Since nobody else has spotted the issue, I'll post it for you. The reason you're prepare() is failing is because you're trying to use a MySQL Reserved Word. The word desc is a reserved word in MYSQL, which means you need to wrap it in backticks like this:

$statement= $db->prepare("insert into uploaddetails(idnum,title,`desc`,author,tags,file) values(?,?,?,?,?,?)");

It also helps to use proper practice when inserting into a database/using prepared statements.

$statement= $db->prepare("insert into uploaddetails(idnum,title,`desc`,author,tags,title) values(?,?,?,?,?,?)");

if($statement !== FALSE) {
    // do the binds...etc
}

Notes

file is also a reserved word, I don't know what your actual file columns name is, so keep that in mind.
