Laravel Dynamically Add or Remove Input Fields jQuery

Step 1: Install Laravel App
Step 2: Add Database Details
Step 3: Create Migration & Model

Step 4: Add Routes
Step 5: Create Controller by Artisan
Step 6: Create Blade View

Step 7: Run Development Server

Step 1: Install Laravel App

First of all we need to create a fresh laravel project, download and install Laravel using the below command

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

1	composer create-project --prefer-dist laravel/laravel Blog

Step 2: Add Database Details

Now, lets create a MySQL database and connect it with laravel application. After creating database we need to set database credential in application’s .env file.

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

DB_CONNECTION=mysql

DB_HOST=127.0.0.1

DB_PORT=3306

DB_DATABASE=here your database name here

DB_USERNAME=here database username here

DB_PASSWORD=here database password here

Step 3: Create Migration & Model

Now, in this step we will create model and migration file. Please run the following command:

php artisan make:model Todo -m

1	php artisan make:model Todo -m

The above command will create one model name Todo.php and as well as one migration file for the Todos table.

Now go to database/migrations folder and open create_todos_table.php. Then update the following code into create_todos_table.php:

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

<?php

use Illuminate\Database\Migrations\Migration;

use Illuminate\Database\Schema\Blueprint;

use Illuminate\Support\Facades\Schema;

class CreateTodosTable extends Migration

{

/**

* Run the migrations.

* @return void

public function up()

{

Schema::create('todos', function (Blueprint $table) {

$table->id();

$table->string('title');

$table->timestamps();

});

}

/**

* Reverse the migrations.

* @return void

public function down()

{

Schema::dropIfExists('todos');

}

Now, run the migration to create database table using following artisan command:

php artisan migrate

1	php artisan migrate

Step 4: Create Route

After this, we need to define routes in “routes/web.php” file. Lets open “routes/web.php” file and add the following routes in it.

routes/web.php

Route::get('add-remove-input-fields', 'AddRemoveFieldController@index');
Route::post('add-remove-input-fields', 'AddRemoveFieldController@store');

1 2	Route::get('add-remove-input-fields', 'AddRemoveFieldController@index'); Route::post('add-remove-input-fields', 'AddRemoveFieldController@store');

Step 5: Generate Controller by Artisan

Now, lets create a controller named AddRemoveFieldController using command given below –

php artisan make:controller AddRemoveFieldController

1	php artisan make:controller AddRemoveFieldController

This command will create a controller named AddRemoveFieldController.php file.

Next, Navigate to app/http/controllers/ folder and open AddRemoveFieldController.php. Then add the following file uploading methods into your AddRemoveFieldController.php file:

<?php
namespace App\Http\Controllers;
 
use Illuminate\Http\Request;
 
use App\Todo;
 
use Illuminate\Support\Facades\Validator;
 
class AddRemoveFieldController extends Controller
{
    public function index() 
    {
        return view("add-remove-input-fields");
    }
    public function store(Request $request) {
 
       $data = [];
 
        foreach($request->input('title') as $key => $value) {
            $data["title.{$key}"] = 'required';
        }
 
        $validator = Validator::make($request->all(), $data);
 
        if ($validator->passes()) {
 
            foreach($request->input('title') as $key => $value) {
                Todo::create(['title'=>$value]);
            }
 
            return response()->json(['success'=>'true']);
        }
 
        return response()->json(['error'=>$validator->errors()->all()]);
  }
 
}

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Todo;

use Illuminate\Support\Facades\Validator;

class AddRemoveFieldController extends Controller

{

public function index()

{

return view("add-remove-input-fields");

}

public function store(Request $request) {

$data = [];

foreach($request->input('title') as $key => $value) {

$data["title.{$key}"] = 'required';

}

$validator = Validator::make($request->all(), $data);

if ($validator->passes()) {

foreach($request->input('title') as $key => $value) {

Todo::create(['title'=>$value]);

}

return response()->json(['success'=>'true']);

}

return response()->json(['error'=>$validator->errors()->all()]);

}

Step 6: Create Blade View

In this step, we will create one blade view file named add-remove-input-fields.blade.php.

Now, go to resources/views and create one file name add-remove-input-fields.blade.php Then update the following code into your add-remove-input-fields.blade.php file
