Nothing shows up when "echo" $_GET rows - php

Question

I'm trying to to create a users profile, it is suposed to get the id from the url, then get all the info from the user with that id.
<?php
session_start();
$userID = $_GET["id"];
$getUserNames = "SELECT * FROM users where id=$userID";
$result = $conn->query("getUserNames");
$row = mysqli_fetch_assoc($result);
if (isset($_GET["id"])) {
echo "<h1>";
echo $row["username"];
echo "</h1>";
echo "<p><b>Name: </b>";
echo $row["username"];
echo "</p>";
echo "<p><b>Password: </b>***** (<a href='#'>Change Password</a>)</p>";
} else {
if (isset($_SESSION["username"])) {
echo "<h1>";
echo $_SESSION["username"];
echo "</h1>";
echo "<p><b>Name: </b>";
echo $_SESSION["username"];
echo "</p>";
echo "<p><b>Password: </b>***** (<a href='#'>Change Password</a>)</p>";
} else {
echo "<p>You need to be logged in too see your profile!";
}
}?>
I get nothing from the echo and there is no error.
Please help!

Answer 1

You have an error at $conn->query("getUserNames"); which should be: $conn->query($getUserNames);
The complete new code with the fix looks like this:
<?php
session_start();
$userID = $_GET["id"];
$getUserNames = "SELECT * FROM users where id=$userID";
$result = $conn->query($getUserNames);
$row = mysqli_fetch_assoc($result);
if (isset($_GET["id"])) {
echo "<h1>";
echo $row["username"];
echo "</h1>";
echo "<p><b>Name: </b>";
echo $row["username"];
echo "</p>";
echo "<p><b>Password: </b>***** (<a href='#'>Change Password</a>)</p>";
} else {
if (isset($_SESSION["username"])) {
echo "<h1>";
echo $_SESSION["username"];
echo "</h1>";
echo "<p><b>Name: </b>";
echo $_SESSION["username"];
echo "</p>";
echo "<p><b>Password: </b>***** (<a href='#'>Change Password</a>)</p>";
} else {
echo "<p>You need to be logged in too see your profile!";
}
