The viewers are PHP pages which you create and upload. You might have the following pages:
newsList.php - a list of news items
newsDetail.php - show details on _one_ news item.
When you go to newsDetail.php you can put a number of the end of the record number you want to view, like this:
newsDetail.php?33 - Display news record 33
You could manually create that link in newsList.php like this:
<a href="newsDetail.php?<?php echo $record['num']">link</a>
But to make it easier for you we automatically create a special field called _link that has the "viewer url" and number in it (as well as some extra title text for search engines). So using _link your link looks like this:
<a href="<?php echo $record['_link']">link</a>
But since you can create an unlimited number of viewers we don't know where to link to find the news detail page. So that's why we let you specify the viewer urls in the admin section.
That last bit of code might create a link like this:
http://example.com/newsDetail.php?News-title-goes-here-33
Hope that helps. Let me know if I can provide more detail or clear up anything else. :)
