Laravel 6 REST API Using Passport Package

January 30, 2020 by Webprepration Leave a Comment

In this post, I am going to explain “how to create rest api with authentication using passport” in laravel 6 application. Rest API is must be used when you are working with mobile application. when your application is preferred for a web app and the mobile app then you must have to create API for your mobile app development.

However, Laravel provides an easy way to create Rest API using the passport package. if you need to authentication in your mobile app then you can easily do it using a passport. Laravel 6 Passport provides a way to create an auth token for validating users.

Web services

web service is very important when you are creating web and mobile apps.

How to Create Rest API with Authentication Using Passport

If you require to create API for mobile application As we know laravel is the most popular framework for API creation. If you are beginners and don’t know what is API and web services then you are the right place. In this article I will show how to create API and Authentication for mobile APPs.i will show you step by step build restful API authentication using eloquent API resources in laravel 6.

Follow bellow a few steps to create a restful API example in laravel 6 app.

Register API
Login API
User Details API

Above three API, you can simply get by following a few steps. It is from scratch so just follow the below steps, at last, I attach a screenshot of the API test.

Step 1:- In the first step required to install fresh laravel using below command, So open your terminal or command prompt and run command.


composer create-project --prefer-dist laravel/laravel APITest

composer create-project --prefer-dist laravel/laravel APITest

Step 2:- In this step to get install the passport package in laravel using below command


composer require laravel/passport

composer require laravel/passport

After passport installation package open config/app.php file and add service provider


LaravelPassportPassportServiceProvider::class,

LaravelPassportPassportServiceProvider::class,

Step 3:- The Passport service provider registers its own database migration directory with the framework, so you should migrate your database after registering the provider. The Passport migrations will create the tables your application needs to store clients and access tokens.


php artisan migrate

php artisan migrate

Next, you should run the passport:install command. This command will create the encryption keys needed to generate secure access tokens. In addition, the command will create “personal access” and “password grant” clients which will be used to generate access tokens.


php artisan passport:install

php artisan passport:install

Step 4:- In this step we have to configure passport, So just follow three given file changes.

firest we need to add the LaravelPassportHasApiTokens trait to your AppUsermodel. This trait will provide a few helper methods to your model which allow you to inspect the authenticated user’s token and scopes.

App/User.php


<?php


namespace App;


use LaravelPassportHasApiTokens;
use IlluminateNotificationsNotifiable;
use IlluminateFoundationAuthUser as Authenticatable;


class User extends Authenticatable
{
    use HasApiTokens, Notifiable;


    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'name', 'email', 'password',
    ];


    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
        'password', 'remember_token',
    ];
}

<?php

namespace App;

use LaravelPassportHasApiTokens;

use IlluminateNotificationsNotifiable;

use IlluminateFoundationAuthUser as Authenticatable;

class User extends Authenticatable

{

use HasApiTokens, Notifiable;

/**

* The attributes that are mass assignable.

* @var array

protected $fillable = [

'name', 'email', 'password',

];

/**

* The attributes that should be hidden for arrays.

* @var array

protected $hidden = [

'password', 'remember_token',

];

}

app/Providers/AuthServiceProvider.php


<?php


namespace AppProviders;


use LaravelPassportPassport;
use IlluminateSupportFacadesGate;
use IlluminateFoundationSupportProvidersAuthServiceProvider as ServiceProvider;


class AuthServiceProvider extends ServiceProvider
{
    /**
     * The policy mappings for the application.
     *
     * @var array
     */
    protected $policies = [
        'AppModel' => 'AppPoliciesModelPolicy',
    ];


    /**
     * Register any authentication / authorization services.
     *
     * @return void
     */
    public function boot()
    {
        $this->registerPolicies();
        Passport::routes();
    }
}

<?php

namespace AppProviders;

use LaravelPassportPassport;

use IlluminateSupportFacadesGate;

use IlluminateFoundationSupportProvidersAuthServiceProvider as ServiceProvider;

class AuthServiceProvider extends ServiceProvider

{

/**

* The policy mappings for the application.

* @var array

protected $policies = [

'AppModel' => 'AppPoliciesModelPolicy',

];

/**

* Register any authentication / authorization services.

