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?

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)]."\"><< Previous</a>\n";
}
if($i != (count($page) - 1)) {
echo "<a href=\"".$page[($i + 1)]."\">Next >></a>\n";
}
include('page'.$i.'.htm');
?>

Totally would work for his purposes but let's clean it up a bit for a
beginner.
<?
$page = array('page1.htm','page17.htm','page5.htm'); // array of the pages
you have
if(isset($_GET['page_num'])) // a current page number has been set in the
url
{
$i = $_GET['page_num']; // set variable i to the current page number
if($i != (count($i)-1)) // if the current page number isnt the last
entry in the array display next
echo "<a href=\"".$page[($i + 1)]."\">Next >></a>\n";
if($i != 0) // if the current page isn't the first page display
previous
echo "<a href=\"".$page[($i - 1)]."\"><< Previous</a>\n";
}
include('page'.$i.'.htm'); // show the current page you're at
?>
