Download Codeigniter Project

In this step we will download the latest version of Codeigniter, Go to this link Download Codeigniter download the fresh setup of codeigniter and unzip the setup in your local system xampp/htdocs/ . And change the download folder name “demo”

Basic Configurations

Next we will set the some basic configuration on config.php file, so let’s go to application/config/config.php and open this file on text editor.

Set Base URL like this

$config['base_url'] = 'http://localhost/demo/';

Create Database With Table

In this step, we need to create database name demo, so let’s open your phpmyadmin and create the database with the name demo . After successfully create a database, you can use the below sql query for creating a table in your database.

CREATE TABLE users (
    id int(11) NOT NULL AUTO_INCREMENT COMMENT 'Primary Key',
    name varchar(100) NOT NULL COMMENT 'Name',
    email varchar(255) NOT NULL COMMENT 'Email Address',
    contact_no varchar(50) NOT NULL COMMENT 'Contact No',
    created_at varchar(20) NOT NULL COMMENT 'Created date',
    PRIMARY KEY (id)
  ) ENGINE=InnoDB DEFAULT CHARSET=latin1 COMMENT='datatable demo table' AUTO_INCREMENT=1;

  INSERT INTO users (id, name, email, contact_no, created_at) VALUES
  (1, 'Team', '[email protected]', '9000000001', '2019-01-01'),
  (2, 'Admin', '[email protected]', '9000000002', '2019-01-02'),
  (3, 'User', '[email protected]', '9000000003', '2019-01-03'),
  (4, 'Editor', '[email protected]', '9000000004', '2019-01-04'),
  (5, 'Writer', '[email protected]', '9000000005', '2019-01-05'),
  (6, 'Contact', '[email protected]', '9000000006', '2019-01-06'),
  (7, 'Manager', '[email protected]', '9000000007', '2019-01-07'),
  (8, 'John', '[email protected]', '9000000055', '2019-01-08'),
  (9, 'Merry', '[email protected]', '9000000088', '2019-01-09'),
  (10, 'Keliv', '[email protected]', '9000550088', '2019-01-10'),
  (11, 'Herry', '[email protected]', '9050550088', '2019-01-11'),
  (12, 'Mark', '[email protected]', '9050550998', '2019-01-12');

Setup Database Credentials

In this step, We need to connect our project to database. we need to go application/config/ and open database.php file in text editor. After open the file in text editor, We need to setup database credential in this file like below.

$db['default'] = array(
	'dsn'	=> '',
	'hostname' => 'localhost',
	'username' => 'root',
	'password' => '',
	'database' => 'demo',
	'dbdriver' => 'mysqli',
	'dbprefix' => '',
	'pconnect' => FALSE,
	'db_debug' => (ENVIRONMENT !== 'production'),
	'cache_on' => FALSE,
	'cachedir' => '',
	'char_set' => 'utf8',
	'dbcollat' => 'utf8_general_ci',
	'swap_pre' => '',
	'encrypt' => FALSE,
	'compress' => FALSE,
	'stricton' => FALSE,
	'failover' => array(),
	'save_queries' => TRUE
);

Create Controller

Now we need to create a controller name Chart.php. In this controller we will create some method/function. We will build some of the methods like :

• Index() – This is used to fetch the record from database and pass the data to view.

<?php

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

class Chart extends CI_Controller {

    public function __construct() {
        parent::__construct();
		// load model
        $this->load->database();
        $this->load->helper(array('url','html','form'));
    }
    public function mories_chart() {

      $dayQuery =  $this->db->query("SELECT DAYNAME(created_at) as y, COUNT(id) as a  FROM users WHERE date(created_at) > DATE_SUB(NOW(), INTERVAL 1 WEEK) AND MONTH(created_at) = '" . date('m') . "' AND YEAR(created_at) = '" . date('Y') . "' GROUP BY DAYNAME(created_at)");

      $record = $dayQuery->result();

      $data['day_wise'] = json_encode( $record );
     //print_r($data['day_wise']);die;
      $this->load->view('morris_chart',$data);

    }

}
?>

In this controller function, we fatch the record from database for showing the data on morris stacked and bar charts.

Create Views

Now we need to create morris_chart.php, go to application/views/ folder and create morris_chart.php file. Here put the below html code for showing data on pie charts.

<head>
<meta charset=utf-8 />
<title>Morris.js Bar and Stacked Chart With Codeigniter</title>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" integrity="sha384-Gn5384xqQ1aoWXA+058RXPxPg6fy4IWvTNh0E263XmFcJlSAwiGgFAW/dAiS6JXm" crossorigin="anonymous">

</head>
<body>
  <h3 class="text-primary text-center">
    Morris charts with Codeigniter
  </h3>
  <div class"row">
    <div  class="col-sm-6 text-center">
       <label class="label label-success">Bar Chart</label>
      <div id="bar-chart" ></div>
    </div>
    <div class="col-sm-6 text-center">
       <label class="label label-success">Bar stacked</label>
      <div id="stacked" ></div>
    </div>

  </div>
</body>

Implement Javascript code

Finally we will implement javascript code for showing a data on morris stacked and bar charts. Now we will put the code on script tag after the closing of body tag.

<script>
  var serries = JSON.parse(`<?php echo $day_wise; ?>`);
  console.log(serries);
  var data = serries,
    config = {
      data: data,
      xkey: 'y',
      ykeys: ['a'],
      labels: ['This Week Total Registered Users'],
      fillOpacity: 0.6,
      hideHover: 'auto',
      behaveLikeLine: true,
      resize: true,
      pointFillColors:['#ffffff'],
      pointStrokeColors: ['black'],
      lineColors:['gray','red']
  };

  //for mories bar chart
  config.element = 'bar-chart';
  Morris.Bar(config);

  //for stacked bar chart
  config.element = 'stacked';
  config.stacked = true;
  Morris.Bar(config);
</script>

In this script code, we have intialize the morris stacked and bar charts with php codeigniter and set the data on it.