* @return void

public function boot()

{

$this->registerPolicies();

Passport::routes();

}

config/auth.php


<?php


return [
    .....
    'guards' => [
        'web' => [
            'driver' => 'session',
            'provider' => 'users',
        ],
        'api' => [
            'driver' => 'passport',
            'provider' => 'users',
        ],
    ],
    .....
]

<?php

return [

.....

'guards' => [

'web' => [

'driver' => 'session',

'provider' => 'users',

'api' => [

'driver' => 'passport',

'provider' => 'users',

.....

]

Step 5:- In this step, We will create API routes laravel provide api.php file for write web services routes So lets add new routes on that file.

routes/api.php


<?php


/*
|--------------------------------------------------------------------------
| API Routes
|--------------------------------------------------------------------------
|
| Here is where you can register API routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which

 
| is assigned the "api" middleware group. Enjoy building your API!
|
*/


Route::post('login', 'APIUserController@login');
Route::post('register', 'APIUserController@register');


Route::group(['middleware' => 'auth:api'], function(){
	Route::post('details', 'APIUserController@details');
});

<?php

|--------------------------------------------------------------------------

| API Routes

|--------------------------------------------------------------------------

| Here is where you can register API routes for your application. These

| routes are loaded by the RouteServiceProvider within a group which

| is assigned the "api" middleware group. Enjoy building your API!

Route::post('login', 'APIUserController@login');

Route::post('register', 'APIUserController@register');

Route::group(['middleware' => 'auth:api'], function(){

Route::post('details', 'APIUserController@details');

});

Step 6:- In this step first we have create new directory API on controller folder and create new controller in API directory, So let’s create UserController and put below code.

app/Http/Controllers/API/UserController.php


<?php


namespace AppHttpControllersAPI;


use IlluminateHttpRequest;
use AppHttpControllersController;
use AppUser;
use IlluminateSupportFacadesAuth;
use Validator;


class UserController extends Controller
{


    public $successStatus = 200;


    /**
     * login api
     *
     * @return IlluminateHttpResponse
     */
    public function login(){
        if(Auth::attempt(['email' => request('email'), 'password' => request('password')])){
            $user = Auth::user();
            $success['token'] =  $user->createToken('MyApp')->accessToken;
            return response()->json(['success' => $success], $this->successStatus);
        }
        else{
            return response()->json(['error'=>'Unauthorised'], 401);
        }
    }


    /**
     * Register api
     *
     * @return IlluminateHttpResponse
     */
    public function register(Request $request)
    {
        $validator = Validator::make($request->all(), [
            'name' => 'required',
            'email' => 'required|email',
            'password' => 'required',
            'c_password' => 'required|same:password',
        ]);


        if ($validator->fails()) {
            return response()->json(['error'=>$validator->errors()], 401);            
        }


        $input = $request->all();
        $input['password'] = bcrypt($input['password']);
        $user = User::create($input);
        $success['token'] =  $user->createToken('MyApp')->accessToken;
        $success['name'] =  $user->name;


        return response()->json(['success'=>$success], $this->successStatus);
    }


    /**
     * details api
     *
     * @return IlluminateHttpResponse
     */
    public function details()
    {
        $user = Auth::user();
        return response()->json(['success' => $user], $this->successStatus);
    }
}

<?php

namespace AppHttpControllersAPI;

use IlluminateHttpRequest;

use AppHttpControllersController;

use AppUser;

use IlluminateSupportFacadesAuth;

use Validator;

class UserController extends Controller

{

public $successStatus = 200;

/**

* login api

* @return IlluminateHttpResponse

public function login(){

if(Auth::attempt(['email' => request('email'), 'password' => request('password')])){

$user = Auth::user();

$success['token'] = $user->createToken('MyApp')->accessToken;

return response()->json(['success' => $success], $this->successStatus);

}

else{

return response()->json(['error'=>'Unauthorised'], 401);

}

/**

* Register api

* @return IlluminateHttpResponse

public function register(Request $request)

