The simplest way to make sure everything work well regardless of what the
values are:
<?
$url = "somepage.php?var1=".urlencode($var1)."&var2=".urlencode($var2);
echo "<a href=\"".htmlspecialchars($url)."\">";
?>
htmlspecialchars() changes characters '&', '"', ''', '<', '>' into the HTML
equivilant. And yup, you should do this for all *ML pages as long as the
thing being printed is not part of the mark-up syntax.

Hi, Rory

I think you have the idea. The &'s are used to seperate the various
variables. If you want to set $p to something like 'Tom & Jerry' then
personally I'd do something like:
<?php
$p = "Tom & Jerry";
$s = "Cat & Mouse";
printf("<a href='{$_SERVER['PHP_SELF']}?p=%s&s=%s", urlencode($p),
urlencode($s));
?>
That's nice. To get more specific (because my code varies a bit from
yours and I don't wanna mess up the ) and ' and " s:
$p and $c are actually row ID numbers so up to 3 digits. So for example
if
$p=1
$c=32
I was wanting to see a URL of
http://foo.com?r=1&c=32
In that case, you can simply echo them out, once you're sure that $r,
and $c are actually integers.
I forgot to mention that above I did $r = intval($_GET[r])
!
Thanks, everyone!
echo "<a href='http://foo.com?r=$r&c=$c'>whatever</a>"
if not(sure they're integers, you could always
printf("<a href=\"http://foo.com?r=%d&c=%d\";>whatever</a>", $r, $c);
Alternatively you could $r = (int)$r;
or echo "<a href='http://foo.com?r="; . (int)$r . "&c=" . (int)$c .
"'>whatever</a>";
There's more than one way to do it.......
so was this the way to go?
//Make a thumbnail table of contents to display in the left sidebar
while ($sidebar = mysql_fetch_assoc($sidebar_result)) {
$sidebar_thumbnails[] = "<a class='img-link'
href='{$_SERVER['PHP_SELF']}?p=%p&c={$sidebar['art_id']}, urlencode($p)'
title=\"{$sidebar['art_title']}\"><img class='sidebar-img'
src='{$image_dir}{$sidebar['art_thumbnail']}' width='50' height='60'
border='0' alt=\"{$sidebar['art_title']}\" /></a>";
}
?
Thanks in advance!

Hi,
If I want to make a link to a URL which includes some GETs can I just
do:
<a href='{$_SERVER['PHP_SELF']}?p={$p}&c={$s}' ... etc etc
or must I escape the ampersand somehow?
TIA,
