Open the config.php file and insert the following code.
Be sure to include this configuration file in all your PHP scripts using the include_once() function. This file contains the essential database connection setup, and without it, you won’t be able to perform any database operations.
PHP + Bootstrap CRUD Tutorial Overview
-
CRUD: Create, Read, Update, Delete operations on a database table.
-
Database: MySQL table
users. -
Front-end: Bootstrap 3 + jQuery.
-
Back-end: PHP with MySQLi.
1. Database Setup
Run this SQL query to create the users table:
CREATE TABLE `users` (
`id` int(11) NOT NULL AUTO_INCREMENT PRIMARY KEY,
`username` varchar(64) NOT NULL,
`useremail` varchar(128) NOT NULL,
`address` varchar(150) NOT NULL,
`userphone` varchar(24) NOT NULL,
`dt` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP
) ENGINE=MyISAM DEFAULT CHARSET=utf8mb4;
Note: Added AUTO_INCREMENT PRIMARY KEY to id for proper record management.
2. connect_db.php
<?php
$servername = 'localhost';
$username = 'root';
$password = '';
$dbname = 'employee';
$conn = mysqli_connect($servername, $username, $password, $dbname);
if (!$conn) {
die("ERROR: Could not connect. " . mysqli_connect_error());
}
?>
3. insert_data.php
<?php
include_once 'connect_db.php';
$success = "";
if (isset($_POST['add'])) {
$username = mysqli_real_escape_string($conn, $_POST['username']);
$useremail = mysqli_real_escape_string($conn, $_POST['useremail']);
$address = mysqli_real_escape_string($conn, $_POST['address']);
$phone = mysqli_real_escape_string($conn, $_POST['phone']);
$sql = "INSERT INTO users (username, useremail, address, userphone)
VALUES ('$username', '$useremail', '$address', '$phone')";
if (mysqli_query($conn, $sql)) {
$success = "New record created successfully!";
} else {
echo "Error: " . $sql . " " . mysqli_error($conn);
}
mysqli_close($conn);
}
?>
Security tip: Use mysqli_real_escape_string to prevent SQL injection.
4. index.php
<?php
include_once 'insert_data.php'; // Handles insert form submission
include 'connect_db.php';
$result = mysqli_query($conn, "SELECT * FROM users");
?>

Notes:
-
The Edit and Delete modals and their PHP handlers need to be implemented similarly for full CRUD functionality.
-
All form submissions use
POSTand should redirect or reloadindex.phpto reflect changes. -
The demo includes jQuery for checkbox selection and tooltips.
-
Use
htmlspecialchars()to avoid XSS vulnerabilities when displaying user input. -
For real applications, consider using prepared statements (
mysqli_prepare) for security.