{

$validator = Validator::make($request->all(), [

'name' => 'required',

'email' => 'required|email',

'password' => 'required',

'c_password' => 'required|same:password',

]);

if ($validator->fails()) {

return response()->json(['error'=>$validator->errors()], 401);

}

$input = $request->all();

$input['password'] = bcrypt($input['password']);

$user = User::create($input);

$success['token'] = $user->createToken('MyApp')->accessToken;

$success['name'] = $user->name;

return response()->json(['success'=>$success], $this->successStatus);

}

/**

* details api

* @return IlluminateHttpResponse

public function details()

{

$user = Auth::user();

return response()->json(['success' => $user], $this->successStatus);

}

Now we are ready to run our API, So run below command


php artisan serve

php artisan serve

Now, we can simply test API using postman tool, I have test it and you can see screenshot.

How To Use CURL Post Request In CodeIgniter Curl Example

December 18, 2019 by Webprepration Leave a Comment

In this post, I am going to explain “How to use CURL post request in CodeIgniter”. it will be a help to use API using curl request in code-igniter. You can fire post request, get request, put request and delete request in curl CodeIgniter 3.

PHP CURL has some pre-built functions like curl_init(), curl_setopt(), curl_exec() etc. using these cURL functions to getting JSON data and we can use their data in our project. I don’t think you should use another library for this.

Sometimes we need to work with third-party APIs and web services at that time we need to use CURL for getting request, post requests, delete requests, put requests, etc. PHP curl will help to post request with parameters and headers, we can get JSON response.

Here, I will give you a very simple example of Codeigniter curl post and Codeigniter curl get request and also give you headers with authentication example on bellow of simple curl request example:


<?php
  
class Test extends CI_Controller {
   
    /**
     * Index Page for this controller.
     *
     */
    public function postExample()
    {
        /* API URL */
        $url = 'http://www.abc.com/api';
   
        /* Init cURL resource */
        $ch = curl_init($url);
   
        /* Array Parameter Data */
        $data = ['name'=>'Mohsin', 'email'=>'webprepration@gmail.com'];
   
        /* pass encoded JSON string to the POST fields */
        curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
            
        /* set the content type json */
        curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type:application/json'));
            
        /* set return type json */
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
            
        /* execute request */
        $result = curl_exec($ch);
             
        /* close cURL resource */
        curl_close($ch);

    }
    public function getExample()
    {
        /* API URL */
        $url = 'http://www.abc.com/api';
   
        /* Init cURL resource */
        $curl = curl_init($url);
   
       	curl_setopt_array($curl, array(
		    CURLOPT_URL => $url,
		    CURLOPT_RETURNTRANSFER => true,
		    CURLOPT_ENCODING => "",
		    CURLOPT_TIMEOUT => 30000,
		    CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
		    CURLOPT_CUSTOMREQUEST => "GET",
		    CURLOPT_HTTPHEADER => array(
		    	// Set Here Your Requesred Headers
		        'Content-Type: application/json',
		    ),
		));
            
        /* execute request */
        $result = curl_exec($curl);
             
        /* close cURL resource */
        curl_close($curl);

    }

}

<?php

class Test extends CI_Controller {

/**

* Index Page for this controller.

public function postExample()

{

/* API URL */

$url = 'http://www.abc.com/api';

/* Init cURL resource */

$ch = curl_init($url);

/* Array Parameter Data */

$data = ['name'=>'Mohsin', 'email'=>'webprepration@gmail.com'];

/* pass encoded JSON string to the POST fields */

curl_setopt($ch, CURLOPT_POSTFIELDS, $data);

/* set the content type json */

curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type:application/json'));

/* set return type json */

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

/* execute request */

$result = curl_exec($ch);

/* close cURL resource */

curl_close($ch);

}

public function getExample()

{

/* API URL */

$url = 'http://www.abc.com/api';

/* Init cURL resource */

$curl = curl_init($url);

curl_setopt_array($curl, array(

CURLOPT_URL => $url,

CURLOPT_RETURNTRANSFER => true,

CURLOPT_ENCODING => "",

CURLOPT_TIMEOUT => 30000,

CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,

CURLOPT_CUSTOMREQUEST => "GET",

CURLOPT_HTTPHEADER => array(

// Set Here Your Requesred Headers

'Content-Type: application/json',

));

/* execute request */

$result = curl_exec($curl);

/* close cURL resource */

curl_close($curl);

}

How to implement DataTables server-side in laravel

November 1, 2018 by Webprepration Leave a Comment

In this post, I will be show you the easiest way to implement DataTables server side processing in Laravel. Here I will show you how to fetch data using ajax in laravel and render that data in DataTable with searching, Pagination and sorting with server side processing.

