How to create captcha code in Laravel 5?

Today, i want to share with you how to implement simple captcha code with refresh button in laravel 5 app form. In this tutorial you can simply use captcha with validation in your register form or login form as you want. i use mews library package for captcha in laravel 5.5 application, it will help to generate captcha image with proper validation.

As we know well, some time we need to add captcha code for security level, it will improve security of your application. Generally we implement captcha code in register and login form for prevent bots and crawler. So it will help you to integrate captcha code in laravel 5.5 application.

I use mews/captcha composer package for generate captcha code image. they also provide validation for captcha. it is very helpful package. So if you also want to create captcha in your php laravel app then follow bellow step and you will get layout like as bellow:

Preview:

Step 1 : Install Laravel 5 Application

we are going from scratch, So we need to download fresh Laravel 5.5 version application using bellow command, So open your terminal OR command prompt and run bellow command:

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

Step 2: Install mews Captcha Package

Here, we have to add mews Captcha package so one your cmd or terminal and fire bellow command:

composer require mews/captcha

After successfully install package, open config/app.php file and add service provider and alias.

config/app.php

'providers' => [

....

Mews\Captcha\CaptchaServiceProvider::class,

],

'aliases' => [

....

'Captcha' => Mews\Captcha\Facades\Captcha::class,

],

Step 3: Create Routes

here, we require to add three routes display login form, post login form and another for refresh captcha code. so open your routes/web.php file and add following route.

routes/web.php

Route::get('my-captcha', 'HomeController@myCaptcha')->name('myCaptcha');

Route::post('my-captcha', 'HomeController@myCaptchaPost')->name('myCaptcha.post');

Route::get('refresh_captcha', 'HomeController@refreshCaptcha')->name('refresh_captcha');

Step 4: Create HomeController Methods

Now we require to create HomeController and add new three methods as myCaptcha(), myCaptchaPost() and refreshCaptcha(). So let's create controller and then put bellow code:

routes/web.php

<?php


namespace App\Http\Controllers;


use Illuminate\Http\Request;


class HomeController extends Controller

{

/**

* Create a new controller instance.

*

* @return void

*/

public function myCaptcha()

{

return view('myCaptcha');

}


/**

* Create a new controller instance.

*

* @return void

*/

public function myCaptchaPost(Request $request)

{

request()->validate([

'email' => 'required|email',

'password' => 'required',

'captcha' => 'required|captcha'

],

['captcha.captcha'=>'Invalid captcha code.']);

dd("You are here :) .");

}


/**

* Create a new controller instance.

*

* @return void

*/

public function refreshCaptcha()

{

return response()->json(['captcha'=> captcha_img()]);

}

}

Step 5: Create View File

At last step, we have to simple create myCaptcha.blade.php file and need to write code there for generate bootstrap login form, jquery ajax code. So let's copy bellow code:

resources/views/myCaptcha.blade.php

<html lang="en">

<head>

<body>

<div class="container" style="margin-top: 50px">

<div class="panel panel-default">

<div class="panel-heading">Login</div>


<div class="panel-body">

<form class="form-horizontal" method="POST" action="{{ route('myCaptcha.post') }}">

{{ csrf_field() }}


<div class="form-group{{ $errors->has('email') ? ' has-error' : '' }}">

<label for="email" class="col-md-4 control-label">E-Mail Address</label>


<div class="col-md-6">

<input id="email" type="text" class="form-control" name="email" value="{{ old('email') }}">


@if ($errors->has('email'))

<span class="help-block">

<strong>{{ $errors->first('email') }}</strong>

</span>

@endif

</div>

</div>


<div class="form-group{{ $errors->has('password') ? ' has-error' : '' }}">

<label for="password" class="col-md-4 control-label">Password</label>


<div class="col-md-6">

<input id="password" type="password" class="form-control" name="password">


@if ($errors->has('password'))

<span class="help-block">

</span>

@endif

</div>

</div>


<div class="form-group{{ $errors->has('captcha') ? ' has-error' : '' }}">

<label for="password" class="col-md-4 control-label">Captcha</label>


<div class="col-md-6">

<div class="captcha">

<span>{!! captcha_img() !!}</span>

<button type="button" class="btn btn-success btn-refresh"><i class="fa fa-refresh"></i></button>

</div>

<input id="captcha" type="text" class="form-control" placeholder="Enter Captcha" name="captcha">


@if ($errors->has('captcha'))

<span class="help-block">

<strong>{{ $errors->first('captcha') }}</strong>

</span>

@endif

</div>

</div>


<div class="form-group">

<div class="col-md-8 col-md-offset-4">

<button type="submit" class="btn btn-primary">

Submit

</button>

</div>

</div>

</form>

</div>

</div>

</div>

</div>

</body>


<script type="text/javascript">


$(".btn-refresh").click(function(){

$.ajax({

type:'GET',

url:'/refresh_captcha',

success:function(data){

$(".captcha span").html(data.captcha);

}

});

});


</script>


</html>
