<?php session_start(); ?>
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">

</head>
<body>
    
    <div class="container">
        <div class="row justify-content-center">
            <div class="col-md-8">

                <?php 
                    if(isset($_SESSION['status']))
                    {
                        ?>
                            <div class="alert alert-warning alert-dismissible fade show" role="alert">
                            <strong>Hey!</strong> <?php echo $_SESSION['status']; ?>
                            <button type="button" class="btn-close" data-bs-dismiss="alert" aria-label="Close"></button>
                            </div>
                        <?php
                         unset($_SESSION['status']);
                    }
                ?>

                <div class="card mt-5">
                    <div class="card-header">
                        <h4>How to Insert Checkbox value into Database in php</h4>
                    </div>
                    <div class="card-body">

                        <form action="code.php" method="POST">
                            <div class="form-group mb-3">
                                <label>Name</label>
                                <input type="text" name="name" class="form-control" />
                            </div>
                            <div class="form-group mb-3">
                                <input type="checkbox" name="agree" value="I agree to it" /> I agree to this terms and condition.
                            </div>
                            <div class="form-group mb-3">
                                <button type="submit" name="save_checkbox" class="btn btn-primary">Save Data</button>
                            </div>
                        </form>

                    </div>
                </div>
            </div>
        </div>
    </div>

    <script src="https://code.jquery.com/jquery-3.5.1.js"></script>
    <script src="https://cdn.jsdelivr.net/npm/bootstrap@5.0.0-beta1/dist/js/bootstrap.bundle.min.js"></script>
</body>
</html>

Now, when you click on the Submit button, the <form> contains action="code.php" so, lets write the code:

Step 3: Create a code.php file and paste the below code to insert checkbox data in MySQL Database in php.

<?php
session_start();
$con = mysqli_connect("localhost","root","","phptutorials");

if(isset($_POST['save_checkbox']))
{
    $name = $_POST['name'];
    $agree = $_POST['agree'];

    $query = "INSERT INTO demo (name,agree) VALUES ('$name','$agree')";
    $query_run = mysqli_query($con$query);
    
    if($query_run)
    {
        $_SESSION['status'] = "Inserted Successfully";
        header("Location: index.php");
    }
    else
    {
        $_SESSION['status'] = "Not Inserted";
        header("Location: index.php");
    }
}
?>
