I made a "custom" recordset paging function to allow me to
put a link to
more articles.
Here is how I did it:
On my index page, I have an included page, nl_FrontPage, for
newsListings,
Front Page.
I created a DW recrodset, limited to a variable on the page
(4 articles).
I then manually set the page # with another variable in the
page call:
on index.php:
<?php
$mcPage=0;
$mcArticles=4;
$fpStyle=1;
include("nl_FrontPage.php")
?>
Now, on my news.php page, I again include the nl_FrontPage to
capture any
"front page articles" not shown on the front page. the page
call looks the
same:
if(empty($_GET['mcPage'])){
$mcPage = 1;
}else{$mcPage=$_GET['mcPage'];}
//can put cookie call in here to get more articles
$mcArticle = 4;
$fpStyle = 0;
require("app/nl_FrontPage.php")
Next, I have this little function to do my recordset paging:
function create_paging_menu($a){
$b=$a;
$c=$a;
$b--;
$c++;
$d="<div class=\"menuPaging\"><a
href=\"news.php?mcPage={$b}\">Previous
Page</a> <a href=\"news.php?mcPage={$c}\">Next
Page</a>";
print $d;
}
Everythign works fine except for this:
When I don't have any future records to show, my menu still
shows up. I can
count the articles being displayed and match that to my
$mcArticle number,
and if displayed<$mcArticle, I obviously have no more
articles to show, but
that still elaves a whole - how to know "if the *next*
recordset paging has
any records.
Can somebody give me some direction?
