Codeigniter 3 and AngularJS CRUD with Search and Pagination Example.

By Hardik Savani | February 21, 2016 | | 240698 Viewer | Category : PHP Codeigniter AngularJS


In This tutorial i want to show you how to create CRUD(Create, Read, Update, Delete) using AngularJS in Codeigniter. I added few step to create create, edit, delete, lists, search and pagination application in your Codeigniter framework. In this tutorial through you can make simple crud, search and pagination module and easily use in your codeigniter project. I am going to show preview of items module that we will do using angularJS and Codeigniter 3.

Preview:

Step 1: Create items table

In this first step we have to configration of our Codeigniter 3 project, so first go on application/config/database.php, In this file you have to add your database name, username and password, then we have to create items table in following sql query :

CREATE TABLE IF NOT EXISTS `items` (

`id` int(10) unsigned NOT NULL AUTO_INCREMENT,

`title` varchar(255) COLLATE utf8_unicode_ci NOT NULL,

`description` text COLLATE utf8_unicode_ci NOT NULL,

`created_at` timestamp NULL DEFAULT NULL,

`updated_at` timestamp NULL DEFAULT NULL,

PRIMARY KEY (`id`)

) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci AUTO_INCREMENT=16 ;

Step 2: Route file

In this step you have to add some route in your route file.So first we will create templates route, templates route through we will get html template for our application, Then we will create other route for items modules for lists, create, edit, update and delete.so put the bellow content in route file:

application/config/routes.php

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

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

$route['404_override'] = '';

$route['translate_uri_dashes'] = FALSE;

$route['templates/(:any)'] = "templates/view/$1";

$route['items'] = "items/index";

$route['itemsCreate']['post'] = "items/store";

$route['itemsEdit/(:any)'] = "items/edit/$1";

$route['itemsUpdate/(:any)']['put'] = "items/update/$1";

$route['itemsDelete/(:any)']['delete'] = "items/delete/$1";

Step 3: Create controller

Ok, now first we have to create two new controller one for templates route and another for items route, so first create new templates controller in this path application/controllers/Templates.php and put bellow content in that file:

application/controllers/Templates.php

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

class Templates extends CI_Controller {

public function view($view)

{

$this->load->view('templates/'.$view);

}

}

Now create second controller for items modules, in this controller we will add function for listing, create, edit, update and delete. so create Items.php file in this path application/controllers/Items.php and put bellow code in this file:

application/controllers/Items.php

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

class Items extends CI_Controller {

public function index()

{

$this->load->database();

if(!empty($this->input->get("search"))){

$this->db->like('title', $this->input->get("search"));

$this->db->or_like('description', $this->input->get("search"));

}

$this->db->limit(5, ($this->input->get("page",1) - 1) * 5);

$query = $this->db->get("items");

$data['data'] = $query->result();

$data['total'] = $this->db->count_all("items");

echo json_encode($data);

}

public function store()

{

$this->load->database();

$_POST = json_decode(file_get_contents('php://input'), true);

$insert = $this->input->post();

$this->db->insert('items', $insert);

$id = $this->db->insert_id();

$q = $this->db->get_where('items', array('id' => $id));

echo json_encode($q->row());

}

public function edit($id)

{

$this->load->database();

$q = $this->db->get_where('items', array('id' => $id));

echo json_encode($q->row());

}

public function update($id)

{

$this->load->database();

$_POST = json_decode(file_get_contents('php://input'), true);

$insert = $this->input->post();

$this->db->where('id', $id);

$this->db->update('items', $insert);

$q = $this->db->get_where('items', array('id' => $id));

echo json_encode($q->row());

}

public function delete($id)

{

$this->load->database();

$this->db->where('id', $id);

$this->db->delete('items');

echo json_encode(['success'=>true]);

}

}

Step 4: use AngularJS

Now we will manage AngularJS route and controller, so first cretae "app" directory in your main folder (app)(I mean out side application folder) and create route.js(app/route.js) file for write all angular js. and put the bellow code in that file.

app/route.js

var app = angular.module('main-App',['ngRoute','angularUtils.directives.dirPagination']);

app.config(['$routeProvider',

function($routeProvider) {

$routeProvider.

when('/', {

templateUrl: 'templates/home.html',

controller: 'AdminController'

}).

when('/items', {

templateUrl: 'templates/items.html',

controller: 'ItemController'

});

}]);

now we have to create one folder in your app folder "controllers" and create one file "ItemController.js"(app/controllers/ItemController.js) file in that folder.

app/controllers/ItemController.js

app.controller('AdminController', function($scope,$http){

$scope.pools = [];

});

app.controller('ItemController', function(dataFactory,$scope,$http){

$scope.data = [];

$scope.pageNumber = 1;

$scope.libraryTemp = {};

$scope.totalItemsTemp = {};

$scope.totalItems = 0;

