Codeigniter和重定向过期的URL

Question

I have a site built with codeigniter. Everything is working great except, I have a news area with a setof pages that disappear after a set amount of time. When people access the old links I want to redirect them to a different page. The rub is the links are www.site.com/controller/function/page-id-with-numbers-0098468854. If someone accesses the link it works great. What i would like to route away is mistyped page ids and deleted ids redirect to a sorry page moved page, or better yet homepage with an alert or message.

Answer 1

You can use show_404() CI Document here

At first, parse uri segment with this and get page ID

$this->uri->segment(n);

Check DB page id exist or not and show 404 page like below:

if(mysql_num_rows($result) == 0)
{
   show_404();
}
