<?
/* $song[0] is connected to my winamp. it shows the current song playing! */
?>

<? if(isset($_POST['form'])){?>

<?php function lynkfm_rate(){$select_data = "SELECT * FROM lynk_fm WHERE song='$song[0]' LIMIT 1";
$object = mysql_query($select_data) or die($MySQLError.mysql_error()); return $object; } $res99 = lynkfm_rate();
$show = mysql_fetch_object($res99); $new_score = $show->score + $score2 ; $new_vote = $show->votes + 1 ; ?>

<? if( $show->song = "$song[0]") {mysql_query("UPDATE lynk_fm SET score='$new_score', votes='$new_vote' ");
echo"new score: $show->score"; }
elseif ($show->song != "$song[0]") {mysql_query("INSERT INTO lynk_fm (id,date,artist,title,song,score,votes) VALUES ('', '$date_now', '".htmlspecialchars($artist)."', '".htmlspecialchars($title)."', '".htmlspecialchars($song[0])."', '$score2', '$votes') ") or die(mysql_error()); echo"$show->title"; }
else{echo "UPDATE DIDNT WORK! !!";}?>

The correct syntax for checking if values are equal in an if statment is  == 
if($value1 == $value2)
But that is going to make your update code run every time.

Also I'm not sure how your $song[0] is connected to the current song if there is a problem here then you will never actually find a match in the database to update.

[/quote] thanks for your reply :D the $song[0] request the current song on winamp, i have a code that wil print the current song, you can see it working here: http://lynkonline.atlas2wielers.nl/sc_song/now.php

I would set the mysql_query to a varible so it has a place to return any results.

$myquery = mysql_query(UPDATE ........);

then you can test $myquery for a true or false state 

also put the or die statement with the mysql error for more clues

ill check it out thanks fot the tips. can you find anything obviously wrong with the code?

i know its probably something very silly, but i just cant find out what it is...  ::)

[Lynk]

nah, nothing, not i get this error when i update...

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'WHERE artist='Busta Rhymes' AND title='Touch It (Remix part III)' SET score='10'' at line 1