$scope.pageChanged = function(newPage) {

getResultsPage(newPage);

};

getResultsPage(1);

function getResultsPage(pageNumber) {

if(! $.isEmptyObject($scope.libraryTemp)){

dataFactory.httpRequest('/items?search='+$scope.searchText+'&page='+pageNumber).then(function(data) {

$scope.data = data.data;

$scope.totalItems = data.total;

$scope.pageNumber = pageNumber;

});

}else{

dataFactory.httpRequest('/items?page='+pageNumber).then(function(data) {

$scope.data = data.data;

$scope.totalItems = data.total;

$scope.pageNumber = pageNumber;

});

}

}

$scope.searchDB = function(){

if($scope.searchText.length >= 3){

if($.isEmptyObject($scope.libraryTemp)){

$scope.libraryTemp = $scope.data;

$scope.totalItemsTemp = $scope.totalItems;

$scope.data = {};

}

getResultsPage(1);

}else{

if(! $.isEmptyObject($scope.libraryTemp)){

$scope.data = $scope.libraryTemp ;

$scope.totalItems = $scope.totalItemsTemp;

$scope.libraryTemp = {};

}

}

}

$scope.saveAdd = function(){

dataFactory.httpRequest('itemsCreate','POST',{},$scope.form).then(function(data) {

$scope.data.push(data);

$(".modal").modal("hide");

});

}

$scope.edit = function(id){

dataFactory.httpRequest('itemsEdit/'+id).then(function(data) {

console.log(data);

$scope.form = data;

});

}

$scope.saveEdit = function(){

dataFactory.httpRequest('itemsUpdate/'+$scope.form.id,'PUT',{},$scope.form).then(function(data) {

$(".modal").modal("hide");

$scope.data = apiModifyTable($scope.data,data.id,data);

});

}

$scope.remove = function(item,index){

var result = confirm("Are you sure delete this item?");

if (result) {

dataFactory.httpRequest('itemsDelete/'+item.id,'DELETE').then(function(data) {

$scope.data.splice(index,1);

});

}

}

});

we have to create another folder "helper" in app directory for myHelper.js(app/helper/myHelper.js) file because that file will help to define helper function.

app/helper/myHelper.js

function apiModifyTable(originalData,id,response){

angular.forEach(originalData, function (item,key) {

if(item.id == id){

originalData[key] = response;

}

});

return originalData;

}

create one another folder "packages" and create file dirPagination.js(app/packages/dirPagination.js) and put code of following link:

dirPagination.js

Ok, at last you have create another one folder call "services" and create file myServices.js(app/services/myServices.js).

app/services/myServices.js

app.factory('dataFactory', function($http) {

var myService = {

httpRequest: function(url,method,params,dataPost,upload) {

var passParameters = {};

passParameters.url = url;

if (typeof method == 'undefined'){

passParameters.method = 'GET';

}else{

passParameters.method = method;

}

if (typeof params != 'undefined'){

passParameters.params = params;

passParameters.params = params;

}

if (typeof dataPost != 'undefined'){

passParameters.data = dataPost;

}

if (typeof upload != 'undefined'){

passParameters.upload = upload;

}

var promise = $http(passParameters).then(function (response) {

if(typeof response.data == 'string' && response.data != 1){

if(response.data.substr('loginMark')){

location.reload();

return;

}

$.gritter.add({

title: 'Application',

text: response.data

});

return false;

}

if(response.data.jsMessage){

$.gritter.add({

title: response.data.jsTitle,

text: response.data.jsMessage

});

}

return response.data;

},function(){

$.gritter.add({

title: 'Application',

text: 'An error occured while processing your request.'

});

});

return promise;

}

};

return myService;

});

Step 5: Create View

This is a last step and you have to modify first welcome_message.php file for theme setting, so let's modify welcome_message.php(application/views/welcome_message.php) and put following code :

application/views/welcome_message.php

<html lang="en">

<head>

<title>Codeigniter 3</title>

</head>

<body ng-app="main-App">

<nav class="navbar navbar-default">

<div class="container-fluid">

<div class="navbar-header">

<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1">

<span class="sr-only">Toggle Navigation</span>

<span class="icon-bar"></span>

<span class="icon-bar"></span>

<span class="icon-bar"></span>

</button>

<a class="navbar-brand" href="#">Codeigniter 3</a>

</div>

<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">

<ul class="nav navbar-nav">

<li><a href="#/">Home</a></li>

<li><a href="#/items">Item</a></li>

</ul>

</div>

</div>

</nav>

<div class="container">

<ng-view></ng-view>

</div>

</body>

</html>

Ok, now we need to create templates folder in views folder and need to add three html file, i am going to create that so give name properly and add that.

1.application/views/templates/home.html

<h2>Welcome to Dashboard</h2>

2.application/views/templates/items.html

<div class="row">

<div class="col-lg-12 margin-tb">