This post is an extension to a previous post on DataTables, where we initiated data tables with basic initialization. As many readers suggested to make a tutorial on DataTables server-side. . In this post we have explain step by step. Because Jquery DataTables will add some advance features like quick search of table data, it will make automatic pagination without write of code, table column ordering, sorting of table column and many more.

Now before we start coding include Datatables CSS file and Javascript files from CDN in your view page as follows.


<link rel="stylesheet" type="text/css" href="https://cdn.datatables.net/v/dt/dt-1.10.12/datatables.min.css"/>

<script type="text/javascript" src="https://cdn.datatables.net/v/dt/dt-1.10.12/datatables.min.js"></script>

Now let’s understand what all tasks we need to do

We need to limit the size of the table. (By default 10,25,50 or 100 entries)
Now Implement search functionality and sort.
The Pagination task.

All above task will be done in the controller and it will be explained later in this tutorial.

Now let’s start coding.

In the view page code for HTML table is given below.


<div class="panel-body"> 
        <div class="panel-body">   
         <div class="row">         
         <table class="table table-bordered" id="institute_table" style="width:100%">

                      <thead>

                             <th>Id</th>

                             <th>Brand Name</th>
                             <th>Model Name</th>
<th>Description</th>
<th>Price</th>
<th>Action</th>

                        </thead>        

         </table> 
      </div>
        </div>

       </div>

<thead>

<th>Brand Name</th>

<th>Model Name</th>

<th>Description</th>

<th>Price</th>

<th>Action</th>

</thead>

</table>

</div>

Now we need to add javascript code, you can add that code in your view file or any javascript file which is include with this view. Please copy the given code and paste in your file


<script>

      $(document).ready(function(){

        // Data table for serverside

       $('#institute_table').DataTable({

            "processing": true,

            "serverSide": true,

            "ajax":{

                     "url": "{{ url('productList') }}",

                     "dataType": "json",

                     "type": "POST",

                     "data":{ _token: "{{csrf_token()}}",route:'products'}

                   },

            "columns": [

                { "data": "id" },

                { "data": "brand_name" },
{ "data": "model_name" },
{ "data": "description" },
{ "data": "price" },

                { "data": "action" }

            ],

            aoColumnDefs: [

            {

               bSortable: false,

               aTargets: [ -1 ]

            }

          ]  



        });
});
</script>

$(document).ready(function(){

// Data table for serverside

$('#institute_table').DataTable({

"processing": true,

"serverSide": true,

"ajax":{

"url": "{{ url('productList') }}",

"dataType": "json",

"type": "POST",

"data":{ _token: "{{csrf_token()}}",route:'products'}

"columns": [

{ "data": "id" },

{ "data": "brand_name" },

{ "data": "model_name" },

{ "data": "description" },

{ "data": "price" },

{ "data": "action" }

aoColumnDefs: [

{

bSortable: false,

aTargets: [ -1 ]

}

]

});

</script>

Note:- Don’t forgot to pass CSRF Token along with ajax POST request as above. Otherwise ajax occurs internal server 500, Laravel checks CSRF Token in all post request by default ensure maximum protection.

Now we need to create routes for list data and load view


Route::get('products','DemoController@products');
Route::post('productList','DemoController@productList');

Route::get('products','DemoController@products');

Route::post('productList','DemoController@productList');

Now create product model file, Please copy below code and paste


<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Prodcut extends Model
{
    
protected $table = 'proucts';
protected $fillable = ['brand_name','model_name','price','description'];
}

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Prodcut extends Model

{

protected $table = 'proucts';

protected $fillable = ['brand_name','model_name','price','description'];

}

Note: If you don’t know the basic concept of Laravel Eloquent ORM then all controller code may find little confusing to you. Please consider learning that before proceeding this tutorial.

