INSERT INTO for PHP is not inserting data into my database users table on MySQL workbench. When click the submit button it just goes to a blank submit.php file when it's suppose to redirect to the login page once a user finishes inputting their information. Note: I'm still in the process of learning PHP, so any help would be appreciated. My code for my registration page(landingTwo) and my submit.php page is below:
landingTwo.php
<!DOCTYPE html>
<?php
require_once('db-include/config.php');
require_once('db-include/session.php');
if (!isset($_SESSION['needs']))
header("location: /index.php");
?>
<html lang="en">
<body>
<form action="db-include/submit.php" method="POST">
<input class="form-control form-control-lg" name="first_name" type="text" style="

require_once('session.php');
$first_name = $_POST['first_name'];
$last_name = $_POST['last_name'];
$email = $_POST['email'];
$city = $_POST['city'];
$state_name = $_POST['state_name'];
$passwd = $_POST['passwd'];
// Hash the password for security
$hashed_password = password_hash($passwd, PASSWORD_DEFAULT);
$sql = "INSERT INTO users (first_name, last_name, email, city, state_name, passwd, date_added) VALUES (?, ?, ?, ?, ?, ?, NOW())";
$stmt = $conn->prepare($sql);
$stmt->bind_param("ssssss", $first_name, $last_name, $email, $city, $state_name, $hashed_password);
if ($stmt->execute()) {
header("Location: /login.php"); // Redirect to the login page after successful registration
} else {
echo "Error: " . $sql . "<br>" . $conn->error;
}
$stmt->close();
$conn->close();
?>
I expect the form if successful to go to the login.php file when successfully executed and inserted into the users database.
