Multiple file upload, resize and store in different tables.

Personally I would rewrite the insert_images too and make use of insert_batch instead, so that you don't need to make a foreach loop.

PHP Code:

public function submit(){
   if ($this->session->userdata('logged_in') == true) {
     $user_id = $this->session->userdata('user_id');
     $data['user'] = $this->user_model->get_user_data($user_id);
   }
   $data['categories'] = $this->pet_model->get_pet_category();
   $data['sizes'] = $this->pet_model->get_pet_sizes();

   $this->form_validation->set_rules('petTitle', 'Title', 'required');
   $this->form_validation->set_rules('pet_category', 'Category', 'required');

   if($this->form_validation->run() === FALSE){
     echo validation_errors();
   } else {
     // Single
     $pet_entry_id = random_string('numeric', 6);

     $dir_exist = false; //Directory exist
     if ( !is_dir('assets/img/pets/' . $pet_entry_id) ) {
       mkdir('./assets/img/pets/' . $pet_entry_id, 0777, true);
       $dir_exist = true; // dir not exist
     }

     // Multiple
     $images = array();
     if( !empty($_FILES['images']['name']) ){
       $countfiles = count($_FILES['images']);
       for($i=0; $i<1; $i++){
         if(!empty($_FILES['images']['name'][$i])){
           $_FILES['image']['name'] = $_FILES['images']['name'][$i];
           $_FILES['image']['type'] = $_FILES['images']['type'][$i];
           $_FILES['image']['tmp_name'] = $_FILES['images']['tmp_name'][$i];
           $_FILES['image']['error'] = $_FILES['images']['error'][$i];
           $_FILES['image']['size'] = $_FILES['images']['size'][$i];

           $config['upload_path'] = './assets/img/pets/' . $pet_entry_id;
           $config['encrypt_name'] = TRUE;
           $config['allowed_types'] = 'gif|jpg|jpeg|png';
           $config['max_size'] = '1310720';
           $config['max_width'] = '2048';
           $config['max_height'] = '2048';

           $this->load->library('upload', $config);

           if ( $this->upload->do_upload('image') ) {
             $image_data = $this->upload->data();
             $config['image_library'] = 'gd2';
             $config['source_image'] = $image_data['full_path'];
             $config['maintain_ratio'] = TRUE;
             $config['width'] = 650;
             $config['height'] = 650;

             $this->load->library('image_lib', $config);

             $images[] = $image_data['file_name'];
           }
         }
       }
     } else {
       if($dir_exist)
       rmdir('./assets/img/pets/' . $pet_entry_id);
       $image = 'default_petavatar.png';
     }
     if( ! empty($images) )
     {
         $image = array_shift($images);
         $this->pet_model->create_pet($image, $pet_entry_id);
         if( ! empty($images) )
         {
             foreach($images AS $img)
             {
                $this->pet_model->insert_images($img, $pet_entry_id);
             }
         }
     }

     redirect('pets');
   }

   $this->render_page('pets/submit', $data);
 } 


Sorry for being late to answer but i was trying to insert it in my code and clean some other parts of the code.
One issue is that while it uploads the first image of the array, the others do not pass in the "foreach" loop and they are not uploaded in db neither in the folder..
Any ideas?!

[EDIT]: I'm just an idiot! I had the number "1" instead of the countfiles number in the "for" loop! It works perfectly! May i ask if you know any good plugins for previewing - deleting - editing images before uploading? I've searched all over the internet and foudn nothing.
