This time, I will teach you how to Insert Data Into Database Using PHP and MySQLi. In this tutorial it will demonstrate to you on how to Insert Data Into Database with the use of insert query statement in PHP and MySQLi.
Below are following step by step guide on how to Insert Data Into Database Using PHP and MySQLi.
Lets Begin:
First Step: Create a MySQL Database and name it “userdb“.
Second Step: Do the following code for creating a table in the database that you have created.
[mysql]
CREATE TABLE `userdb`.`tbluser` (
`UserID` INT NOT NULL AUTO_INCREMENT PRIMARY KEY ,
`Name` VARCHAR( 30 ) NOT NULL ,
`Username` VARCHAR( 30 ) NOT NULL ,
`Pass` VARCHAR( 90 ) NOT NULL
) ENGINE = INNODB;
[/mysql]Third Step: Create a .php file and name it “index.php“.
Fourth Step: Do the following code for the html view of a form.
[php]
<html>
<title>Insert Data Into Database Using PHP and MySQLi</title>
<head>
<h1 align="center">Add New User</h1>
</head>
<body>
<div id="box">
<div class="column"></div>
<div class="column"><form id="main" class="form" action="index.php " method="POST"><label class="first-column ">Name:</label>
<div class="second-column"></div>
<div class="clear"></div>
<label class="first-column ">Username:</label>
<div class="second-column"></div>
<div class="clear"></div>
<label class="first-column ">Password:</label>
<div class="second-column"></div>
<div class="clear"></div>
<div class="first-column "></div>
<div class="second-column"><button class="btn" name="save" type="submit">Save</button></div>
</form>
</div>
<div class="column"></div>
</div>
</body>
</html>
[/php]Fifth Step: Create a CSS Style for the layout of the form.
[css]
#box{
width: 100%;
}
.column {
width: 33.33%;
display: inline-block;
}
.form{
padding: 2px;
width: 100%;
display: inline-block;
}
.first-column {
display: inline-block;
width: 100px;
height: 2px;
margin: 2px;
position: inherit;
}
.second-column{
display: inline-block;
width: 150px;
height: 25px;
margin: 1px;
padding: 0px;
position: inherit;
}
.btn{
width: 50px;
height: 40px;
margin: 2px;
float: left;
}
.c{
c: left;
height: 15px;
}
[/css]<div id="box">
<div class="column">
<form id="main" class="form" action="index.php " method="POST">Sixth Step: Create a script for inserting data into database.<p></p>
</form></div></div>[php]
<?php
$server="localhost";
$userid ="root";
$Password = "";
$myDB = "userdb";
$con = mysqli_connect($server,$userid,$Password,$myDB);
if (mysqli_connect_errno()) {
# code...
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
if (isset($_POST['save'])) {
# code...
$name = $_POST['name'];
$username = $_POST['username'];
$pass = $_POST['pass'];
$sqli = "INSERT INTO `tbluser` (`UserID`, `Name`, `Username`, `Pass`) VALUES (null,'{$name}','{$username}','{$pass}')";
$res = mysqli_query($con,$sqli);
if ($res) {
# code...
echo "New Data has been save in the database.";
}
mysqli_close($con);
}
?>

Frequently Asked Questions
How does this PHP project work?
Built with vanilla PHP (no framework) and MySQL backend. Standard structure: form HTML, PHP script handlers, MySQL via PDO or mysqli, sessions for auth, Bootstrap for responsive layout. Ready to extend for BSIT capstone scope.
What PHP and MySQL versions does this project require?
Most projects in this batch run on PHP 7.4 to PHP 8.2 with MySQL 5.7+ or MariaDB 10+. A few older projects need PHP 5.6 (deprecated, use XAMPP 7.x). To run: install XAMPP / WAMP / Laragon, extract project to htdocs, import the included .sql file via phpMyAdmin, edit the connection file (usually config.php or db_connect.php) with your DB credentials, browse to the project URL in your browser.
How do I set up the database for this PHP project?
Open phpMyAdmin (http://localhost/phpmyadmin/ on XAMPP), create a new empty database with the name specified in the project’s config.php. Click the Import tab, choose the included .sql file, click Go. Then edit config.php (or includes/connection.php) with: ‘localhost’, your MySQL username (usually ‘root’), your MySQL password (usually blank for XAMPP), and the database name.
Can I use this PHP project for a BSIT capstone or thesis?
Yes, but extend it. A bare CRUD app is too narrow for full capstone scope. Add: user roles via session checks, reports/dashboards (Chart.js + AJAX), PDF exports (TCPDF library), email notifications (PHPMailer), real domain extension (analytics, audit log, multi-branch support). Pair with Chapter 1-5 documentation matching your panel’s rubric.
Why am I getting ‘connection error’ or ‘undefined function mysqli_connect’?
Three common PHP issues: (1) Connection error: Apache + MySQL services not running in XAMPP control panel, OR database name in config.php does not match what you created in phpMyAdmin. (2) ‘undefined function mysqli_connect’: MySQL extension not enabled, in php.ini uncomment extension=mysqli (then restart Apache). (3) ‘No such file or directory’: MySQL socket path wrong, use 127.0.0.1 instead of localhost in the connection string.
Where can I find more PHP projects with source code?
Browse the PHP Projects hub for the full library (300+ vanilla PHP systems). For modern PHP MVC alternatives see Laravel Projects (74 systems) or CodeIgniter Projects (32 systems). For BSIT-focused capstone idea lists see 150 Best Capstone Project Ideas.