Now create Demo controller file in app/Http/Controllers/DemoController.php


<?php
namespace App\Http\Controllers;


use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use PDF;
use App\Products;


class DemoController extends Controller
{

   
    function products(Request $request){
        return view('server_side_table');
    }
    function productList(Request $request){

       $columns = array( 
            0 =>'id', 
            1 =>'brand_name',
            2 =>'model_name',
            3 =>'description',
            4 =>'price',
        );  
        $totalData = Products::count();            
        $totalFiltered = $totalData;
        $limit = $request->input('length');
        $start = $request->input('start');
        $order = $columns[$request->input('order.0.column')];
        $dir = $request->input('order.0.dir');
            
        if(empty($request->input('search.value')))
        {            
            $institutes = Products::offset($start)
                         ->limit($limit)
                         ->orderBy($order,$dir)
                         ->get();
        }else {
            $search = $request->input('search.value'); 

            $institutes =  Products::where('id','LIKE',"%{$search}%")
                            ->orWhere('brand_name', 'LIKE',"%{$search}%")
->orWhere('model_name', 'LIKE',"%{$search}%")
->orWhere('price', 'LIKE',"%{$search}%")
                            ->offset($start)
                            ->limit($limit)
                            ->orderBy($order,$dir)
                            ->get();

            $totalFiltered = Products::where('id','LIKE',"%{$search}%")
                             ->orWhere('brand_name', 'LIKE',"%{$search}%")
->orWhere('model_name', 'LIKE',"%{$search}%")
->orWhere('price', 'LIKE',"%{$search}%")
                             ->count();
        }
        $data = array();
        if(!empty($institutes))
        {
            foreach ($institutes as $key=>$institute)
            {
                
                $nestedData['id'] = $key+1;
                $nestedData['brand_name'] = $institute->brand_name;
                $nestedData['model_name'] = $institute->model_name;
                $nestedData['price'] = $institute->price;
                $nestedData['description'] = $institute->description;
                $nestedData['action'] = '<a href="#" class="del"><span class="glyphicon glyphicon-trash"></span> 
</a><a href="#" class="edit"><span class="glyphicon glyphicon-edit"></span></a>';
                $data[] = $nestedData;
            }

        }
        $json_data = array(
        "draw"            => intval($request->input('draw')),  
        "recordsTotal"    => intval($totalData),  
        "recordsFiltered" => intval($totalFiltered), 
        "data"            => $data   
        );            
        echo json_encode($json_data); 
     }          
        
 
}

?>

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

Generate PDF from Html in Laravel

September 30, 2018 by Webprepration 1 Comment

In this tutorial, I am going to explain “How to create PDF from html in Laravel” by using laravel dompdf package.

There are lots of pdf packages that are using to generate pdf from html with CSS, you can easily set the beautiful layout for pdf file using css most of the packages support css in pdf.

Using laravel-dompdf library, you can easily generate pdf file in your Laravel web application.

When you are need to sending report in email from large amount of data then you can convert your html view in pdf file and attach that file with mail or if we work on big ERP level project on laravel, we require to generate PDF file for data from database table.

In this tutorials we are using on of the best package barryvdh/laravel-dompdf it provide very easy way to generate html to pdf in laravel.

We are explain all code step by step:-

Step 1:- First need to install dompdf package in our laravel application using following command.


composer require barryvdh/laravel-dompdf

composer require barryvdh/laravel-dompdf

Step 2:- After install DOM PDF package for laravel we must be configure, So just open your config/app.php file and set following value for providers array and aliases array


'providers' => [
	....
	Barryvdh\DomPDF\ServiceProvider::class,
],
'aliases' => [
	....
	'PDF' => Barryvdh\DomPDF\Facade::class,
],

'providers' => [

....

Barryvdh\DomPDF\ServiceProvider::class,

'aliases' => [

....

'PDF' => Barryvdh\DomPDF\Facade::class,

Step 3:- In this step we need to set route for generate view. So just open your app/Http/routes.php file and add following route.


