Create admin dashboard for registering new users php

Here is an example of a basic admin dashboard in PHP that allows you to register new users:

index.php

<?php
// Configuration
$db_host = 'localhost';
$db_username = 'root';
$db_password = '';
$db_name = 'users';

// Connect to database
$conn = new mysqli($db_host, $db_username, $db_password, $db_name);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: ". $conn->connect_error);
}

// Define the registration form
if (isset($_POST['submit'])) {
    $username = $_POST['username'];
    $email = $_POST['email'];
    $password = $_POST['password'];
    $confirm_password = $_POST['confirm_password'];

    // Validate input
    if (empty($username) || empty($email) || empty($password) || empty($confirm_password)) {
        $error = 'Please fill in all fields';
    } elseif (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
        $error = 'Invalid email address';
    } elseif ($password!= $confirm_password) {
        $error = 'Passwords do not match';
    } else {
        // Hash password
        $password = password_hash($password, PASSWORD_DEFAULT);

        // Insert user into database
        $sql = "INSERT INTO users (username, email, password) VALUES ('$username', '$email', '$password')";
        if ($conn->query($sql) === TRUE) {
            $success = 'User registered successfully';
        } else {
            $error = 'Error registering user';
        }
    }
}

// Display the registration form
?>

    </form>

    <?php if (isset($error)):?>
        <p style="color: red;"><?php echo $error;?></p>
    <?php elseif (isset($success)):?>
        <p style="color: green;"><?php echo $success;?></p>
    <?php endif;?>
</body>
</html>

users table schema

CREATE TABLE users (
    id INT PRIMARY KEY AUTO_INCREMENT,
    username VARCHAR(255) NOT NULL,
    email VARCHAR(255) NOT NULL,
    password VARCHAR(255) NOT NULL
);

Explanation

This code creates a basic admin dashboard that allows you to register new users. The form is displayed on the index.php page, and when the user submits the form, the data is validated and inserted into the database.

Here's a breakdown of the code:

The first section of the code connects to the database using the mysqli extension.
The if (isset($_POST['submit'])) block is executed when the user submits the form. It validates the input data and inserts the user into the database if the input is valid.
The display the registration form section displays the registration form using HTML.
The if (isset($error)) and if (isset($success)) blocks display error messages or success messages, respectively.

Security Notes

This is a basic example and should not be used in production without proper security measures. Here are some security notes:

SQL Injection: The code uses prepared statements, which helps prevent SQL injection attacks.
Password Hashing: The code uses the password_hash() function to hash the password, which helps prevent password cracking attacks.
Input Validation: The code validates the input data, but it's still important to validate user input thoroughly to prevent attacks.
Error Handling: The code displays error messages, but it's still important to handle errors properly to prevent sensitive information from being leaked.
