Issue updating SQL variables - php

Question

I have been attempting to update my SQL database which worked 100% with just updating the password. Once I try to update another variable in my database it just refreshes the page! I have been trying and looking at examples for hours, any help would be greatly appreciated. I believe the error is somewhere in my SQL code along with binding the variables to the prepared statement line. Other than that I have no idea where to start. So any direction would help as well!
PHP:
<?php
// Initialize the session
session_start();
// Check if the user is logged in, if not then redirect to login page
if(!isset($_SESSION["loggedin"]) || $_SESSION["loggedin"] !== true){
header("location: login.php");
exit;
}
// Include config file
require_once "config.php";
// Define variables and initialize with empty values
$new_password = $confirm_password = "";
$new_password_err = $confirm_password_err = "";
$new_discordusername = $_SESSION["DiscordUsername"];
$new_steamid = $_SESSION["steamid"];
// Processing form data when form is submitted
if($_SERVER["REQUEST_METHOD"] == "POST"){
// Validate new password
if(empty(trim($_POST["new_password"]))){
$new_password_err = "Please enter the new password.";
} elseif(strlen(trim($_POST["new_password"])) < 6){
$new_password_err = "Password must have atleast 6 characters.";
} else{
$new_password = trim($_POST["new_password"]);
$new_discordusername = trim($_POST["new_discord"]);
$new_steamid = trim($_POST["new_steam"]);
}
// Validate confirm password
if(empty(trim($_POST["confirm_password"]))){
$confirm_password_err = "Please confirm the password.";
} else{
$confirm_password = trim($_POST["confirm_password"]);
if(empty($new_password_err) && ($new_password != $confirm_password)){
$confirm_password_err = "Password did not match.";
}
}
// Check input errors before updating the database
if(empty($new_password_err) && empty($confirm_password_err)){
// Prepare an update statement
$sql = "UPDATE users SET
password = ?,
steamid = ?
WHERE id = ?";
if($stmt = mysqli_prepare($link, $sql)){
// Set parameters
$param_password = password_hash($new_password, PASSWORD_DEFAULT);
$param_id = $_SESSION["id"];
$param_discordusername = $new_discordusername;
$param_steamid = $new_steamid;
// Bind variables to the prepared statement as parameters
mysqli_stmt_bind_param($stmt, "ssi", $param_password, $param_steamid, $param_id);
// Attempt to execute the prepared statement
if(mysqli_stmt_execute($stmt)){
// Password updated successfully. Destroy the session, and redirect to login page
session_destroy();
header("location: login.php");
exit();
} else{
echo "Oops! Something went wrong. Please try again later." + mysqli_error($link);
}
// Close statement
mysqli_stmt_close($stmt);
}
}
// Close connection
mysqli_close($link);
}
?>
