Entity Reference

I found out a better way to provide "Add content" link at the footer region of a VIEW. We can achieve followings:

- Pass any number of arguments.
- User can access link only if he/she has permission.

N.B- use Entity Reference for prepopulating valued from URL

Example:

<?php
global $user;
$view = views_get_current_view();
$args = $view->args[0];
if (user_access('create test_report content', $user)) {
$output=l(t('Add new Biochemistry Test '), 'node/add/test-report', array(
'query' => array(
'field_tr_patient_ref' =>$args,
