Delete MySQLi Data In Modal Using PHP


In this tutorial, we will create a Delete MySQLi Data In Modal using PHP. This code can delete MySQLi data when the user clicks the delete button. The system uses a Bootstrap modal to launch a prompt message that needs confirmation to delete MySQLi data using the DELETE query. This a user-friendly program. Feel free to modify and use it for your system.

We will be using PHP as a scripting language and interpreter, mainly used on any web server, including xamp, wamp, etc. It is being used to any reputable websites because of the modern approach as its today.

Getting Started:

First, you have to download & install XAMPP or any local server that runs PHP scripts. Here’s the link for the 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/.

Creating Database

Open your database web server then create a database name in it db_delete_modal; after that, click Import, then locate the database file inside the folder of the application then click ok.

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
    $conn = mysqli_connect('localhost', 'root', '', 'db_delete_modal') or die(mysqli_error());
    if(!$conn){
        die("Error: Failed to connect to database");
    }
?>

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 your text editor, then save it as index.php.

Creating PHP Query

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

<?php
    require_once 'conn.php';
 
    $firstname = $_POST['firstname'];
    $lastname = $_POST['lastname'];
    $address = $_POST['address'];
 
    mysqli_query($conn, "INSERT INTO `member` VALUES('', '$firstname', '$lastname', '$address')") or die(mysqli_error());
 
    header("location: index.php");
?>

Creating the Main Function

This code contains the main function of the application. This code will delete a MySQLi data when the button is clicked. To make this just copy and write these block of codes below inside the text editor, then save it as delete.php

<?php
    require_once 'conn.php';
 
    if(ISSET($_REQUEST['mem_id'])){
        $id=$_REQUEST['mem_id'];
        mysqli_query($conn, "DELETE FROM `member` WHERE `mem_id`='$id'") or die(mysqli_error());
        header("location:index.php");
    }
?>
