CodeIgniter

CodeIgniter is a powerful PHP framework with a very small footprint, built for developers who need a simple and elegant toolkit to create full-featured web applications.

This snippet gives you the simple and best explanation to insert data into a MySQL table.

This process contains three major steps.

View
Controller
Model

1. View

demo.php (place it in your view folder)

Which is the form where you will insert data

<html>
<head>
    <style>
        .container {
            width: 200px;
            height: 100px;
            padding: 200px;

        }
        label {
            padding: 10px;
        }

        .btn {
            float: right;
            padding: 5px;
        }
    </style>
</head>
<body class="container">
<form method='POST'>

    <label>Name</label>
    <input type="text" name="name"><br><br>

    <label>Number</label>
    <input type="text" name="number"><br><br>

 <input class="btn" type="submit" name="submitdemo" value="Submit">

</form>
</body>
</html>

2.Controller

Welcome.php(place it in your controller folder)

which will act as a bridge between your model and controller.

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class Welcome extends CI_Controller
{
    public function demo()
    {
        $this->load->model('levels');
        $name = $this->input->post('name');

        $number = $this->input->post('number');

        $data = array(
            'name' => $name,
            'number' => $number,
        );

        if (isset($_POST['submitdemo'])) {
            if (($name !== '')) {
                $this->levels->demo($data);
            } else {
                echo 'Please fill fields';
            }

        }
        $this->load->view('demo.php', $data);

    }
}
?>
3. Model
Levels.php(place it in your model folder)
Model will insert the data into table colected from form(demo.php)
through controller(Welcome.php)
<?php
class Levels extends CI_Model
{
    public function demo($data)
    {
        $this->load->database();
        $this->db->insert('demo', $data);
        echo 'Data inserted successfully';
    }
}
?>
MySql:
Run this query to create table in your database.

CREATE TABLE `demo` (
`id` int(11) NOT NULL,
`name` varchar(24) NOT NULL,
`number` varchar(10) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
