Bootstrap and php and add a new admin user

Here's a step-by-step guide on how to add a new admin user using Bootstrap and PHP:

Prerequisites:

You have a PHP script that connects to your database and has a function to add a new user.
You have a Bootstrap-based HTML file that displays a form to add a new user.
You have a database table named users with columns id, username, password, email, and role (with admin as the default role).

Step 1: Create the HTML form using Bootstrap

Create a new HTML file (e.g., add-admin-user.html) and add the following code:

<!DOCTYPE html>
<html>
<head>
    <title>Add Admin User</title>
    <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css">
</head>
<body>
    <div class="container">
        <h1 class="text-center">Add Admin User</h1>
        <form action="add-admin-user.php" method="post">
            <div class="form-group">
                <label for="username">Username:</label>
                <input type="text" class="form-control" id="username" name="username" required>
            </div>
            <div class="form-group">
                <label for="password">Password:</label>
                <input type="password" class="form-control" id="password" name="password" required>
            </div>
            <div class="form-group">
                <label for="email">Email:</label>
                <input type="email" class="form-control" id="email" name="email" required>
            </div>
            <button type="submit" class="btn btn-primary">Add User</button>
        </form>
    </div>
</body>
</html>

This form has three input fields: username, password, and email. The form action is set to add-admin-user.php, which is the PHP script that will handle the form submission.

Step 2: Create the PHP script to add a new admin user

Create a new PHP file (e.g., add-admin-user.php) and add the following code:

<?php
// Connect to the database
$conn = mysqli_connect("localhost", "username", "password", "database_name");

// Check connection
if (!$conn) {
    die("Connection failed: ". mysqli_connect_error());
}

// Get the form data
$username = $_POST['username'];
$password = $_POST['password'];
$email = $_POST['email'];

// Hash the password
$password_hash = password_hash($password, PASSWORD_DEFAULT);

// Add the new user to the database
$query = "INSERT INTO users (username, password, email, role) VALUES ('$username', '$password_hash', '$email', 'admin')";
$result = mysqli_query($conn, $query);

// Check if the query was successful
if (!$result) {
    die("Error adding user: ". mysqli_error($conn));
}

// Close the database connection
mysqli_close($conn);

// Redirect to a success page
header("Location: success.php");
exit;
?>

This PHP script connects to the database, gets the form data, hashes the password using the password_hash() function, and adds the new user to the users table with the admin role. If the query is successful, it redirects the user to a success page.

Step 3: Create the success page

Create a new HTML file (e.g., success.php) and add the following code:

<!DOCTYPE html>
<html>
<head>
    <title>Success</title>
    <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css">
</head>
<body>
    <div class="container">
        <h1 class="text-center">User added successfully!</h1>
        <p>You can now log in with your new admin credentials.</p>
    </div>
</body>
</html>

This success page displays a message indicating that the user was added successfully.

Putting it all together

Save all the files in the same directory and open add-admin-user.html in a web browser. Fill out the form and submit it. The PHP script will add the new user to the database and redirect you to the success page.

Note: Make sure to replace the database connection details (e.g., localhost, username, password, database_name) with your actual database credentials.
