ExpressJS: How to send data to URL - node.js

Question

I have a post request which redirects to a new route as you can see
//POST login
app.post('/login', urlencodedParser, function(req,res){
userLogin(req.body, function(response){
if(response == true){
//Activate player login in db
loginPlayerDB(req.body.username);
getPlayerId(req.body.username, function(id){
res.redirect(req.baseUrl + '/:id/profile');
});
} else{
res.send(500, "Username or Password is incorrect");
}
})
});
This function gets called
function getPlayerId(username, callback){
let sql = "SELECT PlayerId FROM users WHERE Username = (?)";
var values = [username];
db.query(sql, values, function(err, result, fields){
if(err){
console.log(err);
} else{
return callback(result);
}
})
}
It redirects to this route
app.get('/:id/profile', function(req,res){
res.render('profile/profile');
})
Everything works great except the URL on the new page is
http://localhost:3000/:id/profile
When it should be something like
http://localhost:3000/6/profile
If the player has an id of 6. How do I fix this
//Solution.
Thank you to MadWard for the help. My mistake was that in my getPlayerId function, I return result, which is an array, instead of result[0].PlayerId in order to get the specific id I was looking for

You are literally redirecting to /:id/profile. This is a string, it is fixed, and will always be '/:id/profile'.
What you want to do instead is, using template strings:
getPlayerId(req.body.username, function(id){
res.redirect(`${req.baseUrl}/${id}/profile`);
});
Using normal string concatenating like you were doing:
getPlayerId(req.body.username, function(id){
res.redirect(req.baseUrl + '/' + id + '/profile');
});
