Problem passing strings

[Anon]

I'm extracting usernames from a db table, and displaying them in a table. After each name is a href image (questionmark.gif). When clicked, it passes the username, stored in $row[0] to another php file. Annoyingly, if the username has a space in it, eg. 'phil jones', only the 'phil' portion is passed in the $viewer variable:

echo "$row[0]";
echo "<a href=/lookup.php?viewer=$row[0]>
<img src=/questionmark.gif border=0></a>";

Does anyone have any suggestions?
Thanks,
Pete

Pete -
You can try converting all the spaces to underscores before passing them, using something like this:
$row[0] = str_replace(" ", "_", $row[0]);

then you can convert them back to spaces in the other PHP file:
$viewer = str_replace("_", " ", $viewer);

keep in mind that if the username actually has an underscore in it, it will be converted to a space using this code, so you may have to use a different character than an underscore as the replace character (maybe %20) ?

good luck.

come to think of it, you can also use
urlencode ($row[0]);
before passing it to the other file.

in the other file just use:
urldecode ($viewer);

this should work, and is much more comprehensive than my previous response.
