In this tutorial we will create a
Get Last Inserted ID using SQLite3. This code will retrieve the last entry that have been store in the database when the user submit the form data. The code use PHP
POST method to launch a specific function to get the last id using
lastInsertRowID() and display it by adding the id in the WHERE clause. This a free program, you can apply this to your system as your own.
We will be using
SQLite that 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.
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 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
Open your any kind of text editor(notepad++, etc..). Then just copy/paste the code below then name it
conn.php.
<?php
$conn=new SQLite3
('db/db_member') or
die("Unable to open database!"); $query="CREATE TABLE IF NOT EXISTS `member`(mem_id INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL, firstname TEXT, lastname TEXT, address TEXT)";
?>
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.

<div class="col-md-4">
<form method="POST">
<div class="form-group">
<label>Firstname</label>
<input type="text" class="form-control" name="firstname" required="required"/>
</div>
<div class="form-group">
<label>Lastname</label>
<input type="text" class="form-control" name="lastname" required="required"/>

<div class="form-group">
<label>Address</label>
<input type="text" class="form-control" name="address" required="required"/>
</div>
<center><button class="btn btn-primary" name="insert" >Insert</button></center>
</form>
<br />
<?php include'insert.php'?>
</div>
<div class="col-md-8">
<table class="table table-bordered">
<thead class="alert-info">
<tr >
<th>Firstname</th>
<th>Lastname</th>
<th>Address</th>
</tr>
</thead>
<tbody>
<?php
require'conn.php';
$query=$conn->query("SELECT * FROM `member`") or
die("Failed to fetch row!"); while($fetch=$query->fetchArray()){
echo"<tr><td>".$fetch['firstname']."</td><td>".$fetch['lastname']."</td><td>".$fetch['address']."</td></tr>";
}
?>
</tbody>
</table>
</div>
</div>
</body>
</html>
Creating the Main Function
This code contains the main function of the application. This code will display the last inserted data when submitted. To do this just copy and write these block of codes as shown below inside the text editor, then save it as
insert.php.
<?php
require_once'conn.php';
if(ISSET($_POST['insert'])){ $firstname=$_POST['firstname'];
$lastname=$_POST['lastname'];
$address=$_POST['address'];
$query="INSERT INTO `member` (firstname, lastname, address) VALUES('$firstname', '$lastname', '$address')";
$id=$conn->lastInsertRowID();
$q=$conn->query("SELECT * FROM `member` WHERE `mem_id`='$id'") or
die("Failed to fetch row!"); $fetch=$q->fetchArray();
echo "<center><label>You have inserted <span class='text-danger'>".$fetch['firstname']." ".$fetch['lastname']."</span> has a new member.</label></center>";
}
?>
