[PHP] uploading...

[BBC]

hi all...
I have the problem about this syntax:

   $db->query("INSERT INTO `products`
       (`code`,`size`,`description`,`material`,`ads`,`price`,`new`,`categorynr`)
   VALUES
       ('$code',
        '$size',
        '$description',
        '$material',
        '$ads',
        '$price',
        '$new',
        '$categorynr')");

the syntax above could work properly in my computer which using PHP 4.1.1
but the problem is when I publish it the server where I hosted couldn't run 
such syntax (server uses PHP 4.4.2
I don't know why. is any one can help me?
please tell me the right syntax...

Best Regard
