is_int issue?

$this->uri->segment() returns a string, or boolean FALSE if the segment doesn't exist. So, it will never be an int unless you cast it like $gallery_id = (int)$gallery_id; If you do that though, it will never be boolean FALSE, it will be 0 in that case.

Code:

else if($action == 'edit')
{
  $gallery_id = $this->uri->segment(5, FALSE);
  
  //if the segment exists, cast it as an int or else trigger 404
  if ($gallery_id !== FALSE)
  {
    $gallery_id = (int)$gallery_id;
  }
  else
  {
    show_404();
  }              
}

You can check for yourself by running var_dump($gallery_id); right after you get it from the segment before doing anything else.
