adding numbers together

JD_

i have a few pages with articles on and and it works like ?x=hardware&id=1&pg=1 etc

and on the page where the article is displayed i want a NEXT link when click goes to the next page of the current article so i want it to work out what the next page will be something like.

take $id + 1 = $next then i can put <a href="<? echo "$next" ?>Next</a>

i know this is probably simple but ive never done anything like this.

$id=$_GET['id'];
$id++;
$next="sompage.php?x=hardware&id=".$id."$pg=1";
echo "<a href=\"$next\">Next</a>";

you could try:

<a href="<?php
$next = $_GET['id'] + 1;
echo $_SERVER['PHP_SELF'] . '?x=hardware&amp;id=' . $next;
?>">Next</a>

arg should have asked this as well i will need a previous link as well i figured how to reverse the above procedure but i need to only show it when $pg is higher than 1 and i need to make a copy of the variable or something first i tired this but dosent seem to work

<? $pg=$_GET['pg'];
$pg++;
$next="index.php?x=hardware&id=$id&pg=$pg"; 
echo "<a href=\"$next\">Next</a>" ?><? if ($prev > 1) { $prev = $pg;
$prev--;
$previous="index.php?x=hardware&id=$id&pg=$prev"; echo "-<a href=\"$previous\">Previous</a>";} else "" ?>

any suggestions?

<? 
$pg=$_GET['pg'];
$temp_page = $pg;
$next_page = $temp_page++;
$prev_page = $temp_page--;

$next_link = "index.php?x=hardware&id=$id&pg=$next_page"
$prev_link ="index.php?x=hardware&id=$id&pg=$prev_page"; 

echo "<a href=\"$next_link\">Next</a>";
if($prev_page > 1)
	echo "<a href=\"$prev_link\">Previous</a>";

?>
