Novice Question: I would like to create a set of pages that could use some kind of logic to have "previous - next buttons "so that when the button was clicked it would automatically go to the next page - or the previous page. I know very little about PHP ... however, I am hoping that there is some kind of preset " open source" php code that I might be able to use. I can envision something like this: - An 'include page' that might store an array of the list of pages such as: start array... pos1 = page1.htm pos2 = page17.htm pos3 = page5.htm etc..... stop array... - then a variable could be set for the current page such as: thispage = 2 - Place on the array equals position 2 (page17.htm) then the next button would add 1 to the current place on the array- (pos3) - and the previous button would be minus 1 place on the array - (pos1) ... that type of thing Q: Is there any "open source" code template that I can check out like this? -- Thanks - RevDave CoolCat@hosting4days.com [db-lists] -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

There are several ways to do this, but here's one way: <? $page[] = "page1.htm"; $page[] = "page17.htm"; $page[] = "page5.htm"; // Or you can do: // $page = array('page1.htm','page17.htm','page5.htm'); session_start(); // For storing the user's current position if(!$_GET['page_num']) { $i = 0; } if($i != 0) { echo "<a href=\"".$page[($i - 1)]."\">&lt;&lt; Previous</a>\n"; } if($i != (count($page) - 1)) { echo "<a href=\"".$page[($i + 1)]."\">Next &gt;&gt;</a>\n"; } include('page'.$i.'.htm'); ?> -- Daniel P.