Route::get('html-to-pdf','DemoController@pdfDownload');

Route::get('html-to-pdf','DemoController@pdfDownload');

Step 4:- Now we should create controller as DemoController in this path app/Http/Controllers/DemoController.php

This controller will manage data and generate pdf file, so put bellow content in controller file


<?php
namespace App\Http\Controllers;


use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use PDF;



class DemoController extends Controller
{


    function pdfDownload(Request $request){

        $pdf = PDF::loadView('pdf_view');
        $filename = time().'.pdf';
        return $pdf->download($filename);
    }
        
        
 
}

?>

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Http\Controllers\Controller;

use PDF;

class DemoController extends Controller

{

function pdfDownload(Request $request){

$pdf = PDF::loadView('pdf_view');

$filename = time().'.pdf';

return $pdf->download($filename);

}

Step 5:- In last step, we have to create view file “pdf_view.blade.php” for generate view and also pdf file, so create pdf_view file and put bellow code:


<html>
<head>
<style>
table {
    font-family: arial, sans-serif;
    border-collapse: collapse;
    width: 100%;
}

td, th {
    border: 1px solid #dddddd;
    text-align: left;
    padding: 8px;
}

tr:nth-child(even) {
    background-color: #dddddd;
}
</style>
</head>
<body>

<h2>HTML Table</h2>

<table>
  <tr>
    <th>Company</th>
    <th>Contact</th>
    <th>Country</th>
  </tr>
  <tr>
    <td>Alfreds Futterkiste</td>
    <td>Maria Anders</td>
    <td>Germany</td>
  </tr>
  <tr>
    <td>Centro comercial Moctezuma</td>
    <td>Francisco Chang</td>
    <td>Mexico</td>
  </tr>
  <tr>
    <td>Ernst Handel</td>
    <td>Roland Mendel</td>
    <td>Austria</td>
  </tr>
  <tr>
    <td>Island Trading</td>
    <td>Helen Bennett</td>
    <td>UK</td>
  </tr>
  <tr>
    <td>Laughing Bacchus Winecellars</td>
    <td>Yoshi Tannamuri</td>
    <td>Canada</td>
  </tr>
  <tr>
    <td>Magazzini Alimentari Riuniti</td>
    <td>Giovanni Rovelli</td>
    <td>Italy</td>
  </tr>
</table>

</body>
</html>

border-collapse: collapse;

width: 100%;

}

text-align: left;

padding: 8px;

}

tr:nth-child(even) {

Integrate Twitter Login in CodeIgnitor

July 23, 2018 by Webprepration Leave a Comment

In this article, I am going to explain “Twitter Login in CodeIgnitor”. I have already explain Twitter oAuth API integration in PHP. So now we don’t need to explain “How create Twitter APP”. If you don’t know So please just go through the link “Twitter oAuth login api using php” and get full specification with step by step. In this post explanation in short because I have already explain this topic.

Twitter oAuth is a third party API and we already know that CodeIgnitor has a third_party directory where we can manage all third party API. Whenever we need to integrate any third party API. In CodeIgnitor third party integration is very simple.

Let’s Start Coding

Step 1:- Before start coding we need to download twitter PHP library, I will use TwitterOAuthas the most popular and easy to use. We can install it from the command line with Composer in codeignitor third party directory.


composer require abraham/twitteroauth

composer require abraham/twitteroauth

Step 2 :- Now after installation we need go to the constant.php file and define Consumer Key and Consumer Secret

application/config/constant.php


define("Consumer_Key", "put your consumer key");
define("Consumer_Secret", "put your consumer secret");

define("Consumer_Key", "put your consumer key");

define("Consumer_Secret", "put your consumer secret");

Step 3:- Create a new file in libraries folder for custom twitter auth library like TwitterAuth.php, If you don’t know “How to create custom Library in CodeIgnitor” then just go through the link and read how to create library and load in codeIgnitor here

application/libraries/TwitterAuth.php


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

require_once APPPATH.'third_party/twitter-login/lib/autoload.php';
use Abraham\TwitterOAuth\TwitterOAuth;

class TwitterAuth
{

	protected $CI;

    public function __construct()
    {

    	$this->CI =& get_instance();
        $this->CI->load->library('session');        
        $this->connection= new TwitterOAuth(Consumer_Key, Consumer_Secret);        
       
