pkg] => 2 ) ) [1] => Array ( [id] => 1 [qty] => 1 [price] => 0 [name] => Prep N Pop (Licorice) [options] => Array ( [pcode] => PNPLB [pcolor] => Locorice Black [pkg] => 2 ) ) )

Any help appreciated

Thanks
