Array to string conversion

[eluser]Colin Williams[/eluser]
This is completely untested but I think it will work. A good starting point nonetheless

Code:

class MY_Upload extends CI_Upload {
  
   function MY_Upload()
   {
      parent::CI_Upload();
   }

   function do_multi_upload($field = 'userfile')
   {
      $success = FALSE;
      if (is_array($_FILES[$field]['error']))
      {
         // Create a pseudo file field for each file in our array
         for ($i = 0; $i < count($_FILES[$field]['error']); $i++)
         {
            // Give it a name not likely to already exist!
            $pseudo_field_name = '_psuedo_'. $field .'_'. $i;
            // Mimick the file
            $_FILES[$pseudo_field_name] = array(
               'name' => $_FILES[$field]['name'][$i],
               'size' => $_FILES[$field]['size'][$i],
               'type' => $_FILES[$field]['type'][$i],
               'tmp_name' => $_FILES[$field]['tmp_name'][$i],
               'error' => $_FILES[$field]['error'][$i]
            );
            // Let do_upload work its magic on our pseudo file field
            if (!$this->do_upload($pseudo_field_name))
            {
               $success = FALSE;
               break;
            }
            else
            {
               $success = TRUE;
            }
         }
      }
      else
      // Works just like do_upload since it's not an array of files
      {
         $success = $this->do_upload($field);
      }
      return $success;
   }
}

What I'm doing here is making copies of files from the array of files, then passing these copies onto the existing do_upload() method to process them. It's better than overriding the beast that is do_upload(), and it's probably a bit future-proof/less-hackish to not override a core library method.
