Inside this article we will learn about Laravel 8 DataTable Ajax Pagination with Search and Sort. We will create server side data listing in laravel 8 with all features of searching and sorting. Server side pagination using Ajax in Laravel 8.

Let’s get started.

Installation of Laravel 8 Application

Laravel Installation can be done in two ways.

  • Laravel Installer
  • By using composer

Laravel Installer

To install Laravel via Laravel installer, we need to install it’s installer first. We need to make use of composer for that.

$ composer global require laravel/installer

This command will install laravel installer at system. This installation is at global scope, so you type command from any directory at terminal. To verify type the given command –

$ laravel

This command will open a command palette of Laravel Installer.

To create ad install laravel project in system, 

$ laravel new blog

With the name of blog a laravel project will be created at your specified path.

By using composer

Alternatively, we can also install Laravel by Composer command create-project. If your system doesn’t has Composer Installed, Click here to Install Composer ? Here is the complete command to create a laravel project- 

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

After following these steps we can install a Laravel 8 application into system. To start the development server of Laravel – 

$ php artisan serve

This command outputs –

Starting Laravel development server: http://127.0.0.1:8000

Assuming laravel 8 already installed at system.

Connect Database with Laravel Application

To connect with the database, Open up .env file which will be at root of project.

  • .env (environment) File at root
DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=ajax_pagination
DB_USERNAME=root
DB_PASSWORD=root

Successfully, we have connected database to application.

Create Migration To Generate Table

To create migration file for table we need to run few simple php artisan command. Let’s say we need to table called students. Back to terminal, so command will be –

# Migration command to create table
$ php artisan make:migration create_students_table

Open up the migration file and do the following code –

<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

class CreateStudentsTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('students', function (Blueprint $table) {
            $table->id();
            $table->string("name", 120);
            $table->string("email", 50)->nullable();
            $table->string("mobile", 50)->nullable();
            $table->enum("branch", ["CSE", "Mechanical", "Civil", "Electrical", "IT"]);
            $table->timestamp("created_at")->useCurrent();
            $table->timestamp("updated_at")->useCurrent();
        });
    }

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

Next, we need to migrate into database. Back to terminal and type the command –

# Migrate all migrations to database
$ php artisan migrate

It will run all pending migrations & generate tables in database.

Generate Model & Factory Class Files

To generate a model, factory file separately, then we have php artisan command for each. But in case if we need to generate all these by the help of a single command, we also have. Back to terminal

# Command to generate Model& Factory (f)
$ php artisan make:model Student -f

After running this we should have these files and their locations.

  • Student.php Model at /app/Models/
  • StudentFactory.php at /database/factories/

Application Model Settings

Find Student.php Model at /app/Models/. Open up into editor and paste the given following code.

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Student extends Model
{
    use HasFactory;
    
    protected $fillable = [
        'name', 'email', 'mobile', 'branch',
    ];
}

Generating Test Data in Laravel

Open StudentFactory.php from /database/factories/

<?php

namespace Database\Factories;

use App\Models\Student;
use Illuminate\Database\Eloquent\Factories\Factory;

class StudentFactory extends Factory
{
    /**
     * The name of the factory's corresponding model.
     *
     * @var string
     */
    protected $model = Student::class;

    /**
     * Define the model's default state.
     *
     * @return array
     */
    public function definition()
    {
        return [
            "name" => $this->faker->name(),
            "email" => $this->faker->safeEmail,
            "mobile" => $this->faker->phoneNumber,
            "branch" => $this->faker->randomElement([
                "CSE", "Mechanical", "Civil", "Electrical", "IT",
            ])
        ];
    }
}

Loading Factory File into DatabaseSeeder

Open up DatabaseSeeder.php from /database/seeders/

<?php

namespace Database\Seeders;

use Illuminate\Database\Seeder;
use Database\Seeders\StudentSeeder;
use App\Models\Student;

class DatabaseSeeder extends Seeder
{
    /**
     * Seed the application's database.
     *
     * @return void
     */
    public function run()
    {
         \App\Models\Student::factory(100)->create();
    }
}

Now, Command to seed data

# Command to Seed Data
$ php artisan db:seed

When we run above command, then 100 test rows will be inserted into Model’s respective Database Table.

Configure Application Routes

Open web.php from /routes folder and write these codes into it.

<?php

use App\Http\Controllers\StudentsController;
use Illuminate\Support\Facades\Route;

Route::get('/', [StudentsController::class, "index"]);
Route::get('/students/getStudents/', [StudentsController::class, "getStudents"])->name('students.getStudents');

Create Application Controller

We need to create a controller for application. We are creating StudentsController.php file at /app/Http/Controllers/.

$ php artisan make:controller StudentsController

Open up the file paste the given code into it.

<?php

namespace App\Http\Controllers;

use App\Models\Student;
use Illuminate\Http\Request;

class StudentsController extends Controller
{
    public function index()
    {
        return view('students.index');
    }

    /* Process ajax request */
    public function getStudents(Request $request)
    {
        $draw = $request->get('draw');
        $start = $request->get("start");
        $rowperpage = $request->get("length"); // total number of rows per page

        $columnIndex_arr = $request->get('order');
        $columnName_arr = $request->get('columns');
        $order_arr = $request->get('order');
        $search_arr = $request->get('search');

        $columnIndex = $columnIndex_arr[0]['column']; // Column index
        $columnName = $columnName_arr[$columnIndex]['data']; // Column name
        $columnSortOrder = $order_arr[0]['dir']; // asc or desc
        $searchValue = $search_arr['value']; // Search value

        // Total records
        $totalRecords = Student::select('count(*) as allcount')->count();
        $totalRecordswithFilter = Student::select('count(*) as allcount')->where('name', 'like', '%' . $searchValue . '%')->count();

        // Get records, also we have included search filter as well
        $records = Student::orderBy($columnName, $columnSortOrder)
            ->where('students.name', 'like', '%' . $searchValue . '%')
            ->orWhere('students.email', 'like', '%' . $searchValue . '%')
            ->orWhere('students.branch', 'like', '%' . $searchValue . '%')
            ->select('students.*')
            ->skip($start)
            ->take($rowperpage)
            ->get();

        $data_arr = array();

        foreach ($records as $record) {

            $data_arr[] = array(
                "id" => $record->id,
                "name" => $record->name,
                "email" => $record->email,
                "mobile" => $record->mobile,
                "branch" => $record->branch,
            );
        }

        $response = array(
            "draw" => intval($draw),
            "iTotalRecords" => $totalRecords,
            "iTotalDisplayRecords" => $totalRecordswithFilter,
            "aaData" => $data_arr,
        );

        echo json_encode($response);
    }
}

Blade Template – Layout Settings

Create a folder students at /resources/views/. Inside this folder create file with the name of index.blade.php

Open up the file from /resources/views/students/index.blade.php and write the following code.
