[Resolved] Quick question - passing variables in URL

lizzyd

Sorry everyone - i know this is going to be simple, but none of the search terms i can think of to find it are bearing fruit.....

I'm having problems with the following line:

<td><a href="<?php echo "http://www.xyz.co.uk/abc.php?Town=" . $Town . "&County=" . $County . "&s=2" ?>">Click here to view luxury hotels first</a></td>

Basically, on the previous page, the user has either selected a Town (therefore the Town has been passed through in the URL), or a County (in which case just the County is passed through in the URL).

If the former is true I don't want any mention of County in the code above, whereas if it's the latter, I don't want any mention of Towns.

So my problem is - is there a simple way of writing either/or in the URL?? because I don't want my links to end up with loads of unnecessary variables. (The code above works fine at the moment by the way. It's just that I heard that for search engines it's a case of the less variables, the better!)

I'd be very grateful for any ideas!

hi!
this is one easy possibility to solve this:

<?php
$link = "http://www.xyz.co.uk/abc.php?";
  if ($Town != "")
    $link .= "Town='" . $Town . "'&";
  else if ($County != "")
    $link .= "County='" . $County . "'&";
  $link .= "s=2";
echo "<td><a href='" . $link . "'>Click here to view luxury hotels first</a></td>";
?>

Cheers LarsLai! I was reckoning I would have to go along those kind of lines - just thought i'd better check there weren't any neat little symbols i didn't know about before I attempted it. Thanks very much for getting back to me - I've got it working perfectly now!!
