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 google_line_bar_chart() {

      $dayQuery =  $this->db->query("SELECT COUNT(id) as count,DAY(created_at) as day_date FROM users WHERE MONTH(created_at) = '" . date('m') . "'
        AND YEAR(created_at) = '" . date('Y') . "'
      GROUP BY DAY(created_at)"); 

      $data['day_wise'] = $dayQuery->result();
     ///print_r($data['day_wise']);die;
      $this->load->view('google_line_bar_chart',$data);

    }
    
}
?>

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

Create Views

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

<!Doctype html>
<html>
<head>
  <title>Google Date Wise Bar and Line Chart Codeigniter Tutorial</title>
  <script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script> 
  <script type="text/javascript">
      google.charts.load('visualization', "1", {
          packages: ['corechart']
      });
  </script>
</head>
<body>
<div class="row">
  <div class="col-md-12">
    <div id="line_date_wise" style="width: 900px; height: 500px; margin: 0 auto"></div>
    <div id="bar_date_wise" style="width: 900px; height: 500px; margin: 0 auto"></div>
  </div>  
</div>
</body>
</html>

Implement Javascript code

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

<script language="JavaScript">
  // Draw the pie chart for registered users month wise
  google.charts.setOnLoadCallback(lineChart);

  // Draw the pie chart for registered users year wise
  google.charts.setOnLoadCallback(barChart);
  
  //for month wise
  function lineChart() {

        /* Define the chart to be drawn.*/
        var data = google.visualization.arrayToDataTable([
            ['Date', 'Users Count'],
            <?php 
             foreach ($day_wise as $row){
             echo "['".$row->day_date."',".$row->count."],";
             }
             ?>
        ]);

        var options = {
          title: 'Day Wise Registered Users Of Line Chart',
          curveType: 'function',
          legend: { position: 'bottom' }
        };
        /* Instantiate and draw the chart.*/
        var chart = new google.visualization.LineChart(document.getElementById('line_date_wise'));
        chart.draw(data, options);
  }
  // for year wise
  function barChart() {

    /* Define the chart to be drawn.*/
    var data = google.visualization.arrayToDataTable([
        ['Date', 'Users Count'],
        <?php 
         foreach ($day_wise as $row){
         echo "['".$row->day_date."',".$row->count."],";
         }
         ?>
    ]);
    var options = {
        title: 'Date wise Registered Users Bar Chart',
        is3D: true,
    };
    /* Instantiate and draw the chart.*/
    var chart = new google.visualization.BarChart(document.getElementById('bar_date_wise'));
    chart.draw(data, options);
  }
</script>

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

Start Development server

For start development server, Go to the browser and hit below the url.

http://localhost/demo/chart/google_line_bar_chart
