Display alert message and redirect after click on accept

Question

Well, I have a page with links to reports. Whenever somebody clicks on one report, they can download the excel file. However, sometimes there are no fields to make a report;

Answer 1

Combining CodeIgniter and JavaScript:

//for using the base_url() function
$this->load->helper('url');

echo "";

Note: The redirect() function automatically includes the base_url path that is why it wasn't required there.