    }
    public function getLogin(){

    	$this->request_token = $this->connection->oauth("oauth/request_token", array("oauth_callback" => base_url()."Dashboardblog/twitterResponse"));
    	// print_r($this->request_token);

        $_SESSION['oauth_token'] = $this->request_token['oauth_token'];
       $_SESSION['oauth_token_secret'] = $this->request_token['oauth_token_secret'];
       $url = $this->connection->url("oauth/authorize", array("oauth_token" => $this->request_token['oauth_token']));

       $this->CI->session->set_userdata('oauth_token', $this->request_token['oauth_token']);
		$this->CI->session->set_userdata('oauth_token_secret',$this->request_token['oauth_token_secret']);
    	
    	redirect($this->connection->url('oauth/authorize', array('oauth_token' => $this->request_token['oauth_token']), 'refresh'));

    }
    public function checkAuth(){

    	$this->connection = new TwitterOAuth(Consumer_Key, Consumer_Secret, $_SESSION['oauth_token'], $_SESSION['oauth_token_secret']);

		$this->access_token = $this->connection->oauth('oauth/access_token', array('oauth_verifier' => $_REQUEST['oauth_verifier'], 'oauth_token'=> $_GET['oauth_token']));

	    $this->connection = new TwitterOAuth(Consumer_Key, Consumer_Secret, $this->access_token['oauth_token'], $this->access_token['oauth_token_secret']);

	    $this->user_info = $this->connection->get('account/verify_credentials');

	    return $this->user_info;

    }
}

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

require_once APPPATH.'third_party/twitter-login/lib/autoload.php';

use Abraham\TwitterOAuth\TwitterOAuth;

class TwitterAuth

{

protected $CI;

public function __construct()

{

$this->CI =& get_instance();

$this->CI->load->library('session');

$this->connection= new TwitterOAuth(Consumer_Key, Consumer_Secret);

}

public function getLogin(){

$this->request_token = $this->connection->oauth("oauth/request_token", array("oauth_callback" => base_url()."Dashboardblog/twitterResponse"));

// print_r($this->request_token);

$_SESSION['oauth_token'] = $this->request_token['oauth_token'];

$_SESSION['oauth_token_secret'] = $this->request_token['oauth_token_secret'];

$url = $this->connection->url("oauth/authorize", array("oauth_token" => $this->request_token['oauth_token']));

$this->CI->session->set_userdata('oauth_token', $this->request_token['oauth_token']);

$this->CI->session->set_userdata('oauth_token_secret',$this->request_token['oauth_token_secret']);

redirect($this->connection->url('oauth/authorize', array('oauth_token' => $this->request_token['oauth_token']), 'refresh'));

}

public function checkAuth(){

$this->connection = new TwitterOAuth(Consumer_Key, Consumer_Secret, $_SESSION['oauth_token'], $_SESSION['oauth_token_secret']);

$this->access_token = $this->connection->oauth('oauth/access_token', array('oauth_verifier' => $_REQUEST['oauth_verifier'], 'oauth_token'=> $_GET['oauth_token']));

$this->connection = new TwitterOAuth(Consumer_Key, Consumer_Secret, $this->access_token['oauth_token'], $this->access_token['oauth_token_secret']);

$this->user_info = $this->connection->get('account/verify_credentials');

return $this->user_info;

}

Step 4:- Now go to your controller file and create any function and create view file for display twitter login button.


function index(){
    $this->load->view('twitter_auth');
  }

function index(){

$this->load->view('twitter_auth');

}

Now create twitter_auth.php file in view direactory, So just copy below code and paste in your view file.

application/views/twitter_auth.php


<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>Twitter Login using PHP</title>
<style>
.wrapper
 
{
 
	width: 800px;
 
	margin:0 auto;
 
}
 
h1
 
{
 
	font-size:28px;
 
	font-family:Gotham, "Helvetica Neue", Helvetica, Arial, sans-serif;
 
