Tutorial: How to Insert Multiple Checkbox Data using PHP with Source Code

In this tutorial, we will create on How to Insert Multiple Checkbox Data using PHP. This code will allow the user to insert multiples checkbox data to the database server in one click. The code uses the MySQLi INSERT query to store a new entry in the MySQLi database, then when submitting the PHP script will compress the checkbox array by using implode to provide the data to the database as one entry. This a user-friendly program. Feel free to modify and use it for your system.

We will be using PHP as a scripting language that interprets in the webserver such as xamp, wamp, etc. It is widely used by modern website application to handle and protect user confidential information.

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_insert_multiple, 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_insert_multiple');
 
    if(!$conn){
        die("Error: Can't 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.

<!DOCTYPE html>
<html lang="en">
    <head>
        <meta charset="UTF-8" name="viewport" content="width=device-width, initial-scale=1"/>

        </div>
 
        <div class="col-md-8">
            <table class="table table-bordered">
                <thead class="alert-info">
                    <tr>
                        <th>Firstname</th>
                        <th>Lastname</th>
                        <th>Subjects</th>
                    </tr>
                </thead>
                <tbody>
                    <?php
                        require'conn.php';
                        $query=mysqli_query($conn, "SELECT * FROM `member`") or die(mysqli_error());
                        while($fetch=mysqli_fetch_array($query)){
                    ?>
                        <tr>
                            <td><?php echo $fetch['firstname']?></td>
                            <td><?php echo $fetch['lastname']?></td>
                            <td><?php echo $fetch['subject']?></td>
                        </tr>
                    <?php
                        }
                    ?>
                </tbody>
            </table>
        </div>
    </div>
</body>
</html>

Creating the Main Function

This code contains the main function of the application. This code will insert multiple 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 save.php.

<?php
    require_once 'conn.php';
 
    if(ISSET($_POST['save'])){
        $firstname = $_POST['firstname'];
        $lastname = $_POST['lastname'];
 
 
        $subjects=implode(", ", $_POST['subject']);
 
        mysqli_query($conn, "INSERT INTO `member` VALUES('', '$firstname', '$lastname', '$subjects')") or die(mysqli_error());
 
        header('location:index.php');
    }
 
 
?>
