we dont have a tutorial for this no.
when you go to the detail page, make not of the address in the address bar, it will contain a URL variable that passes the product id, for example:
details.php?productID=3
in this example, the product id is passed by a URL variable named:
productID
you will need to create a recordset that filter the productID column on the product ID URL variable, for example. using the advanced recordset interface, set the recordset select statement as:
SELECT productID FROM products WHERE productID > paramID ORDER BY productID ASC LIMIT 1
in the variables section, create a new variable as:
Name: paramID
Data Type: integer
Default Value: -1
Runtime value: $_GET['productID']
then create the next link using the recordset productID binding for the value of the URL variable:
<a href="details.php?productID=<?php echo $row_recordsetName['productID']">Next</a>
you will want to use the Show Region behavior to only show the link if the recordset is not empty.