}
 
</style>
 
</head>
<body>
<div class="wrapper">
<h1><a href="https://webprepration.com/twitter-login-using-php/">Twitter Login using TwitterOAuth and PHP</a></h1>
<a href='<?php echo base_url(); ?>Dashboardblog/twitterAuth'><img src='<?php echo base_url(); ?>/demo/img/twitter_login_button.png' style='width: 47%;'></a>
</div>
 
</body>
 
</html>

<!doctype html>

<html>

<head>

<title>Twitter Login using PHP</title>

<style>

.wrapper

{

width: 800px;

margin:0 auto;

}

{

font-size:28px;

font-family:Gotham, "Helvetica Neue", Helvetica, Arial, sans-serif;

}

</style>

</head>

<body>

<h1><a href="https://webprepration.com/twitter-login-using-php/">Twitter Login using TwitterOAuth and PHP</a></h1>

<a href='<?php echo base_url(); ?>Dashboardblog/twitterAuth'><img src='<?php echo base_url(); ?>/demo/img/twitter_login_button.png' style='width: 47%;'></a>

</div>

</body>

</html>

Step 5:- Now create a new function twitterAuth in controller and load TwitterAuth Library and call login function of library.


 public function twitterAuth(){

     $this->load->library('TwitterAuth');

     $this->twitterauth->getLogin();     
    
  }

public function twitterAuth(){

$this->load->library('TwitterAuth');

$this->twitterauth->getLogin();

}

After that create a new function twitterResponse in controller for handle twitter response and insert user data in database.


 public function twitterResponse(){
    $this->load->library('TwitterAuth');
    $this->load->model('User_model');
    $twitter_data = $this->twitterauth->checkAuth();
    $res = $this->User_model->insert_userdata($twitter_data);
    if($res){
      $userdata = array('id'=>$res->id,'firstname'=>$res->firstname,'lastname'=>$res->lastname,'email'=>$res->email,'password'=>$res->password,'user_type'=>$res->user_type);
      $this->session->set_userdata($userdata);
    redirect(base_url('Dashboard/index'));
    }

public function twitterResponse(){

$this->load->library('TwitterAuth');

$this->load->model('User_model');

$twitter_data = $this->twitterauth->checkAuth();

$res = $this->User_model->insert_userdata($twitter_data);

if($res){

$userdata = array('id'=>$res->id,'firstname'=>$res->firstname,'lastname'=>$res->lastname,'email'=>$res->email,'password'=>$res->password,'user_type'=>$res->user_type);

$this->session->set_userdata($userdata);

redirect(base_url('Dashboard/index'));

}

Now create User_model in model directory for insert or update user details in database for proper login and set user data in session.

application/models/User_model.php


function check_tuser($data){
  
  $check = $this->checkTuser($data->id);  
  $insertdata = array('twitter_id'=>$data->id,
      'firstname'=>$data->screen_name,
      'location'=>$data->location,
      'profile_pic'=>$data->profile_image_url,
    );
  if(!empty($check) && count($check) > 0 ){    
    $this->db->where('id',$check->id);
    $this->db->update('register',$insertdata);
    return $check;
  }else{
    $this->db->insert('register',$insertdata);     
    return $this->checkTuser($this->db->insert_id());
  }  
        
}

function checkTuser($id){
  $this->db->select('*');
  $this->db->from("register");
  $this->db->where('twitter_id',$id);
  $qry = $this->db->get();
  return $qry->row();
}

function check_tuser($data){

$check = $this->checkTuser($data->id);

$insertdata = array('twitter_id'=>$data->id,

'firstname'=>$data->screen_name,

'location'=>$data->location,

'profile_pic'=>$data->profile_image_url,

);

if(!empty($check) && count($check) > 0 ){

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

$this->db->update('register',$insertdata);

return $check;

}else{

$this->db->insert('register',$insertdata);

return $this->checkTuser($this->db->insert_id());

}

function checkTuser($id){

$this->db->select('*');

$this->db->from("register");

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

$qry = $this->db->get();

return $qry->row();

}
