Why is this insert function not working?

Hello, I am having some issues with this function, it seems the query won't insert the data from the variables and I don't know why is this happening?

function insert(){
                $user = $_POST['user'];
                $pass = md5($_POST['pass']);
                $priv = "User";
                $mail = $_POST['mail'];
                $avatar = $_FILES['avatar']['name'];
                $submit = $_POST['submit'];

                $query = "INSERT INTO user(user,pass,priv,mail,avatar,date) VALUES(`$user`,`$pass`,`$priv`,`$mail`,`$avatar`,`$date`);";
                    $res = mysqli_query($con,$query) or die(mysqli_error($con));

I notice two things. The first is that you're using backquotes ( ` ) around your values. In MySQL, you'll need to use single quotes ( ' ) for literal values and backquotes for table/field names. The other is that you're wrapping the now() function in quotes when it should be unquoted.

Try this:

$query = "INSERT INTO `user` (`user`, `pass`, `priv`, `mail`, `avatar`, `date`) VALUES ('$user', '$pass', '$priv', '$mail', '$avatar', now());";

I'm reffering in the script to the MySQL now() function which supposed to show the time and date of the user and not a function named now() from php

Correct, the MySQL NOW() function needs to appear unquoted in your query, as per my previous example.
