How To Morris Stacked and Bar Chart In Codeigniter 4 App

Step 1: Download Codeigniter 4 Project
Step 2: Basic Configurations
Step 3: Create a Table in the Database
Step 4: Setup Database Credentials
Step 5: Create a Controller
Step 6: Create a View
Step 7: Define Routes
Step 8: Start Development Server

Step 1: Download Codeigniter 4 Project

In this step, you will download the latest version of Codeigniter 4, Go to this link https://codeigniter.com/download Download Codeigniter 4 fresh new setup and unzip the setup in your local system xampp/htdocs/ . And change the download folder name “demo”

Step 2: Basic Configurations

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

Set Base URL like this

public $baseURL = 'http://localhost:8080';
To
public $baseURL = 'http://localhost/demo/';

Step 3: Create a Table in the Database

In this step, you need to create table in database and as well as insert some data to implement bar and stacked chart in codeiginter 4. So visit your phpmyadmin panel and execute the following sql query in it:

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');

Step 4: Setup Database Credentials

In this step, you need to connect our project to the database. you need to go app/Config/Database.php and open database.php file in text editor. After opening the file in a text editor, you need to set up database credentials in this file like below.

	public $default = [
		'DSN'      => '',
		'hostname' => 'localhost',
		'username' => 'root',
		'password' => '',
		'database' => 'demo',
		'DBDriver' => 'MySQLi',
		'DBPrefix' => '',
		'pConnect' => false,
		'DBDebug'  => (ENVIRONMENT !== 'production'),
		'cacheOn'  => false,
		'cacheDir' => '',
		'charset'  => 'utf8',
		'DBCollat' => 'utf8_general_ci',
		'swapPre'  => '',
		'encrypt'  => false,
		'compress' => false,
		'strictOn' => false,
		'failover' => [],
		'port'     => 3306,
	];

Step 5: Create a Controller

In this step, Visit app/Controllers and create a controller name MorrisChart.php. In this controller, you need to add the following methods into it:

<?php namespace App\Controllers;
use CodeIgniter\Controller;
use CodeIgniter\HTTP\RequestInterface;


class MorrisChart extends Controller
{

    public function index() {

        $db      = \Config\Database::connect();
        $builder = $db->table('users');   

        $query = $builder->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)");

      $data['day_wise'] = $query->getResult();
        
	    return view('home',$data);
    }

}

Step 6: Create a View

In this step, you need to create one view files name home.php and update the following code into your file:

<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">
<script src="https://code.jquery.com/jquery-3.3.1.min.js"></script> 
<script src="https://cdnjs.cloudflare.com/ajax/libs/raphael/2.1.2/raphael-min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/morris.js/0.5.0/morris.min.js"></script>
</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, need to implement javascript code for showing a data on morris bar chart. 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>

Step 7: Define Routes

In this step, you need to create a route that renders the table into the view, place the following code in app/Config/Routes.php file.

$routes->get('/', 'MorrisChart::index');

Step 8: Start Development Server

In this step, open your terminal and execute the following command to start development sever:

php spark serve

Then, Go to the browser and hit below the URL:

http://localhost:8080

In this codeigniter 4 morris stacked chart and bar chart tutorial, you have successfully fetched the record from a database and display it on the morris charts in codeigniter 4 app.
