Hi, Rory Rory Browne wrote:

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, --Jack -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
