Let’s get started.

Laravel Installation

Open terminal and run this command to create a laravel project.

$ composer create-project laravel/laravel myblog

It will create a project folder with name myblog inside your local system.

To start the development server of laravel –

$ php artisan serve

URL: http://127.0.0.1:8000

Assuming laravel already installed inside your system.

Create Controller

Open project into terminal and type this command to create controller file.

$ php artisan make:controller AjaxController

This command will create a file i.e AjaxController.php inside /app/Http/Controllers folder.

Open this file and write this complete code into it.

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
// If work with model to save data to database
// Load model here like
// use App\Models\Post;

class AjaxController extends Controller
{
    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function myPost()
    {
        return view('my-post');
    }
     
    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function submitPost(Request $request)
    {
        // We are collecting all data submitting via Ajax
        $input = $request->all();
      
        /*
          $post = new Post;
          $post->name = $input['name'];
          $post->description = $input['description'];
          $post->status = $input['status'];
          $post->save();
        */
     	
        // Sending json response to client
        return response()->json([
            "status" => true,
            "data" => $input
        ]);
    }
}

Inside this above code, we have added a method which is processing ajax data. Also you can see in the comment section we have used Model concept and saved data into method as well.

Create Blade Template

Next,

Go inside /resources/views folder. Create a file called my-post.blade.php.

Open up the file and write this complete code into it.
