Ok, Let me if I undestand you,
First at all, you need to add fields on your database that contains the information of the pages or links created.
In the First page loaded qhen loggin succes, you need to add a simple php code for example, that loads the data from the database, and create a dynamic reload option for the page.
the php code for load data from pages is:
global $ID; // the ID is the var for the user, this must be on the database
// as the first line
..... some of you
In the dymanic.php file you need to load the database
/// the code of the connection of mysql and load the database
echo '<META HTTP-EQUIV="Refresh" CONTENT="5; RL='.$page.'">';
// take care that the CONTENT value is the ammount of seconds to refresh and redirect a page.
