Laravel 9 AJAX Dependent Country State City Dropdown

Use the below given simple steps to create dependent country state city dropdown using jQuery ajax in laravel 9 apps:

  • Step 1 – Installing Laravel 9 Application
  • Step 2 – Configuring Database Details
  • Step 3 – Creating Model & Migration
  • Step 4 – Create Routes
  • Step 5 – Create Country State City Controller
  • Step 6 – Create Country State City Dropdown View
  • Step 7 – Implement Ajax Code For Country State City Dropdown
  • Step 8 – Start Development Server

Step 1 – Installing Laravel 9 Application

Execute the following command on terminal to install laravel 9 apps:

composer create-project --prefer-dist laravel/laravel demo

Step 2 – Configuring Database Details

Open your downloaded laravel app into any text editor. Then find .env file and configure database detail like following:

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=db name
DB_USERNAME=db user name
DB_PASSWORD=db password

Step 3 – Creating Model & Migration

Execute the following command on terminal to navigate to your project by using the following command:

cd / demo

Then create model and migration file by using the following command:

php artisan make:model Country
php artisan make:model State
php artisan make:model City

php artisan make:migration create_country_state_city_tables

The above command will create two files into your laravel country state city app, which is located inside the following locations:

  • /database/migrations/create_pictures_table.php

So, find create_country_state_city_tables .php file inside Demo/database/migrations/ directory. Then open this file and add the following code into function up() on this file:

<?php
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class CreateCountryStateCityTables extends Migration
{
    public function up()
    {
        Schema::create('countries', function (Blueprint $table) {
            $table->increments('id');
            $table->string('name');
            $table->timestamps();
        });
        Schema::create('states', function (Blueprint $table) {
            $table->increments('id');
            $table->string('name');
            $table->integer('country_id');            
            $table->timestamps();
        });
        Schema::create('cities', function (Blueprint $table) {
            $table->increments('id');
            $table->string('name');
            $table->integer('state_id');            
            $table->timestamps();
        });
    }
   public function down()
    {
       Schema::drop('countries');
       Schema::drop('states');
       Schema::drop('cities');
    }
}

Now, open again your terminal and type the following command on cmd to create tables into your selected database:

php artisan migrate

Step 4 – Create Routes

Open your web.php file, which is located inside routes directory. Then add the following routes into web.php file:

use App\Http\Controllers\CountryStateCityController;


Route::get('country-state-city', [CountryStateCityController::class, 'index']);
Route::post('get-states-by-country', [CountryStateCityController::class, 'getState']);
Route::post('get-cities-by-state', [CountryStateCityController::class, 'getCity']);

Step 5 – Create Country State City Controller

Create Country State City controller by using the following command:

php artisan make:controller CountryStateCityController

The above command will create CountryStateCityController.php file, which is located inside /app/Http/Controllers/ directory.

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Validator,Redirect,Response;
use App\Models\{Country,State,City};

class CountryStateCityController extends Controller
{

    public function index()
    {
        $data['countries'] = Country::get(["name","id"]);
        return view('country-state-city',$data);
    }
    public function getState(Request $request)
    {
        $data['states'] = State::where("country_id",$request->country_id)
                    ->get(["name","id"]);
        return response()->json($data);
    }
    public function getCity(Request $request)
    {
        $data['cities'] = City::where("state_id",$request->state_id)
                    ->get(["name","id"]);
        return response()->json($data);
    }

}

Step 6 – Creating Crop Image Upload Blade View

<!DOCTYPE html>
<html lang="{{ str_replace('_', '-', app()->getLocale()) }}">
    <head>
        <meta charset="utf-8">
        <meta name="csrf-token" content="content">
        <meta name="viewport" content="width=device-width, initial-scale=1">
