Let’s get started.


Installation of Laravel 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, Learn Composer Installation Steps. 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 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 already installed at system.


Create Database & Connect

To create a database, either we can create via Manual tool of PhpMyadmin or by means of a mysql command.

CREATE DATABASE laravel_app;

To connect database with application, Open .env file from application root. Search for DB_ and update your details.

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=laravel_app
DB_USERNAME=root
DB_PASSWORD=root

Create Model and Migrations

Open project into terminal and run these commands.

$ php artisan make:model Country -m

It will create two files –

  • Model file Country.php at /app/Models folder.
  • Migration file 2021_06_27_151155_create_countries_table.php at /database/migrations folder.

Open Migration file 2021_06_27_151155_create_countries_table.php and write this complete code into it.

<?php

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

class CreateCountriesTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('countries', function (Blueprint $table) {
            $table->id();
            $table->char("iso", 2);
            $table->string("name", 50);
            $table->string("nicename", 50);
            $table->char("iso3", 3)->nullable();
            $table->smallInteger("numcode")->nullable();
            $table->integer("phonecode")->nullable();
        });
    }

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

Open Country.php model file and write this complete code into it.

<?php

namespace App\Models;

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

class Country extends Model
{
    use HasFactory;

    public $timestamps = false;
}

Run Migration

Back to terminal and run this command to run migration and create table.

$ php artisan migrate

It will run all migrations.


Insert Data into Table

As from migration we have created a table named as countries. We need some data into this table to test autocomplete search.

For data here we have the link of github.

Run the given mysql query to your database from this github link.

When you will run, you will get data something like this.


Create Controller

Back to terminal and run this command to create controller file.

$ php artisan make:controller SearchController

It will create SearchController.php file inside /app/Http/Controllers folder.

<?php

namespace App\Http\Controllers;

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

class SearchController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        return view('search');
    }
  
    /**
     * Show the form for creating a new resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function autocomplete(Request $request)
    {
        $input = $request->all();

        $data = Country::select(["id", "nicename"])
                ->where("nicename","LIKE","%{$input['query']}%")
                ->get();
   
      $countries = [];
      
      if(count($data) > 0){

            foreach($data as $country){
                $countries[] = array(
					"value" => $country->id,
					"label" => $country->nicename,
				);
            }
        }        
        return response()->json($countries);
    }
}

Add Routes

Open web.php file from /routes folder. Add these given routes into it.

//..

use App\Http\Controllers\SearchController;

Route::get('search', [SearchController::class, 'index'])->name('search');
Route::post('autocomplete', [SearchController::class, 'autocomplete'])->name('autocomplete');

//..
