$this->session->userdata('isuploadvisible');

severity: notice  message: undefined property: grocery_crud::$session  filename: views/add.php  line number: 2

this add.php 1 can found in

  assets/grocery_crud/themes/datatables/views/add.php

you use $this somewhere refers this grocery_crud class. try this:

$ci =& get_instance(); $ci->session->userdata('isuploadvisible');
