Inserting and showing data from database in PHP & MySQL
Good day everyone! Today I am going to teach you some basic knowledge about on how to insert data in database in PHP as well as showing the data inserted on it.
This tutorial has a big help for beginners for starting up their dynamic websites.
Ok! Let’s start our tutorial.
First, create an “index.php” file then put the following codes.
[php]
<p style="padding-left: 60px;"><html></p>
<p style="padding-left: 60px;"><head></p>
<p style="padding-left: 60px;"><title>ITSourcecode</title></p>
<p style="padding-left: 60px;"></head></p>
<p style="padding-left: 60px;"><body></p>
<p style="padding-left: 60px;"><h1>Add Name Here:</h2></p>
<p style="padding-left: 60px;"><form method=”post” action=”insert.php”></p>
<p style="padding-left: 60px;"><input type=”text” name=”name” /><br></p>
<p style="padding-left: 60px;"><input type=”submit” value=”Save” /></p>
<p style="padding-left: 60px;"></form></p>
<p style="padding-left: 60px;"></body></p>
<p style="padding-left: 60px;"></html></p>
<p style="padding-left: 60px;">[/php]</p>Output:
Second, create a database. Name it as “mydatabase”.
Then create table, name it as “mydata”, then put the following columns:
my_id = primary keymy_name = textJust like this:
Then create a “connect.php” file then insert the following codes.
Then create an “insert.php” file, then put the following codes.
[php]
<?php
Include ‘connect.php’;
if (isset($_POST[‘name’])) {
$name = $_POST[‘name’];
$insert_name = $mysqli->query(“INSERT INTO mydata (my_name) VALUES (‘$name’)”);
if ($insert_name) {
header(“Location: index.php”);
}
}
?>
<p style="padding-left: 60px;">[/php]</p>Now, try to insert data.
Now, let’s show all the data inserted in the database.
On the index file, put the following codes below after the form.
[php]
<php
$mydata = $mysqli->query(“SELECT * FROM mydata”);
While ($my_data = $mydata->fetch_assoc()) {
Echo ‘ID: ’ . $my_data[‘my_id’] . ‘Name: ’ . $mydata[‘my_name’]. ‘<br>’;
}
?>
<p style="padding-left: 60px;">[/php]</p>
Output:
Then try to insert another data.
That’s all and thank you.
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.
