MySQL End Tag?!?!? HELP!

[spiceydog]

So I have a php script that tells MySQL to post 30 lines but sometimes I don't want it to post all 30 lines and to stop at say the 15th line depending on something.
Here is what it looks like (Yes it's messy but it's what I need):
{
$query = "INSERT INTO albuminfo(track,
details,
dl,
user,
trackn,
genre,
theyear,
art,
artist,
albumname)
VALUES ('$track_1', '$details', '$dl', '$user', '$trackn', '$genre', '$theyear', '$art', '$artist', '$albumname'),
('$track_2', '$details', '$dl', '$user', '$trackn', '$genre', '$theyear', '$art', '$artist', '$albumname'),
('$track_3', '$details', '$dl', '$user', '$trackn', '$genre', '$theyear', '$art', '$artist', '$albumname'),
('$track_4', '$details', '$dl', '$user', '$trackn', '$genre', '$theyear', '$art', '$artist', '$albumname'),
('$track_5', '$details', '$dl', '$user', '$trackn', '$genre', '$theyear', '$art', '$artist', '$albumname'),
('$track_6', '$details', '$dl', '$user', '$trackn', '$genre', '$theyear', '$art', '$artist', '$albumname'),
('$track_7', '$details', '$dl', '$user', '$trackn', '$genre', '$theyear', '$art', '$artist', '$albumname'),
('$track_8', '$details', '$dl', '$user', '$trackn', '$genre', '$theyear', '$art', '$artist', '$albumname'),
('$track_9', '$details', '$dl', '$user', '$trackn', '$genre', '$theyear', '$art', '$artist', '$albumname'),
('$track_10', '$details', '$dl', '$user', '$trackn', '$genre', '$theyear', '$art', '$artist', '$albumname'),
('$track_11', '$details', '$dl', '$user', '$trackn', '$genre', '$theyear', '$art', '$artist', '$albumname'),
('$track_12', '$details', '$dl', '$user', '$trackn', '$genre', '$theyear', '$art', '$artist', '$albumname'),
('$track_13', '$details', '$dl', '$user', '$trackn', '$genre', '$theyear', '$art', '$artist', '$albumname'),
('$track_14', '$details', '$dl', '$user', '$trackn', '$genre', '$theyear', '$art', '$artist', '$albumname'),
('$track_15', '$details', '$dl', '$user', '$trackn', '$genre', '$theyear', '$art', '$artist', '$albumname'),
('$track_16', '$details', '$dl', '$user', '$trackn', '$genre', '$theyear', '$art', '$artist', '$albumname'),
('$track_17', '$details', '$dl', '$user', '$trackn', '$genre', '$theyear', '$art', '$artist', '$albumname'),
('$track_18', '$details', '$dl', '$user', '$trackn', '$genre', '$theyear', '$art', '$artist', '$albumname'),
('$track_19', '$details', '$dl', '$user', '$trackn', '$genre', '$theyear', '$art', '$artist', '$albumname'),
('$track_20', '$details', '$dl', '$user', '$trackn', '$genre', '$theyear', '$art', '$artist', '$albumname'),
('$track_21', '$details', '$dl', '$user', '$trackn', '$genre', '$theyear', '$art', '$artist', '$albumname'),
('$track_22', '$details', '$dl', '$user', '$trackn', '$genre', '$theyear', '$art', '$artist', '$albumname'),
('$track_23', '$details', '$dl', '$user', '$trackn', '$genre', '$theyear', '$art', '$artist', '$albumname'),
('$track_24', '$details', '$dl', '$user', '$trackn', '$genre', '$theyear', '$art', '$artist', '$albumname'),
('$track_25', '$details', '$dl', '$user', '$trackn', '$genre', '$theyear', '$art', '$artist', '$albumname'),
('$track_26', '$details', '$dl', '$user', '$trackn', '$genre', '$theyear', '$art', '$artist', '$albumname'),
('$track_27', '$details', '$dl', '$user', '$trackn', '$genre', '$theyear', '$art', '$artist', '$albumname'),
('$track_28', '$details', '$dl', '$user', '$trackn', '$genre', '$theyear', '$art', '$artist', '$albumname'),
('$track_29', '$details', '$dl', '$user', '$trackn', '$genre', '$theyear', '$art', '$artist', '$albumname'),
('$track_30', '$details', '$dl', '$user', '$trackn', '$genre', '$theyear', '$art', '$artist', '$albumname')";
}
{
mysql_query($query) or die('YOUR FIELD WAS TO LONG!');
exit;
} }

So what I want to happen is for if track_24 is empty then to stop there and not post anymore lines. Seems simple enough but I just can't figure it out! Please help!

Thanks,

instead of statically filling the values, loop through the tracks and build the insert. That way, once you're out of tracks, it'll stop.
