[quote author="brian88" date="1337196196"]Thanks. both are good answers. I did boltsabre's way. And now I wanna do PhilTem's way also.

I made a new column "images"

So now I can store all the trucks into this column with a serialized array?

I showed all my code above but heres the model and updated controller code.
Where can i serialize the data then unserialize for the view?

model

Code:

function addTruck($data){
  //$d = serialize($data); // dont work
  $insert = $this->db->insert('trucks', $data);
  return $insert;
} // end function

controller updated code

Code:

function index() {
   // get all trucks from database
   $data['trucks'] = $this->main_mod->getTrucks();

   $data['num_of_images'] = 5;

   // if user presses submit button
  if($this->input->post()){
   // get the name of the truck
   $db_data['name'] = $this->input->post('name');
   // format the truck name to be a folder name
   $folder = str_replace( " ", "", strtolower($this->input->post('name')) );
  
   // if the name of the truck folder does not currently exist.
   if(!is_dir('assets/images/'.$folder)){

    // make a folder based off the name of the truck
    mkdir('assets/images/'.$folder, 0777);

    // config for file uploads
    $config['upload_path'] = FCPATH . 'assets/images/' . $folder;
    $config['allowed_types'] = 'gif|jpg|png|jpeg';
    $config['max_size'] = '0'; //1000 = 1MB
    $config['max_width']  = '0';
    $config['max_height']  = '0';
    $this->load->library('upload', $config);
    
    // upload users submitted images
    for ($i=1; $i<=$data['num_of_images']; $i++){
     // if user uploaded an image
     if ( !empty($_FILES["file" . $i]['name']) ){
      // upload file
      if($this->upload->do_upload("file".$i)){
       $upload_data = $this->upload->data();
       $db_data["images"] = $folder.'/'.$upload_data['file_name'];
      }else{ // error
       echo $this->upload->display_errors();
      }
     }
    }

    // add to database
    $this->main_mod->addTruck($db_data);

    // refresh the page to see view new data added.
    redirect('/');

    // Debug
    foreach($db_data as $d){
     echo serialize($d) . '<br /><br />';
     // uploaded 1 photo....it returns
     // s:9:"truckname";
     // s:18:"truckname/logo.jpg";
    }
   }else{
    // The truck name folder exist. Need a new name for the folder.
    echo 'Error: This truck name already exist. Choose a different name.';
   }
  }else{
   // views
   $data['content'] = 'main/post';
   $this->load->view('templates/main', $data);
  }
  
} // end function

I tried

Code:

serialize( $db_data["images"] ) = $folder.'/'.$upload_data['file_name'];

But that fails.[/quote]

Hey dude store file name in image array like this.

Code:

$db_data["images"][] = $folder.'/'.$upload_data['file_name'];
