In this example, we will create a posts table using migration. Then, we will create a data model for the posts and a factory class to create dummy post data. Finally, we will create a route to load posts and write the code for auto-loading more data on button click event using jQuery AJAX. Let's take a look at a simple step-by-step example.

Step for Laravel 12 Load More Data on Scroll Event Example

• Step 1: Install Laravel 12
• Step 2: MySQL Database Configuration
• Step 3: Create Migration
• Step 4: Create Model
• Step 5: Create Factory Class
• Step 6: Create Route
• Step 7: Create Controller
• Step 8: Create View Files
• Run Laravel App

Step 1: Install Laravel 12

This step is not required; however, if you have not created the Laravel app, then you may go ahead and execute the below command:

composer create-project laravel/laravel example-app

Step 2: MySQL Database Configuration

In Laravel 12, there is a default database connection using SQLite, but if we want to use MySQL instead, we need to add a MySQL connection with the database name, username, and password to the `.env` file.

.env

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=here your database name(blog)
DB_USERNAME=here database username(root)
DB_PASSWORD=here database password(root)

Step 3: Create Migration

Here, we will create a new migration for adding a new table posts in the users table. So let's run the following command:

php artisan make:migration create_posts_table

After this command, you will find one file in the following path "database/migrations," and you have to put the below code in your migration file to create the posts table.

<?php
  
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
  
return new class extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('posts', function (Blueprint $table) {
            $table->id();
            $table->string('title');
            $table->string('slug');
            $table->text('body');
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('posts');
    }
};

Now you have to run this migration with the following command:

php artisan migrate

Step 4: Create Model

After creating the "posts" table, you should create the Post model for posts. First, create a file in this path app/Models/Post.php and put the following content in the Post.php file:

app/Models/Post.php

<?php
    
namespace App\Models;
    
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
    
class Post extends Model
{
    use HasFactory;
   
    /**
     * Write code on Method
     *
     * @return response()
     */
    protected $fillable = [
        'title', 'body', 'slug'
    ];
}

Step 5: Create Factory Class

This step explains how to generate dummy data using a factory; this data loads dynamically on page scroll:

php artisan make:factory PostFactory --model=Post

Further, put the below code in database\factories\PostFactory.php:

database\factories\PostFactory.php

<?php
    
namespace Database\Factories;
    
use Illuminate\Database\Eloquent\Factories\Factory;
use App\Models\Post;
use Illuminate\Support\Str;
    
/**
 * @extends \Illuminate\Database\Eloquent\Factories\Factory<\App\Models\Post>
 */
class PostFactory extends Factory
{
    /**
     * The name of the factory's corresponding model.
     *
     * @var string
     */
    protected $model = Post::class;
      
    /**
     * Define the model's default state.
     *
     * @return array
     */
    public function definition(): array
    {
        return [
            'title' => $this->faker->text(),
            'slug' => Str::slug($this->faker->text()),
            'body' => $this->faker->paragraph()
        ];
    }
}

Open the terminal and execute the commands below to generate the test data:

php artisan tinker

Post::factory()->count(20)->create()

Step 6: Create Route

In this step, we need to create routes for displaying posts and getting posts. So, open your "routes/web.php" file and add the following route.

routes/web.php

<?php
  
use Illuminate\Support\Facades\Route;
  
use App\Http\Controllers\PostController;
    
Route::get('posts',[PostController::class,'index'])->name('posts.index');

Step 7: Create Controller

Here, we need to create a new controller, PostController, with an index method to display the posts view and return data. So let's put the code below.

app/Http/Controllers/PostController.php

<?php
     
namespace App\Http\Controllers;
     
use Illuminate\Http\Request;
use App\Models\Post;
     
class PostController extends Controller
{
  
    /**
     * Write code on Method
     *
     * @return response()
     */
    public function index(Request $request)
    {
        $posts = Post::paginate(10);
  
        if ($request->ajax()) {
            $view = view('data', compact('posts'))->render();
  
            return response()->json(['html' => $view]);
        }
  
        return view('posts', compact('posts'));
    }
}

Step 8: Create View Files

In the last step, let's create `posts.blade.php` and `data.blade.php` for displaying the posts list and put the following code:

resources/views/posts.blade.php

<!DOCTYPE html>
<html lang="{{ str_replace('_', '-', app()->getLocale()) }}">
<head>
    <meta name="csrf-token" content="{{ csrf_token() }}">
    <title>Load More Data on Button Click using JQuery Laravel - ItSolutionStuff.com</title>

    <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/6.4.0/css/all.min.css" />
</head>
<body>
      
<div class="container mt-5" style="max-width: 750px">

    <div id="data-wrapper">

    <div class="text-center">

    var ENDPOINT = "{{ route('posts.index') }}";
    var page = 1;
  
    $(".load-more-data").click(function(){
        page++;
        infinteLoadMore(page);
    });
  
    /*------------------------------------------
    --------------------------------------------
    call infinteLoadMore()
    --------------------------------------------
    --------------------------------------------*/
    function infinteLoadMore(page) {
        $.ajax({
                url: ENDPOINT + "?page=" + page,
                datatype: "html",
                type: "get",
                beforeSend: function () {
                    $('.auto-load').show();
                }
            })
            .done(function (response) {
                if (response.html == '') {
                    $('.auto-load').html("We don't have more data to display :(");
                    return;
                }

                $('.auto-load').hide();
                $("#data-wrapper").append(response.html);
            })
            .fail(function (jqXHR, ajaxOptions, thrownError) {
                console.log('Server error occured');
            });
    }
</script>
</body>
</html>

resources/views/data.blade.php

@foreach ($posts as $post)
<div class="card mb-2"> 
    <div class="card-body">{{ $post->id }} 
        <h5 class="card-title">{{ $post->title }}</h5>
