SQLite Delete Data With Modal Dialog PHP Source Code

In this tutorial we will create a SQLite Delete Data With Modal Dialog using PHP. This code will delete a table row in SQLite database with a modal prompt when user click the delete button. The code use jQuery Modal to call specific request that will launch a modal dialog before dynamically delete a row in the SQLite database and by sending a primary key as a request in the DELETE query. 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

And, this is the link for the bootstrap that i used for the layout design

Installing SQLite Browser
We will now then install the SQLite data viewer, here's the link for the DB Browser for SQLite

Setting Up SQLite

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

  1. Open localhost server folder XAMPP, etc and locate php.ini.
  2. Open php.ini and enable sqlite3 by removing the semicolon in the line.
  3. 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.

  1. <?php
  2. $conn=new SQLite3('db/db_member') or die("Unable to open database!");
  3. $query="CREATE TABLE IF NOT EXISTS `member`(mem_id INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL, firstname TEXT, lastname TEXT, address TEXT)";
  5. $conn->exec($query);
  6. ?>

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.

  1. <!DOCTYPE html>
  2. <html lang="en">
  3. <head>
  4. <meta charset="UTF-8" name="viewport" content="width=device-width, initial-scale=1" />
  5. <link rel="stylesheet" type="text/css" href="css/bootstrap.css" />
  6. </head>
  7. <body>
  8. <nav class="navbar navbar-default">
  9. <div class="container-fluid">

Creating the SQLite Query

This code contains the SQLite query of the application. This code will store the data inputs to the database server. To do this just copy and write these block of codes as shown below inside the text editor, then save it as insert.php

  1. <?php
  2. require_once'conn.php';
  3. if(ISSET($_POST['insert'])){
  4. $firstname=$_POST['firstname'];
  5. $lastname=$_POST['lastname'];
  6. $address=$_POST['address'];
  9. $query="INSERT INTO `member` (firstname, lastname, address) VALUES('$firstname', '$lastname', '$address')";
  11. $conn->exec($query);
  13. header("location:index.php");
  14. }
  15. ?>

Creating the Main Function

This code contains the main function of the application. This code will dynamically delete the table row with a modal dialog when the button is clicked. To do this just copy and write these block of codes as shown below inside the text editor, then save it as delete.php.

  1. <?php
  2. require_once'conn.php';
  4. if(ISSET($_REQUEST['mem_id'])){
  5. $mem_id=$_REQUEST['mem_id'];
  7. $conn->query("DELETE FROM `member` WHERE `mem_id`='$mem_id'") or die("Failed to delete a row!");
  8. header('location:index.php');
  9. }
  10. ?>
