PHP - Update Multiple Table Row

Submitted by razormist on Friday, September 7, 2018 - 17:25.

In this tutorial we will create a Update Multiple Table Row using PHP. PHP is a server-side scripting language designed primarily for web development. Using PHP, you can let your user directly interact with the script and easily to learned its syntax. It is mostly used by a newly coders for its user friendly environment. 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/.

Creating Database

Open your database web server then create a database name in it db_row, after that click Import then locate the database file inside the folder of the application then click ok. tut1

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_row') 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.

<script src="js/bootstrap.js"></script>

Creating the Save Query

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

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

Creating the Update Row

This code contains the update query of the application. This code will update all the date in the row when the button update is clicked. To do that just copy and write this block of codes inside the text editor, then save it as update_row.php.

<?php
        require_once 'conn.php';
 
        $data = [];
        
        for($i=0; $i < count($_POST['mem_id']); $i++){
                $data[$_POST['mem_id'][$i]]['firstname'] = $_POST['firstname'][$i];
                $data[$_POST['mem_id'][$i]]['lastname'] = $_POST['lastname'][$i];
                $data[$_POST['mem_id'][$i]]['address'] = $_POST['address'][$i];
        }
        
        
        foreach($data as $key => $value){
                mysqli_query($conn, "UPDATE `member` SET `firstname` = '$value[firstname]', `lastname` = '$value[lastname]', `address` = '$value[address]' WHERE `mem_id` = '$key'");
        }
        
        header('location: index.php');
?>
