Ahh.. an easy one. Unless I'm mistaken (and it does happen more often than I'd like.. hah :) then you might want to ommit the first:
$media = mysql_fetch_assoc($media_result);
That's reading data into $media and then it happens again at the start of your while loop which is why you're only getting the second item.

Hi, all,
This might look like a mysql problem but I assure you it's my botching
the PHP which is the problem!
I'm building a part of a page with info from three tables: art, media
and media_art. Media_art is the intersection table. For every entry in
art there can be one or more entries in media.
art.art_id 1 has two entries in media_art:
Media_id art_id
3 2
5 2
I do this SQL, which in phpmyadmin returns the two names of media as
expected
SELECT media.media_name
FROM art, media_art, media
WHERE art.art_id = 1
AND art.art_id = media_art.art_id
AND media.media_id = media_art.media_id
Yet here's where I mess up. To see if I've got them in an array, I do:
$media = mysql_fetch_assoc($media_result);
while ($media = mysql_fetch_assoc($media_result))
~
asort($media);
foreach($media as $key => $val)
~ echo "key: $key value: $val <br />";
~
//end while $media = mysql_fetch_assoc($media_result)
and this returns only the name of the HIGHer number of the two (that is,
5).
What have I done wrong to echo out each name of the media associated
with this record? I'm trying, eventually, to echo it out in the age so
that it appears as
[art_id 1] comprises Ink, watercolor.
Thanks in advance,
Jack
