Inside this article we will see chatbot conversation integration in laravel 8 using botman. Botman is a composer package. After installation automatically it will provide the interface of chat and it’s internal functions.

We need to install botman and botman-driver composer package.

Here, we will see the step by step guide to work with Botman chatbot in laravel 8.

Let’s get started.


Laravel Installation

We will create laravel project using composer. So, please make sure your system should have composer installed. If not, may be this article will help you to Install composer in system.

Here is the command to create a laravel project-

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

To start the development server of Laravel –

$ php artisan serve

URL: http://127.0.0.1:8000

Assuming laravel already installed inside your system.


Install Botman and Botman Driver

To get the functions of chatbot, next we need to install botman into laravel setup.

Open project in terminal and run this command.

composer require botman/botman

After installation of this package, next run this command to install botman driver.

composer require botman/driver-web

Create Configuration File (Optional)

These steps are optional. These configuration file for driver and cache.

Let’c create a folder with name botman inside /config directory. Create two files inside /config/botman.

  • config.php
  • web.php

Open /config/botman/config.php

<?php

return [
    'conversation_cache_time' => 40,
    'user_cache_time' => 30,
];

Open /config/botman/web.php

<?php

return [

    'matchingData' => [
        'driver' => 'web',
    ],
];

Create Controller

Open project into terminal and run this artisan command to create controller class file.

$ php artisan make:controller BotManController

It will create a file with name BotManController.php at /app/Http/Controllers folder.

Open BotManController.php and write this complete code into it.

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Botman\OnboardingConversation;

class BotManController extends Controller
{
    /**
     * Place your BotMan logic here.
     */
    public function handle()
    {
        $botman = app('botman');

        $botman->hears('{message}', function ($botman, $message) {

            $botman->startConversation(new OnboardingConversation);
        });

        $botman->listen();
    }
}
  • All conversation logics, we have separated into a class file OnboardingConversation.php.
  • Create a folder with any name, example Botman inside /app folder.
  • Create a file OnboardingConversation.php inside /app/Botman folder. This file will contain all conversation logic like Asking, reply, save data etc.

Create Conversation Class File

Create a file OnboardingConversation.php inside /app/Botman.

Open file and write this complete code into it.

<?php

namespace App\Botman;

use BotMan\BotMan\Messages\Conversations\Conversation;
use BotMan\BotMan\Messages\Incoming\Answer;

class OnboardingConversation extends Conversation
{
    protected $name;

    protected $email;

    protected $query;

    public function askName()
    {
        $this->ask('Hi! What is your name?', function(Answer $answer) {
            // Save result
            $this->name = $answer->getText();

            $this->say('Nice to meet you '.$this->name);
            $this->askEmail();
        });
    }

    public function askEmail()
    {
        $this->ask('One more thing - what is your email address?', function(Answer $answer) {
            // Save result
            $this->email = $answer->getText();

            $this->say('Great - that is all we need, '.$this->name);
            $this->askHelp();
        });
    }

    public function askHelp()
    {
        $this->ask('How can I help you?', function(Answer $answer) {
            // Save result
            $this->query = $answer->getText();

            $this->say('Your query has been forwarded, we will contact you soon.');
        });
    }

    public function run()
    {
        // This will be called immediately
        $this->askName();
    }
}
  • Here, inside this logic we are asking for Name, email, and query from user.
  • We have all different different methods to fire each query.
  • To save data into database also we can use Laravel model.

Add Route

Open web.php from /routes folder. Add this route into it.

use App\Http\Controllers\BotManController;

//...

Route::match(['get', 'post'], 'botman', [BotManController::class, 'handle']);

Create Blade File

Open any of the view file from your application. I am opening the default view file i.e welcome.blade.php

Add this simple code into it. This code will creates a interface of Chatbox.

//...

<link rel="stylesheet" type="text/css" href="https://cdn.jsdelivr.net/npm/botman-web-widget@0/build/assets/css/chat.min.css">
<script>
  var botmanWidget = {
  aboutText: 'Write Something',
  introMessage: "✋ Hi! I'm form Online Web Tutor"
  };
</script>

<script src='https://cdn.jsdelivr.net/npm/botman-web-widget@0/build/js/widget.js'></script>
