The ODP module displays the popular Open Directory inside
your PHP-Nuke site (Figure 8-31). It is based on the phpodp
class. The whole functionality is encapsulated in the phpodp class in odp.php. The PHP-Nuke module practically only calls the odp.php script.
If you would like to import all links of an ODP category into your Web Links or Downloads module, have a look in Section 27.5 and Section 27.6 respectively for some interesting procedures.
