How to Get Records from Database with AngularJS in CodeIgniter

Data selection is required either to display information on the screen or use it for some data manipulation.

If you want to get records from the MySQL database using AngularJS in CodeIgniter then you need to create a method in the controller for handling the requests and return response.

1. Table structure

I am using users table in the demonstration.

CREATE TABLE `users` (
  `username` varchar(60) NOT NULL,
  `name` varchar(50) NOT NULL,
  `gender` varchar(10) NOT NULL,
  `email` varchar(60) NOT NULL

2. Configuration

Navigate to application/config/database.php and define Database connection.

$db['default'] = array(
 'dsn' => '',
 'hostname' => 'localhost',
 'username' => 'root', // Username
 'password' => '', // Password
 'database' => 'tutorial', // Database name
 '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

Default controller

Open application/config/routes.php and edit default_controller value to User.

$route['default_controller'] = 'User';

Load Database

To access the MySQL database require loading database library.

Open application/config/autoload.php and add the database in libraries array().

$autoload['libraries'] = array("database");

3. Model

Create Main_model.php file in application/models/ directory.

Define a single method –

getRecords() – Select all records from users table and return the response array.

Completed Code

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

class Main_model extends CI_Model {

  function getRecords(){

    // Select user records
    $q = $this->db->get('users');
    $results = $q->result_array();

    return $results;


4. Controller

Create User.php file in application/controllers/ directory.

Define 3 methods –

__construct() – Load url helper and Main_model model.

index() – Load user_view view.

getUsers() – This method call from the $http service request in AngularJS script.

Call getRecords() method of Main_model to fetch users list which returns an array. Convert the array to JSON format for return.

Completed Code

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

class User extends CI_Controller {

  public function __construct(){


    // load base_url

    // Load Model

  public function index(){


  // Call this method from AngularJS $http request
  public function getUsers(){
    // get data
    $data = $this->Main_model->getRecords();
    echo json_encode($data);


5. Download AngularJS

  • Download AngularJS from its Official website.
  • Create assets directory in the project root directory.
  • Store the downloaded script in assets/ directory.

6. View

Create user_view.php file in application/views/ directory.

Include angular.min.js in the <head> section and in the <table> display users list by looping on users object using ng-repeat directive.


Create a getUsers() method.

Send $http service request to <?= base_url() ?>index.php/User/getUsers and on the successfully callback assign in $scope.users object.

Completed Code

<!DOCTYPE html>
<html lang="en">
 <!-- AngularJS -->
 <script src='<?= base_url() ?>assets/angular.min.js'></script>
<body ng-app='myapp'>

  <div ng-controller='userCtrl'>
    <!-- User Records -->
    <table border='1' style='border-collapse: collapse;'>
     <tr ng-repeat='user in users'>
       <td>{{ user.username }}</td>
       <td>{{ }}</td>
       <td>{{ user.gender }}</td>
       <td>{{ }}</td>

 <!-- Script -->
 var fetch = angular.module('myapp', []);

 fetch.controller('userCtrl', ['$scope', '$http', function ($scope, $http) {
   $scope.getUsers = function(){
     method: 'get',
     url: '<?= base_url() ?>index.php/User/getUsers'
    }).then(function successCallback(response) {
      // Assign response to users object
      $scope.users =;

8. Conclusion

Define a method in the controller to get records from MySQL database and call it from the $http request in the Angular script.

You can use CDN link for including AngularJS script in the view.
