Добрый день!

    echo 'Contents of $_FILES:<br/><pre>'.print_r($_FILES, true).'</pre>';
    $uploaddir = $_SERVER['DOCUMENT_ROOT'].DIRECTORY_SEPARATOR.'upload'.DIRECTORY_SEPARATOR .'default'.DIRECTORY_SEPARATOR ;
$uploadfile = $uploaddir . basename($_FILES['my-pic']['name']);
if (move_uploaded_file($_FILES['my-pic']['tmp_name'], $uploadfile)) {
        print "Закачено успешно!!";
   if( mysql_query("insert into gallary (`foto`, `cat`)values('".$uploadfile."', '".$_FILES['my-pic']['cat']."')")){  
} else {
        print "EPIC FAIL";
}
}

папка /upload/default/ существует, права 777

18 строка это move_uploaded_file($_FILES['my-pic']['tmp_name'], $uploadfile)

где я допустил ошибку?

[DarkGuy]

все решил!

$_SERVER['DOCUMENT_ROOT'].'/upload/default/'
