Inserting Data into SQLite Database Using PHP PDO

Submitted by razormist on Wednesday, March 24, 2021 - 15:40.

In this tutorial we will create a Insert Data to SQLite Using PDO. PHP is a server-side scripting language designed primarily for web development. SQLite provides an interface for accessing the database. It includes class interfaces to the SQL commands. And also it allows you to create SQL functions and aggregate using PHP.

So Let's do the coding...

Getting started:

First you have to download & install XAMPP or any local server that run PHP scripts. Here's the link for XAMPP server https://www.apachefriends.org/index.html.

And this is the link for the jquery that i used in this tutorial https://jquery.com/.

Lastly, this is the link for the bootstrap that i used for the layout design https://getbootstrap.com/.

Installing SQLite Browser

We will now then install the SQLite data viewer, here's the link for the DB Browser for SQLite http://sqlitebrowser.org/.

Setting Up SQLite

First, we are going to enable SQLite 3 in our PHP.

Open localhost server folder XAMPP, etc and locate php.ini.
Open php.ini and enable sqlite3 by removing the semicolon in the line.
Save changes and Restart Server.

Creating the database connection

In your source code folder create a new folder naming "db". This will be the folder where your sqlite database file will be located. Then, open your any kind of text editor(notepad++, etc..). Then just copy/paste the code below then name it conn.php.

<?php
        $conn = new PDO('sqlite:db/db_member.sqlite3');
        
        $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
        
        $query = "CREATE TABLE IF NOT EXISTS member (mem_id INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL, firstname TEXT, lastname TEXT, address TEXT)";
        
        $conn->exec($query);
        
?>

Creating The Interface

This is where we will create a simple form for our application. To create the forms simply copy and write it into you text editor, then save it as index.php.

                <meta charset="UTF-8" name="viewport" content="width=device-width, initial-scale=1"/>

                                        $query = $conn->prepare("SELECT * FROM `member` ORDER BY `lastname` ASC");
                                        $query->execute();
                                        while($fetch = $query->fetch()){

                                        </div>
                                </form>
                        </div>
                </div>
        </div>
<script src="js/jquery-3.2.1.min.js"></script>
<script src="js/bootstrap.js"></script>
</body>
</html>

Creating the Main Function

This code contains the main function of the application. This code will store the data inputs to the SQLite database using PDO queries. To do this just copy and write these blocks of codes as shown below inside the text editor and save it as save_member.php.

<?php
        require_once 'conn.php';
        
        
        if(ISSET($_POST['save'])){
                $firstname = $_POST['firstname'];
                $lastname = $_POST['lastname'];
                $address = $_POST['address'];
                
                $query = "INSERT INTO member (firstname, lastname, address) VALUES (:firstname, :lastname, :address)";
                
                $stmt = $conn->prepare($query);
        
                $stmt->bindParam(':firstname', $firstname);
                $stmt->bindParam(':lastname', $lastname);
                $stmt->bindParam(':address', $address);
        
                $stmt->execute();
                
                header('location: index.php');
                
                $conn = null;
        }
?>

Great tutorial

Thanks for showing PDO / SQLite tutorial. We have been learning PDO as provides better protection. Looking forward to possible future tuts on editing and deleting with PDO / SQLite. Thank you again, Susan
